What is the primary function of the evaporator in the refrigeration cycle?

The primary function of the evaporator in the refrigeration cycle is to transfer heat from the refrigerant to the surrounding environment. In the evaporator, the refrigerant absorbs heat from the indoor air, which causes it to evaporate and change from a liquid to a vapor. This process cools the air that is circulating over the evaporator coils, thereby lowering the temperature of the indoor space.

This function is critical for the overall cooling effect of the refrigeration system. By absorbing heat, the evaporator helps maintain the desired temperature within a space, making it an essential component in air conditioning and refrigeration applications. The efficient operation of the evaporator is key to ensuring that the entire cooling system performs effectively.
