- the energy-efficiently heated hot water from the flow VL can be used for showering, for example.
- the instantaneous water heater 140 also gives the user the option of tapping hot water at a higher temperature. This can be necessary at a sink 230 in the kitchen, for example, to wash dishes, for example. In this relatively rare case, reheating by the flow heater can be used, without giving up the general energy efficiency of the home station (in connection with the central water heating).

- a first temperature sensor can be provided in the line for hot water downstream of the heat exchanger 130 . The temperature detected by the first temperature sensor is used to control the first valve 121.
- the valve 121 can be used to stop a volume flow in the direction of the heating flow HVL.
- a commercially available fitting can optionally be provided between the hot water line WW and, for example, a shower, which has both the hot water line WW and a cold water connection KWA, in order to enable showering at a lower temperature than the hot water in the hot water line WW .
- the first to fifth exemplary embodiment relates to a home station with a flow heater 140 with an inlet temperature sensor 141 and an outlet temperature sensor 142 and a temperature sensor 113 behind the mixing point (flow heater and bypass) in the hot water pipe WW.
- the sixth to tenth exemplary embodiment shows a continuous-flow heater 140 with only one inlet temperature sensor 141.
- the outlet temperature sensor 142 can be removed.

- a motor valve 128 is provided on the input side of the valve unit 160, so that cold water can be added to the hot water from the hot water line WW in the valve unit 160 if required.
- a motor valve 129 is provided in or at the mixing point MP in order to add cold water from the cold water connection KWA into the hot water pipe WW, for example at the mixing point M, as required.
- the thirteenth to eighteenth exemplary embodiment is advantageous because, for example, only one line is provided between the respective tap and the valve unit, which supplies water at the desired temperature. So that one can commercially available fittings with a hot water connection and a cold water connection can be dispensed with.

Das Haustechniksystem gemäß der Erfindung ist als Wohnungsübergabestation ausgestaltet und mit einer zentralen Warmwasserbereitung gekoppelt.The building services system according to the invention is designed as an apartment transfer station and is coupled to a central water heating system.
Der Wärmeübertrager 130 weist einen ersten und zweiten Temperatursensor 131, 132 auf. Die Ventile 121, 122 werden entsprechend der durch den ersten oder zweiten Temperatursensor 131, 132 erfassten Temperatur gesteuert.The
Somit wird das Wasser aus dem Vorlauf VL beispielsweise einer zentralen Wärmepumpe 150 in dem Wärmeübertrager 130 vorerwärmt und ggf. durch den Durchlauferhitzer 140 nacherwärmt, um auf die gewünschte Solltemperatur des Warmwassers am Warmwasserausgang WW zu kommen. Die Solltemperatur des Warmwassers kann durch einen Benutzer eingestellt werden. Das Ventil 123 in dem Bypass 20 kann dazu dienen, das durch den Wärmeübertrager 130 vorerwärmte Warmwasser an dem Durchlauferhitzer vorbeizuleiten, wenn die gewünschte Warmwassertemperatur bereits vorhanden ist.Thus, the water from the flow VL, for example, a
Am Warmwasserausgang des Wärmeübertragers 130, d. h. in oder an der Leitung 13, ist ein erster Temperatursensor 111 vorgesehen. Ein zweiter Temperatursensor 112 ist in oder an dem Wärmeübertrager 130 vorgesehen. Ein dritter Temperatursensor 113 kann in oder an der Leitung 16, d. h. an der Warmwasserleitung WW vorgesehen sein. Der Durchlauferhitzer 140 weist einen Eingangstemperatursensor 141 und einen Ausgangstemperatursensor 142 auf.At the hot water outlet of the
Das erste Ventil 121 wird in Abhängigkeit der durch den ersten Temperatursensor 111 ermittelten Temperatur gesteuert. Das zweite Ventil 122 wird gemäß der durch den zweiten Temperatursensor 112 ermittelten Temperatur gesteuert.The
Beispielsweise ist die Ausgangstemperatur des Wärmeübertragers 130 ca. 38°C. In dem ersten Ausführungsbeispiel von
Die Wohnungsstation 100 gemäß dem vierten Ausführungsbeispiel kann insbesondere auf der Wohnungsstation gemäß dem ersten Ausführungsbeispiel beruhen. Somit ist ein dritter Temperatursensor 113 in der Warmwasserleitung vorgesehen. Der Durchlauferhitzer 140 kann dann entsprechend der durch den Temperatursensor 113 erfassten Temperatur geregelt bzw. gesteuert werden.The
Zusätzlich dazu kann ein fünftes Ventil 125, insbesondere ein Motorventil, in dem Durchlauferhitzer 140, insbesondere in seinem Gehäuse, vorgesehen sein. Somit kann der Durchfluss des Durchlauferhitzers 140 mit dem fünften Ventil 125 geregelt bzw. gesteuert werden.In addition to this, a
Ferner kann ein viertes Ventil (z. B. ein Motorventil) in der Leitung 16 hinter dem Mischpult MP vorgesehen sein.Furthermore, a fourth valve (e.g. a motor valve) can be provided in the
In einer Wohnung können verschiedene Verbrauchseinheiten 200 vorgesehen sein. Die Verbrauchseinheiten können beispielsweise eine Badewanne 210, eine Dusche 220 oder ein Waschbecken 230 darstellen. Der erste Ausgang 162 kann über eine Leitung 17 mit einer Badewanne 210, der zweite Ausgang 163 kann über eine Leitung 18 mit einer Dusche 220 und der dritte Ausgang 164 kann über eine Leitung 19 mit einem Waschbecken 230 gekoppelt sein. Des Weiteren kann die Wohnungsstation ein sechstes und siebtes Ventil 126, 127 aufweisen, welche jeweils als Motorventile ausgestaltet sein können. Das sechste Motorventil 126 kann mit einem Kaltwasseranschluss sowie mit dem ersten Ausgangsanschluss 162 gekoppelt sein. Das siebte Ventil 127 kann mit dem Kaltwasseranschluss sowie mit dem zweiten Ausgangsanschluss 163 der Ventileinheit 160 gekoppelt sein. Entsprechend den Einstellungen der Motorventile 126, 127 kann Kaltwasser aus dem Kaltwasseranschluss KWA in die Leitungen am ersten und zweiten Anschluss 162, 163 der Ventileinheit fließen.Various consumption units 200 can be provided in an apartment.

Die Wohnungsstation 100 gemäß der Erfindung weist einen Kaltwasserzulauf KWZ sowie einen Vorlaufanschluss VL und einen Rücklaufanschluss RL auf. Der Vorlaufanschluss VL und der Rücklaufanschluss RL sind mit einer zentralen Warmwasserbereitung wie beispielsweise einer Wärmepumpe (150) gekoppelt. Somit kann beispielsweise eine zentrale Wärmeaufbereitung für mehrere Wohnungen in einem Gebäude vorgesehen sein. In jeder Wohneinheit ist dann eine Wohnungsstation als Schnittstelle zwischen der zentralen Warmwasserbereitung und den Warmwasserzapfstellen in der Wohneinheit und einer Heizanlage in der Wohneinheit vorgesehen.The
Die Wohnungsstation 100 weist ferner einen Heizungsvorlauf-Anschluss HVL, einen Heizungsrücklauf-Anschluss HRL, einen Kaltwasseranschluss KWA und eine Warmwasserleitung WW auf. Das vorerwärmte Wasser aus der Vorlaufleitung VL kann sowohl für den Heizungsvorlauf HVL als auch für die Warmwasserleitung WW verwendet werden. Der Wärmeübertrager 130 kann einen Temperatursensor 112 aufweisen, welcher die Temperatur des Kaltwassers KW erfasst. Anhand dieser Temperatur kann ein Zweiwegeventil zwischen dem Wärmeübertrager und dem Rücklauf RL vorgesehen sein. Die Temperatur des Wassers in dem Vorlauf VL kann beispielsweise 38°C betragen. Somit kann das Wasser am Eingang des Durchlauferhitzers ebenfalls 38°C betragen. Entsprechend der gewünschten Solltemperatur kann der Durchlauferhitzer 140 dann eine Nacherwärmung des Wassers vornehmen. Der Durchlauferhitzer 140 kann einen Eingangstemperatursensor 141 und optional einen Ausgangstemperatursensor 142 aufweisen. Parallel zu dem Durchlauferhitzer kann ein Bypass 20 vorgesehen sein. Entsprechend der gewünschten Solltemperatur kann der Durchlauferhitzer 140 aktiviert werden und/oder der Bypass 20 kann Wasser durchlassen, um Warmwasser an dem Warmwasseranschluss WW bzw. der Leitung 16 bereitstellen zu können.The
Die erfindungsgemäße Wohnungsstation 100 ist vorteilhaft, weil damit sehr energieeffizient das durch den Vorlauf VL zur Verfügung gestellte Warmwasser (welches beispielsweise durch eine Wärmepumpe erzeugt wird) nur im Bedarfsfall mittels des Durchlauferhitzers weiter nacherwärmt werden kann. Mittels der erfindungsgemäßen Wohnungsstation kann das energieeffizient erwärmte Warmwasser aus dem Vorlauf VL beispielsweise zum Duschen verwendet werden. Je weniger der Durchlauferhitzer 140 nacherwärmen muss, desto energieeffizienter ist die Wohnungsstation. Durch den Durchlauferhitzer 140 wird jedoch auch dem Anwender die Möglichkeit gegeben, Warmwasser mit einer höheren Temperatur zu zapfen. Dies kann beispielsweise an einem Waschbecken 230 in der Küche notwendig sein, um beispielsweise Geschirr zu spülen. Für diesen relativ seltenen Fall kann dann auf eine Nacherwärmung durch den Durchlauferhitzer zurückgegriffen werden, ohne dabei die allgemeine Energieeffizienz der Wohnungsstation (im Zusammenhang mit der zentralen Warmwasserbereitung) aufzugeben.The
Gemäß einem Aspekt der vorliegenden Erfindung weist die Wohnungsstation eine Anzeigeneinheit und ein Bedienelement auf. Mittels der Anzeigeneinheit und dem Bedienelement kann ein Anwender die gewünschte Solltemperatur einstellen. Die Anzeigeneinheit und das Bedienelement können als Fernbedienung und/oder als eingebautes Anzeigenelement ausgestaltet sein.According to one aspect of the present invention, the home station has a display unit and an operating element. A user can set the desired target temperature by means of the display unit and the operating element. The display unit and the operating element can be designed as a remote control and/or as an integrated display element.
Mit der erfindungsgemäßen Wohnungsstation kann somit eine gradgenaue Einstellung der Warmwassertemperatur erfolgen.With the home station according to the invention, the hot water temperature can thus be set to the exact degree.
Gemäß einem Aspekt der vorliegenden Erfindung kann das Ventil 123 in dem Bypass beispielsweise ab einem Volumen von 7 I pro Minute geöffnet werden.According to one aspect of the present invention, the
Gemäß einem Aspekt der vorliegenden Erfindung kann die maximale Wassertemperatur am Ausgang des Durchlauferhitzers 45°C oder eine andere eigestellte zulässigeTemperatur betragen. Dies dient beispielsweise als Schutz beim Duschen, damit der Anwender sich nicht verbrüht.In accordance with one aspect of the present invention, the maximum water temperature at the outlet of the instantaneous water heater may be 45°C or some other set allowable temperature. This serves, for example, as protection when showering, so that the user does not scald himself.
Der Durchlauferhitzer 140 gemäß einem Aspekt der vorliegenden Erfindung kann so ausgestaltet sein, dass er bis zu der maximal möglichen Temperatur (beispielsweise 60°C) gradgenau die gewünschte Warmwassertemperatur liefert.The
In dem ersten bis siebzehnten Ausführungsbeispiel kann auf ein Dreiwegeventil wie in
Optional kann gemäß dem ersten Ausführungsbeispiel zwischen der Warmwasserleitung WW und beispielsweise einer Dusche eine handelsübliche Armatur vorgesehen sein, welche zum einen die Warmwasserleitung WW als auch einen Kaltwasseranschluss KWA aufweist, um ein Duschen auch mit einer niedrigeren Temperatur als dem Warmwasser in der Warmwasserleitung WW zu ermöglichen.According to the first exemplary embodiment, a commercially available fitting can optionally be provided between the hot water line WW and, for example, a shower, which has both the hot water line WW and a cold water connection KWA, in order to enable showering at a lower temperature than the hot water in the hot water line WW .
Das erste bis fünfte Ausführungsbeispiel bezieht sich auf eine Wohnungsstation mit einem Durchlauferhitzer 140 mit einem Eingangstemperatursensor 141 und einem Ausgangstemperatursensor 142 sowie einem Temperatursensor 113 hinter dem Mischpunkt (Durchlauferhitzer und Bypass) in der Warmwasserleitung WW. Das sechste bis zehnte Ausführungsbeispiel zeigt einen Durchlauferhitzer 140 lediglich mit einem Eingangstemperatursensor 141. Der Ausgangstemperatursensor 142 kann entfernt werden. Hierbei können die Temperaturwerte des Temperatursensors 113 hinter dem Mischpunkt in der Warmwasserleitung WW zur Steuerung oder Regelung des Durchlauferhitzers 140 verwendet werden.The first to fifth exemplary embodiment relates to a home station with a
In dem elften bis siebzehnten Ausführungsbeispiel weist die Wohnungsstation ferner eine Ventileinheit 160 auf. Die Ventileinheit 160 ist hinter einem Mischpunkt M der Wohnungsstation und den Warmwasserzapfstellen 210, 220, 230 vorgesehen.In the eleventh to seventeenth exemplary embodiments, the home station also has a
In dem elften Ausführungsbeispiel von
In dem zwölften Ausführungsbeispiel von
In dem dreizehnten bis siebzehnten Ausführungsbeispiel ist ein Motorventil 129 in oder an dem Mischpunkt MP vorgesehen, um bei Bedarf Kaltwasser aus dem Kaltwasseranschluss KWA in die Warmwasserleitung WW beispielsweise am Mischpunkt M bei Bedarf hinzuzufügen.In the thirteenth to seventeenth exemplary embodiments, a
Das dreizehnte bis achtzehnte Ausführungsbeispiel ist hierbei vorteilhaft, weil beispielsweise zwischen der jeweiligen Zapfstelle und der Ventileinheit lediglich eine Leitung vorgesehen wird, welche Wasser mit der gewünschten Temperatur liefert. Damit kann auf eine handelsübliche Armatur mit einem Warmwasseranschluss und einem Kaltwasseranschluss verzichtet werden. Vielmehr kann beispielsweise eine mittels der Anzeigeneinheit und den Bedienelementen eingegebene Solltemperatur gradgenau abgegeben werden. Erfindungsgemäß ist somit eine einzige Wasserleitung zwischen der Ventileinheit und einer Zapfstelle vorgesehen.The thirteenth to eighteenth exemplary embodiment is advantageous because, for example, only one line is provided between the respective tap and the valve unit, which supplies water at the desired temperature. So that one can commercially available fittings with a hot water connection and a cold water connection can be dispensed with. Rather, for example, a setpoint temperature entered by means of the display unit and the operating elements can be output to the degree. According to the invention, a single water line is thus provided between the valve unit and a tap.
In dem siebzehnten Ausführungsbeispiel, welches auf dem sechzehnten Ausführungsbeispiel beruht, ist kein Ventil zwischen dem Mischpunkt MP und der Ventileinheit vorgesehen. Dafür ist die Ventileinheit 123 in dem Bypass B als Motorventil ausgestaltet.In the seventeenth embodiment, which is based on the sixteenth embodiment, no valve is provided between the mixing point MP and the valve unit.
