- In this video, I describe how the evaporator will absorb heat, some heat will be latent and some sensible, and how to tell which heat is it absorbing more of.

I have been in the game a little bit, and always want to stay on top of my science and not get lazy! You refreshed me and I'm hooked on your videos!
Ha ha! Thank you for saying that! I know it's hard when you're in the field and don't deal with this stuff every day. I'm glad to hear these videos help some of you guys out there stay on top of the game. thank you!!!
THANK YOU COMMING FOR FUTURE GUIDANCE MY HVAC TEACHER ISNT NEARLY THIS GOOD MOSTLY TEACHING MYSELF
Thank you!!! I like teaching. I am glad I can help you some. check out my webpage. I will have an online class starting soon. www.airconacademy-courses.com/
Fascinating that you can write backwards and with both hands!
Thank you! One day I was in high school, I was bored and all of a sudden I realized I could do that lol who knew that I could learn this kind of stuff sitting in the back of English class lol I hope you like the video. And to keep learning.
Indeed!! Thank you! I was trying to figure that out. "How is Julio doing that? Does he have two special cameras and one of them is backwards or something?" 😂 LOL
Great explanation.
Thank you! And thank you for watching!
Excellent video
thank you so much and thank you for watching!!!!
Thanks champ! I always come here for further guidance on these concepts
Thank you!!! I hope I can help more ion the future!!!
Very nice explained sensible and latent heats thank you sir I already subscribed to your channel
Karim Mecherfi thank you!!!
Great video thanks
Thank you for your comments and thank you for watching!
Thank you I am understanding it,,, Im beginner tech..
Hello, It was so nice video so much good and clear information didn't know that. Can you make a video of how a refrigerant boiling point changes with pressure and how the refrigerant can cool a freezer to -6 degrees Celsius for example if it only came in the liquid line at 12 degrees Celsius. I would so much appreciate that. Thanks and much appreciated!!!
Thank you for your comment! And that is an interesting request! I had not thought about doing a video on cascade systems! Excellent idea thank you for watching and thank you very much!
great stuff thank you for the video!
I'm so glad that you enjoyed the videos and I hope they are helping you at work! Again, thank you and good luck out there. Keep learning!
Thanks a lot
Thank you for watching and thank you for your comment!
Thanks for the lecture Sir Godbless
You are welcome but Thank you!!!! I need all the blessing HE will give me!!!
Thanks big times.
I am glad I can help!!!!
Waw , that's awesome!!
Thank you! I'm very glad you liked the video. I hope it helped! And thank you for watching!

It just clicked with me on the sensible and latent heat. You have explained it in a simple effective way Keep it coming. Thank you.
@@samyz1660 thank you so much! I'm glad it helped it quick! And thank you so much for watching!
keep the good job up man and i hope that you upload clip about duckless mini split unit and can we charge mini split unit with capillary tube using super-heat or at least can we measure it
How do you ascertain the saturated temp therefore latent heat in a room that the evaporator has to deal with.
I am not quite sure what you're asking. But I hope this helps. We would like the evaporator to be approximately at 40°F. Because of that the suction pressure when you look it up in the PT chart should be very close to 40° we are absorbing sensible and latent heat in the evaporator. Heat is heat whether it is sensible or latent heat. This heat will be absorbed by the refrigerant and evaporator and that is going to make the refrigerant boil at a specific rate. The evaporator is designed to absorb a specific amount of heat with a specific amount of airflow, and the combination of the two will give us the correct amount of gas, leaving the evaporator. The evaporator is going to absorb this heat from the air and the more humidity you have the more dehumidification it is going to do, less humidity the more temperature difference you are going to see. I hope this helps and I hope this answers your question. If it does not, please feel free to send me another message. And thank you for watching!
I have a question. what happens if you introduce hot food suddenly into the evaporator (freezer). how does the load in the compressor vary? i would be grateful if you could do the math and make a video out of it.
Because of the warm food, the suction pressure would increase putting a load on the compressor, making it work harder. They refrigerant is going to boil faster increasing the low side pressure and the compressor will have to bring that back down to the desired suction pressure so you can have the correct temperature evaporator. I will see if I can do a video on that. Thank you for the suggestion!

How it will be the compressor situation in case the ac system supported by capillary tube compare to txv ?
Actually I like the way you present your topic it's clear , academic and simplify.
@@AlmarbadiT I believe I have a video about the five different types of metering devices, and I believe I explain the difference between a TXB and capillary tube. I'm not sure if I go into how it affects the compressor. But when you have a TXV we do not need to worry about flooding the compressor or not having enough refrigerant in the evaporator. Because of that we do not have to worry about getting liquid back to the compressor and destroying the compressor. With a capillary tube if the load increases in the evaporator we may starve of the evaporator therefore increasing the superheat. It is the cool super heated refrigerant vapor that cools the compressor. If the suction gas has to much superheat it may not cool the compressor well enough. The capillary tube systems are not as efficient as the ones with TXV's. I hope this answers your question, thank you for sending your question in.

Thx a lot sir ... appreciate for your help.
😊
Thank you!!! and thank you for watching!!!!
I need both on ac and fridges
Yes! The evaporator on the AC and on the fridge are both going to absorb sensible and latent heat.
The difference is that in the refrigerator the evaporator is going to freeze and the defrost cycle will drain that water/condensate down and out! Thank you for watching!
Excellent explanation. Thanks
Thank you! I am glad you liked the video! And thank you for watching!
