How Air Handling Units work AHU working principle hvac ventilation

This was a really great video. Thank you!

Superb

Nicely explained

I’m a Mechanical Engineer by Trade and have done HVAC design for Years and I approve this message

I think if FAHU means Fresh air handling unit therefore the difference is that the ventilation cooling load will be much higher since theres no return air involved. Just my guess

I find the lack of return air filtration mentioned in this video disturbing.

Awesome video
Awesome explanation

It helps a lot thanks

Service engineer from the Netherlands here. Great video and explaination. I have never seen exhaust units without filter. It is common to have inlet and exhaust filters here. No matter if there is a heating wheel.

so you can use vents to scape a shooter at school as long its the exit side

Are FCU and AHU in the same system?

FRESH AIR HANDLING UNIT AND AIR HANDLING UNIT

Next level teaching

What will cause a chill to turn off

i am loving this series as the video goes on

Really helpful. Thanks 🙏

Fantastic video

FAHU is AHU but with more fans.

Bro, why am I getting this in my recommended

Don't want to breave that dirt in the aio.

Good job, thank you !!!

Question . Single family home. I had two hvac companies check my ahu.. they was working on the wiring. Nothing changed. When it’s cold, it’s colder inside than out. When it’s hot, it’s hotter inside than out

Very nice picture

I am not a engineer but FAHU is a

An AHU Is an

Thank you very much dear sir.....

these videos are too good

Great Video

@TheEngineeringMindset have you uploaded the BIM videos

AHU have a energy recover unit

Chemical dehumidifier video would be great if you have time, thank you anyways!

great explanation, now I know... thank you very much

Thank you so much🙏

This video is very helpful. Thank a lot

I'm involved with this equpiment frequently so (hopefully) the majority of the video is something I already know and am familiar with. In regards to your remark regarding centrifugal fans, I'm not entirely sure that was the proper way to describe it. Would it be more fair in your opinion to state that many old and existing ahus use PSC motors and that EC motors are becoming more common? Maybe I'm mistaken but I believe you will still find centrifugal fan designs even with EC motors.

excellent video , even good for beginners.

THank KIUUUUU

I've never heard it called a FAHU before. I suppose it depends on the over all system but I usually call them MAU or DOAS these the former implies air is being taken out somewhere else

That run around system for heat recovery can also be used in place of that electric pre-heat coil for the 100% OSA/100%RA-EXH systems.

Im maitenance worker at a hotel; and i been operating an AHU for almost like a year now without knowing what "AHU" means.

Very interesting . I wanted to know how AHU work in case of fire in the building ?

major difference between FAHU and AHU are FAHU used fresh air take from atmosphere but heat exchange between return air to fresh by thermal wheel. AHU is recirculate air from return air to supply air.

ahu = air handling unit. fahu = filtered ahu

When you talk about the fans you say there are centrifugal type and electronically commutated. What a bizarre dichotomy considering they are describing two completely different parts. Plenty of centrifugal blowers have EC motors on them.

Hi Paul! Do airports use AHS that draw fresh air from outside? What about planes? Thanks!

Name of speaker ??

I rather have indoor air units on a floor someone instead of a ceiling you don’t want them breaking and falling on your head

my option is ahu is air handling unit but with f added its frequency ahu?????????????

Amazing thank you I'm new to the engineering department In a hospital. Very helpful

Why does my domestic ac heat unit run when it is turned off?
