Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/216861
Kind Code:
A1
Abstract:
The air conditioner (1) comprises a bypass flow path (161) and a cooling/heating switching mechanism (150). The bypass flow path (161) is configured so as to serve as at least part of the flow path for connecting a third port (P3) to the refrigerant inlet (10a) of a compressor. A second expansion valve (110) opens and closes the bypass flow path (161). The cooling/heating switching mechanism (150) includes check valves (103, 104) and four-way valves (102, 101). The four-way valve (102) causes the refrigerant outlet of the check valve (103) to communicate with one of the refrigerant inlet (10a) and the refrigerant outlet (10b) of the compressor. The four-way valve (101) causes the refrigerant inlet of the check valve (104) to communicate with one of the refrigerant inlet (10a) and the refrigerant outlet (10b) of the compressor (10), and causes a port (P4) to communicate with the other.
