    description
    Field of application of the invention The present invention relates to a system for providing hot water in buildings, the hot water being conveyed in a constant cycle in the circulation network in order to ensure that the hot water is as ready as possible at the tapping points. Larger residential buildings and administrative buildings can be considered as buildings. The hot water readiness is usually in the range of approx. 55 ° C.
    State of the art On the homepage www.jrg.ch the thermomixer «JRGUMAT» is presented, which is intended for installation in hot water circuits in order to ensure safe protection against scalding. The additional function of this fitting is to keep the circulation in the hot water circuit constantly for the purpose of constant hot water availability. In thermal solar systems in particular, it is known to use temperature controllers in combination with circulation pumps to control the system-related excess temperatures.
    The disadvantage of these previous solutions is that due to the significant circulation losses, the water heater and the heat sources in the form of boilers, heat pumps or thermal solar systems or as advanced district heating must be generously dimensioned, so that the entire system with the high equipment-technical effort only has an unsatisfactory efficiency between the energy used and usable.
    Object of the invention In view of the prior art, the invention has for its object to provide a more efficient system for providing hot water in buildings. This ensures that the hot water is ready as quickly as possible at the tapping points and minimizes circulation losses, so that the water heaters no longer have to be oversized and ultimately the efficiency of the entire system is significantly improved. Another task is to develop the system both for temperature-controllable heat sources such as boilers, heat pumps or advanced district heating - as well as in connection with solar thermal systems. Finally, it is an object of the invention to make the installation of the system as simple and time-efficient as possible. [0005] Overview of the invention [0006] The system for providing hot water circulating in buildings comprises:
    - A heat source as an energy supplier for at least one water heater;
    - a large number of withdrawal points for the hot water provided;
    - a cold water inlet pipe for feeding cold water into the system;
    - A hot water supply line to bring hot water to the tapping points; and
    - A hot water circulation line that branches off before the tapping points.
    A control device connected to the hot water circulation line and arranged between the water heater and the tapping points is intended to direct a first partial amount Mi into the hot water supply line and a remaining second partial amount M 2 from the water flowing through the hot water circulation line into the hot water heater for reheating.
    Particularly advantageous details of the system according to the invention are mentioned below : The partial quantity ratio with Mi »M 2 is set on the control device , preferably as a partial quantity ratio with Μ Ί : Μ 2 in the range of 90%: 10%.
    Between the water heater and the control device, a respectively connecting hot water supply line and hot water return line runs. The control device has a hot water line to which the hot water supply line is connected on the inflow side and the hot water supply line on the outflow side.

The hot water circulation line is connected on the inflow side to the circulation line, and the warm-up line is connected to the hot water return line on the outflow side.
    Advantageously, the control device can also have a cold water line to which the cold water inlet line on the inflow side and a cold water feed line are connected on the outflow side. The cold water supply line branches into a refill line leading to the water heater and into a safety line leading to a safety unit. The safety unit has a safety valve that reacts to excess pressure and flows into a drain.
    In the circulation line, a pump with the direction of delivery to the sub-line and to the warm-up line is installed. A first hot water meter, a backflow preventer open in the flow direction and a first balancing valve are installed as flow restrictors in the partial branch in the flow direction.

    In the warm-up line, viewed against the direction of flow, a temperature controller is positioned in front of the second hot water meter. The temperature controller has the function of increasing, at a set thereon target temperature, the first fixedly set by means of the two balancing valves dividing ratio M <M 2 falls below the set temperature of the incoming via the hot water circulation pipe water, the second subset of M 2, and when exceeding the second subset M 2 to reduce.
    The partial strand leads the warm water strand in an inflow into the warm water strand. A backflow preventer open in the flow direction is arranged in the cold water line. In the hot water line, viewed against the flow direction, a non-return valve is installed in the flow direction before the confluence.
    In the cold water line, viewed against the flow direction, a shut-off valve is arranged in front of the backflow preventer. When viewed in the direction of flow, a shut-off valve is installed in the hot water line before the junction. A shut-off valve is installed in front of the pump in the circulation line, as viewed against the flow direction.
    A cold water meter is installed in the cold water line, between the backflow preventer and the shut-off valve. In the hot water line, viewed in the direction of flow, there is a thermometer in front of the shut-off valve. In the hot water line, viewed against the flow direction, a vent valve is connected upstream of the backflow preventer. Another thermometer is installed in front of the shut-off valve in the circulation line, viewed against the flow direction.
    The heat source as an energy supplier for the at least one water heater can be based on solar chemistry; where then:
    - The partial strand flows into a thermal mixer, which is installed in the hot water strand and is intended for overtemperature protection;
    - From a cold water branch on the cold water line extends a lowering line leading into the cold water mixer;
    - In the cold water line, viewed against the direction of flow, a non-return valve is arranged in front of the cold water branch; and
    - A backflow preventer open in the flow direction is arranged in the lower branch.
    When using solar thermal, a shut-off valve is arranged in the cold water line, viewed against the direction of flow, before the cold water branch. A shut-off valve is installed in the hot water line, viewed in the direction of flow, in front of the thermal mixer. A shut-off valve is installed in the circulation line, viewed against the flow direction, in front of the pump. A cold water meter is installed in the cold water line, between the cold water branch and the shut-off valve. In the hot water line, viewed in the direction of flow, there is a thermometer in front of the shut-off valve. In the hot water line, viewed against the direction of flow, a vent valve is connected upstream of the thermal mixer. Another thermometer is installed in front of the shut-off valve in the circulation line, viewed against the flow direction.
    [0018] The control device has:
    - A first control connection for connection to the cold water inlet line and the cold water line on the inflow side;
    - A second control connection for connection to the hot water supply line and the hot water line on the outflow side;
    - A third control connection for connection to the hot water circulation line and the circulation line on the inflow side;
    - A fourth control connection for connection to the cold water line on the outflow side and the cold water supply line;
    - A fifth control connection for connection to the hot water line on the inflow side and the hot water supply line; and
    - A sixth control connection for connection to the warm-up line on the outflow side and the hot water return line.
    The system can have a heat source of the first type, in the form of a boiler - based on oil, gas, solids or electrical energy - or a district heating connection or a heat pump, and a heat source of the second type, based on solar thermal energy. Both heat sources are energy suppliers for at least a first water heater or also other water heaters. Preferably, the at least one water heater or the further water heaters each have a first and a second heating register, one of which is connected to the heat source of the first type and the other to the heat source of the second type.
    The system can have several water heaters, which are arranged on the one hand to the heat source and on the other hand to the control device in parallel connection; where then:
    - The refill line is routed to each of the water heaters;

    Exemplary embodiment [0023] With reference to the accompanying drawings, the detailed description of an exemplary embodiment of the system according to the invention for providing hot water circulating in buildings with the design variants created for this purpose is given below.
    The following definition applies to the entire further description. If reference numerals are included in a figure for the sake of clarity in the drawing, but are not explained in the directly associated description text, reference is made to their mention in the preceding or following description of the figures.
    1A and 1B This system comprises a heat source 1 of the first type, a first water heater 2, a control device 3 and, by way of example, only one removal point 0, in practice mostly a plurality of removal points 0 being present. The structural design of the system is now described when viewed from the heat source 1. The first type of heat source 1 can be a boiler - based on oil, gas or solids or electrical energy - or a district heating connection or a heat pump and its temperature can be adjusted.
    From the first source connection 11 of the heat source 1, a charging line 71 extends to a first boiler connection 21 on the water heater 2. The heating register 28 installed internally of the water heater 2 is connected to the first boiler connection 21, which leads to the second boiler connection 22 on the water heater 2 , from which the return line 72 runs to the first source connection 11 of the heat source 1. This enables circulation from the heat source 1 through the heating register 28, which thus causes the water filling in the water heater 2 to be heated. Thermometer 20 is provided to measure the temperature of the water filling.
    Due to the objective of always being able to obtain hot water at the tapping points 0 without delay, hot water which has been heated in the hot water processor 2 initially flows via the third boiler connection 23 through a hot water supply line 83 to a fifth control connection 305 of the control device 3 The hot water line 35 extends through the control device 3, namely from the fifth control connection 305 to the second control connection 302. The hot water supply line 5 runs from the second control connection 302 in the direction of the extraction point 0. Before the extraction point 0, the circulation connection 56 is installed, on the one hand the hot water supply line 5 continues to the tapping point 0 and, on the other hand, branches off as a hot water circulation line 6, which opens into the control device 3 at the third control connection 303. From the third control connection 303, a circulation line 36 extends through the control device 3, which is divided internally by the control device 3 at a circulation fork 367, namely on the one hand as a partial line 36 'at the junction 357 in the hot water line 35 and others4
    CH 712 855 A1, on the other hand, as a warm-up branch 37 branching off from the circulation branch 36 and running to the sixth control connection 306. The hot water return line 84 extends from the sixth control connection 306 to the fourth boiler connection 24.
    When hot water is consumed at one of the tapping points 0, cold water is fed via the cold water inlet line 4 and the first control connection 301 into the cold water line 34 extending through the control device 3, which leads to the fourth control connection 304 of the control device 3 and from here as a cold water supply line 41 continues. The cold water supply line 41 is divided at the cold water fork 47, namely on the one hand into the safety line 41 leading to the safety unit 9 and on the other hand into the refill line 41 'leading to the fifth boiler connection 25 of the water heater 2. The safety unit 9 consists of a safety valve 90 which reacts to overpressure and has an outlet in an outlet 91. At the T-connection 48, the refill line 41 'branches off on the one hand to the fifth boiler connection 25 and on the other hand to an emptying valve 29 for emptying the water heater 2 during service work.
    Now the existing line course in the control device 3 and the fittings installed therein are discussed in detail. The cold water inlet line 4 is brought to its first control connection 301 from outside the control device 3. Following the first control connection 301 - quasi in the direction of flow - a shut-off valve 341 is first installed in the cold water line 34, behind which a cold water meter 342 is located. A backflow preventer 343 is inserted into the cold water line 34 between the cold water meter 342 and the fourth control connection 304 - here the cold water supply line 41 is connected.
    To the outside of the control device 3 extends from its second control connection 302, the hot water supply line 5. Following the second control connection 302 - virtually counter to the direction of flow - a thermometer 350 is first installed in the hot water line 35, behind which a shut-off valve 351 is located, which is the first the junction 357 and then a backflow preventer 353 follow. In front of the fifth control connection 305 - to which the hot water supply line 83 is led - a vent valve 354 is connected to the hot water line 35.
    From outside the control device 3, the hot water circulation line 6 is brought to its third control connection 303. Following the third control connection 303 - quasi in the direction of flow - there is first a thermometer 360 in the circulation line, which is followed by a shut-off valve 361 and then a pump 365. The circulation fork 367 is located on the circulation line 36 behind the pump 365, from which, on the one hand, the partial line 36 ′ continues to the junction 357 at the hot water line 35 and, on the other hand, the warming-up line 37 branches off and leads to the sixth control connection 306. The hot water return line 84 extends from the sixth control connection 306.
    Following the circulation fork 367 - quasi in the direction of flow -, a first hot water meter 362 is first installed in the sub-branch 36 », behind which a backflow preventer 363 and then a balancing valve 366 follow as a flow limiter before the sub-branch 36 'at the mouth 357 in the Warm water strand 35 leads. In the warm-up line
    - again following the circulation fork 367 and in the direction of flow - a temperature controller 377 is installed first, followed by a second hot water meter 372, then a backflow preventer 363 and finally a balancing valve 376 as a flow limiter.
    The functions of the apparatuses present in the control device 3 will first be explained. The shut-off valves 341, 351, 361 serve to interrupt the flow in the respective line 34, 35, 36 and are e.g. closed when cleaning the water heater 2 or when servicing the pump 365. These shutoff valves 341, 351, 361 are advantageously, but not necessarily, installed within the control device 3. It would be possible to install the shut-off fittings 341, 351, 361 alternatively in the cold water inlet line 4, the hot water supply line 5 and the hot water circulation line 6. The thermometers 350, 360 could also be used outside of the control device 3 in the hot water supply line 5 or the hot water circulation line 6. Only in the fully equipped version will the cold water meter 342 be provided, on which the inflowing volume of cold water and thus the consumption of hot water can be read. The temperature controller 377 would also be unnecessary.
    The backflow preventer 343, 353, 363, 373 have the task of blocking the paths against the given flow direction, which becomes necessary when overpressure occurs, for example as a result of thermal expansion. The first and second hot water meters 362, 372 are used to measure the flow rates behind the circulation fork 367 in the partial line 36 'and in the warm-up line 37. The measured values of the flow rates are required in order to use the two balancing valves 366, 376 to achieve the desired ratio of partial amounts M <M 2 to be set, which flow from the hot water circulation dividing at the circulation fork 367 via the branch line 36 'as the first partial quantity M-ι of the junction 357 or via the heating line 37 as the second partial quantity M 2 of the hot water return line 84.
    A partial quantity ratio with Μ Ί »M 2 on the control device 3 is advantageously set for the flow, for example with M <M 2 in the range of 90%: 10%. With a ratio M <M 2 = 90%: 10%, 90% of the water flowing in the hot water circulation line 6 is fed back into the hot water supply line 5 as the first partial amount Μ Ί via the control device 3, while the remaining 10% is fed as the second partial amount M 2 via the hot water return line 84 for reheating in the water heater 2. The water flowing in the hot water circulation line 6 had cooled to below the water temperature required at the tapping points 0 due to heat losses in the line network.
    CH 712 855 A1 In its complete configuration, the control device 3 has the temperature controller 377 which is useful for dynamic readjustment. By means of the two balancing valves 366, 376, the partial quantity ratio Μ ί : Μ 2 is fixed, for example with 90%: 10%. If, for example, a setpoint temperature of 45 ° C has been set on the temperature controller 377 and the water arriving via the hot water circulation line 6 corresponds to this temperature setting, the system runs in the partial quantity ratio M <M 2 = 90%: 10%. If, as a result of interferences, such as falling hot water temperatures due to external influences, the heating requirement is greater and the water arrives at below 45 ° C, the temperature controller 377 opens more. Consequently, the partial quantity ratio Μ Ί : Μ 2 shifts in favor of an increased second partial quantity M 2 , for example Μ Ί : Μ 2 = 85%: 15%. A little more water therefore flows via the hot water return line 84 for reheating into the hot water processor 2, and less is returned to the hot water line 35 via the partial line 36 ′. Additional energy savings are achieved when the water arrives at over 45 ° C, so that the temperature controller 377 closes more and the proportion ratio shifts, for example, to M <M 2 = 95%: 5%. Then only a reduced subset M 2 is required for reheating.
    2A and 2B For a brief discussion in this embodiment, only the deviations from the variant according to the figure pair 1A and 1B are discussed, otherwise reference is made to the previous description. In addition to the existing heat source 1 of the first type, the system of the current variant now also comprises a heat source 1 'of the second type, which is based on solar thermal energy. Due to the sometimes extremely fluctuating solar radiation - depending on the time of day, weather and season - you must always provide heat sources 1,1 'of both types for a system for providing hot water. Both heat sources 1, 1 'are connected to the first water heater 2. This results in additional source connections 11 ', 12', lines 71 ', 72', boiler connections 21 ', 22' and a second heating register 28 'in the water heater 2, as well as a somewhat different equipment in the control device 3.
    The charging line 71 and the return line 72 of the heat source 1 of the first type are connected to the associated first heating register 28 in the water heater 2 via the two boiler connections 21, 22. This first heating register 28 is positioned above the second heating register 28 '. The heat source 1 'of the second type is based on solar thermal energy and has the first source connection 11' from which the charging line 71 'extends. The return line 72 'is led to the second source connection 12'. The second heating register 28 'is connected to the associated charging line 71' and return line 72 'via the two boiler connections 21', 22 '. If the solar energy is sufficiently recoverable, only the heat source 1 ′ of the second type will advantageously be used to heat the water heater 2, otherwise only additionally or only the heat source 1 of the first type.
    Due to the now integrated in the system heat source 1 'of the second type, which can lead to overheating in the water heater 2 and thus the risk of hot water at the tapping points 0 - e.g. Beyond the normal setting of 55 ° C - 3 precautions for personal protection are installed in the control device. For this purpose, the balancing valve 366 in the branch line 36 ′ is followed in the flow direction by a thermomixer 358 installed in the warm water line 35 between the shut-off valve 351 and the vent valve 354 and the backflow preventer 343. The backflow preventer 353 previously installed in FIG. 1B in the hot water line 35 is now implemented in the lowering line 36 between the thermal mixer 358 and the cold water branch 347. In the case of superheated hot water arriving at the thermomixer 358, the backflow preventer 353 and thermomixer 358 ensure the admixture of cold water to the inflow from the hot water supply line 83 and the sub-branch 36 '. The setpoint in the hot water supply line 5 is reached by the temperature reduction.
    It is again advantageous for the water arriving through the hot water circulation line 6 at the control device 3 to be set by means of a partial quantity ratio with M 2 M 2 , preferably with Μ Ί : Μ 2 in the range of 90%: 10%. Otherwise, the construction and the function of the system according to the pair of figures 2A and 2B correspond to the previous embodiment with the pair of figures 1A and 1B.
    Fig. 3 Again, this embodiment only requires discussion of the deviations from the variant according to the pair of figures 1A and 1B, otherwise reference is made to the associated description. The system now comprises a heat source 1 of the first type, a first and a second water heater 2, 2 ', a control device 3 and, by way of example, a tapping point 0. The one heat source 1 is connected in parallel to the two water heaters 2, 2', each of which is identical Thermometer 20, the five boiler connections 21-25, the heating register 28 and the drain valve 29 have. However, the parallel connection of two existing water heaters 2, 2 'results in a more branched course for the refill line 41', the first charging line 71 and the first return line 72.
    The coming from the cold water fork 47 refill line 41 »leads via the cross connection 48 'or via the T connection 48 to the respective fifth boiler connection 25 of the two water heaters 2, 2'. The cross connection 48 'and the T connection 48 also serve to install a respective drain valve 29 for the associated water heater 2', 2.
    From the first heat source 1, the first charging line 71 leads to the respective first boiler connection 21 of the relevant water heater 2, 2 '. With the two boiler connections 21, this is in the respective hot water 6
    CH 712 855 A1 2, 2 'installed first heating register 28 connected. The first return line 72 extends from the respective second boiler connection 22, which is connected to the first heating register 28 present in the relevant water heater 2, 2 ', to the first heat source 1. The hot water supply line 83 runs from the third boiler connections 23 of both water heaters 2, 2' brought together to the fifth control connection 305 of the control device 3. The hot water return line 84 passes from the sixth control connection 306 of the control device 3 to the respective fourth boiler connection 24 of the relevant water heater 2, 2 '.
    In this system, too, for the water arriving through the hot water circulation line 6 at the control device 3, a portion ratio with M-ι »M 2 can be set there, preferably with M <M 2 in the range of 90%: 10% (see 1B). Otherwise, the construction and the function of the system in FIG. 3 correspond to the first embodiment with a pair of figures 1A and 1B.
    It is also possible to design systems according to the invention with a plurality of water heaters connected in series. Due to the different temperature stratification then formed in the individual water heaters, however, the additional equipment required for a transfer system between the water heaters will have to be accepted.
    Fig. 4 With the structures according to Figs. 2A and 3 in combination, this results in an even more complex system to be discussed, each with a heat source 1, 1 'of the first and second type, two hot water conditioners 2, 2' connected in parallel. , a control device 3 and schematically with only one removal point 0. To shorten the discussion, in this exemplary embodiment, matches to previous structures are treated cursively at best, otherwise reference is made to the previous description. As in the embodiment according to FIG. 2A, the second charging line 71 'leads from the second heat source 1' to the respective second heating register 28 'in the relevant water heater 2, 2'. Equally, the second return line 72 'extends from the respective second heating register 28' in the relevant water heater 2, 2 'to the second heat source 1'.
    3, the refill line 41 'via the cross connection 48' or via the T connection 48 to the fifth boiler connections 25 of the two water heaters 2, 2 '. The hot water feed line 83 in turn extends from the two hot water conditioners 2, 2 ′, brought together to the control device 3, while the hot water return line 84 passes from the control device 3 to both hot water conditioners 2, 2 ′. The first charging line 71 leads from the first source connection 11 of the first heat source 1 to the first boiler connection 21 of the relevant water heater 2, 2 ', in which the respective first heating register 28 is installed. The first return line 72 comes from the respective second boiler connection 22 of the relevant water heater 2, 2 ′, in which the first heating register 28 is installed, and extends to the second source connection 12 of the first heat source 1.
    This complex system structure also allows a partial quantity ratio with M-ι »M 2 to be set permanently for the water arriving at the control device 3 through the hot water circulation line 6, preferably with M <M 2 in the range of 90%: 10%. When the temperature controller 377 is installed in the control device 3, the advantages of dynamic readjustment can additionally be used for an adequate adaptation of the partial quantity ratio M <M 2 . This system structure with the heat sources 1, 1 'which can be operated alternatively or together and heat water heaters 2, 2' connected in parallel is particularly efficient in terms of energy.
