HEAT PUMP HEATING SYSTEM AND METHOD FOR OPERATING SUCH A HEAT PUMP HEATING SYSTEM

摘要

The invention relates to a heat pump heating system (1) having a working medium (2) which, in a closed working medium circuit, flows through a condenser that has at least one first and at least one second heat exchanger (4; 7) of which the respective primary sides are flowed through in sequence by the working medium (2), wherein the first heat exchanger (4) is arranged upstream of the second heat exchanger (7) with respect to the working medium (2), wherein the secondary side of the first heat exchanger (4) is flowed through by liquid (10) which is guided in the circuit by a first hydraulic switch (5), wherein the secondary side of the second heat exchanger (7) is flowed through by liquid (10) which is guided in the circuit by a second hydraulic switch (8), wherein the first and second heat exchangers are designed to transfer energy from the working medium (2) to the liquid (10) and thus heat the liquid (10) flowing through, wherein the liquid (10) in the first hydraulic switch (5) is at a higher temperature than the liquid (10) in the second hydraulic switch (8), having at least one first and at least one second heating water and/or hot water preparation device (11; 12), wherein the first (11) is designed for higher output temperatures than the second (12), having a hydraulic system (13) filled with liquid (10) that flows through the hydraulic system (13) in a heating circuit, wherein the hydraulic system (13) hydraulically connects the first and second heating water and/or hot water preparation devices (11; 12) and the first and second hydraulic switches (5; 8) to one another, wherein the hydraulic system (13) has a mixing valve (14) for changing and/or setting the hydraulic system in dependence on the current heating load of the first and/or second heating water and/or water preparation device (11; 12).
