An Air Handling Unit (AHU) is a machine that can circulate and condition the air in a space. In other words, an AHU unit from the top AHU manufacturers in India is a box containing filters, fans, and coils managing the air inside. The HVAC system connects the AHUs and is primarily responsible for various tasks, including heating, cleaning, adding humidity to the air, and cooling.
But only some AHUs perform similarly and include some basic functionality. By selecting the AHU unit from the best AHU manufacturers in India, performance can vary accordingly. The functions also vary according to the climatic temperature of the area where the AHU is operating. Some units of the top AHU manufacturers in India may deliver heating, air conditioning, and air circulation, while others may offer only air circulation. People often customize AHUs according to the building or house size to ensure all the necessities are met. Thus, it is important to understand the factors you should consider before purchasing a unit from the top AHU manufacturers in India.
Different Types of AHU Units
There are primarily 3 types of AHU units, as mentioned below.
- Horizontal mount on the floor
The based tray aligns with all the primary components of this AHU unit, making it maintenance friendly.
- Ceiling suspended
These units chiefly hung from the ceiling inside the zero floor space and false ceiling.
- Vertical mount on the floor
The units from the best AHU manufacturers in India are designed to occupy fewer spaces.
Primary factors to look for while selecting an AHU unit from the top AHU manufacturers in India
While selecting an AHU, there are 3 primary factors to look for to make sure you are buying the most cost-efficient and operationally effective machine. Let us take a look at those three aspects below.
- Airflow
Airflow is the most important factor that AHU handles. Once you know the airflow, you can easily determine what capacity and size AHU you require. The air amount an AHU distributes, and conditions are measured in liters per second. You have to first calculate the thermal load and volume of the area that needs conditioning. This way, you can determine how many AHU units you need for the area.
- Modularization and Dimensions
Regarding the AHU size from the top AHU manufacturers in India, you should consider the unit need to put up the filters and heat exchangers, and the different segment is accessible for fans and maintenance. It is also necessary to keep the plant room space in mind while maintaining all the building regulations. Engineers often use detailed BIM or 3D unit representations in the designing or planning stages of the building to make sure the AHU unit is of appropriate size for the space. AHU can be installed in modules due to its unnatural shape. In this scenario, you must consider the door and elevator sizes.
- Energy recovery and fans
You also need to check the proximity and size of the fans of the AHU unit delivered by the best AHU manufacturers in India. The fan impeller in the AHU unit by the top AHU manufacturers in India influences fan effectiveness. It is also important to consider the fan style, as belt-driven fans need more maintenance than direct-driven fans whenever the belt drive becomes worn.
Never skip energy efficiency while looking for an AHU unit from the top AHU manufacturers in India. Before buying, check out the trade-off pressure and thermal efficiency drop. The cooling recovery is dependent on the climate of the area used. In cold climates, the cooling recovery decreases the cooling power amount required. Efficiency can be increased when combined with thermal by-pass and enthalpy recovery.
FAQ: What are the different parts of AHU?
The different parts of AHU unit from the best AHU manufacturers in India includes separate ventilators for exhaust and supply, heating and cooling coil, and heating and cooling recovery system. It also contains air filter chambers, racks, mixing chambers, dampers, and sound attenuators.
Other Primary factors to consider while buying AHU by the top AHU manufacturers in India
Other factors to consider while selecting an AHU unit include the following:
- Drip eliminator
- Anti-corrosive coil coating
- Humidifiers
- Direct or belt drive for the fans
- De-humidification
- Different fan frequency drive
- Belt and pulley selection
- Volume control dampers
Conclusion
The AHU unit is a complicated machine with various components and considerations. Thus, sometimes it becomes tough to examine which functionalities and features are significant and can keep the unit running efficiently and smoothly. Thus, to help you make an informed decision, consider the above factors and buy the best unit for your space.
