Definitions
- the invention relates to a heating system according to the preamble 5 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 is known from the patent document 10 CH 556 513 A.
- a heat consumer namely the space heater with the reference number 17
- a heat consumer is also arranged on the second partial heating circuit, namely the boiler with the reference number 19 .
- a bypass is also provided in this solution, namely the mixing line with the reference number 21 .
- Another heating system of this type is known from 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, with a valve device for determining a heating circuit medium volume flow through the partial heating circuits being provided, with the valve device having a first , connected to the second partial heating circuit connection, a second connection and a third, connected to the overall heating circuit connection.
- a heating circuit medium is routed in an overall heating circuit.
- the heating circuit medium is routed in a first and a second partial heating circuit connected to the overall heating circuit.
- a heating circuit medium volume flow through the partial heating circuits is determined with a valve device. Furthermore, the volume flow of the heating circuit medium is fed to the second part of the heating circuit via a first connection of the valve device and/or guided via a second connection of the valve device. In addition, the volume flow of the heating circuit medium 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 basically connects the flow line of the overall heating circuit with its return line.
- the object of the invention is to improve a heating system and a method for operating a heating system of the type mentioned at the outset.
- a heating system with (at least) two partial heating circuits that can be controlled particularly well and easily is to be created.
- a buffer store is provided on the second partial heating circuit.
- the invention provides that the heating circuit medium volume flow is guided through a buffer storage tank on the bypass if required.
- the solution according to the invention is thus and in contrast to the aforementioned state the technology from the fact that the second part of the heating circuit thanks to the inventive arrangement of the valve device or the inventive management of the heating circuit medium flow rate is completely independent of the first part of the heating circuit can be regulated.
- the solution according to the invention it is even possible to control the temperature of the second partial heating circuit basically solely via its pump, without influencing the first partial heating circuit.
- FIG. 1 shows a first representation of the heating system according to the invention
- FIG. 2 shows a second representation of the heating system according to the invention, but which hydraulically corresponds to that according to FIG. 1;
- FIG. 3 shows the heating system (represented in simplified form) known from the prior art mentioned at the outset (EP 2 530 391 A1).
- the heating system shown in Figures 1 and 2 consists in a manner known per se of an overall heating circuit 1 carrying a heating circuit medium and a first and a second partial heating circuit 1.1, 1.2, each connected to the overall heating circuit 1 and also carrying the heating circuit medium, with a valve device 2 is provided for determining a heating circuit medium volume flow through the partial heating circuits 1.1, 1.2, the valve device 2 having a first connection 2.1 connected to the second partial heating circuit 1.2, a second connection 2.2 and a third connection 2.3 connected to the overall heating circuit 1 having.
- the overall heating circuit 1 has a flow line 1.0.1 and a return line 1.0.2. 15 Looking more closely, it is also preferably provided that the flow line 1.0.1 and the return line 1.0.2 are connected to one another on the one hand via a heat exchanger 9 and on the other hand via the first and second partial heating circuits 1.1, 1.2. Said heat exchanger 9, which ultimately preferably has four connections (not shown separately) and is designed as a plate heat exchanger, is in turn designed, for example, as a condenser of a heat pump.
- a number of such heat consumers are provided.
- a partial heating circuit pump 4 and at least one heat consumer 5, particularly preferably underfloor heating or a radiator are also provided here as a rule. 5
- 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. Furthermore, with a valve device 2, a volume flow of heating circuit medium 20 through the partial heating circuits 1.1, 1.2 is determined.
- the volume flow of the heating circuit medium is supplied to the second partial heating circuit 1.2 via a first connection 2.1 of the valve device 2 and/or passed via a second connection 2.2 of the valve device 2.
- the volume flow of the heating circuit medium is supplied to the valve device 2 via a connection 2.3 connected to the overall heating circuit 1.
- the second connection 2.2 is designed to be connected to a feed 1.1.1 to the first partial heating circuit 1.1.
- the volume flow of the heating circuit medium 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 line 20 1.0.1 of the overall heating circuit 1 .
- valve device 2 is used to route the heating circuit medium, if required, either completely via the first partial heating circuit 1.1 or completely via the second partial heating circuit 1.2.
- a distribution of the heating circuit medium flowing in via the connection 2.3 is set to the connections 2.1, 2.2.
- a branch line 3 with three line connections is particularly preferably provided on the return line 1.0.2 of the overall heating circuit 1, the first line connection
- the second partial heating circuit 1.2 seen in the flow direction of the heating circuit medium, on the one hand 10 before the partial heating circuit pump 4 and before the heat consumer 5, a first, preferably valve-free, branch 6.1 and on the other hand after the partial heating circuit pump 4 and after the heat consumer 5 a second, preferably valve-free, branch 6.2 provided. It is also - which is particularly clear from the representation 15 position according to Figure 2 - on the first partial heating circuit
- a buffer storage tank 8 is provided on the second partial heating circuit 1.2. Provision is particularly preferably made for the second partial heating circuit 1.2 to be provided with the buffer storage tank 8 which is hydraulically connected on the one hand to the first branch 6.1 and on the other hand to the second branch 6.2. This preferably has a volume of less than 30 liters, particularly preferably less than 20 liters. - Expressed in terms of the method, it is provided that the heating circuit medium volume flow is routed, if required, via a bypass 7 provided on the second partial heating circuit 1.2 and there is passed through a buffer memory 8. It is particularly preferred that a portion of the volume flow of the heating circuit medium that is routed through the buffer tank 8 is controlled by the valve device 2 and by a speed of a partial heating circuit pump 4 of the second partial heating circuit 5 1.2 .
- both the first partial heating circuit 1.1 and the second partial heating circuit 1.2 seen in the direction of flow of the heating circuit medium are in front of and after the heat consumer 5, 11 has a connection interface 5.1, 5.2, 11.1, 11.2 for partial coupling and decoupling of the two partial heating circuits 1.1, 1.2 the partial heating circuit pump 4 can be arranged at a central location in a building.
