Description

Die Erfindung betrifft ein Verfahren zur Steuerung eines Gerätesystems, um durch effektive Nutzung insbesondere regenerativer Energien den Wärmebedarf eines Hauses abzudecken. Das Gerätesystem ist aus an sich bekannten Teilsystemen aufgebaut, im weiteren Baugruppen genannt, die jedoch erfindungsgemäß so gekoppelt sind, daß mit dem neuen Verfahren die einzelnen Baugruppen derart gesteuert werden, daß eine maximale Ausnutzung der regene­ rativen Energien erfolgt.The invention relates to a method for controlling a device system by effective Use of regenerative energies in particular to cover the heating requirements of a house. The Device system is made up of subsystems known per se, in the further assemblies called, but are coupled according to the invention so that with the new method individual assemblies are controlled so that maximum use of the rain ratative energies.

Die für ein Passivhaus taugliche Technik zur Nutzung regenerativer Energiequellen besteht derzeitig aus folgenden Baugruppen:
The technology suitable for a passive house for the use of renewable energy sources currently consists of the following components:

  • - Solarkollektoren verschiedener Ausführung- Various types of solar collectors
  • - Erdwärmespeicher- geothermal storage
  • - Erdwärmetauscher- geothermal heat exchanger
  • - Wärmepumpen- heat pumps
  • - Abwasserwärmetauscher/Abwasserreinigung- Waste water heat exchanger / wastewater treatment
  • - Luftwärmetauscher- air heat exchanger
  • - intelligente Wärmespeicher- intelligent heat storage
  • - Photovoltaikanlage- photovoltaic system
  • - Brennstoffzellen.- fuel cells.

Diese Baugruppen sind untereinander aber wenig gekoppelt und nutzen nicht gegenseitig und konsequent die Synergieeffekte. Mit dem Home Electronic System (Häuser heute, Heft 2/99, S. 24, 25) von Siemens wird der Versuch unternommen, verschiedene Wärme- und Energieverbraucher über ein Bussystem zu koppeln und das Zusammenwirken der Verbraucher zu organisieren. Damit wird ein Weg beschritten, Verbrauch und Aufkommen an Energie zu koppeln. Eine konsequente Verknüpfung der Baugruppen zur effektiven Nutzung regenerativer Energien ist damit nicht gegeben.However, these modules are not coupled to one another and do not use each other and consequently the synergy effects. With the Home Electronic System (houses today, issue 2/99, pp. 24, 25) Siemens is trying to different heat and Coupling energy consumers via a bus system and the interaction of consumers to organize. This is a way of increasing consumption and amount of energy couple. A consequent linkage of the assemblies for the effective use of regenerative ones There is no energy with it.

Mit der Entwicklung neuer Isolationen der Gebäudehülle und dem Einsatz regenerativer Energiequellen sinkt der Wärmebedarf eines Hauses erheblich. Häuser mit Passiv-Standard benötigen nur noch ca. 10 kWh/m2a. Die zuzuführende Heizleistung auch am kalten Wintertag (-15°C) sinkt unter 1 kW. Die Auswahl und Kopplung unterschiedlicher regenerativer Energiequellen ist entscheidend für die kontinuierliche Senkung der Wärmeheizleistung. Bei diesen geringen Heizleistungen ist es wichtig, die Gerätesysteme möglichst wärmeverlustfrei zu koppeln. Andererseits sollen die Haustechniksysteme nicht überdimensioniert werden, um Inve­ stitionskosten zu sparen.With the development of new insulation of the building envelope and the use of regenerative energy sources, the heat requirement of a house drops considerably. Houses with the passive standard only need approx. 10 kWh / m 2 a. The heat output to be supplied even on cold winter days (-15 ° C) drops below 1 kW. The selection and coupling of different renewable energy sources is crucial for the continuous reduction of the heat output. With these low heating capacities, it is important to couple the device systems with as little heat loss as possible. On the other hand, the home automation systems should not be oversized in order to save investment costs.

Es ist daher die Aufgabe der Erfindung, ein Haustechniksystem zu schaffen und die Baugruppen so zu koppeln, daß die Möglichkeit besteht, mit einer äußeren Elektroenergiequelle als Notversorgung (Netz oder Photovoltaik) und Trinkwasser auszukommen. It is therefore the object of the invention to create a building services system and the assemblies to couple so that there is the possibility of using an external source of electrical energy Emergency supply (grid or photovoltaic) and drinking water.  

Die einzelnen Baugruppen sollen so gesteuert werden, daß eine maximale Ausnutzung der regenerativen Energien erfolgt.The individual modules should be controlled so that maximum utilization of the regenerative energies.

Erfindungsgemäß wird die Aufgabe wie folgt gelöst, wobei hinsichtlich der grundlegenden erfinderischen Gedanken auf den Patentanspruch 1 verwiesen wird. Die weitere Ausgestaltung der Erfindung ergibt sich aus den Patentansprüchen 2 bis 5.According to the invention the object is achieved as follows, with regard to the basic inventive thought is referred to claim 1. The further design the invention results from the claims 2 to 5.

Ergänzend soll angemerkt werden, daß mit dem erfindungsgemäßen Verfahren der Heizwärme­ bedarf eines Einfamilienhauses auf 5 kWh/m2a gesenkt werden kann. Die Bereitstellung der Energie ist im Sommerbetrieb mit 2,5 kWh/d und im Winterbetrieb mit 4 kWh/d für einen 4- Personenhaushalt möglich. Die Heizungs- und Warmwasserbetriebskosten sinken damit auf maximal 0,65-1,04 DM/d.In addition, it should be noted that with the method according to the invention, the heat required for a family home can be reduced to 5 kWh / m 2 a. The energy can be provided in summer operation with 2.5 kWh / d and in winter operation with 4 kWh / d for a 4-person household. The heating and hot water operating costs thus drop to a maximum of DM 0.65-1.04 / d.

Die Erschließungskosten für diese Häuser sinken, da nur noch Elektroenergie, Trinkwasser und Nachrichtenkabel herangeführt werden müssen, zumal auch eine vollbiologische Hauskläranlage integriert werden kann. Durch Nachschaltung einer Abwasseranlage an den Abwasserwärmetau­ scher wird 50% des aufbereiteten Wassers im Haus genutzt und etwa 50% kann dem Regenwasserspeicher zugeführt werden. Das Verbleiben des Wassers im Kreislauf senkt ebenfalls die Wärmeverluste.The development costs for these houses decrease because only electrical energy, drinking water and Communication cables must be brought in, especially since a fully biological domestic sewage treatment plant can be integrated. By connecting a wastewater system to the wastewater heat rope 50% of the treated water is used in the house and about 50% can do it Rainwater storage tanks are supplied. Remaining water in the circuit lowers also the heat losses.

Die Erfindung soll nunmehr anhand eines Ausführungsbeispiels näher erläutert werden.The invention will now be explained in more detail using an exemplary embodiment.

Die Abb. 1 zeigt das erfindungsgemäße Gerätesystem und die informelle und physische Kopplung der einbezogenen Baugruppen. Fig. 1 shows the device system according to the invention and the informal and physical coupling of the modules involved.

A mathematical model is used, analogous to the heat requirement calculation of a house. The house user has the option of storing his user behavior on the computer 1 . The most important energy consumers, hot water, drinking water and room air exchange rate, can be calculated.

Eine Vielzahl von Entscheidungen kann getroffen werden.From this data, an energy balance volume / consumption can be calculated on a daily basis be and the difference triggers the control tactics that the loading state of the Heat storage considered.

So z. B.

  • - Solarzelle hohe Temperatur, Kurzzeitwärmespeicher voll ⇒ Beladung des Erdwärmespeichers- Solar cell high temperature, short-term heat storage full ⇒ Loading of the geothermal storage
  • - Solarzelle niedrige Temperatur, Kurzzeitwärmespeicher nicht voll ⇒ Nutzung der Restwärme der Solarsole über die Wärmepumpe, Beladung des Kurzzeitwärmespeichers- Solar cell low temperature, short-term heat storage not full ⇒ Use of the residual heat of the solar brine via the heat pump, loading the Short-term heat storage

Grundsätzlich sind sehr viele Steuervarianten möglich, deren übergeordnete Steuerstrategie von dem Prinzip ausgeht:
In principle, a large number of tax variants are possible, the overriding tax strategy of which is based on the principle:

Durch die Koordinierung der Wärmeverbraucher und die Vermeidung von gleichzeitigem Verbrauch
By coordinating heat consumers and avoiding simultaneous consumption

  • - Waschmaschine/Geschirrspüler/Badewanne/Erhöhung der Raumtemperatur- Washing machine / dishwasher / bathtub / increase in room temperature

kann die Wärmeentnahme aus dem Wärmespeicher vergleichmäßigt werden und so wird garantiert, daß mit geringer Wärmepumpenleistung die notwendige Wärme kostengünstig bereit­ gestellt wird.the heat removal from the heat storage can be evened out and so guarantees that the necessary heat is available inexpensively with low heat pump output is provided.

Das geschilderte neue Gerätesystem unter Verwendung eines Steuerrechners mit Logic-Block kann mit dem bekannten Home Elektronik System oder einem Bussystem leicht gekoppelt werden. Eine Fernbedienung über Telefon, z. B. bei vorzeitigem Urlaubsabbruch (hochfahren auf Nutzungstemperatur der Hausumluft, Warmwasserspeicher maximal) ist jederzeit möglich. Es wurde gefunden, daß bereits ein Erdwärmespeicher von 100 m2 ausreicht, um die Solarausfalltage von ca. 50 Tagen/ Winter zu kompensieren. The described new device system using a control computer with a logic block can be easily coupled with the known home electronics system or a bus system. A remote control via telephone, e.g. B. in the event of an early holiday termination (increase to the temperature at which the house air circulates, maximum hot water tank) is possible at any time. It was found that a geothermal storage of 100 m 2 is sufficient to compensate for the solar failure days of approximately 50 days / winter.

Die Nutzung der Abwasserwärme senkt den Warmwasser-Wärmebedarf um 50-66%. Die Mehrfachnutzung der Solarkollektoren für Kurzzeit- und Langzeitspeicher erhöht den Solarwärmeertrag etwa um 40% über das Jahr. Neben den energetischen Gesichtspunkten entsteht im Haus ein höheres Behaglichkeitsgefühl durch gleichbleibende Klimabedingungen. Der Wegfall von Kaltstrahlern bzw. Zugluft läßt die Behaglichkeit schon bei einem Haustemperaturniveau von 20°C zu, welches ebenfalls den Wärmebedarf des Hauses senkt. Die sinnvolle, vor allem auch räumliche Gestaltung der Leitungen und Steuerelemente und deren hohe Wärmedämmung sind die Voraussetzungen für die hohe energetische Wirksamkeit des Systems bei geringstem Energieverbrauch.The use of waste water heat reduces the hot water heat requirement by 50-66%. The Multiple use of the solar collectors for short-term and long-term storage increases the Solar heat yield about 40% over the year. In addition to the energetic aspects there is a higher feeling of comfort in the house due to constant climatic conditions. The Elimination of cold spots or drafts means that the comfort level is already there House temperature level of 20 ° C, which also lowers the heat requirement of the house. The sensible, above all spatial design of the lines and control elements and their high thermal insulation are the prerequisites for the high energetic effectiveness of the Systems with the lowest energy consumption.
