that is the best lesson for people to understand how the hvac works. great job eddie! thank fors sharing your experience.
nice job Eddie. I learn something today, I been in the office to long. now I doing my own thing and I need to refresh my brain.
This information video not only helped me completely understand how subcooling and superheat works. But the analogies gave me a better understanding of how A/C works. ESP when the refrigerants turns from gas to liquid. Thanks Eddie!!!
You made this very easy for me to understand, there is a whole community of people out there that think this way sir. you are not alone. thank you very much for your analogies dont stop making them
That was AWESOME! You would make a great TEACHER.
i watch this about 3 times,each time i got something more from it,it made me get it a little better each time,and i do get your -35,and when i am able im going to use this and then take a closer look to see how close it is,ive ck some of my older notes that i kept and it seems to be on the money almost every time or within 1,thanks for a different look at things,cant wait for more!
Eddie, your sense of doing things right are not boring. Keep up with the quality you try to offer. Good job.
Great job Eddie. I applaud you for exposing some of the people who are given the job of teaching. I believe that they don't really understand the subject well enough to explain how a system works. They throw around some definitions and skim over things that need explanation. Next thing you know, they are on to the next topic and repeat their spill if you ask them a question. Thanks for finally explaining super heat as it applies to a working ac system. Great job.
Thanks for the video I'm trying to better understand super heat and sub cooling and that helped put it into a better perspective
I like it Eddie I really do. Just payed this for some folk's as they know nothing about thing's so when a technition comes at them with these terms like dry bulb - wet bulb & super heat & sub cooling al factors in getting a handle on how their system is performing with the numbers being read by the device person!! Excellent :)
Hello Eddie, Your analogy works very well for me. Thanks for using this unique technique to explain the same subject and make it easy to understand.
I hope that later you will go back and remake this video on this fantastic drawing and talk about, latent & sensible heat, the receiver, the accumulator, the heat exchange affect shown on the drawing. You missed marrying the technical aspects of this drawing with your hands on experience. Your videos are still some of the best.
No problem man, I know you are busy, especially this time of year. Thanks for taking the time to make these videos. I am looking forward to more!!
wonderful explanation! very easy to understand, i am a new student and you level of explanation is just top of the line! Thank you
Great Video! I'm going to tech school right now and we are studying refrigeration. This video makes it very easy and clear to understand. Great Work! I use your videos all the time for reference and learning. Keem em comin!
Thanks Eddie, for making ac simple, keep teaching, I understand better thanks to you.
Clear as day thanks answered all questions in 4 minutes.
Thanks Eddie,
When I first started I never could understand high pressure/low pressure subcooling/superheat gas/liquid boiling point and so on, thanks for another great vid brother.
Kevin
Great video, man. Really appreciate you putting this on here to help all of us out here trying to learn this trade.
The best explanationninhave ever had omg, lmao. Thank you dude
May not learned about superheat and subcooling, but I know how I feel when I get home. :D
great freaking video dude, if u didn't understand that then i don't know what to tell you. pretty straight forward. i need more videos !
definitly in my top 10! Awesome way to put it!!
Not bad man, I guess if the evaporator was home and the compressor was work, then the condenser could be the bar / happy hour spot. lol..... Either way, you did a job well enough on this tutorial to get more positive responders than the negative ones. Keep up the good work.
I got the "Eddie talk"...Thank you!
Lmao this was funny as hell. Just wierd. “Spittin fluid” 😂😂
Thanks Eddie,
I knew the concept but using the thermometer is what I find the best info ever. Now I can do everything I need to do short of replacing a low refrigerant. In the case of a heat pump, such as what I have, I can measure the subcooling in the summer at a certain ambient temp outside and the superheat during the winter at a given temperature set point on the air leaving the vents and never leave the inside of the house. Base line data is your friend. You can buy coil cleaning solution in a spray can at Lowes. Clean at least once a year.
Great video I like that 35 degree minus the return air thanks
really enjoyed the lesson eddie..keep it up have great day
Perfect. I am trying to get a better handle on this and I like the way you think. People I talk with seem to dance around the question. Leads me to believe they don't really know what they are doing either. I have a much better understanding of what the meanings are. Now to just put it into practice. Thanks
Great video my friend , I am learning a lot from your videos.
Great Video Eddie! Thanks
Thanks Eddie! Lots of good info. You should add a link to your list if that is possible. I haven't even figured out how to get a video on here yet! Ha ha.
thanks Eddie keep them coming!
Awesome way to explain! I totally get it now. ty!
Great instructional video Eddie.
Pressure tempture chart 134a
If you know HVAC like the back of your girlfriends head then this is not the video for you. This is a way that was explained to me and it worked for ME.. It may not be for everyone but if it helps somebody who looks at things a little differently from you then my job is done.
I went to your channel to watch your videos and I couldn't find any. Your way of explaining it will have everyone understanding the refrigerant cycle, Maybe you should do some videos ;)
Great video. Thank you. I understand it a little bit better. Appreciate it.
You are welcome my friend and This is what I like to hear, someone that understands Eddie talk.. lol
This helped a great deal. Thank you.
I like the video thanks Ed good job explaining it . One thing though when I get home or when I relax at any point in the day me and my crew call that Kickin OFF on DEFROST .
Awesome!!! Bro. Thank you!!! :-) it made sense to me!!! Make more!
Very well explained Eddie, thank you
Eddie, just wanted to say thanks for the explanation! I recently switched careers from an Electrician to an HVAC tech and I am about to start training for my EPA certification. This explanation really helped me understand refrigeration cycles in relation to their components.
just wondering why you switching trades
+All In One Home Repairs Didn't really switch trades, found it beneficial to be versatile as far as abilities are concerned. I'll say one thing HVAC work comes easy if you already understand the electrical side of it.
80 % of HVAC problems are Electrical.
Thanks for sharing this video with others, I appreciate it
Thus is the explanation that I've been looking for
I enjoyed your video thanks.
Hey Eddie !!!
Great Analogy Brother !!!
I think Everyone has there own Style of Learning , i'm Visual like You , and it took me a Minute also to get my Head around this , that is the Reason I like RUclips where I can Actually see it Demonstrated !!!
Appreciate you taking the Time to do this Video !!!
Xanax I love it !!! LOL ... Vapoorize !!!
Great Video Eddie !!!
We all had trouble with Superheat and Subcooling and pressures I know I also had a hard time. I never went to Hvac school I learned by buying books asking questions and RUclips videos that you nice people post now it's been 7 years certified and know more then some kids just getting out of school. It's scary when people from big ac companies come to my job site and break there heads and finally you have to help them trouble shoot unit.
I believe in you Eddie. Thanks for the video.
Love your vid yo!!
good job eddie i am looking on the best way to explain how things work in system on my videos i picked up a fue good tips , you know in the real work things are not always idea ..sometime you rob from peter to pay paul is a good analigy .i am going to watch all your stuff eddie your a smart dude i have alot of respect for you brother rock on knowing how thing work and explaining sometimes things right is a different story
Very useful. Many thanks.
Very helpful thanks man
Great video, ty
taking heat out of the house in your analogy is like coming home and becoming a psychiatrist for your significant other , and allowing her to blow steam at you, HAHAHA. I cant stop laughing. thanks for this analogy man.
good explanation. thanks!
Sorry for the delay it has been rather crazy around here lately..
With this video you get to see how my brain works towards most things lol..
I'm gald that you were able to pick up on something from this video!!
To tell you the truth I felt like I went over the deep end on this one but I will let the viewers decide on that one..
Maybe we have other Eddie thinkers on here.. lol
Thanks for watching Ray!
very nice scheme Eddie
Thanks I appreciate that!!
thank you very helpfull
Thank You!!
Good explanation, thanks
Thanks I understand it now!
awsome job
Great example!
Have nice day and merry Christmas Eddy, from Québec city.
Bonne journée et joyeux Noël Eddy, de la ville de Québec.
Thanks Eddie
I thought you explained the low side well! I enjoyed the video.But the high side not even close. You have to understand saturated refrigerant to teach this properly. I would enjoy visiting
good video I like it
Thank you Sir.
Thanks man helped me out alot! But on superheat and subcooling say if you have a 30 degree sh i know its undercharged but wouldnt that mean itll actually do better because your picking up 30 degree difference of hot air going across that evap? And same question just reversed for subcooling
this is more understanding video,i like it...
HEY EDDIE AM A 30 YEAR VETERAN A.S.E CERT. MASTER AUTOMOBILE TECHNICIAN.GOOD VIDEO AND THE WAY YOU EXPLAIN HVAC SYSTEM IS CORRECT. THESE GUYS THAT DONT UNDERSTAND OR GIVE YOU NEGATIVE FEEDBACK. WELL JUST LET ME SAY THIS JUST LOOK AT THEM THEY DONT LOOK SMART AT ALL. AS A MATTER OF FACT THEY ARE LOST IN SPACE WITH NO HOPES OF RETURNING BACK TO EARTH.MAYBE THEYLL FIND A JOB CARREER IN SPACE AS HAIR DRESSERS.
thank you
Cool man Thanks!!!
Be sure to check out my other videos so that I can BORE you some more..
Have a great day!!
Thanks for the comment!!
When you run into a problem give me a call;)
I seen your video and watched most of it but wasn't for me, but I was able to interpreter on how you were explaining it and wat u meant, you do have funny way of explaining it. I mean I'm not an expert but I'm general technician and understand many languages in many forms with the high ability for interpreting and cross referencing. this is the same information on super heat but coming out being explained through your perceiving filter, ur way of viewing it, n understanding to be simple. 1/2
Some hvac teachers is they too good & too fast too smart... Hey good video thank you
Condensing factor for for a 10 seer fan cooled condensor is ambient air plus 30 to get proper head pressure you said 14 or something i don't know where you get those numbers from but you will have freezing indoor coil around 30 degrees unless you get that head pressure up to bring up the suction pressure. Pressures/temperatures go together low head pressure=low suction pressure.
Thanks
Could you explain the last part were you add the 20 degrees.
Thank you for your time. Honestly analogy of house work not that good but the rest was helpful, you might consider just leave the second part.
very nice
kinda long to get to the point, but good point at the end..
Thanks for watching Fritz !!
If only we could give these air conditioners some Xanax when they start to fall apart.. lol
2/2 to be simple on it some someone else can catch it.
and just as you explained it, that if some else that thinks and understands differently gets in than you did your job. I want to cross reference this from both sides that people in the bigger picture on bigger scale in the world have different views and so on, many come across each other and disagreeing or will catch eye to eye (agree). and that is the lottery of people walking about each other. I view people as particles as in physics.
what they dont learn from me hopefully they will from you.
Thanks for watching!!
ive been having the same issue with this topic, a lot of instructors dont explain it properly and make it overly complicated. when in reality super heat is just the difference in temp between the boiling (saturation) point and whatever temp reading youre getting off the gas/vapor....and subcooling is the temp difference between the boiling point and liquid.
So does this mean that if my AC just keeps blowing colder and colder and colder air - colder than the setting, it is not sufficiently heating up the already cold air? And if that is the problem, how do I fix it? Is the refrigerate low or needing to be replaced? Great video, but still not sure how to fix the problem of the the house being "super cooled" lol ..
super heat and system super heat are basically the same, you may gain a little heat in the line sets but nothing to be concerned about.
Super heat is the amount of heat that the refrigerant is able to absorb from the hot air flowing through the indoor coil which is basically a really big heat sink. that's why they call it Super Heat we are adding heat.
Sub Cool is just the opposite, we are measuring how much heat that is removed from the refrigerant by the out door coil..
Remove heat = subcool
make since thanx
HELLO, how will you know the compressor that is good or bad?. OK thanks
So it's backward the heat side makes the cooling and the cooling side gets ride of the heat
How do I get the correct target for superheating. The unit does not have the chart. Ur time is greatly appreciated.
Here's how I figure superheat target...."Indoor wet bulb temperature x 3 - 80 - outdoor dry bulb / 2"....example: Indoor wet bulb = 67.....out door dry bulb = 90....."67 x 3 - 80 - 90 = 32....32 / 2 = 15.5....superheat target is 15.5....It always works for me!
Grate video, but I'm still confused with super heat and system super heat.
I'm still trying to figure all of this RUclips stuff out myself.. lol
Oops Didn't think u would hAve seen the comment. U sure know what u r talking about, just being a clown love to watch ur videos thanks for answering my question Lol
Being on youtube I have to have pretty think skin so I don't take any comments to heart.. I actually got a laugh out of yours lol
More focused on the analogies than the actual refrigerant process. Way more drawn out than it had to be.
Don't worry Haters hate
I never understood anything you said buddy. I’m confused now eddy.
