Definitions

  • the invention relates to a heating system according to the preamble of patent claim 1 and a method for operating a heating system according to the preamble of patent claim 7.
  • a heating system of the type mentioned above is known from the patent document CH 556 513 A
  • a heat consumer namely the space heater with reference number 17, is arranged in particular on the first partial heating circuit.
  • a heat consumer namely the boiler with reference number 19, is also arranged on the second partial heating circuit.
  • this solution also provides a bypass, namely the mixing line with reference number 21.
  • Another heating system of this type is known from the patent document EP 2 530 391 A1
  • This consists of an overall heating circuit carrying a heating circuit medium and a first and a second partial heating circuit, each connected to the overall heating circuit and also carrying the heating circuit medium.
  • a valve device is provided for determining a heating circuit medium volume flow through the partial heating circuits.
  • the valve device has a first connection connected to the second partial heating circuit, a second connection, and a third connection connected to the overall heating circuit.
  • a heating circuit medium is carried in an overall heating circuit.
  • the heating circuit medium is carried in a first and a second partial heating circuit connected to the overall heating circuit.
  • a valve device is used to determine a heating circuit medium flow rate through the partial heating circuits.
  • the heating circuit medium flow rate is supplied to the second partial heating circuit via a first connection of the valve device and/or via a second connection of the valve device. Furthermore, the heating circuit medium flow rate is supplied to the valve device via a connection connected to the overall heating circuit.
  • the second connection of the valve device is connected to a mixer line, which essentially connects the flow line of the overall heating circuit with its return line.
  • Other heating systems of this type are known from the EP 2 306 096 A1 or EP 3 594 575 A1 known.
  • the invention is based on the object of improving a heating system and a method for operating a heating system of the type mentioned above.
  • a particularly well- and easily controllable heating system with (at least) two partial heating circuits is to be created.
  • a buffer storage tank is provided in the second partial heating circuit.
  • the method according to the invention provides that the heating circuit medium flow is directed through a buffer storage tank at the bypass when required.
  • the solution according to the invention is characterized by, and in contrast to the aforementioned state
  • the technology is characterized by the fact that, thanks to the inventive arrangement of the valve device and the inventive control of the heating circuit medium volume flow, the second partial heating circuit can be controlled completely independently of the first partial heating circuit.
  • the inventive solution it is even possible to essentially control the temperature of the second partial heating circuit solely via its pump, without affecting the first partial heating circuit.
  • the overall heating circuit 1 has a flow branch 1.0.1 and a return branch 1.0.2.
  • the flow branch 1.0.1 and the return branch 1.0.2 are connected to one another via a heat exchanger 9 on the one hand and via the first and second partial heating circuits 1.1, 1.2 on the other.
  • the said heat exchanger 9 which ultimately preferably has four connections (not separately shown) and is designed as a plate heat exchanger, is in turn designed, for example, as a condenser of a heat pump.
  • several such heat consumers are generally provided.
  • the solution according to the invention also has another pump, but not - as in the solution according to Figure 3 - second partial heating circuit pump 10' on the first partial heating circuit 1.1, but a total heating circuit pump 10 arranged on the return line 1.0.2 of the total heating circuit 1. Furthermore, a bypass 7 is provided on the second partial heating circuit 1.2.
  • a heating circuit medium is guided in one or the overall heating circuit 1 in the solution according to the invention.
  • the heating circuit medium is guided in a first and a second partial heating circuit 1.1, 1.2 connected to the overall heating circuit 1.
  • a valve device 2 determines a heating circuit medium volume flow through the partial heating circuits 1.1, 1.2.
  • the heating circuit medium volume flow is supplied to the second partial heating circuit 1.2 via a first connection 2.1 of the valve device 2 and/or via a second connection 2.2 of the valve device 2.
  • the heating circuit medium volume flow is supplied to the valve device 2 via a connection 2.3 connected to the overall heating circuit 1.
  • connection 2.2 is connected to a feed 1.1.1 to the first partial heating circuit 1.1.
  • the heating circuit medium volume flow is supplied to the first partial heating circuit 1.1 via the second connection 2.2 of the valve device 2.
  • valve device 2 is arranged on the flow branch 1.0.1 of the overall heating circuit 1.
  • valve device 2 guides the heating circuit medium, if required, either completely through the first partial heating circuit 1.1 or completely through the second partial heating circuit 1.2. Furthermore, in contrast to the solution according to Figure 3 and less fundamentally than described above - preferably provided that the valve device 2 is used to set a distribution of the heating circuit medium flowing in via the connection 2.3 to the connections 2.1, 2.2.
  • a line branch 3 with three line connections is particularly preferably provided on the return branch 1.0.2 of the overall heating circuit 1, wherein the first line connection 3.1 is hydraulically connected to the first partial heating circuit 1.1, the second line connection 3.2 is hydraulically connected to the second partial heating circuit 1.2 and the third line connection 3.3 is hydraulically connected to the return branch 1.0.2 of the overall heating circuit 1.
  • a first, preferably valve-free, branch 6.1 be provided on the second partial heating circuit 1.2 in the flow direction of the heating circuit medium, on the one hand, upstream of the partial heating circuit pump 4 and upstream of the heat consumer 5, and on the other hand, a second, preferably valve-free, branch 6.2 be provided downstream of the partial heating circuit pump 4 and downstream of the heat consumer 5.
  • a bypass 7 is provided on the first partial heating circuit 1.1.
  • the two branches 6.1, 6.2 are hydraulically connected to one another via the bypass 7.
  • both the first partial heating circuit 1.1 and the second partial heating circuit 1.2 seen in the flow direction of the heating circuit medium, each have a connection interface 5.1, 5.2, 11.1, 11.2 for the partial coupling and decoupling of the two partial heating circuits 1.1, 1.2 upstream and downstream of the heat consumer 5, 11, it finally advantageously results that, in addition to the valve device 2 and the buffer storage tank 8, both the overall heating circuit pump 10 and the partial heating circuit pump 4 can be arranged at a central location in a building.
