Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059054
Kind Code:
A1
Abstract:
This refrigeration cycle device has an indoor unit, a first outdoor unit, a second outdoor unit, and a control unit. The indoor unit has an indoor heat exchanger. The first outdoor unit and the second outdoor unit are connected in parallel with the indoor unit. The second outdoor unit has a compressor, an outdoor heat exchanger, and a four-way valve. The four-way valve switches between supplying the refrigerant discharged from the compressor to the indoor heat exchanger and the outdoor heat exchangers. The four-way valve has a main valve having a main valve body, and an auxiliary valve having an auxiliary valve body. The main valve body can move between a first position and a second position. In the first position, the refrigerant discharged from the compressor is supplied to one of the indoor heat exchanger and the outdoor heat exchangers. In the second position, the refrigerant discharged from the compressor is supplied to the other of the indoor heat exchanger and the outdoor heat exchangers. The auxiliary valve body is driven by a solenoid and can move between a third position and a fourth position. In the third position, the main valve body is arranged in the first position. In the fourth position, the main valve body is arranged in the second position. In the case that the first outdoor unit is operated and the second outdoor unit is stopped, if the main valve body is not in the first position, then, after the auxiliary valve body has been arranged in the fourth position, the control unit moves the auxiliary valve body to the third position.
