yakhchal
A type of icehouse, built mainly in Persia (present-day Iran), that functions as an evaporative cooler, having a domed shape above ground and a subterranean storage space.
Furthermore, constructions such as the Yakhchal and Abanbar, which were built exclusively to stock water, had to have direct access to water courses.
Where it comes from
Borrowed from Classical Persian یَخْچَال (yaxčāl, literally “ice pit”).
