A heat pump (1) of the sorption type comprising a coolant circulation, having a mixture circulation (2) filled with a liquid mixture of substances, a condenser (3) giving off heat to a consumer circulation (6), a restriction (4) and a heat (9) absorbing evaporator (5), whilst the mixture circulation comprises a generator (10) heated by a heat source (12), an absorber (11) connected through a mixture inlet duct (18) and a mixture outlet duct (17) with the generator (10) and also giving off heat to the consumer circulation (6), a restriction (13) included in the mixture outlet duct (17) and a mixture pump (14) included in the mixture inlet duct (18). The mixture is a mixture of high viscosity operating at low pressures and the mixture pump (14) is one of the type having a rotatably driven rotor (20) and a stator (21), at least one of which has at least one spirally or helically extending groove (24) in a surface facing the other. |
