Isn’t this the same thing as a peltier/ TEC? I thought those were hugely inefficient.
Something sounds very wrong with this. The heat pump designs do not create greenhouse gasses except when using power from a dirty source or if the refrigerant is leaking.
But the jargon in this is strong so maybe I am missing something.
You are correct in that the only way VCC cooling creates more green house gas emissions than the ECC cooling is if the VCC leaks freon. I'm very intrigued by this new tech, and I'll have to do...
You are correct in that the only way VCC cooling creates more green house gas emissions than the ECC cooling is if the VCC leaks freon. I'm very intrigued by this new tech, and I'll have to do more research, but this article seems very click bait venture capitalist style fluff. It claims that ECC is more efficient, but doesn't give numbers or data. This article is a bunch of fluff really. I hope we can get better data on this cooling method.
I believe the peltier effect works by using two different materials (semiconductors?) and applying current, which results in the two materials ending up with a temperature difference. This effect...
I believe the peltier effect works by using two different materials (semiconductors?) and applying current, which results in the two materials ending up with a temperature difference. This effect is using a single material, so that part is different, but the linked article was heavy on the marketing, low on the science so who knows how well it actually works or will work eventually. And yes, the peltier effect is quite inefficient in my experience, though admittedly fun to play with for cooling a PC.
There is still belief that the Peltier effect (and related Thermoelectric effect) can be made to work better if we can find some material that conducts electricity really well but conducts heat...

The wiki page for the electrocaloric effect specifically states it should not be confused with the peltier effect. The source study is a review of the current state of things and while there have been improvements, it seems the hope is mainly in the promising looking models.
Refrigerant leakage shouldn't be underestimated in my opinion as there are established rules of thumb for leakage rates. Especially in small residential installations leakages don't even have to be reported a lot of times. So an alternative without these problems would be great.

It probably looks like a magnetocaloric refrigerator
except using an electric field instead of a magnetic field. It probably is cycling the electric field on a material, which heats or cools it, lets it come in contact with either the hot or cold side, come to equilibrium, then cycle again and switch sides. It might have a single crystal which has changing connections or an array of crystals on a wheel.
The changing electric field plays the same role that compression or expansion of a gas plays in an ordinary refrigerator, but in the ordinary refrigerator you can compress or expand the gas and then send it through a pipe to a radiator which you can’t do with an electrocaloric solid.
