AHU in HVAC System

AHU in HVAC System

AHU stands for Air Handling Unit, which is a critical component of an HVAC system. Here's a closer look at its functions and features:

Functions of an AHU

Air Circulation: The AHU is responsible for circulating and distributing conditioned air throughout a building.

Heating and Cooling: It can regulate the temperature of incoming air by heating or cooling it, depending on the season.

Filtration: AHUs often include filters to remove dust, allergens, and other particulates from the air.

Humidity Control: Some units have humidifiers or dehumidifiers to maintain optimal humidity levels.

Ventilation: AHUs can introduce fresh outdoor air into the system, improving indoor air quality.

Components of an AHU

Fan: Circulates air through the unit and into the ductwork.

Coils: Heat exchangers that either heat or cool the air.

Filters: Capture airborne particles to improve air quality.

Dampers: Control airflow and can adjust the mix of indoor and outdoor air.

Controls: Regulate operation based on temperature, humidity, and air quality sensors.

Importance in HVAC Systems

AHUs play a crucial role in maintaining comfort and air quality in commercial and residential buildings. They are integral to the efficiency and effectiveness of the overall HVAC system. Proper maintenance of AHUs is essential for optimal performance and energy efficiency.
