Which component increases the refrigerant pressure?

Which component increases the refrigerant pressure?

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

Answer: (D)

The compressor is the component that increases refrigerant pressure. It takes low‑pressure, low‑temperature vapor from the evaporator and compresses it, raising both pressure and temperature. The high‑pressure, high‑temperature gas then moves to the condenser to release heat and condense into a liquid. By contrast, the evaporator operates at low pressure to absorb heat, and the metering device lowers the pressure of the liquid refrigerant before it enters the evaporator. This clarifies why the compressor is the part responsible for boosting pressure.
