The heat removed in a condenser consists of

• A. Sensible and latent heat
• B. Latent heat only
• C. Sensible heat only
• D. Mechanical heat

Answer: (A)

In a condenser, heat rejection comes from two parts: the latent heat of condensation and the sensible heat from cooling the refrigerant. The refrigerant enters as high-temperature vapor and must change to a liquid. The phase change releases latent heat, and as the vapor (and then the liquid) is cooled to the condenser outlet temperature, additional sensible heat is removed. If subcooling occurs, extra sensible heat is removed from the liquid after condensation. So the total heat rejected equals both latent and sensible components, making the correct understanding that the condenser removes sensible and latent heat. The other ideas miss one of these components or describe something not relevant to this process.
