Question 84Refrigeration/AC - QMED70% to pass
The thermostat controlling the operation of the solenoid valve to a refrigerated box evaporator senses what temperature?
AI Explanation
The correct answer is B) the refrigerated box temperature.
The thermostat controlling the operation of the solenoid valve to a refrigerated box evaporator senses the temperature inside the refrigerated box, not the compressor discharge, evaporator coil inlet, or evaporator coil outlet temperatures. The thermostat is designed to maintain the desired temperature within the refrigerated box by opening and closing the solenoid valve to regulate the flow of refrigerant to the evaporator coil.
The other options are incorrect because they do not directly control the temperature of the refrigerated box. The compressor discharge temperature, evaporator coil inlet temperature, and evaporator coil outlet temperature are important for the overall refrigeration system, but the thermostat specifically monitors and regulates the temperature inside the refrigerated box.
