Question 80Refrigeration & AC - Assistant Engineer

The correct answer is B) compressor. In a refrigeration system, the component labeled "A" in the illustration GS-RA-12 is the compressor. The compressor is the heart of the refrigeration system, responsible for circulating the refrigerant and maintaining the pressure differential necessary for the refrigeration cycle to function. It draws in the low-pressure, low-temperature refrigerant vapor from the evaporator and compresses it, increasing its pressure and temperature before sending it to the condenser. The other options are incorrect because: A) the accumulator is a different component that collects any excess liquid refrigerant; C) the condenser is the component where the high-pressure, high-temperature refrigerant vapor is cooled and condensed into a liquid; and D) the filter drier is a separate component that removes moisture and contaminants from the refrigerant.
