The heat removed from the refrigerant by the condenser is

• A. Only sensible heat
• B. Only latent heat
• C. Both sensible and latent heat
• D. No heat is removed

Answer: (C)

In a condenser, the refrigerant goes from high-temperature vapor to liquid while rejecting heat to the surroundings. That heat rejection includes two parts: the sensible heat lost as the vapor cools from its inlet temperature down to the condensation (saturation) temperature, and the latent heat released as the vapor actually condenses into a liquid. If the liquid leaves subcooled, additional sensible heat is removed after condensation, but the essential idea is that both sensible and latent heat are rejected.
