Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/234868
Kind Code:
A1
Abstract:
This refrigeration cycle device (1) comprises a refrigerant circuit (RC), a first refrigerant, and a second refrigerant. The refrigerant circuit (RC) has a first region (R1), a second region (R2), a first valve (161), a second valve (162), and a third valve (163). The first region (R1) can encapsulate the first refrigerant. The second region (R2) can encapsulate the second refrigerant. The first valve (161) is disposed between an indoor unit (10) and the first region (R1). The second valve (162) is disposed between the indoor unit (10) and the second region (R2). The third valve (163) is disposed between the first region (R1) and the second region (R2). The first valve (161), the second valve (162), and the third valve (163) are each configured to be capable of opening/closing the refrigerant circuit (RC). The first refrigerant is different from the second refrigerant. The second refrigerant is a natural refrigerant.
