Abstract

PURPOSE: To provide easy control of the evaporative pressure of a refrigerating device, by fitting evaporators in parallel between a liquid receiver and a compressor, with a variable throttle upstream the largest evaporator and fixed throttles upstream other evaporators being in series respecrively.
CONSTITUTION: When the heat loados No.1 and No.2 evaporators 18, 23 decreases and the outlet pressure of No.1 evaporator 18 drops, an evaporative pressure control vave 47 starts controlling the pressure so that the opening degree of a discharge temperture control valve 24 for No.2 evaporator circuit 25 becomes small. The flow of refrigerant flowing in the circuit 25 having a capillary tube 46 is then equal to that at the time of high load operation. The pressure control is therefore easy for the discharge temperature control valve 24, and since th refrigerant flowing througth No.1 and No.2 evaporative circuits 20, 25 flows in the evaporative pressure control valve 47, the flow is large in quantity and easy to control its evaporative pressure
