A low pressure, low air volume system for heating and drying concrete walls in
a damp environment is disclosed. A wall unit consisting of a wall panel (10)
having a plurality of vertical grooves (14) and ridges (16) formed in a back
surface, the ridges in contact with a concrete wall surface and the grooves
forming a plurality of air channels in contact with the surface of the wall,
ducts heated air across the concrete surface of the wall, evaporating moisture
migrating through the wall. An upper and lower plenum (20) connect the air
channels of the wall unit with a remote system consisting of a dehumidifier
(50) and discharge pump (60), heating element (70) and fans (40) for moving
air through the system, the dehumidifier removing the moisture from the air
before recirculating it through the system.
L'invention concerne un système à basse pression et à faible volume d'air pour chauffer et sécher des murs en béton dans un environnement humide. Une unité formant un mur comprend une dalle (10) avec une pluralité de rainures (14) et de crêtes (16) verticales formées sur une surface arrière, les crêtes étant en contact avec une surface du mur en béton et les rainures formant une pluralité de conduits d'air en contact avec la surface du mur de façon à conduire de l'air chauffé sur la surface en béton du mur et à provoquer l'évaporation de l'humidité qui traverse le mur. Des chambres supérieure et inférieure (20) relient les conduits d'air de l'unité formant le mur à un système éloigné qui comprend un déshumidificateur (50) et une pompe de décharge (60), un élément de chauffage (70) et des ventilateurs (40) pour faire circuler de l'air à travers le système, le déshumidificateur éliminant l'humidité de l'air avant qu'il ne soit remis en circulation à travers le système.
