Abstract

A liquefier for a heat pump includes a liquefier space, a compressor motor and a motor fixture for holding the stationary motor part, wherein the motor further has a motor shaft and a compressor wheel connected to the motor shaft. The motor fixture is formed so that the stationary motor part is held so that it is in contact with liquefied working fluid when liquefied working fluid is filled in the liquefier space. Furthermore, the compressor wheel extends into a region of the heat pump in which a channel for gaseous working fluid to be compressed passes.
