The selection of refrigeration system in cold storage is mainly the selection of refrigeration compressor and refrigeration evaporator. In general, medium and small cold storages mainly use fully enclosed compressors and semi enclosed compressors. Due to the small power of totally enclosed and semi enclosed compressors, the price is relatively cheap; Freon is generally selected as refrigerant. When selecting the evaporator, the high temperature cold storage uses the air cooler as the evaporator, which is characterized by fast cooling speed, but easy to cause the water loss of the cold storage; The medium and low temperature cold storage mainly adopts the evaporation exhaust pipe and air cooler made of aluminum tube.
