In the conventional dry dehumidifying / humidifying device as described above, the entire device is installed indoors, and only the outdoor air supply port 105 and the outdoor air exhaust port 106 penetrate the wall. Therefore, when the outdoor air is supplied or exhausted, the flow path is meandering and the cross section of the flow path is small. For this reason, the pressure loss resistance of the flow path becomes large, so that the amount of air blown by the blower cannot be made large, so that there are drawbacks that the adsorption performance of the adsorbent 101 in particular decreases and the noise of the blower becomes large.

Further, since the conventional dry dehumidifying / humidifying device has a structure in which the device main body is installed in the room, there is a problem that the device main body projects into the room, impairing the indoor action and aesthetics.

Therefore, according to the present invention, the pressure loss resistance of the flow passage can be reduced to increase the amount of air blown by the blower to increase the adsorption performance of the adsorption / dehumidification element and reduce the noise of the blower. Another object of the present invention is to provide a ventilator capable of reducing the protrusions in the room so as not to disturb the indoor activities or impair the aesthetics.

The heater 2 is energized. The outdoor air is sucked from the outdoor air supply port 5 and heated by the heater 2 to become high temperature air. The high temperature air heats the adsorption / dehumidification element 1, releases the moisture adsorbed in the adsorption process described above, and is exhausted from the indoor exhaust port 8 to supply humidified air into the room. The humidification process in this case is a humidification action involving ventilation. Hereafter, humidify and ventilate the room while repeating regeneration and adsorption.

The other dehumidifying / humidifying functions have similar functions. Next, the case of exhaust ventilation of ventilation function No. 7 will be described. The air supply switching damper 9 closes the outdoor side. The exhaust switching damper 10 closes the indoor side. The heater 2 is not energized. When the blower 3 is operated, the dirty air in the room is
Exhausted to the outside. That is, it becomes the function of exhaust ventilation.

The exhaust switching damper 10 closes the outdoor side. The heater 2 is not energized. When the blower 3 is operated, the outdoor clean air is exhausted (supplied) indoors. That is, it becomes the action of supply air ventilation. At this time, if the outside air is cold and the supply air feels cold and cold, turn on the heater 2
It becomes the supply air preheat ventilation which is 9, and prevents cold air from entering.

Next, the heating function No. 10 will be described. The air supply switching damper 9 closes the outdoor side. The exhaust switching damper 10 also closes the outdoor side. The heater 2 is energized. When the blower 3 is operated, the room air is sucked from the room air supply port 7, heated by the heater 2, and has a function of supplying warm air to the room from the room exhaust port 8 to heat the room. In addition,
Needless to say, in order to reduce the heat radiation loss from the heater 2, the heater 2 having a low surface temperature and the heat insulating material 13 having good heat insulating performance are used.

In the above embodiment, as shown in FIG.
