Fresh air handling unit function

What is CFM of air handling unit? The basic function of the AHU is take in outside air , re-condition it and supply it as fresh air to a building. All exhaust air is remove which creates an acceptable indoor air quality. I will be very thankful to you. An air handler , or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning system.


An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.

FAHU is the abbreviation used for FRESH AIR HANDLING UNIT. These are usually centralized units employed to induce fresh air quantities to the confines spaces. They come into picture wherever there are limitations to fresh air intake either directly or through AHUs.


In the Draw-Through type, the fan pulls the air through the mixing box, filters and cooling coil before discharging it from the fan outlet to the space to be conditioned or to the ducting network. The design can be vertical or horizontal. In this case, the section before the fan has negative pressure. Treated Fresh Air Units (TFA) are also sometimes referred to in.


Its main function is to reduce the temperature, control the humidity and eliminates the dust particles.

An air handling unit is a device used to regulate and circulate air as part of the heating, ventilation and air conditioning system. The AHU takes in outside air , reconditions (filtered and either heated or cooled) it and supplies it as fresh air to the air conditioned room. They take fresh ambient air from outside, clean it, heat it or cool it, maybe humidify it and then force it through some ductwork around to the designed areas within a building.


In this article we will be covering this topic to understand the basics of HVAC central plant. Scroll to the bottom to watch the video tutorial on this subject. Air handling unit functions.


Installed on a common base frame, the single duct air handling unit has the following functions:​. Filtering function with EU-class filter. Heating function with electrical heater or hot-water heating coil. Cooling function with air cooler for direct expansion (of Freon) or cooling with chilled water.


In case the fresh air handling units are used exhaust process is handled by the cabinet ventilators. Heart of the TFA is energy recovery wheel only which recovers Total. The air handling unit is an integrated piece of equipment consisting of fans, heating and cooling coils, air -control dampers, filters and silencers.


The purpose of this equipment is to collect and mix outdoor air with that returning from the building space. However, there are certain HVAC applications in which a rooftop unit is not suitable, where makeup air units just make sense. Trosten Industries, located in Dubai, provides you with the most trusted and reliable Heat Recovery Units.


Air Handling Units are often called AHU.
