AHU Working Process and Functionalities
Understanding Segments of the AHU Unit
BlowerÂ
The blower, which is responsible for recycling the air in the building, is a key component of every piece of air handling equipment. The blower absorbs air, which is either heated or cooled before being released into the structure. Commercial buildings’ air handling devices might have several blowers or fans for additional efficiency.
Conditioning ElementsÂ
The elements that assist in heating or cooling the air are the second-most crucial parts of an air handling unit. Heating coils are used for this purpose in heating systems. The oil in the air conditioning systems is cooled using cooling coils. Other conditioning components utilized for this include steam, hot water, and cold water.
Filters
The filter is one of the key parts of AHUs. A building’s air must be properly cleaned in addition to being properly conditioned. Filters are installed in air handling devices to serve the purpose of cleaning and purifying the air by eliminating dust and other unwanted elements. Keep in mind that filters extend the lifespan of an air-handling device overall.
Humidifier
In AHU systems, humidifiers maintain the quality of the air in regions with cold climates. Without these elements, the air may dry out significantly from frequent heating. Different units contain various humidifier types, such as vaporizers and ultrasonic humidifiers.
Mixing chambers and dampers
Dampers serve another crucial purpose and are mounted inside the mixing chamber of an air handling unit. To condition the air more quickly and easily, this entire setup mixes exhaust air from the inside of the building with intake air from the outside.
Additional Components and Their Activities
To increase the air handlers’ energy efficiency, many types of heat recovery equipment are used. The noise and vibrations that air handling equipment produces can also be controlled using sound attenuators and vibration isolators. To detect smoke and avoid fire mishaps, smoke detectors are also installed in these units. The blower’s speed is controlled by duct pressure control mechanisms. Other parts that control various functionalities of these gadgets include sensors and controllers.
AHU Unit’s Durability & Maintenance
When you invest in an air handling unit, ‘How long will AHU perform?’ is likely to be one of your first concerns. Everything relies on several important elements, including the concept of design and construction, installation, and maintenance.
Facts that affect AHU’s Long Run
Additional elements that may shorten the life of your air handling equipment include:
- Ensuring that the AHU complies with industry requirements
- Utilize intensity.
- The AHU’s performance, as well as its installation, commissioning, and upkeep
- Any access to the external environment where the AHU is placed.
- The ducting type next to the AHU
- Weather conditions
- AHU size with demand, uses, and requirements
Maintenance requirements for Air Handling Units (AHU)
- Seasonal maintenance
- The filters are typically changed every 1–4 months.
- Checking and replacing refrigerant insulation
- Regular exterior and interior cleaning and dirt removal of the unit
