Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2022049423
Kind Code:
A
Abstract:
To improve the heat exchange efficiency of a heat-source side heat exchanger.SOLUTION: A refrigeration cycle device 1 comprises a refrigerant circuit 30 and a control part. The refrigerant circuit 30 sequentially connects a first compression element 11a, a second compression element 12a, a first heat-source side heat exchanger 211, a second heat-source side heat exchanger 212, a first heat-source side expansion mechanism 221, a second heat-source side expansion mechanism 222 and a use-side heat exchanger 111. In the refrigerant circuit 30, refrigerants flowing out of the first compression element 11a and the second compression element 12a are distributed to paths which are arranged in different rows of the first heat-source side heat exchanger 211 and the second heat-source side heat exchanger 212. In the refrigerant circuit 30, the first heat-source side expansion mechanism 221 and the second heat-source side expansion mechanism 222 are connected to the paths which are distributed with the refrigerants. The control part controls a condensation temperature of the refrigerant flowing in the windward path lower than a condensation temperature of the refrigerant flowing in the leeward path.SELECTED DRAWING: Figure 1
