Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/175359
Kind Code:
A1
Abstract:
This refrigeration cycle device is equipped with a refrigerant circuit which has a compressor (1), a cooling/heating switching mechanism (2), a condenser (3, 5), a refrigerant expansion mechanism (4), and an evaporator (3, 5). When the compressor (1) is in operation, the refrigerant expansion mechanism (4) opens the refrigerant circuit, a first three-way valve (11) connects the discharge portion (1b) of the compressor (1) to the condenser (3, 5), and a second three-way valve (12) connects the suction portion (1a) of the compressor (1) to the evaporator (3, 5). When the compressor (1) is stopped, the refrigerant expansion mechanism (4) closes the refrigerant circuit, the first three-way valve (11) connects the discharge portion (1b) of the compressor (1) to the evaporator (3, 5), and the second three-way valve (12) connects the suction portion (1a) of the compressor (1) to the evaporator (3, 5).
