FREEZING MACHINE USING WASTE HEAT OF CONDENSER

摘要

PURPOSE: A freezing machine using waste heat of condenser is provided to economically cut down freezing cost by using a waste heat occurring in a condenser as a driving energy of a compressor and freeze and keep cold where is no electric energy. CONSTITUTION: In a gas compressing type freezing circuit where a refrigerant reservoir(T), an evaporator(A), a condenser(C) and an expansion valve(V) is connected to a pipeline(Pl), a freezing machine using waste heat of condenser has many actuator compressors(P) parallel mounted on pipes between an evaporator(A) and a condenser(C). The compressors(P) do pump actions by expanded and contracted through temperature variations. The freezing machine using waste heat of condenser drives a freezing device by driving the actuator compressors(P) by using a waste heat of the condenser(C). Therefore, a freezing cost is economically cut down.
