Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/075897
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device that comprises: a cooling expansion valve (19); a bypass channel (22) that allows a restricting channel (66) of the cooling expansion value (19) to be bypassed and through which a coolant is made to flow; and a check valve (23) that opens/closes the bypass channel (22). The check valve (23) allows coolant flow therethrough from a temperature control heat exchanger (18) side of the bypass channel (22) toward the opposite side, and prevents coolant flow therethrough in the opposite direction. At the time of cooling a target of temperature control, a switching device switches to a cooling coolant flow path in which the coolant sequentially flows through the restricting channel (66) of the cooling expansion valve (19), the temperature control heat exchanger (18), and a return channel (63) of the cooling expansion valve (19). At the time of heating the target of temperature control, the switching device switches to a heating coolant flow path in which the coolant flows through the bypass channel (22), the temperature control heat exchanger (18), and the return channel (63) of the cooling expansion valve (19).
