Which component serves as a pump, circulating refrigerant through tubing that connects indoor and outdoor components?

• A. Condenser
• B. Compressor
• C. Metering devices
• D. Diffusers

Answer: (B)

In a refrigerant loop, the pump-like element that drives circulation is the compressor. It takes in low-pressure vapor from the evaporator, compresses it to high-pressure high-temperature vapor, and pushes it into the outdoor condenser. This creates the pressure differential that moves refrigerant through the tubing that connects the indoor and outdoor components, keeping the cycle moving. After heat is rejected in the condenser and the refrigerant becomes a high-pressure liquid, it passes through a metering device that controls flow, then into the evaporator to absorb heat again. The condenser’s job is heat rejection, not pumping; the metering device regulates flow but doesn’t circulate, and diffusers are for distributing conditioned air, not circulating refrigerant.
