Cfm is the unit of air flow. Matlab 1 minute me hmara ahu ya fcu etc kitna hea phek raha hai.

[@vinayaknehe379]

thanks sir ji

[@HVACWorld]

I used 4 here For finding total area of All 4 filters.....

[@susheelrajput4312]

Sir please tell about how to deside the static pressure of ahu

[@brijeshkumar7633]

Is it correct way to find CFM on HEPA filters or LAF filters. Or the best way to find is how you explained in the video.

[@HVACWorld]

You can take measurements whatever filter is

[@shahzadmajahiri4690]

Iske super jaldi video banaiye

[@gauravdixit3537]

dear sir, kisi kisi AHU me 10% fresh air jate he vaki recycle hote he tab inlet aur out let air pressure me difference hoga

[@IrfanKhan-yb5vt]

Pahle design CFM check karenge aur freshair se check karenge ki utna design CFM mil raha hai ki nhi uske bad age saphly CFM check karenge 👍

[@Shiv.kumar92]

I think discharge flow will be high compared suction Flow

[@HVACWorld]

Yes

Chacha kitni area mai kitne capacity ka ahu laga sakte hai??

[@k.p.pranav7356]

The device to check the velocity should be kept back or front of the filter?

[@HVACWorld]

Anemometer should be kept back of the filter from where Return Air is coming... in this week you will get the video of Live demonstration of CFM calculation of AHU...sorry for the delay because of personal issue

[@k.p.pranav7356]

@@HVACWorld no problem... Your work is amazing.. Lots of skills and knowledge we r getting.. We r waiting for ur many more videos..

[@sheikhirfan65]

What are the books that you refer to get the complete knowledge of HVAC??

[@raginisahu5854]

Basic of refrigeration and AC by Mr.Annanthnarain is the best book

AHU m deferential pressure switch or pressure switch with tubing kese krte h or location kya rhti h

[@HVACWorld]

Sir DP Switch duct k End me lagate hai....DP switch ki positive bwali tube duct k andar dalte hai or negative wali tube bahar nikalte hai jisse k duct or room key andar ka pressure difference measure ho sake fir ye signal VFD ko jata hai jisse VFD frequency ko Kam ya zyada krta hai jisse AHU ki speed Kam ya zyada hoti hai

[@satyamjaiswal5561]

No multiplying factor...? I think there should be multiplying factor for Anaemometer..like 10 , 20..

[@HVACWorld]

Multiplication factor used where least count of anemometer is 10 ft/min. We are using anemometer whose least count is 1 ft/min

Sir, in calculation when we convert Sq meter to foot in Google.. We r getting answer 6.565 Sq foot... So which is correct the way your calculation or frm Google??

[@HVACWorld]

1 meter square = 10.76 ft square...you can cross check it anywhere..either in Google or in books

[@k.p.pranav7356]

@@HVACWorld Okay sir U r rite 1 sq meter = 10.76 sq ft... then for 0.61 sq meter = (0.6x10.76)= 6.565 sq ft

[@HVACWorld]

Very good.... don't trust anyone either me or Google.. first do self cross check

[@mohammedsaadsaqibareeba9889]

yes 10.76 sq ft

Cfm ka matlab? 1 feet lambe 1 feet chude, 1 feet Hight ke hwa se bhare box se 1 minute me jo koi pump hwa nikal de raha hai ya bhar de raha hai wah uska 1 cfm hota hai. Aasan bolchal ki bhasha me.
