Question 18Refrigeration/AC - QMED70% to pass
Moisture is removed from recovered refrigerant using a recycling machine by what means?
AI Explanation
The correct answer is D) circulating the refrigerant through a dehydrator.
In a recycling machine, the refrigerant is circulated through a dehydrator, which removes moisture from the refrigerant. The dehydrator contains a desiccant material that absorbs and traps the moisture, drying out the refrigerant before it is stored or reused. This is the primary method used to remove moisture from recovered refrigerant in a recycling machine.
The other options are incorrect because: A) purging non-condensables does not directly remove moisture, B) opening a drain petcock on the oil separator would not remove moisture from the refrigerant, and C) condensing the moisture in the condenser is not the primary means of moisture removal in a recycling machine.
