<p>PURPOSE:To heat lower floors of a building effectively by circulating the hot air at an upper floor forcibly to the lower floor. CONSTITUTION:An air circulating passage 2 is formed in the manner that it extends from the upper floor of a building 1 to a lower floor, and a fan 3 is provided at a proper part of the passage 2 for circulating the hot air at the upper floor to the lower floor. By applying the above arrangement in a small multistoried building such as one called ''pencil building'', the hot air collected at the upper floor can be circulated forcibly to the lower floor, so that the efficiency of heating the lower floors can be raised. Thus, it is enabled to achieve efficient space heating of a building.</p> |
