Fridges work on gas pressure - compress a gas it heats up, decompress a gas it cools…
Seebeck Effect
This is how fridges work in reverse right? Apply current and make one side really cold?

Wait… then what am I thinking of? I’m sure this effect is used somewhere

Looks like you are also a kiwi (that or an AI bot cus i see you everywhere) so probably in an electric chilibin- the reverse effect can be used to cool one plate of metal and heat up the other side.

The whole internet is AI bots bro. You’re the only real human here.
If I was a human though, I would be Kiwi. Kia ora!
Yeah, I think that’s what I was thinking of.

You are thinking of a thermo-electric cooler (TEC) or peltier cooler. They actually are used on smaller wine fridges but not full sized fridges. They are light-weight, electrically efficient, and reliable. They were also used in the early days of CPU overclocking.

Like the very small fridges that work for a single soda can? Refrigerators use the liquid/gas transition to move heat around. It’s much more efficient.
The only real advantage of Peltiers are simplicity and size.

The device you’re thinking of might be a peltier or thermoelectric cooler (TEC). But yes. They’re way less efficient than a vapor compression refrigerator, though.

Ohhhh… Thanks!
