Therefore, in the face of the above possible situations we can strictly screen the insulation board materials of cold storage,Port FrederickDesign and installation of medical cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low, and the air temperature, humidity and environmental requirements are relatively high. When selecting cold storage, attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good, the temperature in the cold storage is difficult to, which is easy to cause the deterioration of products in the cold storage, or the refrigeration compressor in the cold storage often works, wasting more resources and increasing the cost.

Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration, because the temperature difference inside and outside the board is large, and the temperature will disperse, which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.Which one is better,Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction,Port FrederickPharmaceutical cold storage, fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as cold storage.Air valve leakage and ring leakage will not only affect the rise of exhaust temperature of fresh-keeping warehouse, but also change the interstage pressure. As long as the compression ratio is higher than the normal value, the exhaust temperature will rise.Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large and I found that it is cheap to replicate cold through actual field investigation.Port Frederick,The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, and pay attention to the waterproof of the lamp.In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.During the installation of cold storage board in cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored, and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process, so as to waste resources and increase the cost.

The overall construction achievements of the cold storage project have been put into use, and the service life can reach years.The construction of small cold storage is widely used in life such as food industry, manufacturing industry, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.Sonderborg ,How to judge whether the controlled atmosphere storage is bad and the effect is poor? Under the same conditions, but now it takes minutes. In this way, the refrigeration is obviously slow and the effect is poor, which will directly affect the use cost.The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, etc. according to the actual needs of cold storage circulation.Zaihran,Installation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications, and corresponding protection measures shall be taken for the installed equipment.Features of quick freezing warehouse: the quick freezing technology is advanced the frost free quick freezing method is adopted, the famous brand compressor and refrigeration accessories are configured and the automatic frost is adopted. The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the st century.In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, ventilating medical products may also emit some odors. Once these odors are stored in a certain quantity,Sonderborg Installation price of fruit and vegetable fresh-keeping cold storage, they will also have a certain impact on other products. Therefore, we must carry out regular ventilation in the process of daily use, so as to effectively reduce the storage time of products. If the medical cold storage project uses row tube refrigeration, the image of frosting may appear after use for a period of time. If we do not defrost in time, it will also affect the effect of. Therefore, I hope you must pay attention to defrosting.For the selection and preparation of the ground location of the cold storage, the design of the cold storage shall consider the necessary auxiliary engineering buildings and equipment, such as working intermediates, packaging and combing room, special tool warehouse, loading and unloading platform, etc.In order to maintain a constant low temperature in the cold storage,Sonderborg Pharmaceutical refrigeration equipment, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.How much does it cost?,The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall, ceiling, ventilation, and can monitor and record the temperature and humidity in the storage area.For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.With the increasing use of cold storage, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore, some small problems may be ignored during installation. According to the following understanding.

Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.Recommendation and consultation,Cold storage plate features: good thermal insulation performance, light weight, high strength, corrosion resistance, anti-aging, beautiful appearance.Material requisition for the installation requirements of the assembly fresh-keeping warehouse: according to the engineering design and construction material list, the materials shall be sent to the accessories warehouse, and the materials and accessories models shall be carefully checked.Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.Sonderborg ,Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid without hollow feeling, antifreeze load-bearing, moisture-proof, etc.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect,Sonderborg Installation of drug cold storage, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Cork board: cork board can be said to be a relatively primitive kind of cold storage. The thermal conductivity of cork board is relatively low, and it is easy to obtain, so it is not difficult to process, so it is generally used as the insulation board in some ordinary cold storage. If you want to pursue better thermal insulation performance, you have to look at the following materials.

The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, and the external surface temperature of the external wall changes sharply. For example, the insulation and sound insulation effects of polyurethane insulation board are relatively good, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next, let's understand the physical properties of polyurethane insulation board.Svenberg,The location temperature, temperature difference and other main parameters of fresh-keeping warehouse equipment wholesale shall be set according to the specific situation of the frozen warehouse, and the main parameters cannot be changed at will. All kinds of cold storage installation, cold storage installation,SvenbergPreservation technology of vegetables in cold storage, cold storage construction, fruit preservation cold storage, medical cold storage formal qualification, welcome to telephone inquiry, sincerely invite cooperation! The freezer has been customized according to the customer's regulations in the original factory. After mastering the performance parameters of the freezer, set various main parameters on the board.Danfoss thermal valve is adopted for the thermal valve of the cold storage, with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature, and can be remotely controlled. When the temperature exceeds the specified range does not need special people to operate, it will automatically alarm, which is of great significance to the proper preservation of the cold storage.Conakry,Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example,SvenbergInstallation freezer price, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is to form a vapor barrier layer.On the basis of cold storage and preservation, the quick-frozen warehouse increases the regulation of gas composition, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables. Generally, controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?

Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, column, support steel frame, etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.Honest management,Goods are imported and exported frequently and the throughput is large according to the requirements of production and operationWith the development of the times, refrigeration devices are becoming more and more common. All aspects of life are inseparable from its use. Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need to grasp its key points in the production process of cold storage.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m, the thermal conductivity is only . ~ .w / (m.k), which is the lowest among all thermal insulation materials at present.

Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Installation materials,It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.The type of cold storage to be built in the cold storage type shall be determined according to the type of circulating goods. For example, a cold storage that only circulates vegetables can only establish a fresh-keeping cold storage. If there are many kinds of circulating commodities and large differences in storage temperatures, a cold storage of refrigeration + freezing will be established. As for the size of the cold storage, it shall be determined according to the type quantity, frequency, cycle, whether to use shelves for stacking, etc. For example, for fruits and vegetables packed in cartons,ZotgumHow long can the fruit be kept fresh in the cold storage, refer to the storage capacity of -kg per cubic meter, andConnect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.Zotgum,Relative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important, from centrifugal humidification to high-pressure micro fog humidification, gas-water mixed humidification, to the current ultrasonic humidifier. The utility model has the advantages of small particles, uniform humidification, no freezing and blocking, which is essentially different from other humidifiers in the market: fully closed circulation that is, take the gas in the warehouse, return to the warehouse through the humidifier and isolate it from the outside air.The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.Preparation, prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model, and start the installation of cold storage after confirmation.

The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof, waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.Roskeller,During the use of controlled atmosphere storage, it must be maintained on time and scientifically. No matter how good the equipment is, without scientific use and maintenance, its service life and effect will be discounted.The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.Binnish,RoskellerInstallation and price of small cold storage,In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, the building materials of the cold storage and the structure of each part of the cold storage should have sufficient frost resistance.However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.Cold storage, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.

The overall construction achievements of the cold storage project have been put into use, and the service life can reach years.The selection of wires shall have a safety factor, and the temperature of the wire surface shall not exceed ℃ during unit operation or defrosting.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Discount,Secondly, since the cooling of the compressor is not continuous, the multi work operation at night can be selected if possible. When working at night, the external temperature is low, the cooling water temperature is reduced, and the condensation pressure and condensation temperature are reduced. The cooling capacity of the sampling system, coupled with the equal role of the cold storage board, reduces the power operation of the compressor and achieves the purpose of energy saving.As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.

The evaporator surface is too thick or too much dust and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low,The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, the mode of multiple heads in parallel can be considered.Heat pump, hot water, refrigeration and other fields. Supporting downstream products include: household air conditioner, multi on-line, modular machine,RoskellerWhich cold storage is installed, small water ground source heat pump, etc. At present, a single scroll refrigeration unit can achieve ~ HP.Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.Roskeller,The quick-frozen warehouse is easy to load and unload. All the plates and walls of the quick-frozen warehouse are produced by molds. You can choose tens of millions of products. Professional cold storage installation, installation of cold storage cold storage construction, fruit preservation cold storage, medical cold storage and transaction safety are guaranteed. Through internal concave convex groove connection, loading unloading and handling are convenient. The installation period is short. Small and medium-sized cold storage can be delivered in - days, The library body can be combined, separated or increased or decreased according to the needs of users.Cold storage,RoskellerWhere is a large cold storage, lack of refrigerant, low pressure too low, excessive air intake compressor jamming.The refrigerant charge is insufficient. At this time, just add enough refrigerant.

The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.Panel types of quick freezing warehouse: color plastic steel plate, salted steel plate, embossed aluminum, etc.Haining,The exhaust temperature of the compressor in the fresh-keeping warehouse can be read out from the thermometer on the exhaust pipeline. It is related to the adiabatic index, the greater the compression ratio the higher the exhaust temperature, and vice versa.Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, with small density, light weight, strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.Heerenveen,Energy saving and power saving: the design cost of quick freezing warehouse mentioned above is very low, the selection of the thickness of the thermal insulation board should be appropriate, the tightness of the quick freezing warehouse door, and the temperature difference between the adjacent cold storage rooms should not be too large are all issues that we need to consider. There are also some tips, such as the use of air curtain machine on the quick freezing warehouse door. We remind users to use parallel units in quick freezing warehouse as far as possible and start them reasonably.When the cold storage is built, the diffusion of water vapor and the infiltration of air shall be prevented. When outdoor air invades, it will not only increase the cold consumption of the cold storage, but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore, it is necessary to set moisture-proof and heat insulation layer, professional cold storage installation, installation of cold storage,HainingDrug freezer, cold storage construction fruit fresh-keeping cold storage, medical cold storage and other products, which have a complete variety, sell well at home and abroad, and have a long service life! Products lead the wire industry. Welcome to inquire, so that the cold storage building has good sealing, moisture-proof and steam isolation performance.For cold storage, it is very common in our production and life. Cold storage is very important for food freezing and preservation, but its energy consumption is very large in the use of cold storage. How can we solve this problem?

Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.How to judge whether the controlled atmosphere storage is bad and the effect is poor? Under the same conditions the required temperature can be reached in minutes, but now it takes minutes. In this way, the refrigeration is obviously slow and the effect is poor, which will directly affect the use cost.. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room,During the use of the goods yard medical cold storage project, the distance between the goods and the goods must be cm. At the same time,HainingCold storage installation works, the distance between the goods and the cold fan should also be cm. No goods can be stored within this range, This is also an important content in the use of medical cold storage engineering.The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.

Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions when the water vapor with high indoor temperature migrates outdoors, it is impossible to condense in the wall due to the obstruction of the cold storage.Inspection standard,The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.Ammonia filling leak test: ammonia filling leak detection can be carried out after system blowdown and pressure leak test. The purpose is to improve the air tightness of the fresh-keeping warehouse system and lay a good foundation for the system to fill ammonia and wrap thermal insulation materials.Cold storage design step: the selection of cold storage refrigeration system the selection of cold storage refrigeration system is mainly the use of cold storage refrigeration compressor and air conditioning evaporator. Generally, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor, the price is relatively cost-effective; Small and medium-sized refrigerators are generally dominated by semi closed refrigeration compressors; Semi closed refrigeration compressor is adopted for large and medium-sized refrigerated warehouses. When adopting, ammonia refrigeration unit can also be considered. Because the output power of ammonia refrigeration unit is large and can be used for machine use, but the installation and management of refrigerated warehouses are cumbersome. When using the air-conditioning evaporator, the high-temperature cold storage uses the industrial cold fan as the air-conditioning evaporator. Its characteristic is that the temperature reduction speed is faster, but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots, which is characterized by very good temperature control effect and moderate cold storage.Haining,Installation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications and corresponding protection measures shall be taken for the installed equipment.The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example, the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage, it should be determined according to the type, quantity, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, the storage capacity of -kg per cubic meter can be referred to, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage medical cold storage quality assurance. During the preferential activities,HainingCold storage installation Designer, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.

Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse, the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame. - precautions for floor installation of cold storage: the floor shall be installed flat,MolarsWhich pharmaceutical cold storage has been installed, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).Molars,In case of fault alarm shutdown of the unit, first press the stop button of the unit (the alarm light will go out), and then the cause of the fault. It is not allowed to start the unit forcibly until the fault is eliminated.We should implement regular maintenance and daily maintenance, professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, large quantity, excellent quality and low price fire resistance - Waterproof - high temperature resistance, strong and durable, safe and reliable, and maintain the operation rate of the compressor.Birine,These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage, which makes people's retained items more convenient and reliable. With the continuous development of material technology, today's various cold storage materials emerge in endlessly, and the cold storage is different from each other. When purchasing, we should make reasonable comparison and select products suitable for our own use needs and economic conditions.The combined cold storage does not cool or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Whether frost is too thick on the evaporator in the warehouse. Check whether the refrigerant is leaking (apply soapy water to the pipeline connection, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct, and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.During the early operation of the refrigeration unit, carefully observe the oil return of the compressor and keep it clean. If it is found that the oil level is not clean enough or the oil level drops, replace it with new oil in time, so as to avoid bad compressor and reduce the service life of the compressor.

Core tip: in the cold storage project, only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure, convenient use and management and long service life.A new way.When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.Production department,Installation of cold storage, construction of cold storage, fruit preservation cold storage and medical cold storage have stable, safe, reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning so as not to damage the ground and affect the service life of the cold storage.Fire retardant, and it will decompose only at higher temperature. In addition, polyurethane forms carbon deposits on the surface of the foam, which helps to isolate the foam below. It can effectively prevent flame spread.The refrigerator compressor unit generally adopts high-end units with guaranteed quality and strong operation stability. The evaporator adopts the imported joint venture refrigeration air-cooled evaporator, which can effectively meet the refrigeration capacity of the refrigerator and ensure the refrigeration effect of the refrigerator. The refrigerator lamp adopts the special LED energy-saving lamp for the refrigerator, which has the advantages of low temperature resistance, low energy consumption and long service time, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.Energy costs,More and more people begin to build cold storage, and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.After startup, and see whether the condenser and cooling fan operate normally.Cold storage board, compressor, and other components in the cold storage can reasonably adjust the evaporation and condensation temperature,MolarsFresh storage installation Telephone, so as to improve the reduction of power consumption and reduce the production cost. Professional cold storage installation, installation of cold storage, cold storage construction fruit preservation cold storage, quality assurance, professional, timely supply and high cost performance. It has become the preferred brand for many wire products. Welcome to buy! Save more resources.Molars,Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time due to the saving of thermal insulation materials, such as the cooling room can be used as the cold storage room the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, the attic on the top floor can be built into the ice making room, etc.The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed,MolarsInstallation of fresh-keeping cold storage, the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.Preparation, prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model

There are many kinds of cold storage. According to the material it can be divided into color steel plate, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm without color requirements; The thickness of PE paint baking board is .mm, .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm, which is suitable for the thermal insulation conditions above ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = mm, heaven and earth plate width WB = mm, vertical angle plate W = mm, W = mm, W = mm and W = . The dimensions of non-standard plates are different from those of Wa, WB and W.In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (mm thick) has a very large span of M, and the polyurethane top storage plate (mm thick) has a span of m.Ranakan,After the refrigeration system is installed, it shall be beautiful and color.

The lower connecting piece shall be as close as possible to the lower side, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate, trim the plate edge, and then reinstall it to make the plate joint meet the requirements. When fixing the adapter, pay attention to fix the two parts of the adapter on the edges of the convex and concave library plates respectively, and fix them with rivets. The spacing of the adapter should be able to tension the two library plates. When wedging the wedge iron,RanakanInstallation of industrial cold storage, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time, and the wedge iron shall be fixed with rivets.Bhaktapur,Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall such as the sudden shower after a long time of exposure, or shading during exposure, will not cause damage to the surface of the cold storage.Features of quick freezing warehouse: the quick freezing technology is advanced, the frost free quick freezing method is adopted, and the automatic frost is adopted. The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the st century.

If there is more air or refrigerant oil in the evaporator, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, and the decline rate of warehouse temperature will be slowed down.The selection of wires shall have a safety factor, and the temperature of the wire surface shall not exceed ℃ during unit operation or defrosting.Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.Economic management,Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.The combined cold storage does not cool or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Whether frost is too thick on the evaporator in the warehouse. Check whether the refrigerant is leaking (apply soapy water to the pipeline connection, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct, and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.Airtight construction of quick freezing storehouse: the modified atmosphere fresh-keeping storehouse is developed on the basis of the traditional high-temperature fresh-keeping storehouse, which has the & ldquo; Refrigeration & rdquo; Function, long-term cold storage installation, cold storage installation, fruit fresh-keeping cold storage, medical cold storage, complete products, excellent quality and favorable price. There are also & ldquo; Air conditioning & rdquo; Function; However, the quick freezing storehouse is not a simple superposition of ordinary high temperature storehouse and air conditioning equipment. In order to adjust the gas composition in the storehouse quickly, it is necessary to ensure that the quick freezing storehouse has good air tightness. This has been confirmed by the theoretical research and a large number of practical experience of quick freezing warehouse.

The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically,RanakanFruit and vegetable fresh-keeping cold storage, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, according to the volume of ~ grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer, and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, which makes the vinegar absorb a lot of fish smell.Equipment maintenance,Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.The electrical equipment of the fresh-keeping warehouse equipment shall be prevented from moisture return to prevent it from being caused by power failure.Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.Ranakan,During installation, the plates shall be handled with care.
