Abstract
This patent of invention relates to a hygro- adjustable wall base ventilation system (3) intended both for accelerating the process of transporting humidity outwards and decreasing the level reached by the rising damp. The said system comprises a mechanical ventilation device (8) which is activated by a control module (7), the latter being associated to two probes (5 and 6), temperature and relative humidity, respectively, which measure the hygrothermal conditions of the system inlet (1) and exhaust (2) air. The ventilator (8) has a variable speed and is hygro-adjustable, so it is started whenever the inlet steam pressure is lower than the exhaust steam pressure, as well as when the inlet relative humidity is higher than a preset value. The system is applicable in all cases where it is to be installed at a height above that of the ground-water table and it is aimed at limiting the level reached by the rising damp in historical buildings /monuments.

PARA TRATAMENTO DA HUMIDADE ASCENSIONAL" FOR TREATMENT OF ASCENSIONAL HUMIDITY "
Âmbito do invento Scope of the invention
O presente invento refere-se a um sistema higro- regulável de ventilação da base das paredes, constituído por canais periféricos enterrados, adjacentes à base das paredes do edifício, cuja circulação de ar é forçada por um ventilador accionado por sondas que medem o diferencial de pressão de vapor do ar à entrada e à saída do sistema. The present invention relates to a thermoregulable wall-base ventilation system consisting of buried peripheral channels adjacent to the base of the building walls, the air circulation of which is forced by a fan driven by probes measuring the differential of the wall. vapor pressure of air at system inlet and outlet.
Este sistema é aplicável em situações em que a cota de implementação do sistema se encontra acima do nível freático e tem por objectivo transportar vapor de água para o exterior acelerando o processo de secagem das paredes, diminuindo o nível atingido pela humidade ascensional (capilaridade) . This system is applicable in situations where the implementation quota of the system is above the groundwater level and its purpose is to transport water vapor to the outside accelerating the drying process of the walls, decreasing the level reached by the humidity (capillarity).
Trata-se de um sistema vocacionado para o tratamento de paredes de alvenaria em contacto com o solo de construções históricas/monumentos .
Técnica anterior It is a system dedicated to the treatment of masonry walls in contact with the ground of historic buildings / monuments. Prior art
Existem várias técnicas para eliminar ou minimizar a humidade em paredes de edifícios. There are several techniques for removing or minimizing moisture in building walls.
Em paredes de edifícios antigos a introdução de barreiras físicas apresenta limitações como vibrações e instabilidade e é aplicável apenas em alvenarias resistentes com juntas regulares. In old building walls the introduction of physical barriers has limitations such as vibration and instability and is only applicable to sturdy masonry with regular joints.
Por outro lado, a introdução de barreiras químicas implica a execução de uma barreira contínua em toda a espessura da parede o que é dificilmente concretizável em paredes muito espessas e muito heterogéneas como são as paredes de edifícios antigos. On the other hand, the introduction of chemical barriers implies the execution of a continuous barrier throughout the wall thickness, which is difficult to achieve in very thick and very heterogeneous walls such as the walls of old buildings.
Outras técnicas para tratamento da humidade são também inadequadas por um ou outro motivo. A electro-osmose é inadequada quando a resistência do terreno é elevada. A redução da secção absorvente tem implicações estruturais e arquitectónicas. A introdução de tubos de arejamento tem implicações estéticas e é pouco eficaz. A ocultação das anomalias por aplicação de revestimentos com porosidade e porometria controlada implica o aparecimento de efluorescências e não é aplicável em paredes não rebocadas. A ocultação das anomalias por colocação de uma forra interior separada por um espaço de ar diminui as áreas úteis, se não for possível ventilar pode não apresentar os
resultados esperados, não permite a visualização da parede original . Other techniques for treating moisture are also inappropriate for one reason or another. Electrosmosis is inadequate when the ground resistance is high. The reduction of the absorbent section has structural and architectural implications. The introduction of aeration pipes has aesthetic implications and is ineffective. Concealment of anomalies by application of porosity and controlled porometry coatings implies the appearance of effluorescence and is not applicable to untreated walls. The concealment of anomalies by placing an inner liner separated by an air space reduces the useful areas, if it is not possible to ventilate it may not have the Expected results, does not allow viewing of the original wall.
