Air Handling Units (AHU) play an essential role in creating healthy and efficient indoor environments. AHU are vital for maintaining air quality, temperature control, and ventilation in commercial, industrial, and residential buildings. AHU manufacturers are constantly innovating to meet energy-efficient and sustainable solutions to grow. We provide high-quality, reliable, and customizable AHUs designed to improve indoor air quality and energy efficiency.
What is Air Handling Unit
Air Handling Units (AHU) are essential components of a building’s HVAC. HVAC stands for Heating, Ventilation, and Air Conditioning. They are responsible for circulating and conditioning the air within a building, ensuring proper ventilation, temperature regulation, and humidity control. AHUs consist of filters, fans, dampers, heating and cooling coils, and other components that work together to provide clean, comfortable air.
AHU takes in outside air, conditions it (by heating, cooling, humidifying, or dehumidifying), and distributes it throughout the building. AHUs are used in various applications, from large commercial spaces like shopping malls, hospitals, and office buildings to industrial settings and residential complexes.
Air Handling Unit Types
Air Handling Units (AHU) are classified based on their design, application, and functionality. Here are the main types of AHUs:
- Packaged Air Handling Units (PAHU)
- Modular Air Handling Units (MAHU)
- Rooftop Air Handling Units (RTU)
- Double Skin Air Handling Units
- Single Skin Air Handling Units
- Ceiling-Mounted
- Fresh Air Handling Units (FAHU)
- Heat Recovery Air Handling Units (HRU)
- Floor-Mounted Air Handling Units
- Fan Coil Units (FCU)
Air Handling Unit (AHU) Working Principle
- Air Intake: An air intake is a system that controls and captures air for an engine or combustion chamber. It can be found in vehicles, aircraft, and other devices.
- Air Mixing (Optional): Fresh air and return air can be blended in the AHU’s mixing chamber. This reduces the amount of energy needed for cooling/heating by reusing part of the indoor air.
- Air Filtration: Air filtration is the process of removing airborne particles from the air. It’s used to improve indoor air quality and protect people and objects from harmful substances.
- Cooling or Heating Coils: A “cooling coil” or “heating coil” refers to a component within an HVAC system that either absorbs heat from air to cool it down (cooling coil) or transfers heat to air to warm it up (heating coil)
- Humidification/Dehumidification (Optional): Humidification and dehumidification are processes that add or remove moisture from the air. They are used in a variety of applications, including air conditioning, water desalination, and chemical engineering.
- Fan Section: After the air is conditioned (cooled or heated), it passes through a fan section. The supply fan blows the treated air into the building’s ductwork, distributing it to various zones or rooms.
- Air Distribution: Air distribution is the process of moving air into and out of a space, such as a building or room. It’s achieved using ducts, vents, and other components.
- Air Return (Optional): After the air has been circulated through the space, it is either returned to the Air Handling Units (AHU) through return ducts or vented out of the building. Some AHUs recirculate a portion of the return air to improve energy efficiency, especially in systems where temperature control is critical.
- Control System: A control system is a set of devices that regulate other systems or devices using control loops. Control systems can be mechanical or electronic, and are often computerized. They are used in many industries to improve efficiency, safety, and production.
- Optional Components: In energy-efficient systems, an HRU is used to recover heat from the exhaust air and transfer it to the incoming fresh air, thus reducing the energy needed for heating or cooling.
