There is a fail in the Exploration of the Expansion valve.(13:10) it dosn't operate like this. If the evaporator is cold enough, the sensing refrigerant in the sensing Part retracts and closes the valve, becourse the refrigerant in the evaporator cant compleatly evaporate and so it makes sure that no liquid can go from the Output of the evaporator to the compressor. But its Position is between condensor and the evaporator. Its Sensor is connected to the Output of the evaporator. Think about the placement of the capillary Tube, its the Same as the Expansion valve. Also it closes when its Sensor gets to cold and opens when it gets warmer. (Sorry for some misspelled words, im german)😉

[@ksuwareh78]

Thank you so much, I have learned something interesting

[@headbanger1428]

Your simple-to-follow teaching videos contribute greatly to many lives around the world. Thank you. I wish KZbin (AKA Alphabet Corp.) knew that as well. C’est la vie.

[@willeveryday]

Brilliant video, it explains the process very well. Please, my spicy chorizo, investigate cascading cryogenic systems. As the temperature for each level decreases, it uses a more appropriate refrigerant for the temperature and pressures that will be required.

[@HighClassPythonS]

Hey how are you can you please help me..i have a portable ac it does work and cools but the compressor keeps turnin off, do knw what can be causing this, it cools for one min and then stops can it be a sensor or is it somethin i can fix??

[@heyderaliyev8976]

again you have proved with this video once again that *YOU ARE ONE OF THE BEST EXPLAINERS AND CONTENT CREATORS ON KZbin* probably one of the TOP TEN (y)

[@sabahjason1]

That was the best A/C how it works explaining i ever seen on youtube .🙏

[@Wonderworldrun]

Thank you, this is the best explanation I’ve found online

[@JjMn1000]

Some corrections for stuff in the video: Air compressors usually use reciprocating compressors which have pistons but these types of compressors which are a second type of rotary vane compressor have a different design. It is not a screw compressor and I have taken one apart before. You usually find screw compressors on large water chillers. The liquid dryer is before the metering device. R290 is propane aka a hydrocarbon. Hydrocarbon refrigerants do not have any ozone depletion potential aka ODP. HFCs like r410a(r32 and r125) have no ODP but they do have GWP aka global warming potential. Hcfc refrigerants like r22 are being phase out and have both ODP and GWP. Cfc refrigerants like r12 are VERY VERY BAD and are illegal. I agree scroll compressors are becoming more common but you will still see reciprocating compressors and rotary vane compressors. All motors that have VFD capability or multi speed capability can drive motors/compressors at variable speeds. Newer chillers usually have scroll compressors.

[@petersamios5409]

It's s scroll compressor.

[@stefano.a]

Beautiful video, thanks. It would be fantastic to see also how to build a little working model of an air conditioner using cheap (and non toxic) components. It would be the only one existing on KZbin

[@nemerissa]

I remember during my thermodynamics course back when i was an undergrad student, the most hard part fpr the teacher was to explain the refrigeration cycle!! Youn nailed it man 🔥 very well explained 🤙🏻

[@kcg795]

I did convert my portable A/C to a dual hose and that seemed to help a lot. I eventually upgraded to a mini-split system. The portables are just too loud and I hated that mine used my window. My 12,000 btu can get my room ice cold and not even be phased while it seemed like my 10,000 btu portable had to work overtime to get my room down to a comfortable temperature. Portables and window A/C units are fine if you're renting. But if you own your home, you can't go wrong with a mini-split. Best thing I've ever done. Might install one in the living room next.

[@ksull72487]

Mini Split is going to be the best. Wall or Window Units second. If in the states you need to look at BTUs SACC (Seasonally Adjusted Cooling Capacity or DOE) for portables. Since most portables on the market are less efficient. As of 2017 most of your 10,000 BTU units are far less. Many people tend to miss this when sizing one. Which is why the gov. changed the BTU rating system for portables. They do work if sized correctly and dual hose units seem to be a bit better. I do have 10,500 BTU SACC unit. Zero Complaints for the space it cools. Renting. Although they start to get quite expensive in this range.

[@Hieu.minh97]

How did you convert it? I want to convert mine as well

[@RowanYouTube]

​@@Hieu.minh97 avoid condenser coil to suck air from inside room. Close it and attach one hose pipe. The keep other end of the hose pipe outside the room. In short.. Existing portable AC has only one hose thats hot air out hose. Make one more hose set up at the inlet side of the condenser coil

[@viniciusnoyoutube]

I had viewed a lot of videos about the AC and the only thing that I couldn't understand was the expansion valve. Finally with your explanation and very nice diagram I understand now. There are two valves, one is the compressor and the other is the expansion valve. The expansion valve is an "open valve!" Thanks for the video!

[@ateebtahir7226]

[@brahampalsingh7420]

Best explanation of AC working . Just outstanding . Must watch video

[@The.Destroyer.Of.The.Worlds]

Thank you this clarified so many things

[@zuhriyuhyi]

Best explanation. Finally I understand how it works.

[@sailingeden9866]

Best air conditioner video I've seen, and I have watched a lot of them.

[@phil955i]

With a couple of exceptions, a very good explanation

[@SuperBlisss]

this video is good for understanding the basic ac process because it is explained very simply and diagrammed very clearly...thank you!!

[@Amit-wo4to]

don't worry about youtube algorithm ...your algorithm of way of explaination is great...one day whole world will know u❤

[@naufian]

I have watched so many videos explaining about air conditioning, and this video is by far the best one and easiest to understand.

[@lackr0073]

Love your videos! Couple correction. 1. Your fans are not turbine fans they are centrifugal fans. 2. It is not a screw compressor it is a rotary compressor. 3. The device on the compressor you referred to as a muffler is a suction accumulator (prevents liquids from being sucked into the compressor) 4. R290 is one of the most environmentally friendly refrigerants, but it is flammable. 5. The temperature sensors are likely thermistors and not thermocouples. Great video thanks!

[@ashok_ign5623]

Great Explanation 🔥🔥🔥

[@PhG1961]

Well I must say that I'm very fond of teaching/learning videos on KZbin. Indeed, I liked the video, I always do ! I enjoyed it very much an it was an nice refresh on heatpumps. And of course I leave a comment to trigger the KZbin algorithm. You deserve it !

[@PhG1961]

What about some improvements like using an Arduino/ESP8266/RaspB. to remote control and/or monitor this AC with a web interface and/or smartphone/tablet ? Seems like a challenge to me. And while I'm suggesting... why not try to do temperature measurements with the famous DS18S20 ! I like that one very much !

[@rajandeepsingh4945]

love from India 🇮🇳.... very well explained bro... i love your videos and love you too💕💕😘😘😘

[@L3v3LLIP]

Appreciate the first explanation.

[@mohamedabdikarim3128]

Thank you for sharing this knowledge. Great work yet simple enough to understand for everyone.

[@JakeJoris]

You could try converting this A/C to a more efficient one by adding a 2nd tube which will take the air from outside.

[@1234fishnet]

I was thinking the same...

[@JakeJoris]

@Tiago Ferreira I know, I have one.

[@gujarisantamanyugmai]

yes good idea!

Ur comments tell u hvnt got the principal of AC working and thermodynamics

[@iamjamesonbliss]

You explained how an AC unit works so well that everything finally clicked. Thank you. Your degree of knowledge and ability to describe the most technical aspects of a room air conditioner in the most simplest manner is exemplary. Bravo and thank you! You have a subscriber for life and, of course, will support as able.

Thanks the model you showed is very similar to my dumpster find. The controls are messed up and I hope to get it working with an Arduino. I wanted to know what the splash motor does, and you explained that very well. thanks for this video!

[@stephenyambor1422]

Thanks for taking the time to make this. Im a fan of the TXV, always thought about converting my fixed orifice so the compressor wouldn't constantly kick on and off. Anyway, great explanation of the components!

Learned a lot 👍

[@TonnyCassidy]

3:19 suction accumulator to stop liquid refrigerant returning to the compressor directly 3:26 liquid line filter/drier and capilarry tube metering device 5:03 thats the suction/return line, discharge line goes to the condenser to be subcooled and condensed into a liquid before going to the metering device to reduce the pressure and thats when it become cool high voltage capacitor ? nothing exceeds 1kv in there to be considered high voltage

[@erickiplimo]

Great expectation.

[@pizzablender]

Loved to see that water evaporator thing. I wondered how they do that, my guess was just dripping water over the condenser. But then the device would be useless as a dehumidifier (used without exhaust hose).

[@khaleedan]

Best explanation on youtube 👌

[@GodlessManitoban]

Very informative.

thank you very informative

[@HaiTHaMKoBeIssI]

thanks for the clear easy explanation.

[@nuzvidmusicacademy]

Thanks for educating us.

[@abhiram2916]

Now a days the compressor used is an inverter compressor. It work by converting the AC current into DC and a motor driver (inverter) convert the DC current into variable frequency AC, so that it can be used to drive the motor of compressor in variable speed. So instead of starting and stopping of the compressor like here, the compressor can operant at variable speed as load demands. Hope this was helpful...

[@zodiacfml]

nice post but from the new inverter airconditioners we have, I haven't seen one that continuously works at low power. I hope manufacturers have a feature or setting to restrict ac to lowest power or most efficient operation.

[@Not-C-418]

very good explaining from a good teacher thank you very much

[@gedis6090]

yes!

[@chelarestelar]

ive heard that there are models with two ducts: one to get outside air to cool the condenser and another to return that hot air to the outside, thus not creating the vacuum nor reusing the recently cooled air. also, this reminds me of the Technology Connections video about the subject

[@DanielAstro97]

Really clear explanation

[@kavehkarpoursafaei]

That's great man. i hope you continue your learning videos

[@oleeide9763]

Just some comments on refrigerants, r22 is banned quita a few years ago as it was really bad for the ozone layer, but r290 is just propane and its a environmentally friendly gas, with a really low GWP of only 3...

[@CJ-eo2xz]

That was very detailed and very well explained.

[@andrewgardiner3484]

i think that this video explains AC better than any others that I have watched. Thank you. Just one thing you may need to correct. The R290 doesn't damage the ozone but it is a greenhouse gas like methane and CO2.

[@NiHaoMike64]

Now mod it to attach a second duct for condenser cooling air.

[@tronixfix]

Just cut the crap apart and place the compressor and condenser together with fan, filter drier and capillary outside. Inside you just keep the control, evaporator coil and another fan as well as a driptray with drainage. Just have to connect it with longer tubes and charge the system properly.

[@salvatoremilitello8490]

i would love for you to make an arduino run that ac

[@narayanbandodker5482]

It might not be a good idea to hack into mains appliances. But if you want to, you can just replace the microcontroller with your own (Arduino, STM32 or whatever) and match the pins with the traces that go to the relays / sensors

[@salvatoremilitello8490]

@@narayanbandodker5482 how else would you run it on a Arduino if you didnt replace the board and use similar or those exact components simple reason for doing this is to make better pid controls with a wireless temp sensor to place in the middle of the room to insure that the room is temperature controlled instead of the air inside the case where the normal unit takes the temp and you could even make your own remote with the temp sensor inside lots of neat reasons that are extremly useful and innovative could lead to a new kickstarter for @Electronoobs a pcb set that is a universal drop in for units that work but the board is fried
