Title:
冷凍サイクル装置およびそれを備えた空気調和装置
Document Type and Number:
Japanese Patent JP6888068
Kind Code:
B2
Abstract:
To provide a refrigeration cycle device and an air conditioner capable of enhancing heat transfer performance.SOLUTION: A compressor 5 and a heat exchanger group 10 are accommodated in an outdoor unit 4 of an outdoor device 3 of an air conditioner 1. The heat exchanger group 10 includes a first heat exchanger 11, a second heat exchanger 12 and a third heat exchanger 13. In a cooling operation, a refrigerant R discharged from the compressor 5 is branched into two refrigerants. One refrigerant R is sent to the second heat exchanger 12, and the other refrigerant R is sent to the third heat exchanger 13. In the second heat exchanger 12, heat exchange is performed so that the refrigerant R is converted to a two-phase refrigerant. In the third heat exchanger 13, heat exchange is performed so that the refrigerant R is converted to a two-phase refrigerant. The refrigerant R caused to flow in the second heat exchanger 12 and the refrigerant R caused to flow in the third heat exchanger 13 are merged with each other and then sent to the first heat exchanger 11. In the first heat exchanger 11, heat exchange is performed so that the two-phase refrigerant R is converted to a liquid refrigerant and then caused to flow in the first heat exchanger 11.SELECTED DRAWING: Figure 1
