[0016] Next In operation, now in order to a total heat exchange ventilation, in the position shown switching plate 7, 9, 14 in FIG. 1, the chamber 1 7 with the chamber 1 5 and chamber 1 8 and the chamber 1 6 When the operation is started in a state where the communication is established, the rotation of the blower fan 12 causes
Outdoor air sucked from the outdoor air inlet 1a passes through the opening 6a, a blower fan 12 in order to reach the chamber 1 1.
Here the flow is divided, a portion enters the chamber 1, 1a, the rest enters the chamber 1 1b. At this time, the heater 2 is not heated, and the divided air is supplied to the upper part 4 of the total heat exchange rotor 4.
After flowing into the chamber 1 3 passes through the a, it is the air supply from the indoor air discharge port 1d into the room.

On the other hand, at the time of total heat exchange ventilation, the switching plate 14 is folded, so that the air blown from the outlet 13 a of the blower fan 13 is directed to the outer periphery of the total heat exchange rotor 4. Thereby, the dynamic pressure of the blower fan 13 acts on the total heat exchange rotor 4 more strongly than the dynamic pressure of the blower fan 12,
The total heat exchange rotor 4 is rotated in the direction of the arrow in FIG. Then, since the rotation of the total heat exchange rotor 4 reaches a speed at which the difference between the total heat amounts of the indoor air and the outdoor air can be sufficiently conveyed, the total heat exchange is performed between the indoor air and the outdoor air, and the temperature and humidity of the outdoor air Is closer to the temperature and humidity of the indoor air, and the temperature and humidity of the indoor air are closer to the temperature and humidity of the outdoor air. FIG. 3 shows the positions of the switching plates 7 and 9 and the flow of air during total heat exchange ventilation.

Next, the switching plates 7, 9, and 14 are set to the positions shown in FIG. 2 in order to perform dehumidification, and the chambers 17 and 16 and the chambers 18 and 1 are moved to the positions shown in FIG.
When the operation is started in a state in which the blower fan 5 is connected, the blower fan 1
With the rotation of 3, the outdoor air sucked from the outdoor air intake 1a passes through the opening 6b and the blower fan 13 in order,
Reach the chamber 1 4. At this time, since the switching plate 14 is upright, the dynamic pressure from the blower fan 13 received by the total heat exchange rotor 4 and the dynamic pressure from the blower fan 12 become equal, and the total heat exchange rotor 4 does not rotate with the dynamic pressure. . The air reaches the chamber 1 4 bisected, partially enters the chamber 1 4a, the rest enters the chamber 1 4b.

On the other hand, with the rotation of the blower fan 12, the room air sucked from the room air inlet 1b is
a, it passes through the blower fan 12 in order to reach the chamber 1 1. Here the flow is divided, a portion enters the chamber 1 1a, the rest enters the chamber 1 1b. At this time, the heater 2 is not heated,
The bisected air is supplied to the upper part 4a of the total heat exchange rotor 4.
Passes through, this time with dehumidified in the total heat exchange rotor 4 becomes dry air, after flowing into the chamber 1 3, indoor air discharge port 1d
Is returned to the room from. Thus, the total heat exchange rotor 4
In the upper part 4a, the moisture is always taken away from the room air, and in the portion exposed to the room 14b , the moisture is always taken away by the outside air, and the balance around the bearing 5 is lost. Can be dehumidified. FIG. 4 shows the positions of the switching plates 7 and 9 and the flow of air during dehumidification.

The flow of indoor air and the flow of outdoor air during humidification are the same as during dehumidification, except that indoor air is heated by the heater 2 and outdoor air is not heated. That indoor air is sucked from the indoor air inlet 1b, part is heated by the heater 2, it deprives moisture from the total heat exchange rotor 4 passes through the portion exposed to the chamber 1 1b of the total heat exchange rotor 4, The remaining indoor air is the total heat exchange rotor 4
Passing through the portion exposed to the chamber 11a of the
After cooling, water is deprived, and both are returned to the room through the indoor air outlet 1d. Total heat exchange rotor 4 to become lighter dehumidified only portion exposed to the chamber 1 1b, rotates in the arrow direction in FIG.

On the other hand, the outdoor air is sucked from the outdoor air inlet 1a, passes through the lower portion 4b of the total heat exchange rotor 4 without being heated by the heater 3, and is deprived of moisture by the total heat exchange rotor 4, and The air is returned outside through the outside air exhaust port 1c. Thus, the lower portion 4b of the total heat exchange rotor 4, is always taken away moisture from the outdoor air, the exposed portion in the chamber 1 1b, part always moisture is absorbed by the indoor air, and exposed to the chamber 1 1a In this case, since moisture is always taken from the room air, the balance of the total heat exchange rotor 4 around the rotary bearing 5 is lost, and the total heat exchange rotor 4 continues to rotate. The humidification of the room air can be continuously performed as long as the amount of moisture taken by the room air at the portion exposed to the room 1b is larger than the amount of water taken from the room air at the portion exposed to the room 11a .
