Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Vermeidung von Schimmelpilzbefall an Innenoberflächen von Außenbauteilen.The invention relates to a method and a device for preventing mold infestation on inner surfaces of Exterior components.
Schimmelpilzbefall, insbesondere an Innenoberflächen von Außenbauteilen hat in letzter Zeit wieder vermehrt von reden gemacht. Seine Beseitigung bzw. Vermeidung führt nicht nur zu erheblichen Kosten, sondern kann insbesondere auch die Gesundheit der Bewohner gefährden. Es besteht zwar die Möglichkeit, durch Biozide oder ähnliche Mittel Schimmelpilzbefall in Räumen zu vermindern oder über gewisse Zeit zu verhindern, jedoch kann eine Gesundheitsgefährdung durch diese Produkte nicht vollständig ausgeschlossen werden. Eine Vermeidung von Schimmelpilzbildung in Gebäuden muss deshalb von den Wachstumsvoraussetzungen für Schimmelpilze ausgehen.Mold infestation, in particular on inner surfaces of external components has been talking about lately. Its elimination or avoidance leads not only at considerable cost, but in particular can also endanger the health of the residents. It is possible to by biocides or similar means Mold infestation in rooms decrease or over prevent some time, however, can pose a health hazard these products are not complete be excluded. Avoiding mold in Buildings must therefore assume the growth requirements for mold.
Temperatur und Feuchte sind die entscheidendsten Einflussfaktoren für das Pilzwachstum. Für die Gefahr eines Schimmelbewuchses auf der Innenseite einer Außenwand sind die Raumlufttemperatur und Raumluftfeuchte nur indirekt, die hygrothermischen Randbedingungen an der Innenwandoberfläche direkt maßgeblich. Dabei ist es wichtig, dass es nicht erst bei Tauwasserausfall zu Schimmelwachstum kommt, sondern temperaturabhängig bereits bei Oberflächenfeuchten oberhalb von etwa 75 % relative Luftfeuchte. Eine bedarfsgerechte Lüftung, die der Schimmelpilzvermeidung dienen soll, muss also dafür sorgen, dass diese Oberflächenrandbedingungen zumindest nicht langfristig auftreten.Temperature and humidity are the most important Influencing factors for the mushroom growth. For the Danger of mold growth on the inside of an outer wall the indoor air temperature and humidity are only indirect, the hygrothermal boundary conditions on the inner wall surface directly essential. It is important that it is not only when the condensation fails Mold growth comes, but depending on the temperature already with surface moisture above about 75% relative humidity. A needs-based Ventilation, which is intended to prevent mold, must therefore ensure that these surface boundary conditions at least do not occur in the long term.
Aus energetischer Sicht ist eine erzwungene permanente Lüftung keine Lösung, sondern diese muss in Abhängigkeit von den vor allem auch durch instationäre Befeuchtungsvorgänge (Kochen, Duschen usw.) sich an der Oberfläche einstellenden Randbedingungen erfolgen. Eine andauernde messtechnische Bestimmung der Oberflächenfeuchten und -temperaturen ist von der Sensorik und dem Aufwand her nicht vertretbar. Derzeit eingesetzte Lüftungsanlagen werden deshalb meist nur über die Luftqualität (CO2-Konzentration) gesteuert, die Feuchtelast und das Schimmelpilzrisiko bleiben dagegen unberücksichtigt.From an energetic point of view, forced permanent ventilation is not a solution, but must be carried out depending on the boundary conditions that arise on the surface, especially through transient humidification processes (cooking, showering, etc.). A continuous measurement of the surface moisture and temperature is not justifiable in terms of sensors and effort. For this reason, ventilation systems currently in use are mostly only controlled via the air quality (CO 2 concentration), while the moisture load and the risk of mold are not taken into account.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Vermeidung von Schimmelpilzbefall, insbesondere an Innenwandoberflächen von Außenbauteilen zu schaffen, die eine unnötige oder falsche Lüftung vermeiden.The invention is therefore the object based on a method and a device for avoiding Mold infestation, especially on interior wall surfaces of external components to create an unnecessary or incorrect ventilation avoid.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Hauptanspruchs und die Merkmale des Nebenanspruchs gelöst.This object is achieved by the Characteristics of the main claim and the characteristics of the secondary claim solved.
Dadurch, dass an ausgewählten Stellen der Außenwand (z.B. in den Ecken) eine künstliche Wärmebrücke eingesetzt wird, an der im Bereich der Innenoberfläche Tauwasser anfällt, das zur Steuerung einer Lüftungsvorrichtung und/oder zur Anzeige des aktuellen Lüftungsbedarfs genutzt wird, wird eine unnötige oder zum Teil auch falsche Lüftung nahezu ausgeschlossen. Befinden sich an der Innenoberfläche dieser künstlichen Wärmebrücke einfache schaltende Betauungssensoren, so können damit, solange Betauung vorliegt, Lüftungsanlagen in Gang gesetzt werden. Sobald keine Betauung mehr vorliegt, wird diese bedarfsgerecht wieder automatisch abgeschaltet.By being in selected places the outer wall (e.g. in the corners) an artificial one Thermal bridge used at which condensation occurs in the area of the inner surface, the to control a ventilation device and / or is used to display the current ventilation requirement, becomes an unnecessary one or sometimes incorrect ventilation almost impossible. Are on the inside surface of this artificial Thermal bridge simple switching condensation sensors, so can condensation as long as ventilation systems be started. As soon as there is no more condensation, these are automatically switched off again as required.
Der Vorteil der Erfindung liegt darin, dass bei Verwendung des Taupunktschalters mit Wärmebrücke die Lüftung sich bauphysikalisch richtig nur dann einschaltet, wenn die Außentemperatur unterhalb der Innentemperatur liegt und wenn die Innenraumluftfeuchte hoch ist und die Wandinnentemperaturen soweit unterhalb der Raumlufttemperaturen liegen, dass eine zu hohe Innenoberflächenfeuchte auftritt. Ein weiterer großer Vorteil liegt darin, dass keine Messfühler für die Erfassung der Luftfeuchte und Temperatur erforderlich sind. Solche Messfühler sind kostenintensiv, fehleranfällig und bedürfen ständiger Wartung.The advantage of the invention is that when using the dew point switch with thermal bridge, the ventilation is physical only switches on correctly if the outside temperature is below the inside temperature and if the indoor air humidity is high and the inside wall temperatures as far as below the room air temperatures that a too high Interior surface moisture occurs. Another big one The advantage is that there are no sensors for the detection of air humidity and temperature are required. Such sensors are expensive, prone to errors and need constant maintenance.
Durch die in den Unteransprüchen angegebenen Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen möglich.By the specified in the subclaims activities advantageous further developments and improvements are possible.
