Abstract

In order to improve the exchange of energy between cooling and heating processes a vaned impeller is proposed, the vanes 2 of which consist of a hollow profile open in the direction of rotation, which in the area close to the hub has an axial inlet expansion 5 on the admission side and is provided on the outside end with a radial outlet aperture 6 together with a baffle element 7 curved in the direction towards the outflow side. In this way a spiral, radial flow behaviour is produced by means of which a high volume or mass flow circulation rate is achieved at low speed.
