In an air conditioning system, what component extracts heat from the air?

The evaporator is the component in an air conditioning system that primarily extracts heat from the air. It works by absorbing heat from the indoor environment as refrigerant passes through it. The refrigerant, which is at a low pressure and temperature, enters the evaporator coil and evaporates into a gas, absorbing heat in the process. This heat exchange cools the surrounding air, which is then blown into the living space.

In this process, the refrigerant changes its state from liquid to gas, effectively removing heat from the indoor air. This is crucial for the cooling function of air conditioning systems. The heat collected from the indoor air is later released outside when the refrigerant passes through the condenser. Understanding the role of the evaporator helps clarify its essential function in maintaining the desired indoor temperature.
