Posted on 07 February, 2024 | air handling units
Considered as a part of air conditioning, HVAC system, an air handling unit’s primary job is to refine the outside air and recirculate it inside a building. The applications of air handling units are commonly found in commercial and industrial structures. These units are mostly placed on the roof of the buildings or in the basement.
An air handling unit first sucks in the outside air, filter it, cool or heat it, adds or removes moisture before sending it to the inner environment of a building. The air is transported to various parts of a building through a network of ducts and vents. Most air handling systems come with extra ducts and vents to take in the stale air and sent it back to the AHU, which is then thrown out into the atmosphere through a fan.
Apart from doing precise temperature control, HVAC systems play a crucial role when it comes to managing indoor humidity levels. When set on cooling mode, HVAC systems tend to bring down humidity by abbreviating moisture from the indoor environment onto the cooling coil, which is then thrown away. When set on heating mode, the system adds more humidity into the indoor setting whenever required, this is particularly common in the dry summers.
The best air handling unit remains an internal part of an HVAC system, commonly placed within a big metal box, situated either on a roof, in a basement, or a custom-designed designed cupboard. This unit is made up of several elements with each component leading to the general efficiency and performance of the entire unit.
Blower or fan: The blower or fan promulgates the treated air inside a building, pouring the program of air that required conditioning, and dispensing the treated air through ducts. It is necessary to upkeep steady uniform indoor temperature and air quality.
Heating and cooling parts: The evaporator coil and the furnace or heat exchanger or furnace, are considered important parts of an AHU and meant to regulate the temperature. The evaporator coil reduces the air’s temperature by removing its heat, whereas the heat exchanger or furnace heats up the air, usually through fuel burning or electric heating.
Filter racks or chambers: These elements are meant to grasp the air filters within the AHU, which are vital for upholding indoor air value. They snare airborne pollutants such as allergens, and dust, averting their circulation in the indoor setting.
Sound attenuators: Sound attenuators, or silencers, engross sound surfs produced by the HVAC system process, ensuring reduced noise and safeguarding a passive indoor environment.
Dampers: Dampers simply means the ‘valves’ of an HVAC system and are meant to airflow through a network of ducts. They help control and uphold steady temperatures in diverse areas of a building, resulting in enhanced comfort and competence.
Air handling units are connected straight to a building’s ductwork. This can be understood as a web of pipes that transports conditioned air to various parts of the building. The ductwork is also responsible for carrying back the air to the AHU, where it is re-cleansed and overhauled.
Decoding the prominent role of customized air handling units in HVAC systems helps underline the standing of appropriate air handling. The AHU not only guarantees comfort through temperature control but also meaningfully underwrites the health and overall well-being of inhabitants by improving the overall quality of the indoor air.
The HVAC system, and precisely the air handling unit (AHU is considered a critical element when it comes to guaranteeing comfy, healthy, and energy-efficient environments. This is particularly true in regions that have distinctive weather settings. Handing the air in proper way is necessary to upkeeping good indoor air quality, instilling integrity, and resident’s health and easiness, while also safeguarding compliance with the applicable regulations and values.
