How does the superheat setting affect the performance of a TEV?

The superheat setting directly affects the performance of a TEV by controlling the amount of refrigerant that enters the evaporator. If the superheat setting is too low, the TEV may not provide enough refrigerant, leading to reduced cooling capacity and efficiency. Conversely, if the superheat setting is too high, the TEV may allow too much refrigerant to enter the evaporator, resulting in increased energy consumption and potential system instability.
