What happens to refrigerants during the evaporation process?

During the evaporation process, refrigerants absorb heat from their surroundings as they transition from a liquid state to a vapor state. This process is crucial in refrigeration and air conditioning systems, where the purpose is to remove heat from the environment, thus providing cooling. As the liquid refrigerant absorbs heat, its temperature rises, and it gains enough energy to overcome molecular forces, allowing it to evaporate and turn into vapor.

This heat absorption is essential for the cooling effect that these systems provide. The ability of the refrigerant to absorb a significant amount of heat during evaporation is a key characteristic that makes it effective for thermal management in various applications.
