1858?

As an ice making machine, rather than as a refrigerator:

The one I know

https://en.wikipedia.org/wiki/Einstein_refrigerator

is 1926. By a couple of guys called Einstein ans Szilard you may have
heard of.

AB Arctic produced a commercial refrigerator, based on an improvement to
the original cycle, in 1923. Electrolux AB bought AB Arctic in 1925 and,
as your article mentions, also later bought out the main Einstein patents.
