Abstract

The present invention relates to a heat pump (1) having a heating mode and a cooling mode, and a corresponding method of operation, the heat pump (1) comprising a refrigerant circle (200) and a hydraulic circle (100), the refrigerant circle (200) including a refrigerant configured to circulate through the refrigerant circle (200), a compressor (12), an internal heat exchanger (10) and a directional valve (14), in particular a 4/2 way valve, wherein the internal heat exchanger (10) is configured to exchange heat between the refrigerant and a hydraulic liquid configured to circulate through the hydraulic circle (100), and the directional valve (14) is configured to invert a flow direction of the refrigerant in the refrigerant circle (200) to change between the heating mode and the cooling mode, further comprising a second directional valve (50) configured to invert the flow direction of the refrigerant or the hydraulic liquid over the internal heat exchanger (10), such that the refrigerant and the hydraulic liquid flow in counter current through the internal heat exchanger (10) in the heating mode and the cooling mode.
