Bro I’m still confused. So you are telling me I take a refrigerant (some liquid that can be condensed quickly?) boil it, have room temperature air cool it back down into a liquid (where it started) put it into an expander where there is less pressure so it looses more heat, then use this liquid to cool down the inside of the fridge and then rinse and repeat? I feel like the expander is what is messing me up, how does it cool the liquid below room temperature?
so we're using compressor to increase pressure hence increasing temperature, But when the refrigerant comes from cooling stuff it is already in a hot state so why do we need compressor?
I'm late to the party, but without the compressor, the refrigerant can only get as hot as the inside if the fridge. 2-4 degrees C. The compressor makes the refrigerant hotter than room temperature, which allows the heat to move from the coils to the air of the kitchen.
For me the key point to understand this is knowing that change in pressure will change the temperature, the rest you can guess with a little bit of thinking, now I know why the spray can seems to get colder when allow air to get out, that's because of the decrease in pressure
There remains no liquid after the expansion valve. Introduction of heat does NOT cause vaporization, dropping the pressure via the “expansion valve” drops the pressure causes phase change resulting in cooling.
such a great explanation, happy to discover your chanel and that sucks you are not popluar but good luck in the future :)

Love u sir

I thought it was to keep the liquid moving constantly but also the same can be done with a turbine pump so I had the same question

This needs more attention, saved my life
how did it save your life? 😭
Great video, thank you very much , note to self(nts) watched all of it 3:06
Great explanation, thank you!
i played it on 0.75 speed as it was too fast for me, great upload
Without the compressor.. which gas use for refrigerator. .. using heater ss
I'm just here for the puns 2023 😆
The fridge explanation is great !
Obligatory this explained more sense than 1 hour of my physics lecturer from supposedly good university :)
My entire sem in 3mins lol
thanks a lot
Live u sir
