ABSTRACT:
An ejector cycle device includes a gas-liquid separator for separating a refrigerant flowing out of an ejector into gas-phase refrigerant and liquid-phase refrigerant. The gas-liquid separator further separates refrigeration oil from the refrigerant. The refrigeration oil used by the ejector cycle device is less compatible to the refrigerant on the low-pressure side than the compatibility of the refrigeration oil with the refrigerant on a high-pressure side.
