Document Type and Number:
WIPO Patent Application WO/2023/058447
Kind Code:
A1
Abstract:
[Problem] To provide a valve device capable of suppressing leakage of a refrigerant, a decrease in cooling efficiency, and noise caused by a flow of the refrigerant. [Solution] A valve device 5 is used in an air conditioning apparatus 1. The valve device 5 has: one valve body 100 having a plurality of refrigerant passages; and a plurality of valve units mounted to the valve body 100. The plurality of refrigerant passages include: a high-temperature refrigerant passage in which a high-temperature refrigerant flows; an intermediate-temperature refrigerant passage in which an intermediate-temperature refrigerant, the temperature of which is lower than that of the high-temperature refrigerant, flows; and a low-temperature refrigerant passage in which a low-temperature refrigerant, the temperature of which is lower than that of the intermediate-temperature refrigerant, flows.
