ABSTRACT:
A centrifugal type separator is disposed on a downstream side of a temperature-operating type expansion valve. Liquid-phase refrigerant separated herein is again pressure-reduced by an aperture resistance and thereafter inducted to an inlet side of the evaporator by means of a liquid-phase refrigerant discharge passage. Meanwhile, gas-phase refrigerant separated by the separator is returned directly from a gas-phase refrigerant discharge passage to an evaporator outlet side passage, and after being united with superheated gas-phase refrigerant evaporated by the evaporator, is taken into a compressor. A temperature-sensing tube of the expansion valve is disposed further on the downstream side of the foregoing union location so as to enable the temperature of the superheated gas-phase refrigerant evaporated by the evaporator to be sensed accurately.
