Abstract

Porous humidity-permeable building materials with coatings which in a situation where nominal radiation factors are present have a humidity diffusion resistance of sd greater than 1 m (i.e. against the usual rule of sd less than 2 m) are humidity-uncoupled on one or both sides from the atmosphere. Significant amounts of the transmission heat losses can be reduced by the solar energy gains. The coatings on the outside consist of coating systems with ceramic parts in an aqueous acrylic emulsion.

Description

Die Erfindung betrifft die Nutzung von Baustofffeuchte in Bauteilen zur Minderung der Wärmeverluste bei beheizten Räumen durch Verbesserung der solaren Wärmegewinne an opaken Bauteilen.The invention relates to the use of building material moisture in components to reduce heat loss in heated rooms by improving the solar heat gains on opaque components.

Bei Räumen, welche unterschiedlich zur Umgebung temperiert sind, insbesondere bei beheizten Räumen, treten an den opaken Bauteilen durch Wärmetransmission Wärmeverluste auf. Zusatzlich kann Strahlung einwirken, welche (z.B. durch Sonneneinstrahlung) die Wärmeströme beeinflussen kann. Bei üblichen beheizten Räumen können Sonnenenergiegewinne verbucht werden, welche bei lichtdurchlässigen Bauteilen beachtlich sein können, bei opaken Bauteilen aber gewöhnlich gering sind und deshalb i.a. auch nicht rechnerisch berücksichtigt werden. Die Nutzung von Sonnenenergie mittels lichtdurchlässiger Bauteile ist aus raumklimatischen Gründen u.a. im Zusammenhang mit dem stark schwankenden Außenklima und Wärmebedarf von Sommer und Winter begrenzt (Treibhauseffekt). Da die Wärmetransmission durch opake Bauteile, insbesondere durch Außenwände wegen des großen Flächenanteils an der wärmetauschenden Hüllfläche, einen erheblichen Anteil der Wärmeverluste ausmacht, besteht Bedarf darin, die Verluste durch geeignete Maßnahmen zu reduzieren. Bisherige Maßnahmen durch zusätzliche lichtdurchlässige Außenverkleidungen an opaken Wänden sind raumklimatisch und bautechnisch schwierig sowie sehr kostenaufwendig. Insbesondere bei Altbauten sind ubliche Maßnahmen zur Minderung der Transmissionswärmeverluste unter den verschiedensten Aspekten schwierig und kostenaufwendig durchzuführen, so daß auch das Anbringen von üblichen Dämmschichten oftmals nicht infrage kommt. Hier ist ein anderer platzsparender Lösungsansatz erforderlich. Ziel der Erfindung ist, unter Verwendung von Beschichtungen einen geeigneten Konstruktionsaufbau herzustellen, der, ohne daß Nachteile fur die Bausubstanz entstehen, feuchtegekoppelte Wärmetransporte ermöglicht, die die Transmissionswärmeverluste erheblich mindern. Bisherige Maßnahmen zur Begrenzung des Wärmeverlustes an Außenbauteilen zielen auf folgende Maßnahmen ab:

  • Minimierung der Wärmeleitung, durch trockene Bauteile und Verwendung von porösen Baustoffen mit einem großen Anteil Gasporen (Luft oder ggf. Teilvakuum), welche durch eine geringe Rohdichte gekennzeichnet sind.
  • Minimierung der Wärmestrahlung dadurch, daß an den Oberflächen Materialien mit einem geringen Emissionsgrad, z.B. Metallschichten, verwendet werden.
  • Minimierung der Luftkonvektion dadurch, daß Bauteilschichten (luft)dicht sind und Hohlräume nur kleine Abmessungen besitzen.
  • Zusätzlich bei lichtdurchlässigen Bauteilen, z.B. Fenstern, Energiegewinne durch Sonnenstrahlung dadurch, daß das Material selektive Strahlungsdurchlässigkeit aufweist.
In rooms with different temperatures, especially in heated rooms, heat loss occurs on the opaque components due to heat transmission. In addition, radiation can act, which can influence the heat flows (eg due to solar radiation). In the case of conventional heated rooms, solar energy gains can be recorded, which can be considerable in the case of translucent components, but are usually low in the case of opaque components and are therefore generally not taken into account in the calculation. The use of solar energy by means of translucent components is limited due to climatic reasons, among other things in connection with the strongly fluctuating outside climate and heat requirements in summer and winter (greenhouse effect). Since the heat transmission through opaque components, in particular through outer walls, because of the large area share of the heat-exchanging envelope surface, accounts for a considerable proportion of the heat losses, there is a need to reduce the losses by means of suitable measures. Previous measures by additional translucent outer cladding on opaque walls are climatic and structural engineering difficult and very costly. In the case of old buildings in particular, customary measures for reducing transmission heat losses are difficult and costly to carry out in a wide variety of aspects, so that the application of customary insulation layers is often out of the question. Another space-saving approach is required here. The aim of the invention is to use coatings to produce a suitable construction which, without causing disadvantages for the building structure, enables moisture-coupled heat transport, which considerably reduces the transmission heat losses. Previous measures to limit heat loss on external components aim at the following measures:
  • Minimization of heat conduction through dry components and the use of porous building materials with a large proportion of gas pores (air or partial vacuum), which are characterized by a low bulk density.
  • Minimization of heat radiation by using materials with a low emissivity, eg metal layers, on the surfaces.
  • Minimization of air convection by the fact that component layers (air) are tight and cavities have only small dimensions.
  • In addition, in the case of translucent components, for example windows, energy gains from solar radiation in that the material has selective radiation permeability.

Die v.g. Maßnahmen werden z.T. dadurch realisiert, daß die Baustoffe trocken und diffusionsoffen gehalten werden. Wegen des Dampfdruckgefälles zwischen den beidseits des Außenbauteils anliegenden Klimata wird ein entsprechend kleiner Wasserdampfdiffusionswiderstand an der Seite des Bauteils mit dem kleinen Dampfdruck gefordert, der in Abhängigkeit vom Wasserdampfdiffusionswiderstand auf der Bauteilseite mit dem größeren Dampfdruck bemessen wird. Im allgemeinen werden zur Vermeidung von Blasenbildung an der Seite des kleineren Dampfdruckes Wasserdampfdiffusionswiderstände gefordert von sd < 2 m. Die Ausführungen zeigen, daß feuchte Bauteilschichten als Nachteil angesehen werden, weil zum einen Wasserporen schlechter dämmen als Gasporen und zum anderen durch den Feuchtetransport in Richtung des Dampfdruckgefälles erhebliche Wärmetransporte möglich sind. Dieses zeigt, daß Feuchtigkeit dazu geeignet ist, größere Wärmemengen zu transportieren. Die Aufgabe der Erfindung besteht nun darin, diesen Transportmechanismus für Energiegewinne zu nutzen, indem durch Strahlung im allgemeinen und Sonnenstrahlung im besonderen die Richtung des Feuchtestroms und des anteiligen Wärmestroms umgekehrt wird. The v.g. Measures are partly realized in that the building materials kept dry and open to diffusion. Because of the Vapor pressure gradient between the two sides of the outer component adjacent climates will have a correspondingly low water vapor diffusion resistance on the side of the component with the small one Vapor pressure required, which depends on the water vapor diffusion resistance on the component side with the higher vapor pressure is measured. In general, to avoid Bubbles on the side of the lower vapor pressure Water vapor diffusion resistances required by sd <2 m. The executions show that damp component layers as a disadvantage be considered because, on the one hand, water pores are less well insulated as gas pores and on the other hand through the transport of moisture in Significant heat transport in the direction of the vapor pressure gradient possible are. This shows that moisture is suitable for to transport larger amounts of heat. The object of the invention is now this transport mechanism for energy gains to be used by radiation in general and Solar radiation in particular the direction of the moisture flow and of the proportional heat flow is reversed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß durch eine geeignete Schichtenfolge an Bauteilen aus porösen und relativ feuchteunempfindlichen Baustoffen, welche durch relativ dampfdichte Schichten von den angrenzenden Feuchteeinflüssen abgekoppelt werden, innerhalb der Baukonstruktion Feuchtepotentiale gezielt beeinflußt werden, die z.B. unter Einwirkung von Sonneneinstrahlung den Transmissionswärmestrom in der Gesamtbilanz mindern oder sogar umkehren. Ein wesentlicher Vorteil des Verfahrens liegt darin, daß die bereits vorhandenen Bauteile aus porösen Baustoffen von Altbauten für die Verwendung in der erfindungsgemäßen Baukonstruktion geeignet sind. Nachfolgend soll die Erfindung an einem Beispiel näher erlautert werden. Dabei besteht die erfindungsgemäße Baukonstruktion aus einem porösen Baustoff, welcher einseitig durch eine Beschichtung der Firma Thermo-Shield GmbH & Co KG, Wackenbergstraße 78-82, 13156 Berlin, vom Außenklima feuchte-entkoppelt ist. Versuche mit einem modifizierten Plattengerat (Poensgengerät) ergaben unter Strahlungs- und Feuchteeinfluß eine beachtliche und rasche Minderung des stationären Warmestroms im Vergleich zu der selben unbeschichteten Probe.This object is achieved in that a suitable layer sequence on components made of porous and relative moisture-resistant building materials, which by relative vapor-tight layers from the adjacent moisture influences be uncoupled within the building construction moisture potentials can be influenced in a targeted manner, e.g. under influence of solar radiation the transmission heat flow in the Reduce overall balance or even reverse. An essential one The advantage of the method is that the existing ones Components made of porous building materials from old buildings for use are suitable in the construction according to the invention. Below the invention is explained in more detail using an example become. The construction according to the invention consists of a porous building material, which is coated on one side from Thermo-Shield GmbH & Co KG, Wackenbergstraße 78-82, 13156 Berlin, moisture-decoupled from the outside climate is. Try a modified plate device (Poensgen device) resulted under the influence of radiation and moisture a remarkable and rapid reduction in stationary heat flow compared to the same uncoated sample.
