Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/189805
Kind Code:
A1
Abstract:
This refrigeration cycle device (2) is provided with a flow passage switching section (162) and a control device (172). The flow passage switching section (162) is connected between an expansion valve (140) and a second heat exchanger (150). The flow passage switching section (162) is connected between the second heat exchanger (150) and a compressor (110). The control device (172) controls the flow passage switching section (162) to switch the direction of flow of a refrigerant flowing through the second heat exchanger (150) between a first flow direction and a second flow direction which is opposite the first flow direction. The flow passage switching section (162) includes a switching valve (40). The switching valve (40) has a motor, a valve body, and a plurality of valve ports (P41-P44). The motor is controlled by the control device (172). The valve body is moved by the motor. The state of communication between the plurality of valve ports (P41-P44) in the switching valve (40) is switched depending on the position of the valve body.
