Question 183Refrigeration & AC - Assistant Engineer
70% to passBesides the evaporator pressure, the thermal expansion valve reacts directly to changes in what parameter?
Apressure drop across the evaporator coils
Bliquid refrigerant pressure at the solenoid valve
Ctemperature of the evaporator coil outlet
Dtemperature of the space being cooled
AI Explanation
The correct answer is C) temperature of the evaporator coil outlet. The thermal expansion valve reacts directly to changes in the temperature of the refrigerant leaving the evaporator coil. As the temperature of the refrigerant increases, the thermal expansion valve opens more to allow more refrigerant flow, which helps maintain the desired temperature in the space being cooled. The other options are not directly related to the operation of the thermal expansion valve.
