Q

In a large refrigeration system having more than one evaporator, a king solenoid valve should be installed in what location?

🔍 Key Concepts

• King solenoid valve purpose and normal location in a multi‑evaporator system • Flow path of refrigerant: condenser → receiver → liquid line → expansion controls → evaporators • Difference between liquid‑line isolation and evaporator/back‑pressure control devices

💭 Think About

• Trace the flow of liquid refrigerant from the condenser outlet all the way to the evaporators. At what point would a single valve be able to stop liquid flow to ALL evaporators? • Think about what a king valve must protect: is it meant to isolate the condenser, the receiver, or the evaporators for pump‑down and service? • Which answer choice locations see subcooled liquid from the receiver versus locations that are on the high‑side versus low‑side of the system?

✅ Before You Answer

• Be sure the location you pick is on the liquid line feeding all evaporators, not just one branch. • Confirm that the valve position you choose would allow pumping down the entire evaporator side of the system into the condenser/receiver. • Eliminate any option that is clearly on the wrong side of the system (for example, on the discharge line or clearly within just one evaporator’s branch**).
