Refrigeration - Pressure Enthalpy Chart

[@alechiggins6515]

Thank you so much. If it wasn't for all the Indian instructors on RUclips I would have never obtained my engineering degree.

[@PercivalFakeman]

Thank you for a fine description. You kept it simple. That is the best place to start.This one of the best learning tools I have seen on this subject.

[@andrewsfiindje9194]

Thanks helping me. I clearly understand this now. God bless your hard word.

[@mustangsandwich]

Good stuff! Needing to review this now in my work and it's been years since I last messed with it. Great review.

[@kikkirow]

This is so confusing and this class is so difficult. Thanks for making good tutorials.

[@pauljuneau8974]

Again! GOOD WORK! Looking forward to viewing more!

Excellent Video
Keep up the good work

[@ykhairnar]

Good explanation on the PH chart in simplified manner.

[@kyugreywolf6801]

Awesome video, thanks. Better than any other video I've seen on this curve ,^^

Nice explanation of the P-h diagram

[@darkopodbevsekster]

clear and logic explanation lots of thanks Sir

[@vishaldebnath2881]

thanks sir... for such a simple explanation... thank you.

[@lizzettei.888]

Doctor, nice presentation. May I ask what video software are you using and what digital pad are you utilizing to write on your back screen

[@RPaulSingh]

Thank you! I use Camtasia software and Intuos tablet to prepare the tutorial.

Thank you!!

[@madhavdixit9992]

But why do we draw it ... What is the purpose of drawing it?

[@RPaulSingh]

Good question! The purpose of drawing a PH chart is to understand thermodynamic properties of a refrigerant, and the process of how refrigerant changes its phase from liquid to gas and then back to liquid. The role of pressure becomes evident as you traverse a refrigeration process later on this diagram. Once you have drawn the PH diagram yourself on a piece of paper, your understanding of the vapor compression refrigeration is enhanced. These are some reasons why many find this approach useful. I hope that it is helpful to you.
