The cooling effect in a refrigeration system is primarily achieved through the process of evaporation. In this phase, a refrigerant absorbs heat from its surroundings as it transitions from a liquid state to a vapor state. This absorption of heat is essential because it enables the refrigeration system to lower the temperature of the area or substance being cooled.

During evaporation, the refrigerant at low pressure enters the evaporator coil, where it absorbs heat from the environment, causing the refrigerant to evaporate. This process lowers the temperature of the surrounding air or liquid, effectively creating the cooling effect that is fundamental to refrigeration.

The other processes involved in a refrigeration cycle, such as condensation, compression, and expansion, play significant roles as well, but they do not directly result in the cooling effect. Condensation releases heat when the refrigerant transitions from gas to liquid, compression raises the pressure and temperature of the refrigerant vapor, and expansion decreases the pressure of the refrigerant, preparing it for evaporation. However, it is the evaporation process that specifically facilitates the absorption of heat, leading to the cooling effect.
