How does a Refrigerator work?

Have you ever wondered how the refrigerators in your home work? Refrigerators, which have become an integral part of every household, work based on some simple and interesting scientific principles. Beginning with a basic refrigerator model, this video will elaborate on the operation of modern refrigerators, along with the secrets behind their high energy efficiency.

I couldn’t sleep because I NEEDED to know how a refrigerator works. Now that I have been enlightened with this knowledge I can finally go to sleep without worrying about anything

If you're wondering WHY the pressure drops when it goes through throttling device, it is due to the Bernoulli effect.
A key property of this effect is that as velocity increases, pressure actually decreases (contrary to common expectation).
So, as the liquid flows from a large diameter into a smaller one, the flow velocity increases and thus the pressure decreases.

"This is the most basic refrigerator possible ever"

lmao something about the way he says that cracks me up

We own a 20 year old refrigerator with freezer and a 40 year old freezer. Both of which are either on or off and are very reliable. I like it when I purchase a product and it stands the test of time.

It's really amazing how much impact refrigeration had on our progress as a society.

"The throttling device is an obstruction to the flow, so a huge pressure drop occurs..." You should elaborate on this because 1. It is the essence of why it works. 2. The way you say it is counter intuitive. Why would liquid lose pressure when pushed through a smaller space?!
The point here is that the same amount of liquid has to pass through a smaller diameter in the same time so the speed at which the liquid passes a given point is higher. According to Bernouilli's principle a fluid/gas that moves faster has lower pressure and vice versa. This is also what makes a plane fly.

Very insightful. I'm an electrician in the Navy and we occasionally work on refrigerators very similar to the one depicted. Thank you for the info.

This seems fully comprehensible only by physicists or engineers, but I did get a little from it. I just got a new fridge, myself, and I was wondering what had become of all of those coils that used to be on back or underneath. Now I know the answer at least to that. I also know why my new fridge is almost totally quiet.

The logical next step would be to make a video about compressors. It would be very awesome if you could also explain what a reciprocating compressor is. Thank you very much for your effort in educating us. I will start supporting you on patreon once i have a job :D

Iam indian but I don't know proper english but u r animation is so clear

This narrator sounds like the how it’s made narrator

Wow so much engineering ingenuity in one device, yet we just take it for granted

Hi from HVAC-R Engineer, State Polytechnic of Bandung, Indonesia
Thanks for making this video, good explanation & animation

I can't believe I didn't think about this first.

this knowledge is more important in my life than pythagoras theorem

Shit, man, I felt a substantial leap of quality here. well done guys!

I have found this channel very useful because it provide all information very clearly with no music and introduction. Thank you! That’s all what we want as well as keep it up
