Is An Evaporator An Air Handler?

Is An Evaporator An Air Handler

No, an evaporator is not the same as an air handler, although they are both components of HVAC systems and often work together.

Evaporator

Function: The evaporator is part of the cooling process. It absorbs heat from the indoor air and cools it by evaporating a refrigerant.

Location: Typically located inside the air conditioning unit or a heat pump system.

Role: Converts liquid refrigerant into vapor, absorbing heat from the air, which lowers the temperature of the air that is then circulated throughout the space.

Air Handler (AHU)

Function: An air handler circulates and conditions air, including filtering, heating, and cooling.

Components: Includes a blower, heating and cooling coils, filters, and dampers.

Role: Works to maintain indoor air quality and comfort by moving conditioned air throughout a building.

Key Differences

Purpose: The evaporator specifically focuses on cooling by removing heat, while the air handler is responsible for circulating and conditioning air.

Components: The evaporator is a specific component within the cooling system, whereas the air handler is a broader unit that may include the evaporator as part of its operation.
