You've made an invalid assumption. Every modern freezer I've seen
runs for the same time as older ones, and they cool at the same
rate. So clearly the compressor outputs the same cooling, but using
less electricity. All well and good, but I can feel the cold escaping
from the unit.

"cold escaping". There you go doubling down on your stupidity again.

There's no reason to think of it as heat. Have you never calculated
current flow imagining it flows from + to -?

You can't make cold unless you change the laws of physics. You don't
lose cold, you gain heat.

Did what I just said go right over your head? Most people think of electricity going from the +ve end of the battery to the -ve end. But we know that's the wrong way round. It doesn't matter though, the calculations still work.

In the same way we can think of a freezer losing cold, just as an oven or a house loses heat. Or in summer an air conditioned house loses cold. Technically the heat is entering the house through the walls, but if we consider the house losing 2C of cold, it's the same thing as it gaining 2C of heat.
