Q

To add refrigerant to the high side of an air conditioning system, you should close the king valve and introduce the refrigerant through what valve in what state?

🔍 Key Concepts

• Understand the difference between the high side and low side of a refrigeration/AC system • Know which valves connect to the liquid line versus the suction (vapor) line • Know in what state (liquid or vapor) refrigerant is normally added to the high side for safety and equipment protection

💭 Think About

• Which part of the system (discharge, condenser, liquid line, suction) is considered the high side during normal operation? • If you introduce liquid refrigerant into the wrong side of the system, what component could you damage? • Which of the listed valves is normally used for charging versus for purging or service only?

✅ Before You Answer

• Confirm which valves are actually connected to the high-side liquid line or discharge line • Verify whether suction service valves are on the low-pressure side of the compressor • Check standard practice: high-side charging is typically done with liquid refrigerant at a point where it will not enter the compressor directly as a slug of liquid
