Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/094148
Kind Code:
A1
Abstract:
An air conditioning device (301) is provided with a flow path switching valve (202). An outdoor heat exchanger (40) is divided into a first heat exchanger (40A) and a second heat exchanger (40B). A refrigerant supplied from an expansion valve (30) during a heating operation is divided into two flows and supplied to the first heat exchanger (40A) and the second heat exchanger (40B). The flow path switching valve (202) converges the refrigerant discharged from the first heat exchanger (40A) and the second heat exchanger (40B) and returns said refrigerant to a refrigerant inlet of a compressor (10) during the heating operation. A valve body (203) of the flow path switching valve (202) is configured so that during the heating operation, three ports (B1, B2, B3) communicate internally in a state of being isolated from another one port (A). The valve body (203) is configured so that during an operation to defrost the first heat exchanger (40A) or second heat exchanger (40B), two ports (A, B1 or A, B2) communicate internally and the other two ports (B2, C or B1, C) communicate internally.
