<p>PURPOSE:To simultaneously heat and clean air, by a method wherein the air heated by a combustion device joins the air cleaned by passing through an electrically dust-collecting device, and the air mixed is blown through an air- outlet. CONSTITUTION:The outside air from an air-inlake 2 is turned into the air cleaned by passing through a filter 3, a dust-collecting electrode device 7 and a filter 8, and by a fan 5, the cleaned air is raised in a duct 6 and is led into a horizontal duct 12 and is spread into the internal part thereof. On the other hand, the air heated by a furnace 14 is raised by convection and is led into a duct 16 through an intake 17 and reaches a filter 19. After the heated air passes through this filter 19, harmful gases contained in the air are effectively removed, and the heated air is made clean. This clean, heated air is led into the horizontal duct 12 and joins the stream of the clean air sent by the fan 5, and they are made clean and warm, and the air clean and warm is exhausted from an air-outlet 13.</p> |
