Which component rejects both sensible and latent heat from the refrigeration system?

Which component rejects both sensible and latent heat from the refrigeration system?

• A. Evaporator
• B. Compressor
• C. Expansion valve
• D. Condenser

Answer: (D)

Condenser. In a vapor-compression refrigeration cycle, the condenser is the heat-rejecting component. After the refrigerant is compressed, it becomes high‑temperature, high‑pressure vapor. The condenser transfers heat from that vapor to the surroundings, causing the refrigerant to condense into a liquid. This process releases latent heat during condensation, and as the liquid cools toward ambient temperature, it also sheds sensible heat. So the condenser handles both forms of heat removal. The evaporator absorbs heat from the space (not rejects it), the expansion valve only reduces pressure (cooling the refrigerant as it expands), and the compressor increases temperature and pressure but does not reject heat by itself.
