Abstract

PURPOSE: To prevent the pressure of refrigerant gas to be discharged from a compressor from excessively rising by feeding a part of the gas discharged from the compressor to a condenser when the pressure of the gas discharged from the compressor exceeds a predetermined value, dissipating heat from the condenser, and then introducing the residue into an evaporator.
CONSTITUTION: A pressure switch 40 for sensing the pressure of refrigerant gas discharged from a compressor 1 is provided in a discharge tube 1a of the compressor 1. When the pressure sensed by the switch 40 is a predetermined value or less, a solenoid valve 2 remains closed, while when it exceeds the value, the valve 2 is opened. Then the pressure of the gas discharged from the compressor 1 is lower than a predetermined value, i.e., a pressure set by the switch 40, under a state where a load is cooled by a first evaporator 8 and heated by a second evaporator 11, solenoid valves 6, 18, 20 are opened, and the valves 2, 9, 17, 21 are closed. Thus, the gas of high temperature and high pressure discharged from the compressor 1 is introduced to the evaporator 1 through a bypass tube 31 and the valve 18 to heat the load in the step of passing the evaporator 11 to be condensed and liquefied.
