Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/103599
Kind Code:
A1
Abstract:
A refrigeration cycle device that can selectively configure either a first refrigerant circuit for cooling, which causes a refrigerant to flow out through a liquid-phase refrigerant outlet (17c) of a vapor-liquid separator (17), or a second refrigerant circuit for heating, which causes a refrigerant to flow out through a vapor-phase refrigerant outlet (17b) of the vapor-liquid separator (17), wherein an oil separator (24) is provided in the refrigerant path from a radiator (12) to a first expansion valve (28). Thus, if the first refrigerant circuit is configured in the refrigeration cycle device (10), the refrigerant passing through the oil separator (24) is completely or mostly brought into the vapor phase, and the oil can be easily separated from the refrigerant. Furthermore, if the refrigerant is circulated in the first refrigerant circuit, the oil can also be stored in a place other than the vapor-liquid separator (17).
