Sir You said 7.2 instead of 7.5
And if 7.5 CFM/person is correct then I think the no 3 formula need to be correct...if am wrong please correct me
@@abulfaraz66877.5 value in 3rd formula is ok
Assalamualaikum sir ham duct ka area ko nikalne ki kya jaroorat padti hai aur iska Kya kaam padtaa hai.
1. Duct area calculate karna zaroori hota hai taake duct sheet ki quantity ka andaza lagaya ja sake.
2. Duct area calculate karna airflow ko maintain karne ke liye bhi important hota hai.
We can use this formula to select fcu for a room?
FCU selects cooling/heating load capacity and then calculates airflow accordingly. Alone air ventilation formula isn't sufficient to select an FCU (Fan Coil Unit) for a room due to various factors.
How yo know about grill size
Basic term is airflow (CFM) for grill and then size with different factors like NC, Velocity pressure, Neg. Static pressure, etc,
Sir electrical services ki video bnaye..
Ok noted
Sir share the table for 100 percent ventilation for a storage hall
I did not find any table having ACH for storage hall, Ashrae Table 6.1 shares only cfm per ft2, when we calculate CFM using only this total number of CFM value comes very low which is not acceptable for very large hall
Let me check
Sir Air change karney ka method kya hoga usually We do not open door in AC room
If you have single split AC then you should add through small fan or window etc. If supply air is from AHU then fresh air will be added there.
Sir Very informative and to the point video
Any wahstap number through which we can reach you?
Thank you
