Definitions
- the invention relates to a method for determining a current heat demand of a hot water circuit, in particular a hot water supply system of a building.
- the invention also relates to a heating device for Heating such a hot water circuit, which for Implementation of such a method is suitable.
- a hot water circuit can be operated using a heating device are heated, for example, by the fact that the Heating device by means of a first heat exchanger Coupling fluid circuit heated, which in turn over a second heat exchanger heats the hot water circuit. It is useful that the hot water circuit removable hot water always a predetermined Has hot water temperature. However, since usually the Hot water demand is not constant, but rather can be exposed to strong fluctuations Need to operate the heating device in such a way that if the hot water requirement varies, the hot water circuit always heated to about the same desired hot water temperature becomes. For this, a current heat requirement of the Warmwassernikes needed because this the thermal energy pretends to be from the heater to the hot water circuit must be initiated to the desired To reach hot water temperature.
- the current heat demand of the hot water circuit can for example based on the current volume flow in Hot water circuit can be determined.
- sensors are comparatively expensive. It therefore exists the need for an inexpensive solution.
- a first temperature in the Coupling fluid circuit at an inlet of the second Heat exchanger and a second temperature in the Coupling fluid circuit at an outlet of the second Heat exchanger used From these temperatures can by difference and / or averaging that of Coupling cooling circuit on the second heat exchanger emitted heat can be determined, which apart from Loss of efficiency in the hot water circuit introduced heat corresponds.
- the invention uses the realization that a pump that drives the Liquid in the coupling liquid circuit, is usually operated constantly. This results in always a constant relationship between the Temperature change of the coupling fluid circuit at the Flow through the second heat exchanger on the one hand and the current heat demand of the hot water circuit on the other hand.
- This connection can, for example be taken into account arithmetically and / or according to map to come from the measured temperatures to a value that corresponds to or with the current heat requirement correlated. This value can then be in the form of a corresponding signal a parameter for actuating the Form heating device so that it is possible to Heating device depending on the current heat demand to operate.
- the heat transfer numbers of the two used heat exchanger especially by calcification and / or pollution.
- the Change measured values of the temperature sensors used for example due to aging.
- a Burner of the heater during its runtime Change operating points This can cause it during the Lifespan of the heating device that the relationship between the temperature change mentioned above in the coupling fluid circuit the flow of the second Heat exchanger on the one hand and the heat requirement of the Warm water circuit, on the other hand, gradually changed. at is a further development of the present invention provided, by means of a third temperature, which is in the Hot water circuit at an outlet of the second heat exchanger sets to update the relationship mentioned.
- the permanent or periodically with even or uneven Time intervals can then be carried out a closed control loop that is quasi indirect affects the temperature control of the hot water circuit.
- the target / actual comparison of the hot water temperature is adapted the temperature control in the sense of a regulation.
- the heater can therefore show signs of aging be particularly elegantly balanced.
- the only figure 1 shows a circuit diagram Schematic representation of a heating device according to the invention.
- the first heat exchanger 4 is in one Coupling liquid circuit 5 is involved and is therefore of through a coupling liquid.
- the Coupling fluid circuit 5 is also a second one Heat exchanger 6 integrated, to which also a Hot water circuit 7, for example one not closer illustrated hot water supply system of a building, connected. Accordingly, the second one Heat exchanger 6 on the one hand from the coupling liquid of the coupling liquid circuit 5 and on the other hand from Water of the hot water circuit 7 can flow.
- the hot water circuit 7 for A building can be supplied with hot water Coupling fluid circuit 5 through a pitch circle Heating circuit 8 to be formed for heating this building.
- the coupling fluid circuit 5 as here a partial circuit of the heating circuit 8
- one Central building heating acts, connects a coupling branch 9 of the coupling liquid circuit 5 one of the first Heat exchanger 4 coming flow 10 of the heating circuit 8 with a return 11 leading to the first heat exchanger 4 Heating circuit 8.
- this coupling branch 9 is then second heat exchanger 6 arranged.
- Servomotor 13 To operate the changeover valve 12 is here Servomotor 13 provided.
- a first temperature sensor 15 which measures an instantaneous first temperature t 1 of the coupling liquid, is arranged in the coupling liquid circuit 5 between the first heat exchanger 4 and the second heat exchanger 6. Assuming that there is no or only negligible heat loss from the first heat exchanger 4 to the second heat exchanger 6, the first temperature t 1 measured by the first temperature sensor 15 corresponds to the temperature that the coupling liquid has at an inlet 16 of the second heat exchanger 6. Between the second heat exchanger 6 and the changeover valve 12, a second temperature sensor 17 is arranged in the coupling branch 9, which measures a second temperature t 2 of the coupling liquid downstream of the second heat exchanger 6 and upstream of the return 11. This second temperature t 2 corresponds to the temperature which the coupling liquid has at an outlet 18 of the second heat exchanger 6.
- the heating device 1 can also have a third temperature sensor 19 which is arranged in the hot water circuit 7 downstream of the second heat exchanger 6 and upstream of subsequent heat consumers. Accordingly, the third temperature sensor measures a third temperature t 3 , which prevails in the hot water circuit 7 at a further outlet 20 of the second heat exchanger 6.
- the heating device 1 further comprises a controller 21 for actuating the pump 14, the burner 2 and the changeover valve 12 or the actuator 13.
- the controller 21 is connected to the temperature sensors 15, 17, 19. Corresponding control lines and signal lines are symbolized by broken lines.
- the controller 21 is designed such that it can determine a current heat requirement of the hot water circuit 7 on the basis of the first temperature t 1 and the second temperature t 2 . Depending on this heat requirement, the controller 21 can then operate the burner 2 in a suitable manner. The aim of this control is to set a desired hot water temperature that corresponds to the third temperature t 3 .
- the heating device 1 works as follows:
- the second heat exchanger 6 can or does not essentially have to transfer any heat from the coupling liquid circuit 5 to the hot water circuit 7. Accordingly, the first temperature t 1 and the second temperature t 2 are approximately the same.
- the hot water circuit 7 has to give off hot water or heat
- comparatively cold water is fed into the second heat exchanger 6 via the hot water circuit 7 and is to be heated to the desired hot water temperature. Due to the temperature difference, the second heat exchanger 6 can now transfer heat from the coupling liquid circuit 5 to the hot water circuit 7. This results in a temperature drop in the coupling liquid circuit 5 when flowing through the second heat exchanger 6. This temperature drop is a measure of the heat requirement of the hot water circuit 7.
- the controller 21 can determine the temperature change mentioned with the aid of the first temperature sensor 15 and the second temperature sensor 17.
- the controller 21 can determine, for example, a difference between the first temperature t 1 and the second temperature t 2 . As an alternative or in addition, the controller 21 can determine an average value from the measured temperatures t 1 and t 2 . In particular, on the basis of the difference value or the mean value, the controller 21 can calculate the current heat requirement, for example, by means of a suitable calculation formula, or determine it using characteristic diagrams. The controller 21 thus determines a variable from the two temperatures t 1 and t 2 , which correlates with the current temperature requirement of the hot water circuit 7.
- the controller 21 can, by corresponding actuation of the burner 2 and / or the changeover valve 12 (or the servomotor 13), give off the heat from the burner 2 to the coupling liquid circuit 7 so that the coupling liquid circuit 5 can emit sufficient heat into the second heat exchanger 6 via its coupling branch 9 such that the heat then transferred from the second heat exchanger 6 to the hot water circuit 7 heats the water of the warm water circuit 7 to such an extent that it heats up at the outlet 20 of the second heat exchanger 6 assigned to the hot water circuit 7 essentially sets the desired hot water temperature.
- the desired hot water temperature forms one predetermined setpoint, which is derived, for example, from comfort, Ecology and economy guidelines result.
- the heating device 1 is exposed to signs of aging during its lifetime. For example, various parameters of the burner 2, the combustion chamber 3, the heat exchanger 4, 6 and also the sensors 15, 17 can change. As a result, the heat ultimately given off to the hot water circuit 7 can change over time with the same control commands from the controller 21. In order to be able to compensate for this, the third temperature sensor 19 is now provided. With the help of the third temperature sensor 19, the third temperature t 3 can be determined, which represents an actual value for the hot water temperature actually reached.
- the controller 21 can therefore carry out a target / actual comparison and evaluate any deviation that may occur and use it to correct its control signals in order to adapt the operating mode of the heating device 1 to compensate for signs of aging. Preferably, however, the controller 21 will determine a correction factor for the current heat requirement of the hot water circuit 7 on the basis of the target / actual deviation. As a result, the intervention in the control concept of the heating device 1 can be kept as small as possible.
- the third temperature sensor 19 used here is not exposed to the same aging phenomena as the temperature sensors 15 and 17 of the coupling liquid circuit 5 due to its arrangement in the hot water circuit 7. Accordingly, the third temperature t 3 determined by the third temperature sensor 19 can be used as a reference variable. Incidentally, the age-related measurement value deviations of the temperature sensors 15, 17, 19 are very small anyway and are generally negligible.
