Where is the thermostatic expansion valve typically mounted?

The thermostatic expansion valve is typically mounted at the inlet of the evaporator. This location is crucial because the valve's primary function is to control the flow of refrigerant into the evaporator, ensuring that the evaporator coil operates efficiently and effectively. When positioned at the inlet, the thermostatic expansion valve responds to the temperature and pressure of the refrigerant, allowing it to adjust the flow based on the cooling demand of the system.

By controlling the amount of refrigerant entering the evaporator, the valve helps to maintain the desired temperature and pressure conditions necessary for optimal heat absorption. This contributes to the overall efficiency of the refrigeration cycle, as proper refrigerant flow prevents issues such as flooding or starvation of the evaporator, which could lead to reduced cooling capacity or system failure.Thus, positioning the thermostatic expansion valve at the inlet is essential for the system's effective operation and performance.
