Which component has the opposite function to the condenser?

Which component has the opposite function to the condenser?

• A. Evaporator
• B. Compressor
• C. Metering device
• D. Receiver

Answer: (A)

Heat transfer direction in a refrigeration cycle is what this question taps. The condenser removes heat from the refrigerant and changes it from vapor to liquid, releasing energy to the surroundings. The component that does the opposite—absorbing heat from the surroundings and turning the refrigerant from liquid into vapor—is the evaporator. That low-pressure, low-temperature side of the cycle is where the cooling effect happens, making it the opposite function of the condenser. The other parts—compressor, metering device, and receiver—have different roles (compressing, controlling flow, and storing liquid) and don’t perform the reverse heat-exchange action of the evaporator.
