In a device (11) for supplying a building interior (3), which is connected to the atmosphere via a supply-air duct (12) for introducing fresh air and via an exhaust-air duct (13) for removing the stale air, a fan (14, 16) cooperating with a common heat exchanger (20) being inserted in each of the ducts (12, 13) and the supply-air duct (12) being guided, in the end region, via a heating or cooling element (10), the exhaust-air duct (13) is provided with a branch pipe (31) for circulating the warm air (19), by means of which branch pipe the exhaust-air duct (13) can be optionally connected to the supply-air duct (12). As a result of this arrangement, it is possible to provide a circulating-air circuit, by means of which the building interior (3) can be heated or cooled independently of the atmosphere. The temperature level of the room (3) can thus be individually adjusted without difficulty and without great structural expense. <IMAGE> |
