Question 75Refrigeration & AC - Assistant Engineer
70% to passMoisture is removed from a refrigeration system by what action?
Acutting in the dehydrator
Bcondensing the water in the heat exchanger
Cdraining refrigerant from the bottom of the condenser
Dopening a drain petcock on the oil separator
AI Explanation
You are correct, the answer is A) cutting in the dehydrator. The dehydrator or drier in a refrigeration system is responsible for removing moisture from the refrigerant. As the refrigerant circulates, any water vapor present is absorbed and trapped by the desiccant material inside the dehydrator. This prevents the buildup of water in the system, which could otherwise lead to corrosion and other issues. The other options are incorrect because: B) condensing water in the heat exchanger does not actively remove moisture, C) draining refrigerant from the condenser would not address moisture, and D) opening a drain on the oil separator would not target moisture removal.
