摘要： PROBLEM TO BE SOLVED: To actualize simple construction for change-over between a high temperature side and a low temperature side, to thereby improve mountability while holding down cost.
SOLUTION: High pressure refrigerant discharged from a compressor 10 is selectively distributed to the inlet side or to the discharge port side of an ejector 30 via a four-way valve 60. When the high pressure refrigerant discharged from the compressor 10 is distributed to the discharge port side, the ejector 30 is functioned as a passage like a mere pipe in which the refrigerant flows. This actualizes simple construction for change-over between the high temperature side and the low temperature side, thereby improving mountability while holding down cost.
