Which component moves refrigerant through the system?

Which component moves refrigerant through the system?

• A. Evaporator
• B. Condenser
• C. Metering Device
• D. Compressor

Answer: (D)

The component that moves refrigerant through the system is the compressor. It draws low‑pressure refrigerant vapor from the evaporator and compresses it into a high‑pressure, high‑temperature vapor. This creates the pressure difference that drives the refrigerant around the loop, pushing it from the evaporator to the condenser and back again. The other parts handle heat transfer and pressure changes, but they don’t actively pump the refrigerant through the system.
