Question 31Refrigeration & AC - QMED
70% to passWhen the relief valve opens on a refrigeration compressor discharge line, it discharges high-pressure refrigerant vapor to what location?
Aliquid strainer
Bsuction side of the compressor
Cinlet side of the evaporator
Drefrigerant inlet of the condenser
AI Explanation
The correct answer is B) suction side of the compressor. When the relief valve on a refrigeration compressor discharge line opens, it is designed to discharge the high-pressure refrigerant vapor back to the suction side of the compressor. This is done to protect the compressor and other components from excessive pressure buildup, which could potentially cause damage. The other answer choices are incorrect because the relief valve is not meant to discharge the refrigerant to the liquid strainer, the inlet side of the evaporator, or the refrigerant inlet of the condenser, as those locations are not the proper safeguard for the compressor.
