Where is the expansion valve of Chery QQ3 located?

[LeGrace]

The expansion valve of Chery QQ3 is located at the interface of the air conditioning evaporator box. Introduction to Expansion Valve: The expansion valve is an important component in the refrigeration system, usually installed between the liquid storage cylinder and the evaporator. The expansion valve consists of three main parts: the valve body, the temperature sensing bulb, and the balance tube. Principle Introduction: The expansion valve allows the medium-temperature, high-pressure liquid refrigerant to pass through its throttling to become low-temperature, low-pressure wet steam. The refrigerant then absorbs heat in the evaporator to achieve the cooling effect. The expansion valve controls the valve flow rate based on the change in superheat at the end of the evaporator to prevent insufficient utilization of the evaporator area and knocking phenomena.
