Question 93Refrigeration/AC - 1st Asst/Chief70% to pass
In a large refrigeration system having more than one evaporator, a king solenoid valve should be installed in what location?
AI Explanation
The correct answer is D) just after the receiver.
In a large refrigeration system with multiple evaporators, a king solenoid valve should be installed just after the receiver. This is because the king solenoid valve is used to control the flow of refrigerant to the various evaporators, and it is best placed after the receiver to ensure that the refrigerant is in a liquid state before it enters the valve.
The other options are incorrect because: A) before the condenser would be too early in the system, B) between the condenser and receiver would be redundant, and C) before the back pressure regulating valve would be too late in the system, as the king solenoid valve needs to control the flow to the evaporators.
