Question 56Refrigeration & AC - Assistant Engineer

The correct answer is B) 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 individual evaporators, and it is most effective when placed after the receiver, which collects the liquid refrigerant from the condenser. Placing the king solenoid valve in this location allows it to regulate the flow of refrigerant to the evaporators as needed, rather than before the condenser or between the condenser and receiver, where it would not be as effective in controlling the refrigerant flow.
