Title:
REVERSING VALVE AND HEAT EXCHANGE SYSTEM HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2023/046180
Kind Code:
A1
Abstract:
Provided in the present application are a reversing valve and a heat exchange system having same. The reversing valve comprises: a valve seat, having a first flow channel, a second flow channel, a third flow channel and a fourth flow channel, the first flow channel having an inlet, and the second flow channel having an outlet; a first valve body, controlling connection and disconnection of the first flow channel and the third flow channel; a second valve body, controlling connection and disconnection of the first flow channel and the fourth flow channel; a third valve body, controlling connection and disconnection of the third flow channel and the second flow channel; and a fourth valve body, controlling connection and disconnection of the fourth flow channel and the second flow channel. When the reversing valve is in a first operating state, the second valve body controls the first flow channel to communicate with the fourth flow channel such that a refrigerant flows out from the fourth flow channel, and the third valve body controls the third flow channel to communicate with the second flow channel such that the refrigerant flows back to the third flow channel and is discharged; and when the reversing valve is in a second operating state, the first valve body controls the first flow channel to communicate with the third flow channel such that the refrigerant flows out from the third flow channel, and the fourth valve body controls the fourth flow channel to communicate with the second flow channel such that the refrigerant flows back to the fourth flow channel and is discharged. According to the present application, the problem in the prior art of a four-way valve being prone to leaking refrigerant is solved.
