Thank you very much. Your classes are good. Expecting videos on basic of thermodynamics especially the concept of entropy which is very much confusing.
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?
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.
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👍
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
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
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.
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 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
Sir in cooling and dehumidification. How can we say that relative humidity increases?? even the capacity of holding moisture decreases because of cooling but moisture content also decreasing because of dehumidification . So we can't say whether decreases or increases.
rajendra karedla see basically this cooling with dehumidification process takes place in room air-conditioner suppose.... There humidity off course decreases alongwith temp. that's why you get the comfort.. And that's why you will see that always some water is dripping from the outside of air-conditioner... That water is extracted from the moist air only.
Digvijay Sainik see try to understand your question is really nice...but I have to understand your question more deeply ,because there are lot of factors responsible for this..better if you google it. Thanks..any problem always keep commenting.I shall try to help you out as much as possible
Digvijay Sainik there are basically 2 ways to change the state of the body: 1st by changing temp(critical being at boiling and freezing point) and 2nd by changing pressure (critical being at vapour pressure of the corresponding body), now if the pressure of the body is low enough it converts into gas from liquid without changing temp. Since Pv is small the droplets could be in superheated state at normal temperature.
I have one doubt. What happens to latent heat of condensation during cooling and dehumidification process. Doesn't it increase the temperature of air as in heating and dehumidification process..?
sir . i have one question that whether the fan is used for suction or throwing cooled air to the room. because the fan is present at the front. pls explain.
+Manu Siddharth Bhatt try to understand fan is used for various reasons.but here it is used for drwaing the outside air, inside the cooler..so that when the air passes through the cooler it cools down because of water sprays
Sir,relative humidity is Mv/Ms is temperature is decreasing Ms decreses ,but Mv increasing so how can you tell that relative humidity incresing with out considering effect of Mv
sai chand no no...dear try to understand.....you listen to my this video and other videos also.... I hv always said that mv is constant...and why it is constant that also I hv explained.
One of the best teachers of the psychrometric processes hands down! Fundamentally sound.
Thanks 👍

Thank sir, the teaching is nice. I finally understand the cooling with humidification.
excellent explanation...in simple words
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?

YEAH , I will remember the knowledge in my life
Thanks a lot for uploading such a nice one
sir pl explain dehumidification & humidification which we run at same place like factory to reduce electrical consuption
Thank you sir can you please tell heating with humidification and dehumidification where it use in practical application?
Thanks for the video, I've gained a lot of info from this video :D
thank you for this. and it's so fun because someone is sleeping and snoring hAhaha
ruclips.net/video/SLmv3lgWvFI/видео.html
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 ...
Please upload the video of operation research.
Some one s sleeping in ur room
Hahaha
veeramani krishnan focus on lesson not snoring of someone sleeping in the room
Thank you so much sir . Brilliant explanation .
Thanks sir make more videos on hvac
Thanks bro. That was very explicit
Sir can you show the humidification and cooling in psychrometric chart??
Sir plz make video on heating with humidification and heating with humidification
Thanks Sir
you've clarified some good pts
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
Excellent 👌 I'm HVAC design Engineer
Very nice lecture.
What if the temp of coil is above DPT?
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?

I meant Horizontal
sir can u explain cooling affect in this tropic..and explain heating with humidification and heating with dehumidification
thank you very much sir .. keep doing
Which temp,you are talking about either dry or wet bulb
Superb sir make more videos
sir plz upload problems related to psychromerty it will be great help
Sir please upload al lectures of power plant engineering subject
Very good, keep it up.
how is the water from the jet evaporates as boiling point of water
is 100 c na???
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
Excellent indeed!
The lecturing is very nice.👍👍👍
But yet someone is sleeping heavily 🤣
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
Very interesting sir
Great. 👍
If we design coil temp not below the dew point temp of particular air state condensation never gonna happen. Is it correct
Sir how can we control humadity in AC room .. bacause at certain temperature humadity will 100 and after it will condensate ..
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
Nice one sir
All concepts got cleared
What about in coastal area some time high Dbt and low humudity ......
nice explaination....
for the cooling by humidification, must you consider latent heat of water?
@@Nandhakumar-nj6gu ruclips.net/video/SLmv3lgWvFI/видео.html
ruclips.net/video/SLmv3lgWvFI/видео.html
Sir but lt crosses the limit of dpt n dpt was 15degree celsius how than 9degree will be on the curve
Sir can u plz tell how we can show cooling with humidification process on psychrometric chart
Really helpful, thanks sir
Super ji
Go on.....
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,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
Nice job Sir

Dheeraj Prabhu latent heat of condensation taken by the coolant in coil and it's temperature increases.
please explain problems on psychometric
Latent heat effect on wet bulb temperature and dry bulb temperature
great explanation
braj bhushan thank you very much for your valuable comment.
real nice explanation

Sir, but then why we are using such a assembly.?
Do I hear snoring in the background?
Sir,relative humidity is Mv/Ms is temperature is decreasing Ms decreses ,but Mv increasing so how can you tell that relative humidity incresing with out considering effect of Mv
sai chand no no...dear try to understand.....you listen to my this video and other videos also.... I hv always said that mv is constant...and why it is constant that also I hv explained.
sai chand ruclips.net/video/NmGw-n-LZZ8/видео.html
Sir at 10:15 you said moisture content is increasing
Water vapour is going in to air means moisture content is increasing
