Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059136
Kind Code:
A1
Abstract:
This refrigeration cycle device (11) comprises a refrigerant circuit (20) configured to circulate a refrigerant, and a control device (100) which controls the refrigerant circuit (20). The refrigerant circuit (20) includes a compressor (1), a first heat exchanger (2), a first expansion device (3), a second expansion device (8), a third expansion device (9), a second heat exchanger (4), and a cooling unit (6) which cools a substrate of the control device (100). In a first path of the refrigerant circuit (20), the compressor (1), the first heat exchanger (2), the first expansion device (3), the second expansion device (8), and the second heat exchanger (4) are connected in order. In a second path of the refrigerant circuit (20), the cooling unit (6) and the third expansion device (9) are connected in order from a first point (5) between the first expansion device (3) and the second expansion device (8) to a second point (7) between the compressor (1) and the second heat exchanger (4).
