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 B) each expansion valve.
In a multi-evaporator refrigeration system, a solenoid valve is installed in the liquid line prior to each expansion valve. This is done to control the flow of refrigerant to each evaporator and prevent refrigerant migration when the compressor is off. The solenoid valve opens and closes based on the thermostat signal, allowing refrigerant to flow to the corresponding expansion valve and evaporator.
The other options are incorrect because: A) the receiver is not the device that requires a solenoid valve prior to it, C) the oil separator is not the relevant component, and D) the condenser is located on the high-pressure side of the system, not the liquid line.
