Types of AHU Coils

Types of AHU Coils

Cooling Coils: Used to lower the temperature of the air, typically chilled water coils or direct expansion (DX) coils that use refrigerant.

Heating Coils: Used to raise the air temperature, often utilizing hot water, steam, or electric heating elements.

Reheat Coils: Employed to reheat air after it has been cooled for humidity control, commonly found in dehumidification applications.

Functions

Temperature Regulation: AHU coils regulate air temperature by either heating or cooling the air before distribution.

Humidity Control: By cooling the air, coils can also help remove moisture, contributing to overall humidity management in indoor spaces.

Air Quality Improvement: By conditioning the air, AHU coils enhance indoor air quality, providing a comfortable environment.

Applications

Commercial Buildings: Widely used in offices, shopping malls, and other large facilities to manage climate control.

Industrial Facilities: Employed in manufacturing plants and warehouses for temperature and humidity control.

Residential Systems: Certain HVAC systems in homes utilize AHU coils for efficient climate management.
