Question 110Refrigeration/AC - QMED70% to pass
If a refrigeration system, equipped with a reciprocating compressor, has a liquid line solenoid valve that is leaking during the 'off' cycle, what would this cause?
AI Explanation
The correct answer is D) noisy compressor operation upon starting.
The leaking liquid line solenoid valve during the 'off' cycle would allow refrigerant to continue flowing to the compressor, even when the system is not running. This refrigerant flood-back to the compressor can lead to liquid refrigerant entering the compressor, causing a noisy and potentially damaging start-up.
The other options are incorrect because:
A) Refrigerant slugs in the receiver would not be a direct result of the leaking liquid line solenoid valve.
B) Low suction pressure is more likely to be caused by an issue with the evaporator, not the leaking valve.
C) High superheat in the outlet coil is not a direct consequence of the leaking valve.
