We all know that cold storage construction includes: insulation, electric control, temperature control, refrigeration equipment, pipes, valves, cold storage doors and other accessories. So the more important thing is the refrigeration equipment of the cold storage that plays a role in refrigeration, and there are many brands of refrigeration equipment compressors how to choose?

　　First of all, we need to know the size of the cold storage and the temperature of the cold storage. The cold storage equipment with different cooling capacity will be different.

　　Several common cold storages:

　　1. Constant temperature cold storage,storage temperature is 10-15℃, store products tropical fruits, sweet potatoes, etc.;(applicable to 60kw equipment)

　　2、Fresh-keeping cold storage,storage temperature is 0-5 ℃, store fruits, vegetables, food, medicine, etc.;(applicable to 60kw equipment)

　　3、Refrigerator,storage temperature at -5--18℃, storing ice cream, meat products, medicine, frozen food, etc.;(applicable to 60kw equipment)

　　4、Freezer,storage temperature is -18-25℃, seafood, food, meat products, medicinal materials, industry, etc.;(not applicable to 60kw equipment)

　　5、Quick-freezing warehouse,the storage temperature is -35-45℃, ultra-low temperature cold storage is generally used for glutinous rice balls, dumplings, zongzi, etc., and the freezing time is relatively short;(60kw equipment is not applicable)

The picture shows: the internal machine of the air cooler

　　The cold storage generally uses imported refrigeration equipment such as Bitzer and Copeland.The internal evaporator can use ceiling-mounted air coolers and piping.The air conditioning equipment is a special case, and the units are divided into many types.

　　1.Fully enclosed refrigeration compressor: The refrigeration capacity is less than 60KW, which is mostly used in air conditioners and small cold storage refrigeration equipment.

　　2.Semi-hermetic refrigeration compressor: The refrigeration capacity is 60-600KW, which can be used in various air-conditioning and cold storage refrigeration equipment.

　　3.Screw-type refrigeration compressor: refrigeration capacity 100 ~ 1200KW, can be used in large and medium-sized air conditioners, cold storage refrigeration equipment.
