Question 83Refrigeration/AC - QMED70% to pass
A box solenoid valve used in a refrigeration system should be installed in what manner?
AI Explanation
The correct answer is C) upright, controlled by a thermostat sensing the temperature of the box, and upstream of the thermal expansion valve.
This is the correct answer because the box solenoid valve should be installed upright to ensure proper operation and prevent issues like air pockets or liquid slugging. It should be controlled by a thermostat sensing the temperature of the box, as this allows the valve to open and close based on the cooling demand. Additionally, the box solenoid valve should be installed upstream of the thermal expansion valve to regulate the flow of refrigerant into the evaporator.
The other options are incorrect because option A places the valve downstream of the thermal expansion valve, which is not the proper location. Options B and D have the valve orientation or control method incorrect compared to industry standards and best practices.
