摘要： A refrigerating apparatus including a first compressor, a condenser, a first pressure reducer a first evaporator, a second pressure reducer and a second evaporator connected together by lines to form a refrigerating circuit for a refrigerant to flow therethrough, wherein a second compressor is connected at its suction side to the second pressure reducer for receiving gaseous component of refrigerant from the first evaporator and connected at its discharge side to the line between the first compressor and the condenser. An evaporative pressure control valve may be mounted in the line between the first evaporator and the second pressure reducer or the line between the second pressure reducer and the second evaporator. A bypass line mounting an electromagnetic valve may connect the line between the first evaporator and the second pressure reducer to the line between the second pressure reducer and the second evaporator.
