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.
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?
from 9:27 - 9: 57 you shared a schematic where the AHU is connected to several FCUs.If the AHU is already conditioning the air why do i need to again condition it with separate FCUs for each room?
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...
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
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!
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.
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.
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
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.
Quick question: If every room contains its own FCU that controls the temp, then what is the point of the coils in the AHU which are also heating and cooling the air?
Bodega Mouse the FCU's are not sized to condition all the air. imagine in peak winter/summer when the temperature of the outside air is extremely low/high. the little coil in the FCU can't cope, so the main AHU will. There are times in the year when the air temp outside is within setpoint limits so the AHU could will not run, then it is up to the local FCU to decide if it needs htg/clg
You are correct that the AHU will bring the fresh air in and bring it to a usable temperature. The AHU is essentially there to supply fresh air to the building to keep the occupants healthy. The FCU's are usually a ways away from the AHU and will need to bring the supply air to the final temperature to keep the occupants comfortable. This means that the AHU's primary job is to bring in fresh and temper it for branch units like FCU's.
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
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?

Hello, we would like to translate this video into Russian and use link on our web site. Please let me know if it's possible
great video some times we need to see it to understand it

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
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
You've changed so many people's worlds mate.
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.
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?
what a comprehensive explanation that won my heart
from 9:27 - 9: 57 you shared a schematic where the AHU is connected to several FCUs.If the AHU is already conditioning the air why do i need to again condition it with separate FCUs for each room?
Perhaps south side of building is in sun, north side is in shade. The rooms have different heating and cooling requirements.
First of all Thanks alot for giving such kind of technical videos.
Kindly keep these efforts up
Paul. You are our greatest teacher.
Thanks!
Thank you
my god!! excellent visual representation along with narration. Thank you so much.
This helped me so much! Thank you

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
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.
Any video explaining the modes of operation in chillers?
Off, stand by, crankcase heater thermostat off .
Quick question: If every room contains its own FCU that controls the temp, then what is the point of the coils in the AHU which are also heating and cooling the air?
Bodega Mouse the FCU's are not sized to condition all the air. imagine in peak winter/summer when the temperature of the outside air is extremely low/high. the little coil in the FCU can't cope, so the main AHU will. There are times in the year when the air temp outside is within setpoint limits so the AHU could will not run, then it is up to the local FCU to decide if it needs htg/clg
Finally I found an answer 😅

The FCU's are usually a ways away from the AHU and will need to bring the supply air to the final temperature to keep the occupants comfortable. This means that the AHU's primary job is to bring in fresh and temper it for branch units like FCU's.
Hi Paul Very well explained..just one doubt, why their is a gap between fcu filter and fresh air supply..
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
Excellent vid, very interesting
Thank you for this video!!!!
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
No
pure cleaning simple English used good explanation thanks from a Safety officer
I cannot thank you enough :) Thank you so much :)
Great video
Hi just had a small doubt. The AHU which supply the fresh air,will this air be cooled or at normal temperature?
Thank you so much! Your explaination is extremely useful and wonderful.
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?
