  • the humidity in the walls reduces the thermal insulation of the material which is impregnated with it and promotes the formation of fungi and pests, sources of many diseases.
  • the hollow wall whose vacuum (called “slide”) is ventilated or not has been used on a large scale for many years. It tends to disappear nowadays since the use of very insulating products (polyurethane, polyisocyanurate ”) spread in the void of the wall.

  • the advantages of this method are: -accelerate the evacuation of humidity from the wall during the period of non-ventilation, the hot and dry air of the slide exerting a real pumping effect. - reduce the heat losses and the electrical energy consumption of the fan to very acceptable values. - by placing the slide very close to the interior atmosphere, the thermal capacity of the room is reduced, which makes it possible to use a much more economical heating pipe.

Abstract

Wall drainage formed by a strong but intermittent ventilation in the cavity of a double wall of a building in order to remove all the moisture which could accumulate therein; this makes it possible to apply techniques based on the small thermal inertia of the walls, which techniques are capable, in particular, of additional savings in energy of the order of 30 to 50%.

Description

L'invention concerne un type de drainage de murs d'habitation permettant d'évacuer,au fur et à mesure de sa formation,l'humi­dité qui aurait tendance à s'accumuler,quelle qu'en soit la cause. L'humidité dans les lurs diminue l'isolation thermique du maté­riau qui en est imprègné et favorise la formation de champignons et der vermine,sources de nombreuses maladies.The invention relates to a type of drainage of residential walls making it possible to evacuate, as it is formed, the moisture which would tend to accumulate, whatever the cause. The humidity in the walls reduces the thermal insulation of the material which is impregnated with it and promotes the formation of fungi and pests, sources of many diseases.

Le mur creux,dont le vide (appelé"coulisse") est ventilé ou non a été utilisé sur une grande échelle pendant de nombreuses années. Il a plutôt tendance à disparaitre actuellement depuis que s'est répandu l'usage de produits très isolants (polyuréthane,poly­isocyanurate...)placés dans le vide du mur.The hollow wall, whose vacuum (called "slide") is ventilated or not has been used on a large scale for many years. It tends to disappear nowadays since the use of very insulating products (polyurethane, polyisocyanurate ...) spread in the void of the wall.

L'inconvénient de ces systèmes d'isolation est que l'humidité, introduite dans le mur soit par accident,soit par condensation, soit par capillarité ascentionnelle... en sort très difficilement. D'autre part,pour éviter les condensations importantes,on est obligé de renoncer à des techniques,qui permettraient d'obtenir des économies d'énergie très substantielles.The disadvantage of these insulation systems is that the humidity introduced into the wall either by accident, or by condensation, or by rising capillary action ... comes out very difficult. On the other hand, to avoid significant condensation, we are forced to give up techniques, which would make it possible to obtain very substantial energy savings.

La présente invention consiste à remédier à ces inconvénients en plaçant la coulisse aussi près que possible de l'atmosphère intérieure et en la ventilant de façon énergique et très inter­mittente (par exemple,quelques minutes par heure). Les avantages de cette méthode sont:
-accélérer l'évacuation d'humidité du mur pendant la période de non-ventilation,l'air chaud et sec de la coulisse exerçant un véritable effet de pompage.
- réduire les pertes thermiques et la consommation d'énergie électrique du ventilateur à des valeurs très acceptables.
- en plaçant la coulisse très près de l'atmosphère intérieure, on réduit la capacité thermique du local,ce qui permet d'­utiliser une conduite de chauffage beaucoup plus économique.The present invention consists in remedying these drawbacks by placing the slide as close as possible to the interior atmosphere and by ventilating it energetically and very intermittently (for example, a few minutes per hour). The advantages of this method are:
-accelerate the evacuation of humidity from the wall during the period of non-ventilation, the hot and dry air of the slide exerting a real pumping effect.
- reduce the heat losses and the electrical energy consumption of the fan to very acceptable values.
- by placing the slide very close to the interior atmosphere, the thermal capacity of the room is reduced, which makes it possible to use a much more economical heating pipe.

Claims (6)

1.Ventilation intérieure d'un mur,caractérisée par un renouvel­lement intermittent de l'air, qui s'y trouve.1.Internal ventilation of a wall, characterized by an intermittent renewal of the air, which is there. 2.Ventilation suivant revendication 1, caractérisée par le fait qu'entre deux périodes consécutives de renouvellement de l'air de la coulisse,celui-ci est immobile pendant le temps néces­saire pour qu'il puisse se charger le plus possible d'humidi­té provenant du mur.2.Ventilation according to claim 1, characterized in that between two consecutive periods of renewal of the air of the slide, the latter is stationary for the time necessary for it to be able to load as much moisture as possible from the wall. 3.Ventilation suivant revendications 1 et 2,caractérisée par la réduction de la résistance à la diffusion de la vapeur d'eau entre l'atmosphère intérieure et la coulisse,en plaçant l'­isolant thermique sur la face intérieure de la paroi extéri­eure du mur.3.Ventilation according to claims 1 and 2, characterized by reducing the resistance to the diffusion of water vapor between the interior atmosphere and the slide, by placing the thermal insulation on the interior face of the exterior wall of the wall. . 4.Ventilation suivant revendications 1,2 et 3,caractérisée par la rédustion d'épaisseur de la paroi intérieure du mur exté­rieur, de manière à diminuer à la fois la résistance à la diffusion de la vapeur d'eau et la volant thermique de cette paroi.4.Ventilation according to claims 1,2 and 3, characterized by the reduction in thickness of the inner wall of the outer wall, so as to reduce both the resistance to the diffusion of water vapor and the thermal flywheel of this wall. 5.Ventilation suivant revendications 1,2,3 et 4 telle que une ventilation plus fréquente,voire même continue,soit possible occasionnellement,par exemple lorsqu'il s'agit d'assécher un mur ou de le refroidir en été.5.Ventilation according to claims 1,2,3 and 4 such that more frequent ventilation, or even continuous ventilation, is occasionally possible, for example when it is a question of drying a wall or cooling it in summer. 6.Ventilation suivant revendication 5 telle que l'inertie ther­mique diminuée dans le local comme décrit ci-dessus,puisse être déplacée,par exemple dans les fondations ou dans les caves,tout au moins en ce qui concerne sa capacité d'accumu­ler les frigories des nuits estivales.Le fluide caloporteur (porteur ici de frigories) est l'air,les conduites de celui-ci étant les coulisses des différents murs.6.Ventilation according to claim 5 such that the reduced thermal inertia in the room as described above, can be moved, for example in foundations or in cellars, at least as regards its capacity to accumulate frigories summer nights. The heat transfer fluid (carrier here of frigories) is the air, the conduits of this being behind the scenes of the different walls.
