Best AHU Manufacturers In India 

What is an air handling unit?

An item of machinery that manages air is referred to as a "air handling unit," occasionally spelled "AHU." It has a very basic internal structure. The central air conditioning system's beating heart is the air handling unit (AHU). It gathers indoor and outdoor air, filters out dust and other material, alters the temperature and humidity, and then uses ducts to distribute cold, comfortable air conditioning into the rooms. Before actually hiring the Best AHU Manufacturers In India, you must be knowledgeable about AHU.

What is an air handling unit ?

An air handling unit is essentially a huge indoor piece of commercial air conditioning machinery. This enormous "indoor unit" is fastened to a building's roof or outside wall. In order to cool or heat the rooms, it produces chilly or warm air. Air handling systems, in contrast to ordinary commercial air conditioners, are often constructed on demand for particular structures. Additionally, air handling systems can be fitted internally with humidifiers, filters, and other controls for temperature, humidity, air flow, and air quality.

A filter, humidifier, blowers (fans), and heat exchanger are commonly housed in the housing of an air handling device (fins). Absolutely no sophisticated mechanism exists. The procedure is fairly simple.

Central air conditioning

In order to accurately understand the function of an air handling unit (AHU) and choose the Best AHU Manufacturers In India, it is crucial to understand the concept of central air conditioning.

Using heat source equipment situated in a single location throughout the building, a system known as central air conditioning delivers chilled or heated water to the air handling unit for use in cooling or heating the rooms. In contrast, "individual air conditioning" refers to a system that requires the scattered installation of numerous heat source devices, such as one unit per floor or per space, and is installed by Top ahu manufacturers in India.

Mechanism of central air conditioning by Top 10 AHU manufacturers in India

Air handling units and fan coils are used by central air conditioning systems to offer both cooling and heating. Heat source devices are also utilised (such as a boiler, refrigerator, etc.). Central air conditioning is also referred to as centralised air conditioning since all heat sources are put in one location throughout the building and chilled or heated water is supplied to the air conditioning units to cool or heat the rooms. Large buildings and facilities commonly use central air conditioning systems that are installed by air handling unit manufacturers.

Advantages of central air conditioning

The benefits of central air conditioning are numerous. It allows for variable water piping design and flexible installation location choices for chillers and air handling units, such as those installed by Indian manufacturers of air handling units (AHU). Minimum length restrictions apply to the chilled/heated water pipes and the air delivery ducts when using central air conditioning. As an illustration, when a central air conditioning system is in the cooling mode, the chiller generates chilled water, which the air handling unit (AHU) then feeds to the cold water coil where it conducts heat exchanges with the surrounding air. The fans then circulate the cooled air via the ducts. Therefore, central air conditioning can efficiently heat or cool huge spaces and buildings, depending on how the equipment and devices are configured. Furthermore, because huge water pumps and air blower fans are utilised, there is no need to worry about the top limitations of refrigerant tube height difference, tube length, air flowrate, or static pressure, unlike with direct expansion type air conditioners.

Function of air handling unit

Let's look at the functions that central air conditioning's air handling units do. As was already said, an air handling unit is a huge interior commercial air conditioning equipment. This enormous "indoor unit" is situated outside. It produces, distributes, and moves heated or cooled air into the rooms via ducts. The majority of the time, air handling units are designed specifically for each customer. They can also be modified to accommodate unique requirements and architectural details.

Air handling equipment are widely employed in large, heavily used places like theatres and retail malls. Large public areas are subject to strict regulations limiting the release of carbon dioxide and the quality of the air, which is one of the reasons behind this. In order to circulate the air and let a lot of air into the building, a large facility needs to use a lot of blower fans. Less blower fans are required because the air handling systems carry outside air into the rooms.

Additionally, factories and other locations that handle flammable gases employ air handling devices. In an environment where combustible gases are present, sparks from an electric device have the potential to cause an explosion. As a result, in these places, explosion-proof air handling devices or equipment is used.

Mechanism and air conditioning method of air handling unit

An air handling unit design was described as a large indoor unit in the section before, although they are unable to independently cool or heat rooms. They require a variety of tools, such as heat-generating machinery that can also function as an outside unit. Commercial outdoor air conditioning units (VRFs), chillers, or cooling towers are used to send chilled or heated water to air handling systems for cooling.

An air handling unit contains a hot/cold water coil, reheat coil, humidifier, air filter, blower fans, and other parts. In certain machine rooms, air handling equipment are installed. Due to the unitization and integration of all internal devices into the air handling unit, maintenance and inspection are straightforward to do. To regulate the air temperature, air handling systems use a chiller or a variable refrigerant flow (VRF) system as the heat source. Air handling systems thus provide a high degree of operational flexibility. For instance, medium- and large-sized structures can be installed with a combination of chillers and air handling units, whereas small and medium-sized structures can make use of VRFs and AHUs.

Advantages of air handling units

One of their advantages is the capacity to instal numerous air handling devices at a single external site. Indoor units must be put separately in each room whereas outdoor units are often installed on rooftops or along exterior walls of buildings for standard commercial air conditioning. Each indoor unit that is installed in a room also requires maintenance, which is both expensive and time-consuming. On the other hand, it is feasible to group and instal all of the air handling devices at a single outdoor location, making maintenance there possible.

Disadvantages of air handling units

Air handling systems have disadvantages as well. If the air handling equipment fails, the entire building won't have air conditioning. Installing additional air handling systems is important to offer backup.

Commercial air conditioner and air handling unit distinctions

An air handling unit creates cool or warm air at one site and distributes it to many rooms, unlike a traditional air conditioner, which uses the separate indoor units located in the rooms, as was mentioned in the previous section. This is the key difference between an air handling unit and a regular air conditioner. Another difference is that the air handling unit cools or heats air that is drawn in from the outside and sends it to the rooms, as opposed to a normal commercial air conditioner, which draws in room air, cools or warms it, and then exhausts it into the room.

Differences between a fan coil and an air handling unit

In a sense, air handling systems are installed to cool or heat the entire building, whereas fan coils are employed to cool or heat certain rooms. Fan coils require the use of an additional heat source medium. The heat source for fan coils is commonly water that has been heated or chilled. Water that has been heated or chilled at another site is sent to the fan coil unit to be used in giving warm/cold air to the rooms.

Maintenance of air handling unit

An air handling unit is made up of a filter, humidifier, blowers (fans), and a heat exchanger (fins). Because some air handling devices are large enough for human entry, engineers periodically enter them for maintenance. An air handling unit can accommodate the installation of any kind of air filter, from a coarse filter to a fine filter known as a HEPA filter. However, the filter must be cleaned with a vacuum or cleaning supplies because it gathers dust. Chemicals are used to make it easier to eliminate chlorine before cleaning the humidifier when it sticks to the appliance. The blower fans also accumulate dust. Chemicals must be used to clean and remove stubborn dirt from the fans. During cooling operations, condensation water that covers particular areas of the heat exchanger may promote the development of fungus.

Chemicals are therefore required to clean the heat exchanger. Maintenance is carried out in the spring or fall, when the air conditioners are not in use.
