Excellent video! I want to make an egg incubator, for which I need to know, how to calculate the equipment (fan) requirement for the incubator. Really appreciate, if you could help me in this regard.
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
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
Ek site hai usme package ac laga hua hai aur duct se connect hai aur usme diffuser laga hua hai to usme anemometer se kaise air balance kre ge pls baataao bro
Sir humre yaha ak AHU h jiska model number DM2N1319 Serial number 1409118 Air flow 6318L/S Motor capacity 11kw. Ye kitne to ton ka h please reply with solution.. please
Velocity measuring instruments k bina velocity kaise measure kar sakte....anemo meter, pitot tube , hot wire anemometer , capture hood type anemometer..inme se koi sa v instruments hona chahiye apke pass
FPM= Foot per minute FPM (Foot per minute) velocity ki unit hai jise measure krne k liye anemometer ka use krte hai.... practically kaise reading lete hai ispe video Kal ane wali hai..
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??
Today i got best informative channel to know about HVAC

Sir please tell about how to deside the static pressure of ahu
Sir iam ac department m job krta hu .. from AIIMS jodhpur 🙏
Are bhai tmse baat krni h ..plz mereko contact kro mai bhi AC department mai hu
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.
You can take measurements whatever filter is

Ok
@@HVACWorld Really appreciate!
I think discharge flow will be high compared suction Flow
Yes
sir apart from theory hvac calculation part topics kya kya hotha hein sir for mep technician in hvac
Sir,agar filter different size ka hua to @hvacworld
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
The device to check the velocity should be kept back or front of the filter?
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
@@HVACWorld no problem... Your work is amazing.. Lots of skills and knowledge we r getting.. We r waiting for ur many more videos..
What are the books that you refer to get the complete knowledge of HVAC??
Basic of refrigeration and AC by Mr.Annanthnarain is the best book
Chacha kitni area mai kitne capacity ka ahu laga sakte hai??
AHU m deferential pressure switch or pressure switch with tubing kese krte h or location kya rhti h

Sir Diffuser Collar & Grill Collar me se kitna cfm nikal raha hai wo kaise calculation karna hai.
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 👍

Sir humre yaha ak AHU h jiska model number DM2N1319
Serial number 1409118
Air flow 6318L/S
Motor capacity 11kw.
Ye kitne to ton ka h please reply with solution.. please
33.5 TR approx.
@@HVACWorld thank you sir.
But please breif me
Sir give me formula
Will explain in next #askquestion session...plz watch #askquestion-1 and share to your friends also

Thanks
Sir iska calculation step by step karke dikhaoan sir
Hello Kai se pata knre ki AHU kit ne TR Ka hai
No multiplying factor...? I think there should be multiplying factor for Anaemometer..like 10 , 20..
Multiplication factor used where least count of anemometer is 10 ft/min. We are using anemometer whose least count is 1 ft/min

Sir aapne one filter area galat liya hua

Velocity calculate krte hue Anemometer k reading m multiplying factor s multiply nhi kia apne???
Anemo meter na hoto velocity measure kese kare??
Velocity measuring instruments k bina velocity kaise measure kar sakte....anemo meter, pitot tube , hot wire anemometer , capture hood type anemometer..inme se koi sa v instruments hona chahiye apke pass

Sorry friend....mai personal kaam ke bzy tha...ab continue video upload krta rhunga...
What is 4 ?
Sir practical video nhi aya apka!! Pls
Sorry friend....mai personal kaam ke bzy tha...ab continue video upload krta rhunga...
Fpm Kia hota h or kesy measure kartey h
FPM= Foot per minute
FPM (Foot per minute) velocity ki unit hai jise measure krne k liye anemometer ka use krte hai.... practically kaise reading lete hai ispe video Kal ane wali hai..
@@HVACWorld ok sir please thanks
My pleasure 😊
why you use 4 ???it is for 4 filter..but why we use 4 because already we make average of all 4 filter .
Your name sir
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??
1 meter square = 10.76 ft square...you can cross check it anywhere..either in Google or in books
@@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
Very good.... don't trust anyone either me or Google.. first do self cross check
yes 10.76 sq ft
Sahi Uchcharon vi nehi ata hay spko
Thanks for your feedback
AHU ka tr kaise nikalte hai
400 cfm =01tr
Shailendra ji 400 CFM =1 Tr ye thumb rule hai.... Actual TR nikalne ka formula hai...water or air dono side se nikala ja skta hai...
Area calculations not to clear me
Blowre ke bad coil ati hai
FCU me hota hai aisa....AHU me filter k baad coil or uske baad blower hota hai
.61x.61x 10.76 how much bro?
Mention dimensions also...like meter/CM/Inch
10 ka gura kyo karti hi
