Still I can't really think about any mass produced consumer item that includes a heat pump and is not either part of building/car cooling/heeting or a refrigerator itself.
Like mobile base stations of course have AC units and some amateur astronomers use peltier cooled sensors, but I would hardly call these mass produced consumer items.
