Very good explanation

[@anthonysalve4023]

1. Please/show explain this heating & humidification in AHU. 2. Cooling & dehumidication on psychromatic chart.

[@waquarahmad8601]

First of all you are doing great job!!
We appreciate your greater efforts.
My question is below.
How do we decide or calculate the quantity of steam or water to be added to the AHU to achieve the desired humidity level in the space?
Can you please elaborate in the next video.
Or anyone there who can explain this?
Thank you in advance!

[@bilalpurpraveenkumar8257]

By measuring the Return Air temperature and supply (cooling coil) air temperature of the AHU we measure that

[@user-du2kr3fu7h]

When it is warmer outside, the air holds more water vapour, and when it is cooler outside, the air does not retain as much water vapour. This explains why summers are hot and humid, while winters are frigid and dry. Therefore, the summer season has more humidity than other seasons. don't share wrong information.

[@abbasmaskati5339]

Nice very informative
Sir can you please make video on design of hospital operation theater

[@akhilihka]

very well done

[@syedahsanbukhari4400]

Awesome lecture

[@sachinkp4504]

Well explained sir

[@rituthakur307]

I have doubt if we remove moisture/water by cooling coil.. then why RH increase, as u said rh means amount of water vapour in air...

[@HVACWorld]

Moisture is continuously adding in environment.. because everyone second water vapourisatiin takes place....our body also relases water from our body...and light and computer these are the elemt of latent heat which continuously adding moisture..... because of these every time RH increases which have to put down up to human comfort

[@Shamiyusif]

HVAC World computer and light can add only sensible heat not latent heat .

[@kantmarch1]

You are saying right. He seems to tell wrong

[@aymankhan9001]

First of all understand dbt wbt ....latent heat .humidiity..
How much water present in air then is also called relative humidity rh...
Dbt and wbt measure by psycrometer...there rr two therometer installed in one equipment system...if the relative humidity is more then we fell uncomfortable why......because due to present of water to more in our surrounding

[@Nilesh_Shinde23]

Right

[@nimishsingh172]

sir aap mahaan hai

[@user-hw5kn4gl4k]

thanks sir for this video , can RH control possible by ductable units

[@HVACWorld]

Yes it is possible up to certain limit

[@user-ky5ub5yc5e]

Thaku

[@subhadipmohapatra9197]

Hi Sir,
Excellent Explaination. Thank you so much. Can you explain how to calculate Heater KW ?? I have an application where I need to maintain RH @45%.
Thanx in advance

[@bujjamma6669]

Professional explained 👌👌👌👌👌👌👌👌👌👌💗

[@irfankarim8400]

Hi bro i need your help if we heating coil in AHU can we electric duct heater we can install for the prayer room or kitchen and why

[@HVACWorld]

Can you please clarify your question. Sorry I didn't get that

[@mohammedkarim4790]

FAHU york ka hai aur labs me use hota hai jiska return air atmosphere me exhaust karte hai reuse nahi karte

[@funnymemers3232]

Mast video h sir

[@SudhirKumar-fh4eh]

Sir namste coil aur fan ki distance kaise karte hai

[@ershaikhfahad2816]

Sir in sea side luxury hotel here ahu has 4 coil inlet and 4 coil outlet system means 2 chilled water inlet and 2 chilled water outlet and and remaining coils has normal water circulation in closed loop why this is provide after the cooling coil is this the Same dehumidification control via reheat system

[@HVACWorld]

Because high humidity near sea area.....coil has to remove moisture from air....and balanced coil having normal or hot water circulation is provided to main RH in air conditioning area.
Because high level of humidity can not be maintained by dehumidication and cooling. There should be reheat process

[@abdulkidwai5945]

Sir plz make video on manual calculation

[@MandeepSingh-el6un]

Sir plz make video on "calculation of HWG capacity for maintaining RH in OT"
AND "calculation of HWG capacity for winter heating in existing Chiller circuit"

[@ATIFKHAN-mz4fp]

Good morning sir for year around air conditioning system we apply all above process to control RH

[@sohailqureshi503]

Salam sir h r u sir hmare pass airwash system h usme Sirf water spray k sath air follow hti h duck m to RH control nai hri wese pora saal ase hi chlta h system RH kbi 45 kbi 55 show krta

[@irfankarim8400]

If ahu have heating coil and in duct we can install electric duct heater
Is it possible ?

[@HVACWorld]

Yes you can but If AHU has heating coil only why you need to add extra heating source . You can install heater in duct when you have cooling coil

[@rockypundir2278]

Bhai apnea concept m today confuse Kar diya Hai, agar wer bulb and dry bulb k bech ka diffence Jada h toh humidity down hogi ya increase hogi ?

[@HVACWorld]

RH decrease hogi.... Humidity constant rahega until unless moisture add na ho.

[@moonshiekh1100]

Bhai ek baat samjh nhj ayi mujhe summer me toh temp jayda hita h Humility jayda hoti h which means ki water vapor jayda h air me isliye garmiyon me chip chipa paseena feel hota h humidity jayda hoti h just opposite in winner me humidity water vapor kam hota h isliye winter me hamri skin dry hota h
But chat me just opposite show kar rha h garmi me kam nd winter me jayda dekga rha h
Samjh nhi aya ye kya chakkar h ???

[@HVACWorld]

Bhai summer me humidity kam hoti h

[@siddheshparab8302]

Lekin summer mein 20% RH hain, aur cooling & dehumidification ke baad toh RH aur kam hona chahiye ?

[@moonsheikh7117]

Are 44 dbt
Wbt 23
Gap jayda h isliye rh 20% kam h
Summer me cooling krenge
Jab cool hoga 44 se ye 24 ke pass pass aywga means dbt wbt me gap kam ho gya automatically RH 20 se 50 t0 60 phunch jayega
Samjh gya logic
Gap jayda toh rh kam
Gap kam toh rh jayda
Iss logic se samjho

[@virendrapanwar312]

Sir data dijiye kitne CFM mai kitne kw ka heater lagaye aur pan humidifier kitne capacity ka lagaye

[@mohdarman8149]

Pressure relief valves kiya kaam hai HVAC me kahan fiting hote hai

[@rajeevsrivastava2940]

I am facing rh issues in our clean room .
Not achieved rh

[@vikashkumarpandey8317]

Please review your RH value for winter and summer.

[@HVACWorld]

Ok

[@subhashishbhattacharjee4993]

Sir dry bulb aur wet bulb k liye koi video banaya hai kya?

[@shabbirali4580]

Is every AHU have enbuild humidifier or dehumidifier.
In winter we don't need humidifier to control RH, but if it's there in AHU, how to stop humidifier to work in winter.

[@HVACWorld]

AHU is also known as dehumidifier....AHU doesn't have inbuilt humidifier. We have to provide humidifier based on requirements or design

[@shabazkhan282]

Sir ahu ki wairing kaise karte hai usper video banaiye please

[@asifjutt8824]

👍

[@nehal3749]

11:42 agar de humidification hogaya to after coil rh kaise increase hoga aur humidity kaise increase hojayega??

[@HVACWorld]

Actually jab air cooling coil se cooled hoti h to uska temperature saturation temperature k pass laya jata h or aap psychometric chart pe dekhoge k saturation line pe air ki RH 100% hoti h... Saturation curve pe air ko lane se hi wo dew point ki trf jati h or jisse k Condensation hota h or air dehumidifie hoti h
...jaise hi coil se aage air nikalti h wo room se heat leti h jisse ke uska RH kam ho jata h ...is trh se RH maintain hoti h cooling and dehumidification k case me

[@jamsheerali7229]

Steam type built in humidifier, is control both humidification and de humidification ?

[@irfankarim8400]

I have both cooling coil & heating coil in ahu and humidifer
Can we add electric heater in duct
Tell me

[@HVACWorld]

If your Heating coil se sufficient to maintain the RH inside the room then it is not required to add heater in duct...if you want only heating inside room in winter season and your heating coil capacity is not designed for heating then you can add heater inside duct and use both coil and heater for comfortable heating inside the room...make sure your CHW supply should of in OFF condition

[@irfankarim8400]

Thank you

[@arunkumar-yl6yt]

How will the control system for rh control work

[@bhivajibargaje4290]

I have installed Humidifier and dehumidifier at my company....now days I am not able to increase the humidity... please

u said we use moisture in summer!!!! how funny

[@HVACWorld]

Will answer you by making video deticated for your questions

[@ramsinghtomar7943]

Hello Sir please tell us about heater selection how to calculate heater kw

[@BittuSingh-rw1kr]

Moisture to condense ho gya hai cooling coil ke pass, phirr room me 90% moisture kaise rahegi

[@HVACWorld]

Room me nahi rhegi.... supply air pe rhti h...kyu k coil DBT ko WBT k near about kar deta h

[@shihasvkd]

Can you please make videos in English ?
