Question 60Refrigeration & AC - 1st Asst/Chief
70% to passIf 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?
Ahigh superheat in the outlet coil
Brefrigerant slugs in the receiver
Clow suction pressure
Dnoisy compressor operation upon starting
AI Explanation
The correct answer is D) noisy compressor operation upon starting. When the liquid-line solenoid valve is leaking during the 'off' cycle, it allows refrigerant to continue flowing back to the compressor. This can lead to refrigerant slugs or liquid refrigerant entering the compressor upon startup, causing noisy and potentially damaging operation. The other options are incorrect because: A) High superheat in the outlet coil would not be caused by a leaking liquid-line solenoid valve. B) Refrigerant slugs in the receiver would not be the primary issue with a leaking liquid-line solenoid valve. C) Low suction pressure would not be the direct result of a leaking liquid-line solenoid valve.
