70% to passWhich of the valves listed is normally closed when charging the refrigeration system through the high side?
AThermal expansion valve
BSuction line valve
CLiquid line king valve
DDehydrator inlet valve
AI Explanation
The correct answer is C) Liquid line king valve. When charging a refrigeration system through the high side, the liquid line king valve is normally closed. This valve controls the flow of liquid refrigerant from the condenser to the rest of the system. Keeping this valve closed allows the refrigerant to be pushed into the high side of the system, charging it properly. The other valves listed are not the typical point of entry for charging the system.
