The evaporator is the component of an air conditioning system that is responsible for removing heat from the ambient inside air. It does this by allowing the refrigerant to absorb heat as it evaporates from a liquid to a gas. As warm air from the room passes over the evaporator coils, the refrigerant inside those coils absorbs that heat, cooling the air in the process.

This cooling effect occurs because the refrigerant is maintained at a low pressure in the evaporator, which enables it to absorb heat effectively. Once the refrigerant has absorbed enough heat, it then moves to the compressor to continue the cycle, where it will be compressed and sent to the condenser to release the heat absorbed.

The compressor, condenser, and accumulator have different roles in the air conditioning system. The compressor increases the pressure of the refrigerant, the condenser dissipates the heat that has been absorbed from inside the space to the outside environment, and the accumulator helps store excess refrigerant and ensure the proper flow in the system. Understanding these roles helps clarify why the evaporator is critical for cooling the indoor air.
