PURPOSE:To reduce lowering of the heating temperature of blowoff air on the indoor side owing to a heat loss to a foot warmer body during heating by providing a heating means for blowoff air and a blowoff temperature control means to control the blowoff temperature of air-conditioned air. CONSTITUTION:During heating, the temperature of an electric heater 15 wound around the inside and the outside of a heating device 2 is changed based on a blowoff temperature set at a blowoff temperature control device 3. Heat generated by the electric heater 15 is radiated by a radiating part 16 wherein radiation discs formed of a material, such as aluminum, having excellent thermal conductivity, are concentrically arranged. This constitution adjusts a blowoff temperature through effective control of a heating temperature and sets a blowoff temperature of airconditioned air at each floor blowoff unit not by a quantity of heat absorbed by a foot warmer body when air-conditioned air passes an underfloor space, and uniformizes indoor temperature distribution. Further, a blowoff air cooling means is provided instead of a blowoff air heating means. Further, a sound absorbing means formed of a sound absorbing material is provided. |
