AHU System.

An air handler unit (AHU) is a critical component of your air conditioning system. It is used for circulating air throughout your home. It is typically located inside the house, either in a closet, attic, or basement. It works with an air conditioner or heat pump to distribute conditioned air.

An air handler pulls in air from your home through a return duct, passes it through a filter to remove dust or debris, etc and then pushes it through a series of coils. These coils are either heated or cooled up on seasonal requirements, and the air is then distributed through your home via a network of ducts.

The air handler also contains a blower motor responsible for pushing the air through the system. This motor can be adjusted to control the speed of the air, allowing for more precise temperature control.

Types of AHU Units.

Air Handling Units (AHUs) are crucial components in HVAC that condition and distribute air within buildings. Here are several types of AHUs commonly used in various applications:

  2. Multi-Zone AHU: Multi-zone AHUs can serve multiple areas or zones within a building. They allow different temperature or airflow settings in different zones, providing flexibility and individual control.
  3. Constant Air Volume (CAV) AHU: CAV AHUs maintain a consistent airflow rate regardless of the space’s changing heating or cooling load. They’re suitable for areas with relatively stable temperature requirements.
  4. Variable Air Volume (VAV) AHU: VAV AHUs adjust the airflow based on the space’s varying heating or cooling needs. They can modulate the air volume to individual zones, providing better energy efficiency by matching the airflow to the demand.
  5. Heat Recovery AHU: These units recover heat from the exhaust air and use it to preheat or precool incoming fresh air, improving energy efficiency by reducing the load on heating or cooling systems.
  6. Ceiling Mounted AHU: These units are designed to be mounted on the ceiling, typically in spaces with limited floor space, such as server rooms or areas where floor installation is challenging.
  7. Modular AHU: Modular AHUs offer flexibility by allowing additional modules to be added or removed as per the changing requirements of the building. They’re adaptable and scalable.
  8. Indoor AHU: Indoor AHUs are installed within the building and are often part of larger HVAC units. They condition and distribute air within the building space.
  9. Outdoor AHU: These units are installed outside the building and are responsible for taking and conditioning fresh air before it enters the building. They’re commonly used in ventilation systems.
  10. Custom AHU Configurations: AHUs can be customised based on specific requirements, incorporating features such as unique filtration systems, energy recovery systems, or specialised controls to meet individual needs.
  • The choice of AHU depends on factors like the building size, layout, zoning requirements, energy efficiency goals, and specific needs of the space it serves. Each type of AHU offers different functionalities and advantages, catering to various applications and environments.

How to Choose the Right Air Handler unit ?
