Excellent explanation, have just read about 4 books on Air conditioning and you have explained FCU's far more clearly in this 13 minute video. Hat's off to you sir!
Sir you are the best , i was taken 9 months to learn this system but after in this period unable to understand the whole system how it works but your 13 minutes video is enough to teach how it actually fcu working, thankyou so much for your valuable information for us.
Really appreciate the work u do to explain each system with the help on 3d models . It makes understanding so simple. Giving real time images and pictures also helps. I will surely donate and promote you .
Nice to see engineer stand/point of design inside of most office spaces. In the US most units also have FCU with newer FD motors available in most applications.
I just got into my career field as an apprentice engineer. I just want to say thank you for this video. It's helping me understand these units so much more.
Ohh mannn, this helps me lot than you think. Working on my final exam project n I was worried about Air Distribution System because of small space between ceiling and roof
What is the difference b/w FCU, Fan Powered Terminal Units, and FVAV units? I am familiar with the FCU, but I haven't been able to find much information on the others. Your videos are really helpful, and I appreciate the time you take to make them. The graphics are great for a visual learner like myself. Thank you!
VAVs (variable air volume) always remain on and will adjust the air flow to the demand. This allows for pretty good dehumidification and fresh air supply at low fan speeds. Fan coils usually act the same as a central system turning on and off when the thermostat calls for it. Terminal units specialize in supplying fresh air and quite often don't have components to cool or heat the air at all. Sometimes they will have integrated heat (hydronic or electric) to keep the air warm enough to not freeze in the ducts.
Fantastic videos I've recently started to work in building maintenance services and I think I can learn a lot of stuff from this channel keep up the good work thank you!
Amazing videos I really appreciate it, just have one question why the air supply duct is not connected to the fan coil unit ? I don’t think this was addressed in the video just mentioned
Hai....Gave a good explanation about the topic with real time photos and videos...Can you please upload videos about the installation procedures of ductwork and accessories based on the sitedrawings...
What are the advantages and disadvantages of a FCU over a VAV system? Can an air handler have VAVs and FCUs together hooked up to it? If so, why would you use one instead of the other? I'm new to this industry and I've learned so much from your videos. Thanks
- The advantage of a FCU system is that you need much less space for the duct work and AHU's. - The advantage of a VAV system is that its easier to design a silent system especially if the units need to be installed in the occupied space, also less components = less maintenance. - Yes technically you can combine VAV boxes and FCU's in one system but you will need to use CAV/VAV dampers for zones that require a minimum fresh air flow to keep the system balanced (You will rarely see this though). - You need to consider all the advantages and disadvantages for the specific building when designing a system, one is not better than the other.
Thanks Paul! Question: is this fan coil same came which you’d shown in AHU video? I am trying to understand if it is a stand alone unit or part of AHU. Essentially the location and where it fits in HVAC system.
Thank you, Paul! I have an assignment where we have to do HVAC systems for a complex apartment building. Can you please do a simple Revit tutorial on how to do an All-Water Fan Coil system that has its own Fan Coil Unit inside the apartment (in a AC closet) that is connected to the cooling tower on the roof? Thank you so much.
Very good explanation !. Thanks, I undestand much more now in my condo unit. High rise building Bulkheads tend to have a lot of dust inside the bulkheads as a result of fresh air from the main duct into the bulkhead space. It is unclear why my unit has this air pushed into this very large false ceiling void in my condo unit and why it is not directly placed in front of my Heating/cooling coil or connected to it. My 10 Year old highrise has lots of dust buildup inside the false ceiling void. Clearly as you say, it is to have some air mixture from the unit rooms into the ceiling grate and mix with the fresh air. Not a very good engineering design if you ask me. Maybe the false ceiling should be smaller or maybe the Fan source should have appropriate filters to manage the dust and hopefully would resolve this. thanks again
Superb video. Thank you! One question, can you explain why the inlet air to the FCU has a "open gap" instead of traveling inside ductwork the entire way?
this help me so much to learn about FCU, btw can i remake this videos and make the explanation with my country languages ? i think it will be help people in my country to understand about this FCU with explanation in my languages thankyou
Is there, or was there older technology in a Dual Temp System that created a blended water temperature in the plant system piping before it goes out to the FCU or UV...something like a typical kitchen faucet? Great videos. They are very helpful. Keep up the good work! Thanks
I’m not sure about dual water temp systems (usually only one temp runs at a time) but most (if not all) heating systems I’ve seen have a modulating valve to mix some of the heated water with the colder return water.
At around 1:37: This fresh air is directed into the back side, the inlet, of the fan coil unit but this branch isn’t usually directly connected to the unit, there is a gap between the two. There is a reason for that, which we’ll look at later. So why isn't it connected then?

You've changed so many people's worlds mate.
Getting me through my degree, one video at a time! Thanks Paul!
What degree is it that you’re working towards?
@@tidurphious mech i think
what a comprehensive explanation that won my heart
Really appreciate the work u do to explain each system with the help on 3d models . It makes understanding so simple. Giving real time images and pictures also helps. I will surely donate and promote you .
We have FCUs and my job! Thanks to you I am starting to understand how it works!
Nice to see engineer stand/point of design inside of most office spaces. In the US most units also have FCU with newer FD motors available in most applications.
Finally found a clear and informative explanation on proper English. Thank you very much
I just got into my career field as an apprentice engineer. I just want to say thank you for this video. It's helping me understand these units so much more.
Glad it's helping, Mike.
Paul. You are our greatest teacher.
You are as clear as they come -kudos !
my god!! excellent visual representation along with narration. Thank you so much.

Great video! This has been very helpful. Thank you.
very well executed video mate
Thank a million my grateful mentor!
Hi Paul Very well explained..just one doubt, why their is a gap between fcu filter and fresh air supply..
Best video I've seen explaining this. Thanks!
What are the advantages and disadvantages of a FCU over a VAV system?
Can an air handler have VAVs and FCUs together hooked up to it? If so, why would you use one instead of the other?

It's worth covering in a video, ill add it to the list
- The advantage of a FCU system is that you need much less space for the duct work and AHU's.
- The advantage of a VAV system is that its easier to design a silent system especially if the units need to be installed in the occupied space, also less components = less maintenance.
- Yes technically you can combine VAV boxes and FCU's in one system but you will need to use CAV/VAV dampers for zones that require a minimum fresh air flow to keep the system balanced (You will rarely see this though).
- You need to consider all the advantages and disadvantages for the specific building when designing a system, one is not better than the other.
Perfect explanation
Iam without doubt joining your channel

pure cleaning simple English used good explanation thanks from a Safety officer
Excellent Video! Keep it up!
Great video, Many thanks!
Very good video , Thanks
This is very helpful.
Excellent Video.....!!
Very nice presentation.... thanku... I would like to know how the temperature is controlling here?
Hi just had a small doubt. The AHU which supply the fresh air,will this air be cooled or at normal temperature?
These are some of the best and most concise videos I've found on HVAC. Any chance you can do one about VRF and Dedicated Outside Air systems?
New VRF unit video here:➡️ th-cam.com/video/4i1XgcP1tmw/w-d-xo.html

Very nice explanation sir .
Thank you sir
Excellent. Can you do a compare video between FCU, DX system and VAV. Would be great if you could extend into the relative efficiency of each system.
EXPECTING THE SAME ASAP
Very Nice And Very Good Thank You
Thank you very much this video helped me very but I would like to suggest you please also type the name of elements .
This helped me a lot. Thank You so much
This vedio helps to understand easily ,thank you
that was awesome.... it's really helpful..thank you so much...
All video about HVAC are intereste
plz give details installtion procedure of AHU,RTU,FCU,and cooling tower and duct work
Excellent vid, very interesting
I cannot thank you enough :) Thank you so much :)

There is a reason for that, which we’ll look at later. So why isn't it connected then?
What happens when you only need cooling? Is there a two way valve shutting off the hot water supply and vice Cerda if you need heating?
Thanks sir we need explanation Fcu - electrical controller box with BMS
