Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/124458
Kind Code:
A1
Abstract:
This refrigeration cycle device (100) is provided with: a compressor (1), a first outdoor heat exchanger (4), and a second outdoor heat exchanger (5) that are connected to a refrigerant expanding mechanism (8) and an indoor heat exchanger (9), and constitute a refrigerant circuit; and a flow path switching mechanism (20) that is connected between the compressor (1), the first outdoor heat exchanger (4), the second outdoor heat exchanger (5), and the indoor heat exchanger (9) in the refrigerant circuit, and switches the circulation direction in the refrigerant circuit of a refrigerant compressed by the compressor (1). The first outdoor heat exchanger (4) and the second outdoor heat exchanger (5) in the refrigerant circuit are disposed so that the refrigerant flows in parallel. The refrigeration cycle device (100) is further provided with a flow rate adjusting mechanism (7) for adjusting the amount of refrigerant flowing through the second outdoor heat exchanger (5). When switching between a cooling operation and a heating operation, the circulation direction of the refrigerant is switched by the flow path switching mechanism (20) while the refrigerant flow path to the second outdoor heat exchanger (5) is temporarily closed by the flow rate adjusting mechanism (7).
