What is an air handling unit?
An air handling unit (AHU) is a piece of equipment that is used to condition the air in a building. It does this by filtering, heating, cooling, and humidifying or dehumidifying the air. AHUs are typically used in commercial buildings, but they can also be found in some homes.
Types of air handling units
There are many different types of air handling units, each with its own advantages and disadvantages. Some of the most common types of AHUs include:
- Packaged AHUs: Packaged AHUs are all-in-one units that contain all of the components needed to condition the air. They are typically the most affordable type of AHU, but they are also the least flexible.
- Split AHUs: Split AHUs consist of two units: an indoor unit and an outdoor unit. The indoor unit contains the fan and coils, while the outdoor unit contains the compressor. Split AHUs are more expensive than packaged AHUs, but they are also more flexible.
- Centralized AHUs: Centralized AHUs are typically used in large buildings. They consist of a single unit that is located in a central location, such as the basement or roof. The air is then distributed to the rest of the building through a network of ducts. Centralized AHUs are the most expensive type of AHU, but they can also be the most efficient.
How do air handling units work?
Air handling units work by passing the air through a series of filters, coils, and fans. The filters remove dust, pollen, and other pollutants from the air. The coils heat or cool the air, and the fans distribute the air throughout the building.
Benefits of using air handling units
There are many benefits to using air handling units, including:
- Improved air quality: Air handling units can improve the air quality in a building by removing pollutants and allergens from the air. This can help to reduce respiratory problems and improve overall health.
- Increased comfort: Air handling units can help to keep the air in a building at a comfortable temperature and humidity level. This can help to improve productivity and reduce absenteeism.
- Reduced energy costs: Air handling units can help to reduce energy costs by providing more efficient heating and cooling.
- Improved indoor environment: Air handling units can help to improve the indoor environment by reducing noise and vibration.
Applications of air handling units
Air handling units are used in a variety of applications, including:
- Commercial buildings: Air handling units are commonly used in office buildings, schools, hospitals, and other commercial buildings.
- Residential homes: Air handling units are becoming increasingly popular in residential homes. They can help to improve the air quality and comfort in a home.
- Industrial settings: Air handling units are used in a variety of industrial settings, such as manufacturing plants, warehouses, and laboratories.
