The best explanation so far on RUclips excellent teaching methods fantastic analogy. Please can you make video How to troubleshoot AHU using real world example by utilising Psychrometric chart?
Sir! In the process of cooling with dehumidification, dehumidification would not start untill DBT reaches to Dew Point temperature which is 15C in this example. So shouldn't there be first straight horizontal line and then an inclined line from 15C DBT to 14C DBT?
Thank you very much. Your classes are good. Expecting videos on basic of thermodynamics especially the concept of entropy which is very much confusing.
Sir u please make a video on heating and humidification and dehumidification and that too with the help of an example... because it makes us vry easy to understand
Hello Sir, My question is in the process of Cooling with Dehumidification, we know Ms decreases since cooling occur, But does Mv also decreases in this process?, If yes, then why not the increase in Relative Humidity (due to decrease in Ms ) gets nullify (due to decrease in Mv) . I Need to understand How Relative Humidity only Increases although both Mv and Ms decreases in Cooling with Dehumidification process.
Good Effort sir. Thanks a lot. It's really helpful. Question: If water vapour is present in superheated state in air then why do we not feel excessive heat??
There are two reasons 1) If Vapor is in superheated state, it means that the air is unsaturated. If the Vapor is superheated, It carries lesser pressure and it does not have enough mole fraction of Quantity to have a complete effect on humans. 2) The quantity of water vapor in air is around 0.5 percent on aggregate
Very nice and good explanation sir but when explaining about dew temperature you haven't mentioned that we are decreasing temp but we are keeping the pressure constant. Thank you so much for the video👍
your explanation is superb sir thanks for making the video its a very much helpful video sir . can you make the video for summer air conditioning system
Good explanation sir ... my question is why does water evaporate in evaporative cooler ( what is the reference of this property in psychrometric chart ? ) ... Cause water boiling point in 1 atm pressure is 100 C . Is that mean we decrease pressure inside evaporative cooling chamber ?? Thanks ...
Hello Sir, its indeed a very good explanation. But cooling with Dehumidification - wont the end point after the cooling will have almost 99.0% of RH as it will constantly condensate when the temp is lower and keep the mass of water vapor at saturation value of the water vapor? Also the sensible cooling line will be vertical until it reaches the Dew Point temp then it follows the curve of dew point temp?
Sir,after coil dbt and wet bulb temp are low and Rh is approx 100 percent, means as per your example after ac ia 100 percent ,but human comfort is 50 percent ,pls clear I m little bit confused
no one explain like this .thank you so much sir. i would like to know that range of humidity of human comfort, hot and dry humidity range and hot and humid of humidity range. sir please comment the range of those 3 humidity.
No no listen properly in case of perfect humidification I might have shown straight line....but in case of cooling with dehumidification the line will be inclined heading towards lower temp. As you have said
One of the best teachers of the psychrometric processes hands down! Fundamentally sound.
Thanks 👍
आपके जैसे teacher मुझे स्कूल में मिल जाते तोह आज में scientist होता😁🇮🇳😀
Awesome explanation sir
sir do more lectures on psychometric..u teach in very simple manner so understanding
Aaj tak samaj me nahi aaya tha ab
Dono process samajh as gye h
Saath hi air conditioning ka concept bhi woh Pani wala
How easily you explain about these doubtful topics ! Really i was searching this type of channel.
This clip really cleared my doubt. Thank you Sir for the detailed explanation of the concept
Nicely explained....can understand the concept easliy if you watch this video...... humidification and dehumidification......well done sir
The best explanation so far on RUclips excellent teaching methods fantastic analogy. Please can you make video How to troubleshoot AHU using real world example by utilising Psychrometric chart?
Now I've understood dehumidification and humidification..thank you sir.

thank you so much, sir. Everyone with doubts in Psychrometry should see this.
Thanks for your support
Sir u please make a video on heating and humidification and dehumidification and that too with the help of an example... because it makes us vry easy to understand
so heplful all four videos in this chapter
Really Appreciative....very useful and understand in simple manner thanks a lot for your efforts.
excellent explanation...in simple words
Thank sir, the teaching is nice. I finally understand the cooling with humidification.
Lectures like u r born very very rare
Kudoos sir ji thanku

Excellent awesome
This video is nice sir. It helps a lot to understand psychometry. Please rectify the snoring sound around you. It irritates the watchers. Thank you!
lol
SIR, your explanation is the best sir. kudos to you
manish chinna thank you very much..watch all the videos regarding psychrometry if u need it..and any problem comment, I will try to help you out.
Really helpful sir thank you so much sir 👍
Very nice and good explanation sir but when explaining about dew temperature you haven't mentioned that we are decreasing temp but we are keeping the pressure constant. Thank you so much for the video👍
Great lecture sir .
Thank you for making psychometrics easy for me
u dig it deeper.very good expl. wid example very nice.
sir pl explain dehumidification & humidification which we run at same place like factory to reduce electrical consuption
Very nice lecture.
When 3rd part is coming sir?
Very nice explanation .😁
Saath hi rain ka concept bhi samajh a gya sir
Good videos I must say!! Really helpful in understanding the concepts
Wow..That's y thr is water coming out from all AC's fitted in our home..I always wonder frm where water comes ....
Excellent indeed!
Great. 👍
Thanks for your help sir , tommorow is my oral and test both includes this topic
Very interesting sir
thank you for this. and it's so fun because someone is sleeping and snoring hAhaha

Thanks a lot sir
Ur way of understanding is very nice
What if the temp of coil is above DPT?
your explanation is superb sir thanks for making the video its a very much helpful video sir . can you make the video for summer air conditioning system
+MOHD ZUBAIR ohhk I will try to do it.thank you very much for your valuable feedback
Good explanation sir ... my question is why does water evaporate in evaporative cooler ( what is the reference of this property in psychrometric chart ? ) ... Cause water boiling point in 1 atm pressure is 100 C . Is that mean we decrease pressure inside evaporative cooling chamber ?? Thanks ...
Nice one sir
Superb sir make more videos
how is the water from the jet evaporates as boiling point of water
is 100 c na???
Thanks for the video, I've gained a lot of info from this video :D

Very nicely explained sir. Dehumidification is imperative in Spray dryers. Can u please post links for videos in connection with dryers sir.
Very Good Explanation,Thank You !!!
If we design coil temp not below the dew point temp of particular air state condensation never gonna happen. Is it correct
Some one s sleeping in ur room
Hahaha
veeramani krishnan focus on lesson not snoring of someone sleeping in the room
YEAH , I will remember the knowledge in my life
Thank you sir can you please tell heating with humidification and dehumidification where it use in practical application?

Super ji
Go on.....
nice explaination....
Sir how can we control humadity in AC room .. bacause at certain temperature humadity will 100 and after it will condensate ..
The lecturing is very nice.👍👍👍
But yet someone is sleeping heavily 🤣
All concepts got cleared
Sir, In cooling with humidification diagram u did not show change in temp,I think it should be inclined to low temp instead of being straight. thank u
No no listen properly in case of perfect humidification I might have shown straight line....but in case of cooling with dehumidification the line will be inclined heading towards lower temp. As you have said
THANK YOU SO MUCH!!
Great explanation of the psychometric process, but I am hearing someone snoring in their sleep in the background noise.
Hahaha. Thank you. You r from which country
for the cooling by humidification, must you consider latent heat of water?

Nice job Sir
Please upload the video of operation research.
Really helpful, thanks sir
where are u from?? which state>?
What about in coastal area some time high Dbt and low humudity ......
good explanation sir..
sir am preparing fr rrb alp job. my trade subject is R&AC. so pls make more videos on R&AC subject
Thanks sir make more videos on hvac
Is there any lecture on heating with humidification?
I have not yet uploaded video on that topic dear.. you may find it on any other RUclips channel or you can also refer to any book. Thank you.
Sir can u plz tell how we can show cooling with humidification process on psychrometric chart
real nice explanation
great explanation
braj bhushan thank you very much for your valuable comment.
Do I hear snoring in the background?
Latent heat effect on wet bulb temperature and dry bulb temperature
too good sir
Sir,What is temperature of water in the cooler after passing dry air...will be high or low if high then how?
See it is simple..water will take up the heat from the air...thereby it's temp. Will rise little bit and temp of air will decrease
