Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/053740
Kind Code:
A1
Abstract:
A refrigeration cycle device comprising a compressor, a first flow path switching valve connected to the compressor, an outdoor heat exchanger connected to the first flow path switching valve, a first expansion valve connected to the outdoor heat exchanger, a flow straightener connected to the first expansion valve, a second flow path switching valve connected to the flow straightener, first and second indoor heat exchangers connected in series to the second flow path switching valve, and a second expansion valve located between the first and second indoor heat exchangers, wherein the first flow path switching valve is switched between a first condition in which refrigerant discharged from the compressor flows into the outdoor heat exchanger and a second condition in which refrigerant discharged from the compressor flows into the flow straightener, and the flow straightener allows refrigerant flowing from the flow straightener to the second flow path switching valve to flow in the same flow path both when the first flow path switching valve is in the first condition and the second condition, and allows refrigerant flowing from the second flow path switching valve to the flow straightener to flow in the same flow path both when the first flow path switching valve is in the first condition and the second condition.
