Sir,i saw your return only air terminals it has no ducting going to ac unit,is it possible also to makr return duct connectig thise return diffuser and tap to ac unit?
Hi Mr Syed, I'm Xavier and now I am currently doing laboratory building project where i need to key in the OA requirement. However, I can't use the ASHRAE std as it is neither a college lab nor a science lab for education. The labs are mostly filled with fume hoods and hence re-circulation of air in the room space is not allowed. My question is, how can I determine my OA requirement values? Do I base on the total exhaust of the lab room?
Excellent sir ,very useful tutorial ,you made it very easy and sir please make some videos on chilled water pump head calculation, and ESP calculation.thanks a lot
I made a video related to duct traverse calculation (for air balancing) few months ago. Kindly go to my channel and see tutorial#52. I hope that would be helpful for you :)
Very simple and easy way of explaining!!!
Keep up the good work👍

Excellent sir,can share drawing for reference and tutorial
Hi sir, if i use cfm=(airchange x volume)/60 formula to get the cfm is it different with this method? Which is more recomended?
how about return air quntity. is same as fresh air quntity?
Excellent sir ,very useful tutorial ,you made it very easy and sir please make some videos on chilled water pump head calculation, and ESP calculation.thanks a lot
Yeah sure. I will make it soon :)
can you explain..how to calculate the exhaust air for the FAHU
very helpfull..thank you
Nice video. By the way How to supply little TFA like 15 CFM to specific room? Thank you!
Sir do you have a tutorial for getting the static pressure requirement of fresh air fan? thanks
Not exactly for fresh air fan but You can find static pressure calculation tutorial using Ashrae duct fitting database software on my channel
hi bro ur tutorials are very useful to us.
please make video of air flow balancing calculation in xl sheet.

Assalamalikum...Very well explained kindly make video on DOAS unit, ventilation fan, supply fan and Ventilation calculation by using HAP Software
aslam o alekum sir please put also this exel sheat here in link sir
What is TFA sir
Total fresh air
But how to calculate TFA sir
Volume of room x air change per hour=TFA(CMH)
👍🏿
Can’t even understand him. What’s the use?
cad file please
Email address??
