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,Nai meihengFruit and vegetable cold storage installation company, 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.Precautions for purchase and shipment when using the medical cold storage project, the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees, the opening time must be strictly within minutes. If the temperature of the medical cold storage is left and right degrees, the opening time can not be too high, strictly within minutes.Nai meiheng, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room, the collection pit (pool) for flushing (thawing) and drainage should adopt the Countermeasures of avoiding freezing and cleaning and avoiding backflow of water.GalkissaCold 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,Nai meihengCold storage installation engineering enterprise, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor,Nai meihengInstallation and construction of cold storage, 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.

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.There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.Installation of box and operating device: the design of box shall be reasonable, and the appearance quality shall meet the requirements of beauty and practicality. All buttons, electrical switches, etc. shall be reliable, safe, long-term cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage medical cold storage, old brand, price advantage and quality guarantee! Easy to identify and operate. The indicator light shall be simple and clear. The device and each switch shall be installed on the upper side outside the warehouse door which is easy to operate, read data and not easy to be damaged, and shall be reliably fixed. The device box is installed on the door frame plate on the door opening side. The center line of the box overlaps the center line of the door frame plate. The bottom of the box is mm above the ground and is reliably fixed. The lighting lamp and door frame wire switch in the warehouse are installed directly below the device, and the height of the bottom edge of the switch box is about mm.

The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.Measure the power supply voltage according to the technical requirements for fluorine filling and commissioning of refrigeration system.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, the temperature system of the cold storage adopts microcomputer full-automatic, does not need special people to operate, and can be remotely controlled. When the temperature exceeds the specified range, it will automatically alarm, which is of great significance to the proper preservation of the cold storage.packing,Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.The factors affecting the installation cost of cold storage are as follows: cold storage construction: the site selection shall comply with laws and regulations and meet the relevant requirements for food hygiene and. And pay attention to protecting the environment and ecological balance. In addition, it shall be conducive to production, market prices continue to rebound' >

Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.Free consultation,The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.Because our large-scale fresh-keeping warehouse is generally composed of many thermal insulation boards, and the gap between each board is the place that needs maintenance. During construction, these gaps will generally be sealed with sealant, but if it is found that there are seal failure departments in the fresh-keeping warehouse during use, they need to be repaired in time.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, cold storage construction, 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.Nai meiheng,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.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, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.
