Refrigerating system has ejector that ejects part of refrigerant fed from bypass pipes and evaporator back to compressor based on venturi principle so as to compensate for reduced energy of compressor

摘要

An ejector (27) connected to the bypass pipes (17a,17b) and the evaporator (26) is used for ejecting the part of the refrigerant fed from the bypass pipes and the evaporator back to the compressor (10) based on a venturi principle so as to compensate for reduced energy of compressor. The pipes are operated under the control of the magnet valves which are connected to compressor output portion.
