Refrigeration compressors are the heart of the refrigeration system, and most compressors today use hermetic reciprocating compressors. Bulite friji site na obere nrụgide ma na-ekesa friza na-aga n'ihu, sistemụ ahụ na-eme ka okpomọkụ dị n'ime usoro dị n'elu usoro okpomọkụ.

The low-pressure refrigerant liquid becomes low-pressure refrigerant vapor during the phase change in the evaporator, absorbing the surrounding heat during the phase change, thereby cooling the compressed air.
