Abstract

Es wird eine Wärmepumpe mit einem Kältemittelkreis beschrieben, der einen Verdichter (1), einen Erdkollektor (4) und einen Wärmetauscher (3) zwischen dem Kältemittel und einem Wärmeträger sowie eine Umschalteinrichtung (2) zwischen einem Heiz- und einem Kühlbetrieb des Kältemittelkreises umfasst, der in Abhängigkeit vom Heiz- oder Kühlbetrieb für die Beaufschlagung des Erdkollektors (4) oder des Wärmetauschers (3) zwischen Kältemittel und Wärmeträger mit dem zu verdampfenden Kältemittel gesonderte Beaufschlagungsleitungen (8, 9) mit je einem Expansionsventil (6, 7) aufweist. Um vorteilhafte Umschaltbedingungen zwischen Heiz- und Kühlbetrieb zu schaffen, wird vorgeschlagen, dass für das Expansionsventil (6) in der Beaufschlagungsleitung (8) des Wärmetauschers (3) zwischen Kältemittel und Wärmeträger eine Umgehungsleitung (18) mit einer Drosselwirkung vorgesehen ist.

A heat pump with a refrigerant circuit is described which comprises a compressor (1), a ground collector (4) and a heat exchanger (3) between the refrigerant and a heat carrier and a switching device (2) between a heating and a cooling operation of the refrigerant circuit. having depending on the heating or cooling operation for the application of the ground collector (4) or the heat exchanger (3) between the refrigerant and the heat carrier with the refrigerant to be evaporated separate admission lines (8, 9), each with an expansion valve (6, 7). In order to provide advantageous switching conditions between heating and cooling operation, it is proposed that for the expansion valve (6) in the admission line (8) of the heat exchanger (3) between the refrigerant and the heat transfer medium, a bypass line (18) is provided with a throttle effect.
