Abstract

Technical problem of the invention The method used hitherto for structural heat insulation of intermediate floors made provision for heat insulation of 6-8 cm. In the case of a floor heating system, the heat-storage volume was restricted to the approximately 40-mm-thick screed layer. In order to make use of the off-peak power tariffs and for cost-effective usage of energy, the entire reinforced-concrete slab, including the screed, is used as heat-storage means. The storage volume permits the peak power tariff range to be bypassed without requiring a recharging time. Solution of the technical object The integration of the complete reinforced-concrete floor of the basement level or of the ground level as heat-storage means of the house is achieved by changing the heat-insulating system. The heat-insulated contour of the house is shifted outwards in an encapsulated state. Application area The application area is constituted by boiler-type floor heating systems with electric heating and an electrical direct heating system for the floor and alternatively the ceiling. The advantages lie in the exclusive use of the inexpensive off-peak power available. <IMAGE>

Description

Nutzung der Stahlbetondecken von Häusern als Wärmespeicherkapazität zum wirtschaftlichen Betrieb von Heizungen auf Nachtstrombasis.Use of the reinforced concrete ceilings of houses as heat storage capacity for economic Operation of heaters based on night current.

Bisheriger StandCurrent status

Der vorhandene und verbilligte Nachtstrom wurde bisher nur unvollkommen in die Heizungssysteme, Elektroheizung mit Wasser, als Speichermedium eingebunden.The existing and cheaper night electricity has been imperfect in the heating systems, Electric heating with water, integrated as a storage medium.

Einmal, weil der Raum- und Dämmbedarf für ein derartiges Wasserreservoir zu hoch ist und zum anderen, weil eine Speicherkapazität der 35-40 mm starken Estrichschicht im Falle der Fußbodenheizung nicht ausreichend ist, ohne Überbrückungszeiten (Aufladung), die nächste Niedertarifzeit zu erreichen.Firstly, because the space and insulation requirements for such a water reservoir are too high and for other, because a storage capacity of the 35-40 mm thick screed layer in the case of Underfloor heating is not sufficient without bridging times (charging), the next To reach low tariff time.

Das Prinzip der Elektroblockspeicherheizung kam dieser Zielstellung sehr nahe. Nur dieser Kessel mit elektrischer Direktheizung hatte einen "Speicherblock" außerhalb der Baukonstruktion und war durch die Trennung von Wasser- und Heizkreislauf mittels Wärmetauscher technisch aufwendig und wirtschaftlich nicht die effiziente Variante.The principle of electro-block storage heating came very close to this goal. Only this cauldron with direct electrical heating had a "storage block" outside of the building structure and was due to the separation of water and heating circuit by means of heat exchangers technically complex and economically not the efficient option.

Auch die elektrischen Fußbodenspeicherheizungen nutzen die Möglichkeiten nur unvollkommen. Die Heizkabel oder Heizfolien werden auf die Wärmedämmung verlegt, so daß die Wärme nachts lediglich in Estrich gespeichert werden kann.
(Annahme Haus: 10,0 m × 10,0 m × 0,04 m = 4 m³ Speichervolumen)The electric underfloor heating systems use the possibilities only imperfectly. The heating cables or heating foils are laid on the thermal insulation so that the heat can only be stored in screed at night.
(Assumption house: 10.0 m × 10.0 m × 0.04 m = 4 m³ storage volume)

Eine Nachladung dieses Systemes mit teurem Tagstrom oder in festgelegten Nachladefristen durch die jeweilige Energieversorgungsunternehmen war so vorprogrammiert.This system can be reloaded with expensive daytime electricity or within specified reloading periods The respective energy supply company was pre-programmed.

Problemproblem

In einem Niedrigenergiehaus in Holztafelbauweise soll ein kontinuierliches Wärmeerzeugungs- und Lüftungsgerät mit Wärmerückgewinnung über Wärmepumpen installiert werden. Das gesamte System, auch der Heizkessel, wird mit Strom betrieben. Das Heizmedium ist Wasser in einer Fußbodenheizung.In a low energy house in wooden panel construction, a continuous heat generation and Ventilation unit with heat recovery can be installed via heat pumps. The entire System, including the boiler, is powered by electricity. The heating medium is water in one Underfloor heating.

Die Aufgabenstellung bestand nun darin,
1. eine Wirtschaftlichkeit der Anlage, ausschließlich über Nachtstrom bzw. in Tandembetrieb, mit der Wärmepumpe zu erreichen.
2. Erkenntnisse aus dem Bau von Massivhäusern abzuleiten. The task now was
1. to achieve an economic efficiency of the system, exclusively with night power or in tandem operation, with the heat pump.
2. Derive knowledge from the construction of solid houses.

Lösungsolution

Dieses Problem konnte mit der Einbindung der Stahlbetondecken als Wärmespeicherkapazität, bei Veränderung des Systems der Wärmedämmung, technisch sicher gelöst werden.This problem could be solved by integrating the reinforced concrete ceilings as heat storage capacity Change the system of thermal insulation, technically safely solved.

I. Die wärmegedämmte Kontur des Hauses wird gekapselt nach außen verlagert. Als Volumenersatz der Wärmedämmung wird Quarzsand, auch als zusätzlicher Speicher, eingebaut.I. The thermally insulated contour of the house is encapsulated and moved to the outside. As a volume replacement quartz sand is installed in the insulation, also as an additional store.

II. Geltungsbereich sind die Fußbodenheizsysteme in Kesselbauart mit elektrischer Direktheizung als auch elektrischem Direktheizsystem des Fußbodens und alternativ der Decke. Die Vorteile liegen in der ausschließlichen Nutzung des billigen und verfügbaren Nachtstromes.II. The floor heating systems in boiler design with direct electrical heating are applicable also direct electrical heating system of the floor and alternatively the ceiling. The advantages are in the exclusive use of the cheap and available night electricity.

Das so vorhandene Speichervolumen gestattet die volle Überbrückung des Tarifbereiches, des Tages, ohne eine Nachladezeit an Tagen in Anspruch zu nehmen.The storage volume available in this way allows full coverage of the tariff area, the day, without taking days to reload.

Der Einsatz einer Wärmepumpe im Zuge einer kontrollierten Be- und Entlüftung des Hauses führt bei geringem Energieverbrauch und Vorzugstarif Wärmepumpen praktisch zu einer Mehrfachnutzung gespeicherter Energie aus Nachtstrom. The use of a heat pump as part of a controlled ventilation of the house leads with low energy consumption and preferential tariff heat pumps practically one Multiple use of stored energy from night electricity.

3. The current distortion of competition between electricity, in favor of fossil fuels, is alleviated or reduced, CO² entry is reduced.
4. The quality indicator comfort is significantly increased with the large heat storage. The low-energy houses in particular benefit here, as a rule they have no storage mass and previously had to rely on a constant supply of energy.
5. The proposal can optionally be implemented as underfloor heating or ceiling heating. In the case of ceiling heating (radiation), the intended radiators then completely cease to exist.
