*Great and Easy to instal **Fastly.Cool** Low noisy*
By far the best video, starting from the basic principles, not over complicating and moving at a slow enough pace allowed for this to register in my head. Thank you so much!
I finally get it! Thanks so much for explaining so well. It's so easy to understand now.
I’ve watched many such videos but the penny finally dropped when I watched this one. Thank you. I love you-tube xxx
Excellent. Thanks very much Mike.
The best explaniation I have ever seen!
Incredible explanation. I'm surprised I didn't find this earlier - just what I needed. many thanks!
a video that explains its it in lamens terms then expands upon that as they go. genius really
Why are all your videos SO intuitive. Love your stuff.
Thank you both very much -- awesome videos. Putting the diagrams to the concepts will help me remember these on my arch registration exams!
As an electrical engineering student doing some mechanical based projects, this is very helpful!! Thank you!
This is SOOO GOOD, exponentially better than anything else I've seen. Amazing, this is how great teaching is done. Beautiful!
OMG this's excactly what i'm looking for. Thanks a lot!
Great demonstration
Its so great when things like this are actually explained properly in DETAIL stage by stage with all the nuts and bolts so to speak. So many useless so called teachers will ramble off jargon that people have no understanding of it in practical terms. They may pass some exam 'understanding' the theory as in being able to jus regurjitate what was "taught" to them but having no REAL understanding in practical terms of what that means! They then may become teachers and pass on the crap understanding and explanation they have to others and so the problem is exaccerbated! Core understanding is key so great video anyway!
Thank You very much for the illustration. This is a very easy way of explaining the physics of refrigeration. I love the illustration, I wouldn't have it anyway explained than that! Thank You! :)
Fantastic explanation. No other video or book could have explained this better.
the best explanation I've seen on the net. thanks
this video is great! thank you!
Amazing! Very comprehensive
I used this video in an 8th grade science class and it worked well. The theme of the lesson was conservation of energy. This short video nicely fleshed out this complex idea.
Great stuff... Very easy to follow and to understand for a guy like myself that didn't realize how it works.
Good explanation. Maybe a little technical for a lot of people, but I like it.
Very well done. Thank you.
Beautifully explained
Very helpfull, thanx a million
very well explain and now I understand better what they are. Well Done. Keep it up.
Thank you so much!
It is really amazing explanation through an animation. Now I can clearly understand that how does an AV work. Thanks!
I will watch more to make my own. Thanks.
brilliant! thank you
Thank you so much for this. God continue to bless you Sir.
Intuitive explanation for a complex topic. Nice work!
Excellent video explains clearly. Good job hope to see more of this kind of video.
Thank you
Great video! Thank you
Thanks, finally got it (after watching at least five other videos).
After 5 years studying mechanical engineering, only now it makes sence and it will never be forgotten.....it was very helpful thank u professorermann
Thank you so much for this excellent explanation.
Just great! awesome and simple explanation!!
Not everyone understands this relationship between pressure and boiling point.
I remember, during one of my interviews, I was asked to explain the refrigeration cycle. When I started talking about BP at the condenser side, the interviewer told me, "What is the connection of boiling point when it is already gas in the first place (after compressor)?". I told him to let me finish my explanation first.. lol.. but when I got into the evaporator side, he just realized how stupid his question is. It's thanks to my instructor that I understood this process.
FYI for other people who are new to this:
High Boiling Point means Higher Vaporization and Condensation point. Meaning that gas will turn to liquid at a higher point and vice versa.
at the Evaporator side:
Low Pressure, Low Temp and Low Boiling Point.
Since we dont want to increase the temp so much just to evaporate the liquid refrigerant, we will now have to reduce the pressure.
I hope it helps. :)
YESS!! This did help! I do BAS controls as an EMS guy, controls specialist but I'm more of a programmer, I don't know the mechanics as well as I should but that's when I just ask the HVAC tech guys like yourself and they explain it to me lol
+j kelz. It all becomes a lot simpler to understand when you incorporate suction regulators into the design concept. By relegating the pressure, you control the the boiling point of the refrigerant, you get a fixed temperature (vital in direct expansion air conditioning to prevent ice on the evaporator). It also has the advantage of preventing the evaporator from flooding and returning liquid to the suction side of the compressors, where it will cause serious damage. A correctly designed evaporator will allow all the liquid to evaporate before the end of the coil. The amount by which the gas heats above its boiling point is controlled by the expansion valves to about 3 degrees. That rise in temperature is the superheat figure.
Traditionally all these controls were spring loaded mechanical devices, but many of them have been taken over by electronics.
It is better to always think mechanical. That way, you will see in your minds eye exactly what is going on and how the programming needs to support it. Done the other way around will lead to endless confusion and the possibility of serious and costly mistakes.
I hope that this helps.
I have designed systems for theaters, cinemas and film studios. The change in load as audience attend and leave the building is a major consideration, making these systems quite unique. 2000 people produce a lot of heat (approximately 250 Kw when enjoying the performance) LOL
What a clear video thanx
Excellent, thanks for uploading it.
Most interesting video ever made on RAC.... all doubts are clear now... Thank You!!!
Thank you :')
Love this dude's voice.
Many thanks.
Cool! Thanks!
thank you very much, well done, helps a lot
Most informative video ever!!
Thank you... awesome video.
Awesome Explanation
I've always wanted to know how my ac works. Thank you!
Thanks very much. Like most things, simplicity made more complicated with computerisation. :)
Thought I'd add a bit more detail. Pay no attention to anyone objecting to this video. Everything he says is correct. To explain it more precisely requires some knowledge of Thermodynamics and the Carnot heat engine.
I would augment this fine video with Wiki ("Heat pump and refrigeration"). Pay special attention to the 5-pt Thermodynamic diagram of Figure-2 as it relates to Figure-1. The accompanying text explains everything for the cycle.
Nice work Mike !!
Great Work!
This is VERY VERY well done, great job. One of the best videos I've seen. You're a gifted teacher. Keep up the great work!
Fantastic video! Loved it!
Very interesting! Thanks for sharing
Awesome explanation
most easiest to understanding for me! thanks a lot sir
Very well explained
Great video!
Awesome video! Thank you for sharing.
Thanks for the video! I've always wondered how air conditioning works. I understand the physics of fluid getting hot when compressed, and cold when expanded. And I understand how the fluid is compressed to make it hot on the hot side. But I couldn't imagine how a reverse compressor works to keep the pressures separate on each side. So it's simply a valve that lets just a little bit of the fluid pass, that keeps the high pressure side pressurized... Thanks!
Superb. Thank you.
lotsa thanx for this video...i just started HVAC PHASE ONE at VATTEROTT....this dumbs it down enough for me.
Amazing video!
This is very interesting!
awesome ty trying to learn this is not easy great video
Fantastic.
Thanks :)
wow thank you so much,,, awesome video !
Etc and this helps a lot thanks :D
excellent video
Excellent. Thanks. I finally get it..........I think!
Great!
Awesome
WOW! you made this video so understandable, a caveman could do it! Keep up the Great work!
Best video!
Thank you for this video series. Now I understand air conditioning and heat pumps very well!! I particularly appreciate the very detailed systematic build-up to a more complex system :-) Thanks, great video
sorry to be so offtopic but does someone know a trick to get back into an Instagram account?
I stupidly lost my login password. I would appreciate any assistance you can give me
@Marlon David i really appreciate your reply. I got to the site through google and Im waiting for the hacking stuff now.
Seems to take quite some time so I will reply here later when my account password hopefully is recovered.
@Marlon David It worked and I actually got access to my account again. Im so happy:D
Thanks so much you saved my ass!
@Colton Hugh happy to help xD
Blady brillaint, I feel smarter and the best explanation out there.
The best explanation of air conditioner.
Agreed. This is great.
Very informative
excellent information
NICE VIDEO
It increases heat transfer. The heat from the coolant can more easily be transferred to fresh 80 degree air than the air that has already been heated to 90.
Yes, you're right. In the illustration, it shows the return air @ 70F which is correct. But it also shows the evap temp @ 50F when it should be 40F. The outside condenser temp is normally 125F. So he does'nt explain superheat and subcooling temps.
very good
very nice video
Very easy to understand! Can you do videos on how plumbing and structure in architecture works as well? thank you!
Awesome dude. Just what i was looking for
Yes. Very interesting. So basically I got that hydrofluorochlorocarbon goes from liquid to gas. This is an endothermic reaction. So heat is absorbed. Then it is forced to being a liquid again outside the home and the process starts all over.
Great video! Everyone should watch this video. Here at Einstein Air we understand this better than most!
Cool
Good and simple explanation. I go back to this video every time AC topic comes up.
Warning to new viewers: Please do not waste your time commenting on Justin Snyder's post. Do not get carried away. Even a boiling water in a vacuum container is not hot. Try it.
+Jeff SC You don't have water in a "vacuum". Wise up!
whahahattt??? hahahaha. freak.
Thanks again. From the diagrams, it seems like pressure is created by "jamming" the fluid downstream into the expansion valve, which only releases just so much. In other words, it gets "backlogged". But pressure creates heat - and this is happening well after the fluid moves out of the condensing unit. So heat is created after the compressor, further down the line where the condensing fan can't get rid of it. No?
One more thing to help you understand if you actually want to justin. Have you ever been outside swimming on a low humidity day? If you pay attention you will feel much colder than a muggy high humidity day because the water is evaporating much faster. As it does it is taking the heat away from your body to make the phase change.
elemento1991 Water evaporates FASTER on a hot day than it does in muggy weather. That's why you feel wet in humid climates and not in really dry climates. Humidity means it isn't evaporating as quickly. My, you are one uneducated person. Second, we were talking about boiling not being cold. Evaporation is the result of heat. An ice cube doesn't evaporate, because it's cold/frozen. Take it out and it evaporates. That's what melting is, EVAPORATION from hotter air. Wise up!
Thank you for the explanation. I am trying to understand the basics or air conditioning. It has been a challenge to find something explain it simply.
i wish there were more graphics explaining key points on this. some of us are visual (not auditory) learners.
Great vid. I've watched all three parts, but still not sure at what exact points the refrigerant actually changes states - liquid, gas, liquid, gas, and what exactly makes them change states.
wow, finally, i understood the whole thing...thank god. i was thinking in the physical aspect of the liquid so my temps were backwards of my mind, but then i understood that the heat require to evaporate the liquid was no longer there cause i spent it all evaporating the liquig so the resul was COLD. YEAH ME
