<p>A heating apparatus provided with a central duct (3) extending to the side of the driver's seat through a front-to-rear changeover damper (2) connected to the air conditioning unit (1), a rear duct (4) extending to the rear side of the driver's seat through the front-to-rear changeover damper, and outlets (9) formed at tips of the branched parts of said rear duct for the purpose of obtaining an optimum temperature distribution in a cabin even under environmental conditions in winter. The apparatus is further provided with a lower outlet (6) for supplying air along the floor through an above-to-below changeover damper (5) connected to the tip of the central duct, a front duct (7) rising through the above-to-below changeover damper, and a front outlet (8) provided at the tip of said front duct. An optimum ratio of air flow distribution is set with the use of these changeover dampers (2, 5).</p> |
