Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/137510
Kind Code:
A1
Abstract:
The present disclosure obtains a refrigeration cycle device in which refrigerant deficiencies occurring when a refrigerant circulation circuit is switched are suppressed. A refrigeration cycle device according to one embodiment of the present disclosure comprises a compressor 1, a heat-source-side heat exchanger 2, a first usage-side heat exchanger 21, a second usage-side heat exchanger 31, and a flow path switching device. The flow path switching device switches between: a first refrigerant circulation circuit, which includes the second usage-side heat exchanger 31, and in which the second usage-side heat exchanger 31 functions as either an evaporator or a condenser; and a second refrigerant circulation circuit, which includes the heat-source-side heat exchanger 2 and the first usage-side heat exchanger 21 but does not include the second usage-side heat exchanger 31, and in which either the heat-source-side heat exchanger 2 or the first usage-side heat exchanger 21 functions as an evaporator. When the second refrigerant circulation circuit is formed, the second usage-side heat exchanger 31 communicates with a flow path between the heat-source-side heat exchanger 2 and the compressor, and also communicates with a flow path between the compressor 1 and the heat exchanger functioning as the evaporator of the second refrigerant circulation circuit.
