- the invention also relates to a method to provide hot domestic water, in which a fluid in one Primary circuit is running, providing warm or hot fluid to a device and a conveyor that conveys the fluid, the process water to be heated the heat from the fluid runs in a secondary circuit, in a heat exchanger the primary circuit is transferred to the process water in the secondary circuit, the conveyor is regulated, a temperature sensor in the primary and / or secondary circuit is provided and when regulating the conveyor this when certain threshold values of temperature and / or are reached the temperature gradient on the temperature sensor and / or time-dependent this conveyor is switched on and / or switched off.
- the hot domestic water is conventionally provided by means of a Heat source in a domestic hot water tank, a so-called boiler, who also takes on the task of intermediate energy storage.
- a heat exchanger for example a plate heat exchanger
- warm Water from a storage and then cooled water back in returned the memory on the one hand.
- cold process water or drinking water fed into the heat exchanger and from there warm drinking water promoted a tap to the user.
- Such a hot water preparation based on the flow principle is known, for example from DE 40 35 115 C2.
- the construction proposed there requires quite a lot of sensor technology and very sensitive Components, for example flow switches, to a corresponding suitable To bring about regulation.
- the heat exchangers are directly connected to the Storage, i.e. a device that provides warm or hot fluid, connected.
- the heat exchanger is therefore water on the primary side high temperature level, because these high temperature levels of, for example, 90 ° C are not only reached in the solar storage, but also are also welcome there.
- direct forwarding leads the very hot fluid also at high temperatures at the heat exchanger transfer surfaces, which may be undesirable there Limescale can result.
- the object of the present invention is to overcome such problems in the generic arrangements and methods in the heat exchanger to avoid.
- this object is achieved in that a return of cooled fluid after passing through the heat exchanger in the primary circuit into a region of the primary circuit between the device providing the warm or hot fluid and the heat exchanger, this returned fluid with the warm or hot Fluid is mixed from the device to achieve a certain temperature at the entrance of the heat exchanger.
- a type of bypass is provided in the primary circuit. Originally from the device with the warm or hot fluid, so fluid originating in the storage has after passing through of the heat exchanger in a significant part of its stored heat the secondary circuit is released and has cooled significantly. in the State of the art, this cooled fluid is now in turn stored returned. According to the invention, the bypass line makes it controllable Share of this fluid, however, again within the primary circuit fed into the area in front of the heat exchanger, but after the storage tank.
- the feeding and mixing of the two quantities of fluid upstream of the heat exchanger is preferably done by a thermostatic valve. This can make a special precise definition of the proportions of the two fluid quantities in the mixture respectively.
- An arrangement is particularly favorable when the heat exchanger is outside the insulation of the device providing the warm or hot fluid is arranged. This will change the temperature inside the heat exchanger additionally from the temperature in which the warm or decoupled hot fluid providing device.
- This facility is included preferably a buffer memory.
- the bypass according to the invention with the preferred one Thermostatic valve can ensure that the heat exchanger inlet in the primary circuit one critical for calcification and also for heat transfer Avoid unnecessary high temperature above 65 ° C becomes.
- the conveyor device provided in the primary circuit in particular a pump is regulated. This leaves the required hot water tap rate in the secondary circuit and the required volume flow in the primary circuit optimize.
- the return in the primary circuit in the memory can be placed close to the cold water temperature, the electrical power consumption the pump is moving at a low level.
- Switching on and regulating the pump output for the Water heating can also be proposed as in DE 196 19 566 C1 via temperature sensors.
- This circuit can also be used in others Shape happen.
- a corresponding temperature sensor can either in the primary circuit, the existing one there, especially at the outlet of the Tapping the heat exchanger prevailing temperature of the fluid and with this or work with the temperature gradient. It is also possible by skillful use of the data of a temperature sensor in the Secondary circuit, especially at the outlet of the heat exchanger in the secondary circuit, to perform such control.
- Such a circulation line just wins and especially then Advantage when switched on and / or off via a temperature sensor and is regulated.
- this regulation is possible with one and the same temperature sensor controls the conveyor in the primary circuit, preferably by a temperature sensor adjacent to the outlet of the heat exchanger in the secondary circuit.
- Sanitary hot water circulation pipes in buildings are known from DE 94 16 613 U1.
- a circulation line there is also a circulation line there arranged parallel to a hot water pipe, one Evaluation device is provided, which when a pump starts up Water withdrawal at the tap an induction voltage in the pump evaluates. When a threshold value of the induction voltage is reached the pump is separated from the evaluation device to the general voltage network connected and switched off after a certain time.
- Such a concept is for use with heat exchangers however not provided.
- the invention provides an arrangement and regulation of hot water production created in the flow principle, which is also a circulation control can include.
- a circulation control can include.
- the primary circuit 10 begins on the left with a device that is warm or provides hot fluid, here a buffer store 11. From this buffer store 11 leads a line 12 to a heat exchanger 5. After Pass through the heat exchanger 5 and the release of the thermal energy in the same runs the fluid back into the primary circuit 10 via an output side Line 13 to the device 11, ie the buffer memory.
- a conveyor device 14 in particular a pump is provided.
- This conveyor 14 is relatively close to Output of the heat exchanger 5 is arranged.
- a temperature sensor 17 Between the conveyor 14 and the heat exchanger 5 is also a temperature sensor 17 arranged, so the temperature and / or the temperature gradient of the fluid in the primary circuit 10 practically immediately after leaving of the heat exchanger 5 measures.
- This branch line 19 leads back inside of the primary circuit 10 in the area of line 12 from the buffer memory 11 to the heat exchanger 5. It opens into a mixing valve 15.
- This mixing valve 15 is in particular a thermostatic valve. Be him on the one hand fluid cooled by the branch line 19 from the heat exchanger 5, but on the other hand also through the line 12 hot fluid from the Buffer memory 11 supplied. These two apart from the temperature identical fluids are mixed so that a desired predetermined Temperature of below 65 ° C arises at the outlet of the mixing valve 15. Through the further course of line 12, this becomes the desired temperature possessing fluid then in turn fed to the heat exchanger.
- the secondary circuit 20 on the right-hand side of the illustration in FIG. 1 begins with a cold water supply line 22 with which cold process water (drinking water, wash water, etc.) is fed to the heat exchanger 5.
- the heat energy of the primary circuit 10 running in countercurrent is received in the heat exchanger 5.
- the process water After passing through the heat exchanger 5, the process water in turn leaves it and flows through an outlet-side line 23 to the hot water withdrawal point, the tap.
- Funding in the secondary circuit can in principle take place in that the cold water supply takes place under pressure and the hot water withdrawal point by a tap may block this pressure.
- the hot water or actual process water leads in line 23 there is a temperature sensor 27.
- This temperature sensor 27 is as possible arranged close to the outlet of the heat exchanger 5.
- a circulation line 40 is also provided in the secondary circuit 20.
- the circulation line 40 branches off adjacent to the tap 28 leads back to the cold water access line 22 immediately before the heat exchanger 5.
- a further circulation pump 44 is in the circulation line 40 intended.
- a temperature sensor 47 which measures the temperature in the circulation line 40, in particular between the circulation pump 44 and the inflow into the cold water inlet 22.
- the purpose of this measure is to cool the water after a certain period of time not to flow in line 23 from the tap 28, since the Consumption hot water and not cooled domestic water. He would probably just use this cooled process water let the line run.
- the one currently flowing out of the heat exchanger 5 Water is warm because it has thermal energy from the primary circuit 10 added.
- the length of the line 23 and the flow behavior are known so that the circulation pump 44 is very precise can be controlled in such a way that exactly when they are heated, as desired Process water at the tap 28 also flow out there can.
- the temperature sensor 17 sets the standby temperature, among other things the conveyor 14 fixed. If this falls below a certain threshold, so the conveyor 14 for a settable period X switched to full power. The period will be several seconds. It is chosen to be so long that the cooled fluid in the primary circuit 10 from the heat exchanger 5 by hot fluid from the upper area the device 11, ie from the upper memory area, replaced and is returned to the lower memory area.
- the pulse function also works to a desired behavior of the system: repeated switching on the pump after an interruption of a period Y leads to a heating of the domestic water in the heat exchanger 5 without that unnecessary mixing of warm fluid in the primary circuit 10 the upper area of the device 11 in the lower return.
- the temperature sensor registers this process 27 as a change in temperature.
- the domestic water immediately in the Heat exchanger 5 is at least slightly warmer than that previously on the temperature sensor 27 upcoming process water.
- the pump output Via a temperature comparison of a setpoint on the temperature sensor 27 and an actual value on the temperature sensor 27 the pump output will then be between 0 and maximum Power regulated so that the actual value at temperature sensor 27 is equal to Setpoint is.
- the temperature of the warm provided by the device 11 or hot fluids in the primary circuit 10 can fluctuate extremely, depending on the season or other external conditions. Such fluctuation can between 50 ° C and 95 ° C. Also the tap rates for the domestic water can fluctuate greatly, for example between 0 and 15 Liters per minute. These strong fluctuations lead to very high requirements the control accuracy of the hot water pump.
- Temperature changes on the temperature sensor 27 due to heat loss or heat conduction are significantly less than changes in temperature due to flow movements in the primary circuit 10 or in the secondary circuit 20. Accordingly, the temperature difference is preferably chosen to be so large that that the value is only exceeded with flowing media.
- This pump can be switched off, for example, if in a switchable period XX no or only defined slight temperature changes between two threshold values or defined positive temperature changes be registered at the temperature sensor 27.
- the switch-off can also take place if a sensor 17 at the output of the heat exchanger 5 in the primary circuit 10 in the line 13 to the device 11 a temperature above a predetermined target value is measured becomes.
- a relatively high temperature means that the warm fluid in the primary circuit 10 in the heat exchanger 5 no longer cooled because there is no more hot water tapping.
- the temperature sensor 27 can also be used to switch on the Circulation pump 44 can be used.
- the tap at the tap 28 only opened briefly, the temperature sensor 27 registers this first as already described above by a change in temperature, first by an increase in temperature, then by a decrease in temperature.
- These temperature changes switch adjustable for Z seconds the circulation pump 44.
- the period is preferably chosen so that in the secondary circuit 20, the hot water is just up to the tap 28 is promoted. The user of the system therefore has a short opening of the tap at the tap 28 and a short Then pause immediately via hot water at tap 28, without the To drain the line empty.
- the circulation pump 44 is adjustable Period YY, for example for 10 minutes, blocked. This period will chosen so that in the secondary circuit 20, the cooling of the hot water in the lines 22 and 23 last as long as the temperature of the domestic water is still perceived as pleasant. Basically, of course, could circulation is also blocked for a certain period of time by means of a clock become.
- a temperature sensor 47 in the circulation circuit 40 can additionally also the temperature in the circulation return after the tap or taps 28 detect and the circulation pump 44 above a certain Always block the temperature at temperature sensor 47.
- the invention provides an arrangement and regulation of a Water heating created in a continuous flow principle, which also has a circulation control can include. With simple means it is ensured that if necessary, water of the desired temperature quickly at the taps is available, however temperature losses and water consumption are minimized and by an intelligent arrangement of simple and reliable and cost-effective sensors in particular reliable but nevertheless inexpensive solution is created.
