The angle of the damper may be gradually changed. As in the present invention, by using a rotary damper driven by a motor, the angle of the damper is automatically changed based on at least one of a change in temperature on the inlet side and a change on the outlet side of the ventilation passage. ,
The ventilation amount of the ventilation passage can be easily adjusted according to the temperature.

The regenerative electric heating device 67 operates as follows. First, the electric heater 71 is caused to generate heat using electric power at midnight with the heating device side dampers 83 and 85 closed, and the heat storage body 73 is stored to a predetermined temperature (700 ° C.). When using the heating, the heating device side dampers 83 and 85 are opened and the fan device 77 is operated. Thus, the air sucked from the intake port 81a by the fan device 77 is heated through the air heating passages 81 and discharged from the air supply port 67a.
The temperature adjustment is performed by changing the opening / closing degree of the heating device side dampers 83 and 85 to adjust the discharge amount of the hot air. When the warm air is exhausted from the air supply port 67a, the warm air is blown out along the bottom surface 43a of the underfloor space 43 to heat the underfloor space 43 as shown in FIG.

When the temperature of the first-floor room 63 is higher than the predetermined temperature, the damper 7 is connected to the ventilation passage 11e.
Is closed, the hot air from the underfloor space 43 to the first-floor room 63 is shut off, and the heat storage type electric heating device 67 is efficiently stored heat. The temperature of the regenerative electric heating device becomes extremely high, so it is difficult to adjust the temperature in the first-floor room 63. However, if such a ventilation adjusting device 1 is used, the adjustment of the ventilation amount of the ventilation passage 11e becomes extremely simple. Further, in such a regenerative electric heating device 67, the amount of heat released from the regenerative electric heating device 67 is adjusted by the heating device side dampers 83 and 85 to adjust the room temperature. Heating device side damper unit 8
With only 3,85, the room temperature cannot be sufficiently adjusted. Therefore, by providing the ventilation adjusting device 1, it is possible to more reliably adjust the room temperature.
