Definitions
- DE 102014210745 A1 discloses a heating system comprising at least one heating circuit, a fluid circulating in the heating circuit, at least one heat generator, a first valve and a second valve. It is suggested that there is a pressure sensor between the first valve and the second valve.
- the invention is based on a method for operating a heater, with the heater heating a flow of heat transfer fluid, with an adjustable diverting valve directing the flow of heat transfer fluid to a first heat consumer and/or a second heat consumer, the diverting valve being used in at least a first method step when a heat request for the first heat consumer is present, directs the flow of heat transfer fluid, in particular completely, to the first heat consumer.
- a heater is understood here in particular as a device for heating a room and/or a flow of drinking water.
- the heater includes in particular a heat generator for heating a heat transfer fluid flow, in particular a heating water flow; an adjustable diverter valve for directing the heat transfer fluid flow to a first heat consumer and/or a second heat consumer; a line system of line sections for receiving and conducting the flow of heat transfer fluid and for fluidly connecting the fluid-contacted components of the heating device; a control/regulation unit for controlling and/or regulating at least the diverting valve.
- a heat generator is to be understood here in particular as a heat generator fired with gaseous, liquid or solid fuel or an electrically heated heat generator.
- the line system includes, in particular, two hydraulically parallel lines, one of which runs through the first heat consumer and another runs through the second heat consumer.
- the diverting valve is arranged at a hydraulic branch in the flow of the line system, where the heat transfer fluid stream coming from the heat generator, in particular heated, flows according to a valve position through hydraulically parallel line sections to the first heat consumer and/or the second heat consumer.
- the line system also includes a hydraulic junction in the return of the line system, where the line sections coming from the first heat consumer and/or second heat consumer meet again, so that the heat transfer fluid stream coming from the first heat consumer and/or second heat consumer, which has in particular been cooled, flows back to the heat generator.
- the flow of heat transfer fluid can be circulated through the line system in particular by means of a pump.
- the diverting valve can be designed as a switching valve for switching between two discrete valve positions—to the first heat consumer or to the second heat consumer.
- the diverter valve as a mixing valve for continuous or gradual adjustment with at least one intermediate hydraulic valve positions, in particular with a plurality or Variety of intermediate valve positions between the two aforementioned discrete valve positions (valve end positions) may be formed.
- Operating the heating device is understood here to mean in particular switching on, switching off, modulating active components and monitoring components and ensuring functions of the heating device.
- a heat consumer is to be understood here in particular as a device for using the heat transported in the heat transfer fluid flow.
- the first heat consumer is a drinking water heat exchanger, in particular a plate heat exchanger, for heating a drinking water stream.
- the first heat consumer is in particular a component of the heating device.
- the second heat consumer is a space heating circuit for heating a room, the space heating circuit in particular comprising at least one space heater that can be controlled and/or shut off by a valve, in particular a thermostatic valve or shut-off valve.
- the second heat consumer is not part of the heater; the heater includes, in particular, connection devices for hydraulically connecting the heater to the second heat consumer.
- a heat request is to be understood here in particular as a request from a user to the heating device with regard to the provision of a hot drinking water flow or space heating, with the heat request resulting, for example, from a comparison of an actual temperature of a domestic hot water flow and/or a room with an assigned target temperature of the domestic hot water flow and/or or of the room.
- a first method step is to be understood here in particular as the at least partial fulfillment of a heat requirement with regard to the provision of the warm drinking water stream.
- the heated heat transfer fluid flow flows in particular completely to the first heat consumer and heats the drinking water flow.
- the diverting valve is adjusted to a valve position in which a hydraulic connection is created between the heat generator and the first heat consumer.
- the diverter valve is in particular adjusted to a valve end position, in which a hydraulic connection is created between the heat generator and the first heat consumer and a hydraulic connection between the heat generator and the second heat consumer closes.
- the first method step is carried out for a maximum permissible duration T at the longest.
- the first method step ends when the user has finished requesting heat or after the maximum permissible duration T at the latest.
- the subsequent step lasts for a short duration D.
- the flow of heat transfer fluid is at least partially directed to the second heat consumer.
- the diverting valve is adjusted to a valve position in which a hydraulic connection is created between the heat generator and the second heat consumer.
- a hydraulic connection between the heat generator and the first heat consumer can remain in place during the subsequent step.
- the valve position during the subsequent step can be an exclusive connection between the heat generator and the second heat consumer.
- the next step takes place independently of a heat request from the second heat consumer, in particular even if there is no heat request from the second heat consumer.
- the subsequent step can serve in particular to reduce or, in particular, to completely compensate for any pressure difference in the heat transfer fluid that may build up during the first method step at the diverter valve between a side of the diverter valve that faces the heat generator and a side of the diverter valve that faces the second heat consumer.
- the fact that the diverter valve directs the flow of heat transfer fluid at least partially to the second heat consumer in a subsequent step can mean that the flow of heat transfer fluid flows at least partially to the second heat consumer in the subsequent step.
- this can also mean that in the next step the diverter valve closes the fluid connection of the Heat transfer fluid flow at least partially opens from the heat generator to the second heat consumer without causing the heat transfer fluid to flow.
- the latter can be the case, for example, when another valve in/on the second heat consumer is closed and therefore does not permit flow.
- a first method step is activated again if there is still a heat request for the first heat consumer.
- a further first step is activated.
- the provision of the warm drinking water flow can involve a sequence of at least two or more first method steps, each followed by a subsequent step.
- an assumed, particularly longer-lasting provision of a drinking water stream heated by the heat generator is divided into regular intervals of duration T (first method step), each followed by a short intermediate interval of duration D (following step).
- a warm drinking water flow is provided during the entire tapping time and pressure equalization is regularly achieved in the heat transfer fluid between the side of the diverter valve facing the heat generator and the side of the diverter valve facing the heating circuit.
- the fact that the provision of the domestic hot water flow is divided up means in particular that the drinking water flow continues to flow unchanged in terms of quantity during the entire tapping time, but the heating of the drinking water flow in the first heat consumer during the subsequent step can be briefly reduced for the duration D, since the heat transfer fluid flow is at least partially directed to the second heat consumer.
- a temperature fluctuation in the domestic hot water flow due to a possibly reduced heat transfer fluid flow at the first heat consumer occurs in particular due to the thermal inertia of the components involved in domestic hot water heating (first heat consumer and adjacent line sections) does not occur or is at least very small.
- a heating output of the heater and/or a volumetric flow of the heated heat transfer fluid flow are additionally adjusted during the subsequent step, in particular increased, so that a proportion A of the heat transfer fluid flow during the subsequent step is unchanged in quantity and temperature compared to the immediately preceding first method step for the first heat consumer flows.
- the first method step ends as soon as the heat requirement for providing the warm drinking water flow ends, or as soon as the maximum permissible duration T ends.
- the diverting valve opens a first fluid path from the heat generator to the first heat consumer, in particular completely, and the diverting valve closes a second fluid path from the heat generator to the second heat consumer, in particular completely.
- the diverting valve at least partially opens the second fluid path from the heat generator to the second heat consumer.
- Opening the first fluid path from the heat generator to the first heat consumer means in particular directing the heat transfer fluid flow to the first heat consumer.
- Closing the second fluid path from the heat generator to the second heat consumer means that different pressures can form in the heat transfer fluid upstream of the diverting valve and downstream of the diverting valve in the direction of the second heat consumer.
- Opening the second fluid path from the heat generator to the second heat consumer means in particular closing the heat transfer fluid flow to direct the second heat consumer; this allows the pressures to equalize upstream of the diverter valve and downstream of the diverter valve in the direction of the second heat consumer.
- the first fluid path hydraulically connects the line section coming from the heat generator to the line section leading to the first heat consumer.
- the second fluid path hydraulically connects the line section coming from the heat generator to the line section leading to the second heat consumer.
- the first fluid path and the second fluid path are formed in particular in/on the deflection valve and can be opened and/or closed, in particular at least partially, by adjusting the deflection valve.
- the fact that the diverter valve directs the flow of heat transfer fluid at least partially to the second heat consumer in a subsequent step can mean that the diverter valve in the subsequent step at least partially opens a fluid path from the heat generator to the second heat consumer, so that via this fluid path a pressure equalization takes place in the heat transfer fluid upstream of the diverter valve and can take place downstream of the diverter valve.
- the short duration D of the open second fluid path from the heat generator to the second heat consumer ensures in particular at least partial pressure equalization, preferably complete pressure equalization, between a side of the diverter valve facing the heat generator and a side of the diverter valve facing the second heat consumer.
- the maximum permissible duration T of the first method step takes on a value
- the duration T ensures, in particular, that any pressure difference in the heat transfer fluid that may build up at the diverter valve during the first method step between a side of the diverter valve facing the heat generator and a side of the diverter valve facing the second heat consumer assumes only a small value. This small pressure difference can easily be equalized during the duration D of the subsequent step.
- a total heat transfer fluid flow is understood here in particular to mean the heat transfer fluid flow heated in the heat generator, in particular the heat transfer fluid flow conveyed by the pump, which flows to the first and/or second heat consumer.
- the entire heat transfer fluid stream flows to the first heat consumer.
- the entire heat transfer fluid flow flows to the second heat consumer.
- the degree of valve opening ensures in particular that at least part of the heat transfer fluid flow is directed to the second heat consumer.
- the degree of valve opening also ensures, in particular, that in the subsequent step a pressure equalization can take place in the heat transfer fluid upstream of the diverter valve and downstream of the diverter valve.
- a further proposal relates to a heating device for heating a room and/or a flow of drinking water, comprising a heat generator for heating a flow of heat transfer fluid, in particular a flow of heating water; an adjustable diverter valve for directing the heat transfer fluid flow to a first heat consumer and/or a second heat consumer; a control/regulation unit for controlling and/or regulating at least the diverter valve; wherein the control/regulating unit is designed to adjust the diverting valve in a first method step when there is a heat demand for the first heat consumer such that it directs the heat transfer fluid flow, in particular completely, to the first heat consumer.
- control/regulation unit be designed to adjust the diverting valve in a subsequent step, when the first method step ends, in such a way that it directs the flow of heat transfer fluid at least partially to the second heat consumer, with the first method step at most a maximum permissible duration T, with the subsequent step lasting a short duration D.
- a control/regulation unit is to be understood here as a control unit or a regulation unit which, in particular using a computer program, electrical and/or electronic circuit components and/or incoming sensor signals, has a controlling or regulating effect on at least the diverting valve and is designed to carry out the method.
- the control/regulation unit also serves in particular to control or regulate the heat generator and/or the pump.
- the control/regulation unit is designed to activate a first method step again after duration D has elapsed if there is still a heat request for the first heat consumer. In this way, in particular, a longer-lasting heat requirement from the first heat consumer can be met.

- a pump 106 which is arranged in particular in a return line of the heat generator 102, is used for circulation of the heat transfer fluid flow 104 in a conveying direction 105 (arrows).
- An adjustable diverter valve 108 arranged in particular in a supply line of the heat generator 102 is used to direct the heat transfer fluid flow 104 to a first heat consumer 110 and/or a second heat consumer 112.
- the diverter valve 108 is at a branch 111 of the Flow line to two hydraulically parallel lines (line sections 114a and 114b) of a line system 114 arranged.
- the diverting valve 108 can also be arranged at a junction 113 of the two hydraulically parallel lines (line sections 114a and 114b) in the return line.
- the diverting valve 108 can in particular be a switchable three-way valve 108 with two discrete valve end positions.
- the line system 114 comprising line sections 114a, 114b, 114c and others, is used to receive and conduct the heat transfer fluid stream 104 and for fluid-conducting connection of the fluid-touched components (102, 106, 108, 110, 112) of the heater 100.
- the line system 114 includes in particular a line section 114c coming from the heat generator 102 and opening out at the upstream inlet of the diverter valve 108; a line section 114a leading from the diverter valve 108 to the first heat consumer 110 and further to the junction 113, which connects to a downstream outlet of the diverter valve 108; and a line section 114b leading from the diverting valve 108 to the second heat consumer 112 and further to the junction 113, which—hydraulically parallel to the aforementioned line section 114a—connects to a further outlet of the diverting valve 108 on the downstream side.
- the pump 106 is arranged in particular in the return line of the heat generator 102, between the junction 113 and the heat generator 102.
- the pump 106 is arranged in particular in the flow line of the heat generator 102, between the heat generator 102 and the branch 111.
- the pump 106 can convey the heat transfer fluid stream 104--in particular as a function of a valve position of the diverting valve 108--to the first heat consumer 110 and/or to the second heat consumer 112.
- a control/regulation unit 116 is used to control and/or regulate at least the diverting valve 108.
- the control/regulating unit 116 is designed to adjust the diverting valve 108 in a first method step S1 when there is a heat requirement for the first heat consumer 110 that it directs the flow of heat transfer fluid 104, in particular completely, to the first heat consumer 110.
- the control/regulating unit 116 is further designed to adjust the diverting valve 108 in a subsequent step SF, when the first method step S1 ends, so that the heat transfer fluid flow 104 directs at least partially to the second heat consumer 112.
- the first method step S1 lasts at most a maximum permissible duration T.
- the subsequent step SF lasts a short duration D.
- the control/regulation unit 116 is also configured to reactivate a first method step S1 after the duration D has elapsed if there is still a heat request for the first heat consumer 110 is present.
- the control/regulating unit 116 can also be provided to control or regulate the heat generator 102, in particular a heating output of the heat generator 102, and/or the pump 106, in particular a delivery rate of the pump 106.
- the control/regulating unit 116 is connected to the diverter valve 108, the heat generator 102 and the pump 106 by means of signal lines 117.
- the first heat consumer 110 is a drinking water heat exchanger 110, in particular a plate heat exchanger 110, for heating a drinking water flow 2.
- a cold drinking water flow 2 enters the drinking water heat exchanger 110 through a cold water line 118, is heated in the drinking water heat exchanger 110 by the heat transfer fluid flow 104, and exits into a hot water line 120, which leads to a tap (point of use), not shown.
- the first heat consumer 110 is in particular a component of the heater 100.
- the second heat consumer 112 is a room heating circuit 112 for heating a room 1, with the room heating circuit 112 here having a controllable by a valve 122, in particular a thermostatic valve 122 or shut-off valve 122 and/or space heaters 124 that can be shut off.
- the second heat consumer 112 is not part of the heater 100 here.
- the heater 100 includes connection devices 126 for hydraulically connecting the heater 100 to the second heat consumer 112.
- any pressure differences in heat transfer fluid 104 between a side of diverter valve 108 facing heat generator 102 and a side of diverter valve 108 facing second heat consumer 112 are reduced or, in particular, completely compensated for.
- Such pressure differences can occur during operation of the heater 100 when the valve 122 in the space heating circuit 112 closes or is closed while the diverter valve 108 has a first fluid path from the heat generator 102 to the first Heat consumer 110 opens and a second fluid path from the heat generator 102 to the second heat consumer 112 closes.
- a partial volume 104b of heat transfer fluid is enclosed in the line section 114b between the diverter valve 108 and the valve 122 in the space heating circuit 112 .
- this heat transfer fluid partial volume 104b now cools down, it contracts in accordance with its thermal spatial expansion coefficient. Without the subsequent step SF, the heat transfer fluid partial volume 104b could experience a significant drop in pressure in the particularly rigid line section 114b between the two valves 108, 122.
- the proposed method ensures that no pressure difference or only a small pressure difference can build up at diverter valve 108, and that a force acting on diverter valve 108 and caused by the pressure difference present at diverter valve 108 is always smaller than one actuating force that can be applied by a valve drive 109 of the diverter valve 108 for an adjustment of the diverter valve 108. If the force caused by a pressure difference was greater than an actuating force of the valve actuator 109, the valve actuator 109 could not overcome this force and the diverter valve 108 could not be adjusted. A service call by a service technician may be required to rectify such a fault. Optionally, diverter valve 108 and/or valve 122 could also be damaged.
- the valve 122 in the space heating circuit 112 in particular a valve 122 of the space heater 124, can be designed as a thermostatic valve 122 and close automatically when its ambient temperature increases. Designed as a shut-off valve 122, it can be closed by a user of the room 1.
- FIG. 2 shows a diagram of an excerpt from a process sequence during operation of the heating device 100.
- a time profile t is shown on the X axis (abscissa axis).
- a heat request for the first heat consumer 110 begins, for example triggered by tapping a domestic hot water stream 2.
- the heat request for the first heat consumer 110, in particular the Tapping of domestic hot water flow 2 is represented by a thick black line that jumps from a process activity 0 (heat request and/or tapping inactive) to a process activity 1 (heat request and/or tapping active).
- the heat generator 102 heats the heat transfer fluid flow 104.
- a first method step S1 begins, in which the diverter valve 108 is adjusted so that the heat transfer fluid flow 104 flows to the first heat consumer 110, where the drinking water flow 2 is heated.
- the brief subsequent step SF begins, in particular immediately following the first method step S1.
- the diverting valve 108 is adjusted in such a way that the fluid path from the heat generator 102 to the second heat consumer 112 opens. This achieves a pressure equalization in the heat transfer fluid 104 between the side of the diverting valve 108 facing the heat generator 102 and the side of the diverting valve 108 facing the second heat consumer 112 .
- the subsequent step SF ends.
- a further first method step S1 begins, in particular immediately after the subsequent step SF, in particular for heating the drinking water flow 2.
- Such a sequence of first method steps S1 for heating drinking water and subsequent steps SF for pressure equalization is continued alternately until the heat request for the first heat consumer 110 ends at time t-2. For example, tapping of hot water 2 is terminated at time t-2. This also ends the first method step S1, shown here after a period of time X ⁇ T.
- the heater 100 if there is a heat request from the second heat consumer 112, can move to a second method step (not shown here). in particular for the provision of space heating. If there is no heat request at time t-2, heating device 100, in particular heat generator 102, can switch off. It is advisable to switch the diverting valve 108 to a position towards the second heat consumer 112 outside of times when the first heat consumer 110 is requesting heat, for example outside of times when domestic hot water is being drawn off to adjust the open valve position (not shown here). Thus, no pressure difference can build up in the heat transfer fluid 104 between a side of the diverting valve 108 facing the heat generator 102 and a side of the diverting valve 108 facing the second heat consumer 112 .
