Which of the following is responsible for transferring heat in refrigerants?

• A. Evaporation
• B. Condensation
• C. Convection
• D. Both evaporation and condensation

Answer: (D)

The process of transferring heat in refrigerants involves both evaporation and condensation. During evaporation, the refrigerant absorbs heat from the environment as it changes from a liquid to a gas. This heat absorption lowers the temperature of the surrounding area, allowing for cooling. Conversely, during condensation, the refrigerant releases heat as it changes from a gas back to a liquid. This heat release is often directed outside of the space being cooled, effectively removing heat from the indoor environment. The combination of these two processes is essential for the refrigeration cycle to function efficiently. Evaporation occurs in the evaporator coil, where the refrigerant absorbs heat, while condensation takes place in the condenser coil, where the refrigerant expels heat. The interplay between these phases allows for continuous heat transfer, making both processes vital in the overall operation of HVAC systems.
