This was incredibly hard to decipher what he's saying. But it's still the most informative video that I've watched Don this topic. Well done. Consider adding subtitles.
Exhaust air 275cfm, we need 1800 cfm, return air 1600cfm, and fresh air 200 cfm, my question is that, is it possible to maintain provided data. So please clarify me? Thanks
I got tonnage and cfm through cool load Calculation as you shown and i have to choose best place to keep fcu and how can i divide the cfm in a hall and after divide if i want to use grill how can i design plenium box for grill and airflow
Hello checked 12.5 ton package unit for PM,customer complained unit air vents to noisy,checked all vents in the office found some vents getting no air & some pushing so much air that when you close the manual louver in the vents it makes load windy noise like air wants to ecsape,i opened the pulley to where it wont affect pressures & tempto lower rpm but still not much different,i believe 1st they installed bigger size unit 2nd they never connected ducts for some areas cause vent are fully open but no air so thats air balancing issue as well,can any tech please give me advice how to solve this air problem i need to get back to owner. by the way not all vent are same size 15x15 & 12x8 are the air vents sizes trying to give much info as possible
There might be problem with proper air Balancing. And need to check if all the duct are connected to the unit. Before that you need to find the required airflow of each outlet Diffuser or grill and the total AirFlow. The velocity is increasing due to closing of manual damper. Step 1 check first if all the duct work is connected to the unit Step 2 Balance the air flow. And if the unit is already oversized then you might have issue.
How will a particular duct send specified amount of air to a particular room? As d outlet from our condenser is one .. that is 1800 is coming out of it how will it sense how much I have to send bedroom dinning room n others as they are not same values
Hi sir thanks for u sharing knowledge please clarify me what standard basis you are calculating exhaust air flow for kitchen and toilet u are give supply example kitchen 150 cfm taking exhaust 200 u are increased 25 % extra amount of supply air duct and toilet 50 cfm supply taking exhaust 75 cfm here u r increased 34 % so clear me how much percentage % we should increase exhaust as per Aahrae standard for pressure different
Hi sir, when you balancing an extract system especially in toilet using micromanometer and hood which area you consider in calculating the vol. Flow rate?
Thank you and I have a question for you. For our office I got to get the Air Balancing done because there are different temperatures in different areas of the same floor. But I don't have the diagrams of the AHU Ducting since the land lord also doesn't have it. So on what basis can I get the Air Balancing done? Can i Calculate the total CFM and get distribute it equally on the floor?? Please suggest
Assalamualaikum sirji kitne area may kitna cfm divide hona chahiyeh kaise pata chaleingeh , Example aapne bataya layout may ki ek room may 500.cfm kaisay patah ya calculate malum hoga ki itnahi chahiyeh
faizan zafar there is equation for size calculation for louvers and grills. Usually selection of louvers and grills are done by suppliers catalog. In that they will provide, for this much CFM, this much size of louvers, grills, diffusers, etc is required.
This seems like it would have been an excellent video but to hard to follow with both languages. Maybe do separate videos in separate languages. Appreciate the effort though

Hi, just want to know. What about the loss of supply air? Full supply air cannot return back. Do we need to increase fresh air in such case?

When you perform the calculation. Saperat the room by zoning them. By doing that you will get individual airflow.

At the time of Purchase sizing the DUCT is Sized accordingly based on the AirFlow Requirirement.

This are the examples to understand, for kitchen use ASHARE and IMC standards.
Use ASHRAE 62 for exhaust and Ventilation requirements
