70% to passWhich of the valves listed is normally closed when charging the refrigeration system through the high side?
ALiquid line king valve
BDehydrator inlet valve
CSuction line valve
DThermal expansion valve
AI Explanation
The correct answer is A) Liquid line king valve. When charging a refrigeration system through the high side, the liquid line king valve is normally closed. This allows the refrigerant to flow into the high-pressure side of the system, charging it with the necessary refrigerant. The other valves listed are not the correct choice - the dehydrator inlet valve, suction line valve, and thermal expansion valve serve different functions in the refrigeration system and are not involved in the charging process through the high side.
