What is the primary purpose of the evaporator in an air conditioning system?

The primary purpose of the evaporator in an air conditioning system is to absorb heat from the indoor air. In the process of cooling, the evaporator coil uses a refrigerant that evaporates at low pressure and temperature. As indoor air passes over the evaporator coil, the refrigerant inside the coil absorbs heat from the air, causing the refrigerant to evaporate into a gas. This heat absorption results in a drop in air temperature, thereby cooling the indoor environment. This fundamental role of the evaporator is essential in achieving the intended temperature control and comfort in air conditioning systems.
