Evapoler is manufacturer, supplier and exporter of Air Handling Unit s in india. The basic function of the AHU is to take in outside air, re-condition it and supply it as fresh & cool air to a building.The AHU’s are manufactured in varied configurations-Floor Mounted Type, Vertical type and customised one as per customer specific requirement. The product quality is top most priority. The quality check and monitoring starts right from design & raw material selection. The product is manufactured and made available both in 25 mm puff insulated double skin with or without thermal break profile as per requirement. The Air Handling unit are manufactured both in Single tier and two tier as per need of the project. Our Air Handling units are appreciated by Clients and user industries for its durability and best quality at competitive prices.
Air Handling unit (AHU)s finds applications for process cooling in industries and for comfort cooling in offices, institutions ,hotels, hospitals ,airports ,shopping malls ,commercial complexes ,Restaurants ,Residences and many more.
An air handling unit, commonly called an AHU, is the assembly of various components to fulfil ventilation requirements for better indoor air quality and air-conditioning in a building or shop floor area.
They are usually installed on the roof of buildings and air distribution is achieved through ducts, to reach each of the rooms in the building to be conditioned.
Main functions of an AHU
In addition to providing proper ventilation inside the building with outside air, the AHU performs other functions as well:
Air Filtration and control of the quality of the air that will reach the interior with high efficiency filters.
Control of the air temperature that regulates the air conditioning system in cold or hot, so that the indoor environment is comfortable.
Relative humidity monitoring for greater indoor comfort.
CO monitoring for Indoor air quality.
For its part, the places for which the AHU is intended are those in which the movement of people is very large and accumulates many people at the same time and whose natural ventilation is limited: Commercial buildings ,hotel dining rooms, function rooms, restaurants, convention halls… It is also a suitable option for those spaces with very high hygiene requirements: laboratories, clean rooms or operation theatres, among others. An AHU can also be used to ventilate places where air conditioning is provided by radiators or underfloor heating.
What does an AHU consist of?
Air intake: air handling units collect air from outside, which is treated and distributed throughout the rooms; and/or indoor air that is “recycled”.
Filter: depending on the air purity requirements, the filter used will have a higher or lower particle, viruses, bacteria, odours, and other air pollutants retention.
Fan: this is an electromechanical system that powers the air to expel it from the AHU to the ducts that distribute the air throughout the rooms.
Heat exchangers: devices that transfer temperature between two fluids, in this case, coolant and air, separated by a solid barrier.
Cooling coil: the air passing through this module is cooled. In this process, water droplets can be generated, which are collected in a condensate tray thanks to the built-in droplet separator.
Plenums: empty spaces in which the air flow is homogenised.
Energy efficiency of AHUs
Post Covid – aim of an air handling unit is Disease resiliency and energy efficiency. By utilising UVG irradiation , high efficieny air filters like MERV13 or Hepa Filters- the disease resiliency achieved. By using heat recovery units i.e by passing return air and incoming fresh air in different channels of heat exchanger the fresh air load is reduced on cooling coil which renders it energy efficient.
Further with use of variable frequency drive and thus with control of fan speed as per the flow rate needs, power consumption can be optimised.
