Document Type and Number:
WIPO Patent Application WO/2021/001869
Kind Code:
A1
Abstract:
This air conditioning device comprises a relay that has a first decompression device. The relay has a flow path switching valve that is provided to first refrigerant piping connected between a compressor and a load-side heat exchanger, and bypass piping that is connected to the flow path switching valve at one end, and at the other end is connected to second refrigerant piping connected between the first decompression device and a heat source-side heat exchanger. The flow path switching valve has, as internal flow paths, a first flow path communicating the first refrigerant piping and the bypass piping, and a second flow path communicating the compressor and the load-side heat exchanger via the first refrigerant piping, and switches the internal flow paths such that one internal flow path among the first flow path and the second flow path is open while the other internal flow path is closed.
