Question 135Refrigeration & AC - 1st Asst/Chief

The correct answer is A) compressor. The compressor is the component in a refrigeration system labeled "A" in the illustration GS-RA-12. The compressor is the heart of the refrigeration cycle, as it circulates the refrigerant and provides the necessary pressure and temperature changes to enable the cooling process. The other options are incorrect because: B) the condenser is the component that condenses the refrigerant from a gas to a liquid, C) the accumulator collects any excess refrigerant in the system, and D) the filter drier removes any contaminants from the refrigerant.
