When the relief valve opens on a refrigeration compressor discharge line, it discharges high-pressure refrigerant vapor to what location?
AI Explanation
The correct answer is A) suction side of the compressor.
When the relief valve opens on a refrigeration compressor discharge line, it discharges the high-pressure refrigerant vapor back to the suction side of the compressor. This is done to prevent the discharge pressure from exceeding the safe operating limits of the system, which could damage the compressor or other components.
The other options are incorrect because: B) the evaporator inlet would not be the correct location for the relief valve discharge, C) the condenser inlet would not be the correct location either, and D) the liquid strainer is not the appropriate place for the relief valve discharge.
