AI Technical Summary
Technical Problem
The control valves in the air conditioning system are making excessive noise due to the presence of both gas and liquid refrigerant, which affects user comfort.
Method used
The connector is made of stainless steel and copper alloy and has a variable diameter section to gradually reduce the inner diameter. The throttling effect of the variable diameter section allows for more complete mixing of gas and liquid refrigerant, reduces the amount of air bubbles entering the control valve body, and lowers noise.
Benefits of technology
It effectively suppresses control valve noise, improves the comfort of air conditioning system use, reduces refrigerant transmission pressure loss, and lowers energy consumption.

Abstract
The application provides a control valve assembly and an air conditioner. The control valve assembly comprises a control valve including a valve body, a first connecting pipe made of stainless steel, the first connecting pipe having a first inlet end and a first outlet end, and a second connecting pipe made of a material mainly containing copper, the second connecting pipe having a second inlet end and a second outlet end, the first outlet end being welded to the second inlet end, and the second outlet end being welded to the valve body. At least one of the first connecting pipe and the second connecting pipe is provided with at least one reducing section, and the inner diameter of the reducing section gradually decreases in the direction from the first connecting pipe to the valve body. When the gas-liquid coexisting refrigerant enters the reducing section, the reducing section throttles the refrigerant, so that the two-phase refrigerant in the reducing section is more fully fused, thereby inhibiting the generation of bubbles, and thus the noise during the operation of the control valve is reduced.
