Initial stage of cold storage equipmentCold storage has good water tightness. Polyurethane rigid foam has low water absorption, foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface and is not easy to permeate. It belongs to hydrophobic materials.Stabia Castle,System blowdown: it is easy to use the standby air compressor. When the air compressor cannot solve the problem, it can be replaced by ammonia compressor, but the exhaust temperature during use shall not exceed ℃, otherwise the oil viscosity will be reduced beyond the flash point and carbon will be formed, thus damaging parts and components.During the production of cold storage, the cold storage will produce fixed length, width and thickness according to the needs of various cold storage projects. Generally, cm thick cold storage plates are selected for high and medium temperature cold storage. The requirements for cold storage engineering plates of low-temperature storage and quick-frozen storage will be higher. Professional cold storage installation, installation construction, fruit fresh-keeping cold storage and medical cold storage ensure the quality,Stabia CastleCold storage large cold storage, Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. In this case, use cm or cm thick library board. When you budget the cold storage project, you can make a reservation according to the specific conditions of your cold storage temperature. If you don't make a reservation for the cold storage plate, you should pay attention to the density of the cold storage plate and the thickness of the steel plate when purchasing the cold storage plate. According to regulations, the foaming density of cold storage is per cubic meterKiiminki,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.In the low temperature environment, 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.Cold storage, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.

Goods are imported and exported frequently and the throughput is large according to the requirements of production and operationThe air-conditioned storage is relatively fast. It usually reaches the required temperature, a few minutes faster and an hour slower. Of course, according to the temperature of the environment, the amount of inventory and the temperature in winter and summer refrigeration is also divided into air cooling, water cooling, but most small refrigerators are air-cooled, The market share is about %.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, disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, and can monitor and record the temperature and humidity in the storage area.Convenient and efficient,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, which is mainly caused by excessive frost or excessive dust on the evaporator surface.With the increasing use of cold storage, cold storage board, as an important structure of cold storage,Stabia CastleInstallation of food quick freezing and 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.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.

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.Product line,However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.Vacuum test: after the pressure test of the fresh-keeping storehouse system is qualified, the vacuum leakage test of the fresh-keeping storehouse system can be carried out. The purpose is to improve the air tightness under the vacuum condition of the fresh-keeping warehouse and prepare the conditions for the ammonia filling of the fresh-keeping warehouse system.Fire retardant, flame retardant and high temperature resistant polyurethane is a kind of flame retardant self extinguishing material after adding flame retardant. Its softening point can reach more than ℃, and it will decompose only at higher temperature. In addition,The ultrasonic town is a patented technology with a shaped energy cover, which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?Various construction materials, such as material certificate, test report and stage acceptance record,Stabia CastleInstallation of small cold storage, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following points: a low-temperature hall, a closed platform, an electric sliding refrigerated door, an anti-collision flexible seal, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.
