HVAC 011 Evaporator Coil introduction

[@fabiodarocha2842]

You are passing important information to us. You should have by now about a million followers. People just don’t know how valuable all these information are to us.People should realize that it costs big money to learn all this. Congratulations!! You are amazing.

Love that you cover the basics diligently. Thank you.

[@resurgensix]

Yes these up-close examples w/color coding helps us visualize more effectively. 👍

[@austinl9846]

keep them coming. love these

[@love2hvac]

Glad it was helpful!

And as iam in HVAC testing r n d ...do make some videos on testing lab standards

[@Mk_vloggs]

Would love to gain more knowledge from u

I have a friend that worked in a lab he donated tons school an official wind tunnel for testing and proving equipment operation. Unfortunately the school dint see value and scraped it out. I was heart broken.

Hello, TY for the vids, Im just learning & really appreciate them!! Does the superheated liquid enter the evap from the bottom?? Or top?? My bokk states from the bottom but my instructor said it come in frkm the top. Now I am confused!!

[@love2hvac]

Well there is not superheated liquid. Your at video 11, keep watching the videos in order and you will fully understand the concepts by the end. To answer your question, Subcooled liquid enters the metering device, leaving the metering device is a saturated mixture of approximately 75% liquid 25%vapor. That saturated mixture enters the evaporator coil at the bottoms. After all the liquid changes state to a vapor the vapor then continues to absorb heat and superheats above saturation. The superheated vapor leaves the evaporator at the top of the evaporator and traveles towards the compressor/vapor pump.

[@notnecessary7730]

@@love2hvac thank you responding. Yes I should of said superheated liquid/ vapor mixture. I was confused because the book stated enters the bottom and exits the top but my instructor insisted it enters the top. He seemed ticked off I was asking especially when I questioned gravity and liquid being heavier than vapor & running down and not vaporizing thereby entering the suction line unless their was a collector lower than the vapor exit port. But again he just said ITS THE TOP and seemed annoyed I was asking!!! so, I just let it go. THANK YOU for responding, I always want to learn as much as I can

[@love2hvac]

@@notnecessary7730 yes it definitely enters at the bottom and leaves at the top in most cases. For clarification it's a saturated liquid/vapor mixture. It can't become superheated until all the liquid is completely gone.

@@love2hvac Thank you very much!!

[@dario6749]

I always wonder why there are not fins on coils made out of cooper.

[@love2hvac]

You can special order them via customer coil manufactures.

[@Mk_vloggs]

Hi sir can u explain the effect of different CFM on ahu unit...like 650cfm , 900 and 1250. Along with inlet air RH effects

[@love2hvac]

I will be doing a video on that soon.
