70% to passIn a multi-evaporator refrigeration system, a solenoid valve is installed in the liquid line prior to what device?
Athe condenser
Bthe receiver
Cthe oil separator
Deach expansion valve
AI Explanation
The correct answer is D) each expansion valve. In a multi-evaporator refrigeration system, a solenoid valve is installed in the liquid line prior to each expansion valve. This allows the system to control the flow of refrigerant to each evaporator independently, which is necessary for proper operation in a multi-evaporator setup. The other answer choices are incorrect because: A) the condenser is not the proper location for a solenoid valve in the liquid line, B) the receiver is also not the correct location, and C) the oil separator is part of the compressor system, not the liquid line.
