A POSITIVE DISPLACEMENT DEVICE

摘要

A heat pump having a rotatable casing and impeller. The pump includes a liquid heat exchanger and an air heat exchanger both connected to the casing so as to form a rotatable unit therewith. A magnetically active rotor is magnetically coupled to the inpeller to provide a drive force for the pump. Rotation of the impeller causes the casing and heat exchanger to also rotate under the influence of reaction forces.
