- This is a basic HVAC video about "What is Air Handling Unit AHU in HVAC?/How AHU Works/ What is AHU? Part-1" in Urdu/Hindi language. It is basic learning information about the Air Handling Unit (AHU). It is also important for HVAC/MEP technical staff. Here sharing my experience and knowledge that will be helpful to learn & grow for Engineers & Technical staff.
I have explained in detail about AHU in HVAC i.e.
1. What is an Air Handling Unit?
2. Where AHU is used?
3. How AHU works?
4. Which are the main parts of AHU?

Another Good video !! Sir i shared this video in 3 MEP WhatsApp groups . Keep it up !Will be waiting for part 2.
Thank you dear
Super explain Thanks sir
Welcome
Bohat aala
Thanks dear Abdul Jabbar
Excellent explain keep making more vdo sty in tch frnd
Thanks

Excellent super excellent same like always
Thanks
Sir I am form India.....
Thank you
Welcome
Great
Thanks
Sir aap bahut acchha se explain karte h.🤗 Or aap sabhi qes ka reply bhi dete hai 🤔 thanks sir!
Question.( 01) Mixing chamber main air kaise aati hai?
Mera matlab kon deta hai mixing chamber main air....
Sir main CHILLAR and DG ko acchhi tarah se padkar kar BMS main kaam karna chahta hu.....
Please help me sir.......!
If you see the air flow diagram then understand. However, Return air and fresh air come in mixing chamber & mixed, afterward fan suck this air and supply through cooling coil as a supply air. This supply & return air taken from air conditioning room and fresh air taken from atmosphere
sir well explained the basic conspet of AHU...keep it up..i subscribed your channel for new upadate regarding Of Hvac...
Thanks
awesome
Thanks
Great video 👍👌
Thanks
Excellent 👌 sir .
Pura samajh aa gya.
Question ( 01). 100% fresh air q nhi dete hai ?
It depends on the condition
@@TanweerAhmed yadi meri marji ho to pura 100% bhi fresh air de sakte hai 🤔
Very good
Thanks
So beautiful brother 👍💞
Thanks
Thanks 👍
Welcome
@@TanweerAhmed sir ur very good explain
@@TanweerAhmed sir primary or secondary karte Ho details mein bataiye
Okay
Please make video on Air balancing, Exhaust air and supply air
Sure, Insha'Allah will prepare video
Heat recovery wheel ka zyada detail boliye please
Ok noted
السلام علیکم تنویر صاحب سراواٹر مست کے بارے میں بھی کچھ معلومات شیئر کرے
insha'Allah will prepare, now a days I am engaged in some personal works.
Nice video..Can you further explain the exhaust part? How to balance the return, fresh air and exhaust air? Waiting for your kind response. Thank you!
Ok I will....
Sir what's the criteria of Blower fan placement at return side or supply side?
What's the best place for bpower?
It decided by the equipment manufacturer
Aur bhi sir jada detail chws and chwr bhi connection hona chaye aur diagram detail hona mangta...
Ok insha'Allah
#sir please one video make on hvac chemicals dosing and desceling.
Ok
Bhai jaan kaun sa category selected kiya hai aap ne apne channel ka please bataiye 🙏
Science
Sir pressure sensors kun lagay jaty hain discharge pressure sensors or static pressure sensors main difference kia hy or kun laga ty hain
During designing the system, we have finalized parameters like velocity pressure and static pressure. For verification those parameters as per design, we use these types sensors in BMS
Static pressure of air of AHUs or fans is like head pressure of pump. If static pressure is ok then air to be delivered till end point.
Pressure is force per unit area. It means how much force is required in specific area for delivering the air or water.
Or ager temperature badhegi to humidity ghategi ki badhegi
If temperature increased then Relative humidity decrease
Dear sir cooling coil then heating coil using in AHU
But colling coil is ok for air cool
But why using heating coil?
In winter, you have a separate heating source instead of a chiller. Hot water circulates through the heating coil of the AHU, and then hot air is circulated in the desired space through AHU.
Ok sir thanks it's use only in winter

Sir HVAC system BOOK kn sa ha Urdu ma
I have no information about HVAC Urdu book
batter falay valv kam bataee
Butterfly valve ON / OFF Kay lieay istamal hota hay. Oar is ki thickness kam hotey hay.

Hi

Sir aapka jo psychrometric chart wala video tha wo aapne delete kar diya kya mere ko study karna tha
It is available in my HVAC playlist

th-cam.com/video/YfsZZJaCjM8/w-d-xo.html
@@TanweerAhmed thank you so much sir
Sir kya aap apna whatsaap number de sakte hai agar aap chahe to
Sir temperature kam hoga to humidity ghategi ya badhegi
If ambient temperature down in morning or evening then Relative humidity increased. If ambient temperature increase in noon then relative humidity decrease.
@@TanweerAhmed thank you sir
It's means relative humidity depends upon ambient temperature..
@@gulabrbbani2261 This is example of ambient temperature as per graph showing research
@@gulabrbbani2261 watch my psychrometric chart part-1 for basic concepts of humidity, absolute humidity, relative humidity, temperature etc.
Sir apka whatsApp number mil sakta hai
