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
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 ...
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
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.
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
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👍
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?
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
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
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.
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
One of the best teachers of the psychrometric processes hands down! Fundamentally sound.
Thanks 👍

Thanks bro. That was very explicit
If we design coil temp not below the dew point temp of particular air state condensation never gonna happen. Is it correct
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 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👍
thank you very much sir .. keep doing
Nice job Sir
Sir but lt crosses the limit of dpt n dpt was 15degree celsius how than 9degree will be on the curve
All concepts got cleared
Heating and humidification pe vedio bnaiye sir vedio is too good
sir pl explain dehumidification & humidification which we run at same place like factory to reduce electrical consuption

I meant Horizontal
What if the temp of coil is above DPT?
Good Effort sir. Thanks a lot. It's really helpful.

braj bhushan thank you very much for your valuable comment.
Sir please make a video on concept of draft tube in depthly...
Sir can u plz tell how we can show cooling with humidification process on psychrometric chart
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
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
The lecturing is very nice.👍👍👍
But yet someone is sleeping heavily 🤣

Rohit Chowdhury thank u 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
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.
please explain problems on psychometric
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..?
Dheeraj Prabhu latent heat of condensation taken by the coolant in coil and it's temperature increases.
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.
