Question 92Refrigeration/AC - QMED70% to pass
In a multi-evaporator refrigeration system, a solenoid valve is installed in the liquid line prior to what device?
AI Explanation
The correct answer is D) each expansion valve.
In a multi-evaporator refrigeration system, a solenoid valve is typically installed in the liquid line prior to each expansion valve. This is done to control the flow of liquid refrigerant to the individual evaporators and to prevent refrigerant migration during the off-cycle.
The other options are incorrect because:
A) The condenser is located on the high-pressure side of the system, while the solenoid valve is installed on the low-pressure liquid line.
B) The oil separator is used to remove oil from the refrigerant, and is not directly related to the placement of the solenoid valve.
C) The receiver is a storage vessel for liquid refrigerant, and is not the appropriate location for the solenoid valve.
