Where is the expansion valve of the Besturn B90 located?

The air conditioning expansion valve is located downstream of the dryer and upstream of the evaporator, with the installation position likely beneath the dashboard. Introduction to the expansion valve: The expansion valve is one of the four major components of a refrigeration system. It serves as a critical device for regulating and controlling the flow and pressure of refrigerant entering the evaporator, and also acts as the "dividing line" between the high and low-pressure sides. Characteristics of the refrigeration system: The expansion valve features an advanced dual-flow balanced orifice structure. By utilizing a bi-directional thermal expansion valve, the refrigeration system reduces the number of required components such as expansion valves, check valves, and solenoid valves. The expansion valve maintains stable superheat, ensuring consistent system operation.
