Which component of an HVAC system is responsible for heat removal in refrigeration?

The evaporator coil is responsible for heat removal in refrigeration systems. In the refrigeration cycle, the evaporator coil is the component where refrigerant absorbs heat from the indoor air or the surrounding environment. As the refrigerant flows through the evaporator coil, it evaporates from a liquid to a gas, absorbing heat in the process. This heat absorption leads to a cooling effect in the space being conditioned.

The evaporator coil plays a critical role in transferring heat away from the air, thereby lowering the temperature in the indoor environment. This is essential for maintaining comfortable conditions in buildings, refrigerators, and other cooling applications. Therefore, understanding the function of the evaporator coil helps clarify its importance in effective heat removal within HVAC systems.
