We all know that cold storage construction includes: insulation, electric control, temperature control, refrigeration equipment, pipes, valves, cold storage doors and other accessories. So it is more important to play the role of refrigeration refrigeration equipment, and refrigeration equipment compressor brand there are many kinds of how to choose?

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

Several common cold storage:

1, constant temperature cold storage, storage temperature at 10-15℃, storage products tropical fruits, sweet potatoes, etc.; (Suitable for 60kw equipment)

2, fresh cold storage, storage temperature at 0--5℃, storage of fruits, vegetables, food, medicine, etc.; (Suitable for 60kw equipment)

3, cold storage, storage temperature at -5--18℃, store ice cream, meat products, medicine, frozen food, etc.; (Suitable for 60kw equipment)

4, freezer, storage temperature of -18-25℃, seafood, food, meat products, medicinal materials, industry, etc.; (Not applicable to 60kw equipment)

5, frozen warehouse, storage temperature at -35--45℃, ultra-low temperature cold storage is generally used for dumplings, dumplings, zongzi, etc., the need for freezing time is shorter; (Not applicable to 60kw equipment)

Cold storage generally adopts imported refrigeration equipment such as Bitzer and valley wheel, the evaporator can use the suspended ceiling type cooler and the row pipe, the air conditioning equipment is a special case, and the unit is divided into many types.

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

2. Semi-closed refrigeration compressor: refrigerating capacity 60 ~ 600KW, can be used in various air conditioning, cold storage refrigeration equipment.

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