🔍 Key Concepts

• High-side vs low-side charging in a refrigeration system • Normal flow path of refrigerant through king valve, dehydrator, and TXV • Which valves must remain open to allow proper refrigerant flow and dehydration when charging

💭 Think About

• Trace the normal direction of refrigerant flow from the receiver toward the evaporator and ask: which components must refrigerant pass through during charging? • Consider which valve, if left open, would prevent proper control of refrigerant into the evaporator and could risk liquid floodback to the compressor. • Think about which component is a metering device and whether you would normally shut it by a hand valve during charging.

✅ Before You Answer

• Identify which valve directly controls flow into the evaporator (metering device). • Confirm which valve isolates the receiver/liquid line from the rest of the system when closed. • Verify which component (dehydrator vs TXV vs king valve vs suction valve) you would NOT normally throttle or shut solely for charging on the high side.
