- An Air Handling Unit (AHU) is a crucial component in HVAC (Heating, Ventilation, and Air Conditioning) systems that regulate the air quality and temperature within a building. AHUs work by circulating and conditioning the air, including cooling or heating it, filtering it, and distributing it to different areas of a building through a network of ducts.
AHUs are made up of several components, including fans, filters, heating or cooling coils, humidifiers or dehumidifiers, and control systems. The fans in AHUs draw in outside air or recirculate indoor air, which is then filtered to remove impurities such as dust and pollen. The air then passes over the heating or cooling coils, where its temperature is adjusted to the desired level. If necessary, humidifiers or dehumidifiers can also be used to regulate the humidity levels in the air.
The control systems in AHUs are responsible for monitoring the air quality and temperature, and adjusting the AHU's operation accordingly. This can include adjusting the fan speed, adjusting the temperature of the heating or cooling coils, or turning on humidifiers or dehumidifiers.
AHUs are used in a wide range of buildings, including offices, hospitals, schools, and industrial facilities. They are essential for maintaining a comfortable and healthy indoor environment, by providing fresh air, regulating temperature and humidity levels, and removing pollutants from the air.
Overall, AHUs play a critical role in HVAC systems, and are an important part of maintaining a comfortable and healthy indoor environment.
In the previous video of Chiller you told Water coming out of AHU is at a temperature of 12 deg celcius but here it is 9deg .. Explain it sir please..
Actually the return temperature from the AHU will vary based on the heat in the room. It can vary from 9°C to 15°C or more than this.
How about the chilled water ...what temperature leaving from chiller to AHU?
In most of the commercial building the Chilled water leaving from the Chiller to AHU at 6°C.
very good video, thank you. I am having a problem, there is so much condensation in the exhaust fan chamber, it is flowing outside the AHU. Can you explain to me!! Thanks a lot !!
Sir explain DX system what is DX system? And working in FCU and AHU
Very goods vodio brother next video make the chiller sefty divice
Thank you so much for your appreciation. Sure I will make the video as per your request.
How to find
Efficiency
Approx
And delta T of a cooling tower and chiller please make a video on it
Thank you Sir , very nice video , i learn alot from your videos😊
I am glad. Thank You 😊
What about the fresh air? Don't need to add fresh air to the AHU? Only circulating the same air??
At the end I have mentioned about the fresh air. We should add fresh air in the AHU to keep the oxygen level inside the building.
Great Video and well explained 👏👏
Thank you! 👍
Can you explain ahu working in accu unit.. i mean with freon refrigerant cooling system.. most of the videos are with chilled water system...
also the crac units..
How sucking the room air
Brother where are you from
Hi Bro, I am from India.
Goa India
Very good 💯 bro ...bro I nead video water flashing in this system.
Sure, I also thinking about this and will make a video with this topic.
Thank You for your suggestion.

Hi does AHUs have compressor?...if so what's the application
No, AHUs don't have compressor.
@@zebralearningsenglish-pn6fl Thank You for confirming.
Great explanation and could you please explain for RTU ??
Thank you 😊 and sure I will explain about Roof Top Unit soon.

Reqest for my side make video off BMS operator
Yeah sure. I'll upload about BMS also in the future videos.

NOTHING is said about relative humidity or condensate. If moisture is removed from the air then the relative humidity is 100%.
What are the details you need? Just let me know, and I'll try to make a video of it.
Sir y is ahi kit fixed and when is it required
AHU is like Air Conditioner. It is used in large area to make the temperature comfortable.
Amazing content. Thank you.
My pleasure!
Is humidifier used in A hu system
Humidifier is not used inside the AHU. The Humidifier is installed outside and the steam only conveyed into the AHU the through the pipeline. But not all the AHU has the humidifier. It's based on the requirement.
Nice video, simple and good explain
Thank you 😊😊
Very good explanation sir
Thanks
Very informative...Can we have some video in basic computaion of service area to cool down and the size of AHU
Yes, soon 👍
Thank for you help,🤔
Happy to help
How about the fresh air
The fresh air is explained in this video,

What will be the return air temperature
The return air temperature is depends on the many factors like heat production in the room. But in a office room the temperature vary between 22°C to 26°C.
@@zebralearningsenglish-pn6fl Ok sir.Thank you
thank you so much sir ☺️😊
Thank You 😊
👍
👍😊👍
What is duct
A duct is a tube, pipe, or enclosed channel designed to carry air. The air is passing through the duct.
Very good experience ❤
Nice presentation
Thanks a lot
Greatly explained
Glad it was helpful!
Good 😊😊
Thanks 😊
Ahu connect with??
The chiller system.
The water temp rises
So it goes back to the chiller to cool down again.
AHU water supply is connected with the chiller and the duct system is connected with the room.
Great
Thank you 😊
thank
Thank you 😊
Very useful sir
Thanks and welcome
Good explained brother
Thank you brother. Please keep support.
