Air Handling Unit

The requirement for ventilation is present everywhere and is very important in companies where many appliances like computers are used. It can be a house or a big building which belongs to a business, everywhere ventilation is very important to keep the temperature adequate and the conditions clean and hygienic. An air handling unit is a big boxed shape machine that basically does the work of air purification, air conditioning, or completely changing the air of a specific closed area to increase the cleanliness and keep the people there, comfortable and healthy. These machines are most commonly present on the top of a building and the ventilation is done with the help of a duct system installed inside the building. The main usage of the air handling unit is that it can be used to reduce the temperature of the interior environment because the machine can function as an air conditioner. The main function of an AHU is that it is used to regulate the air inside a building and with the help of a purifying system, the air can be cleaned and fresh & clean air can be provided to everyone present inside the building. Another use of the AHU is that it can control the amount of humidity inside the building and can be very useful to limit the number of water vapors present inside the building. This feature can help people suffering from asthma and other respiratory diseases. There are multiple parts inside an AHU that includes 1. An air intake which gathers air from outer surroundings and after purification the air is distributed inside the building, 2. A filter that purifies the air entering through the air intake and makes it free from microbes and dust, 3. A fan that transports the treated air into the building through the air ducts installed in the building, 4. Heat Exchangers, which helps to reduce the temperature of the air to act as an air conditioner, 5. Cooling coil through which the air passes when it is being cooled, and 6. Silencer which effectively reduces the sound produced by the air handling unit. The ultimate goal of installing an air handling unit is to reduce energy consumption while getting safe and healthy air to breathe in. By having AHUs with heat recovery systems, the working efficiency of the machine is increased and the cooling effect can also be used along with the purification of the air, entirely removing the need for an air conditioner hence reducing more energy consumption.
