How does a cars Air Conditioning system work?

Well explained

Good

Just one mistake, if the temperature of the refrigerant is 0C going into the evaporator, then it must be warmer when leaving. Since Cabin air is what warms it, then the temperature of the refrigerant as it enters the compressor is probably around 20C (since it has be to less than ambient air temperature) and not 0C

Does the a/c clutch stay engaged all the time when the a/c is on and the car is working on park gear on idle (Altima 2010)? Thx

Very good explanation.

Best a/c demo.

@Garage tech, on the return circuit, is it not the hotter gas that comes back to the compressor? Not the cold gas as mentioned in the video. If it was cold gas, it was not required to be circulated back to the compressor. It should be hot enough to continue to be a gas but not hot enough for heat transfer with atmosphere which is why gas is compressed and sent to the condensor.

I understood everything up until you pushed hot liquid through a small hole to make cold gas?

Is there any way engine coolant and car AC system comes in contact with each other? Can a faulty AC repair can damage engine of a car?

Very straightforward explanation. I feel intelligent now 😅

Such great video, thanks for putting this together

Thanks for teh info buit I think you lost a bit of a track at the expansion valve mate.

the worst fucking goddamn long fucking ass video for smtn that takes 2 min to explain holy fuck wtf

Can you do a video on duel ZONE A/C

Perfectly explained. From the animations to explanations. Thank you very much! Cheers from USA

There is coolant, the condenser is new, the pipe is cold but inside my car it is not cooling, it is like fan only. What is the problem?

Question. My 2008 ranger is leaking red fluid, only when the ac is on. If I don't turn the ac on for a month no leak. I turn it on 3 minutes later red drops on the ground. The coolant is red. Could this be coolant leak if so from where. Any thoughts?

Wow, after many videos finally one that explains with the actual numbers... Thanks

Super easy to understand. Thank you a lotttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt

He said the whole thing upside down, and wrong... Just here the last minutes. You will understand he just dont know how the chilled gas came hot and boiled into the Compressor

How can i fix citi golf AC.

How does the compressor handles high rpm's? Does the valve lets more fluid flow, or does the cooling fan from the radiator helps it maintain a steady pressure inside the system? I know it has 2 modes, the normal and the max speed fan. Will it cool more if I maintain the engine at higher rpm's too?
Thanks!

Fantastic video. Top tier visuals and thoroughly but succinctly explained!

A little technical but I got it how it works great explanation 😃

The refrigerant vaporises as it absorbs heat in the evaporator thus then becoming a gas

Great video, but was it necessary to blast that music at the end?

wow amazing video ❤️

Great I’m a qualified mechanical engineer and auto electrical technician, and I never really knew about to much about a/c units until watching this video thanks, I’m more old scool..from the points ignition and carburettors ect ect..from the 70s..

Increasing the fan speed at the time AC is running, does it pull or increase the power the AC is taking from the engine

Thank you for the great video, it helped me a lot. 👍

Good explained

Thank you brother I want to know a little more detail about how cooling is circulated inside the car.

My dad says its from a fuel

What is the coldest temperature a car AC can achieve?

What's the type of gas used in the air con system? Is is it just fresh air?

Low volume? But thanks

What can cause compressor to be overheating

nice, but why is that fukkin loud music in the beginning and the end, literally blew my head off :(... at the same time your voice is super low

Great video and animation. I'm trying to troubleshoot an issue with my car's aircon. Had the compressor refurbished (twice) and and it works for a few months, then just won't engage (sometimes / intermittently) and airflow is not consistent (ie: seems to "cycle" between cold air and warm air "on occasion") and then doesn't work (at all) some days. Taking the car back, but I'd LOVE to to know anyone's thoughts on this issue. I live in a hot place, but still, that's that the aircon is supposed to do, right ! PLEASE help me understand this issue (if possible!) Thanks!

Nice 1. Told me exactly wha I wanted t know, and jus had t watch 1 time. Good on ya

At the expansion valve , it doesn't boil the liquid to make it a gas .
The physics is , if you suddenly compress a gas it will generate heat ..
(Compressor) If a gas suddenly expands , and hence drops in pressure it will cool down, enough to make ice.
If you open a valve at the end of a Compressor tank , as the compressed air leaves, and expands you will feel the metal outlet getting colder , and it may form ice , depending .
This is also only the cooling part of the A/c ....
The gas expands , drops in pressure , as you mentioned , and this is the cooling effect , its transfer of energy really ..
a full system would include that as the warm air is cooled over the evaporator, It cannot hold as much moisture .
Warm air holds more moisture than cold air , this will reduce the dew point and water will be separated from the air.
Resulting in cooler dryer air.
This water can be dumped out the bottom of the vehicle..
Don't freak out if you have water dripping from underneath your vehicle after a journey on a hot day , with the A/C on ..it's just this condensate being dribbled out

Good information 👍

the outtro almost blew my ears but cool video.

I would like to understand....is it by the connection of the compressor to the engine or by electricity from the battery ...how does it work ...

Awesome job man, thanks

Please add more details on how compressor run from engine and how air travels inside cabin,

I have never come across such a bad narrator for a video.

I learnt it was way back in 2014-15(engineering days)....But that time I was confused regarding this topic, finally I got the solution... The way u r explaining pressure & temp. at perticular point is just clear all the daught. Thanks
