    • Heat exchanger arrangement (10, 10', 10", 10'") for a heat pump, comprising the following: - at least two heat exchangers (12, 14, 12', 14', 12", 14", 12'", 14'"), specifically a first heat exchanger (12, 12', 12", 12'") and a second heat exchanger (14, 14', 14", 14'"), wherein each of the first heat exchanger (12, 12', 12", 12'") and the second heat exchanger (14, 14', 14", 14'") is designed to allow a transfer of heat from a flowing operating medium, in particular from a gaseous operating medium of a heat pump, which is in a transcritical state, furthermore in particular from R744 in a transcritical state, to a heat-absorbing medium, wherein the first heat exchanger (12, 12', 12", 12'") and the second heat exchanger (14, 14', 14", 14'") are arranged one after the other in a flow direction of the operating medium and form a first heat transfer stage (18, 18', 18", 18'") and a second heat transfer stage (20, 20', 20", 20'"), each of which is designed to transfer heat to the heat-absorbing medium, and - at least one additional heat source (22, 22', 22", 22'"), which is arranged and designed to transfer heat to the heat-absorbing medium in parallel with the transfer of heat from the operating medium in the first heat transfer stage (18, 18', 18", 18'") and/or the second heat transfer stage (20, 20', 20", 20'").
