Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To rapidly and effectively eliminate liquid-back to a compressor by introducing refrigerant discharged from the compressor into an accumulator when it is lowered to a predetermined temperature based on a temperature of the accumulator. SOLUTION: When evaporation of refrigerant in a cooler 8 is reduced, unevaporated liquid refrigerant of low temperature of a large quantity is introduced into an accumulator 9, a surface temperature of the accumulator 9 is hence lowered. When the temperature becomes, for example, 0 deg.C, a thermostat 13 opens a solenoid valve 12 based on an output of a temperature detector. Then, gas refrigerant of high temperature discharged from a compressor 2 is introduced into the accumulator 9 via an introducing tube 11. Thus, the temperature of the accumulator 9 is abruptly raised, and the liquid refrigerant therein is evaporated. Accordingly, discharge of the liquid refrigerant from a tube 9B is rapidly eliminated to prevent liquid-back to the compressor 2.
