Abstract
A flow passage through which a heat exchange medium flows is formed at least at a part of each airflow ductto, and the heat exchange medium flowing through the passage (t) is allowed to cool or heat air flowing through the airflow ductto. Alternatively, a heat generation film H is formed at a part of an inner surface of an air passage of each airflow ducttoand is allowed to heat air flowing through the airflow ductto. Because the airflow ductstoper se are first cooled or heated by the heat exchange medium flowing through the passage (t), the heat exchange loss with the airflow ducts, that has occurred in the prior art, can be eliminated. Because air conditioning wind is cooled or heated inside the airflow ductsto, too, instantaneous cooling/warming performance can be improved.
