Method and apparatus for drying rooms within a building

摘要

Drying apparatus (1, 1') for installation within a sealed damp or waterlogged room, the apparatus including sensing means (10, 12, 13) to sense the level of humidity within the room, heating means (3) to provide heat for the room, air circulation means (4, 6) for selectively circulating heated air within the room or selectively exhausting warm and humid air from the room and for allowing outside ambient air into the room, the apparatus also including sensor means (9, 10,11, 12, 13) for measuring selected characteristics indicative of water content within the room and means (6, 15) for cyclically changing the air within the room when a predetermined level of air humidity is reached, the apparatus being adapted to cyclically continue until the sensed humidity reaches a required level, the apparatus thereafter indicating, directly or indirectly, the completion of the drying process. A method of drying a room using such apparatus as also disclosed.
