Total heat exchange with indoor air. When the season in use is, for example, summer, the indoor air has a lower temperature and lower humidity than the outdoor air due to air conditioning, and the total heat exchange rotor 4 is rotated at a speed of several tens revolutions / minute, so that the low temperature and low humidity is maintained. The indoor air is the air passage portion 4a of the total heat exchange rotor 4.
Then, when the high-temperature and high-humidity outdoor air flows into the air passage portion 4b from the directions opposite to each other, the low-temperature low-humidity air inflow side and the high-temperature high-humidity air inflow side increase in temperature in the entire cross section of the total heat exchange rotor 4. A high humidity temperature-humidity gradient occurs.

It will become. Since the temperature and humidity near the rotor outlet are almost the same as the temperature and humidity of low-temperature low-humidity indoor air, the temperature and humidity of the air passing through the rotor 4 are as close as possible to the temperature and humidity of the indoor air, and the air passage 7 and the opening 12a. , Air vent 9 er
After reaching the blower fan 15, the air is discharged from the indoor discharge port 1c. That is, as described with reference to FIG. 4, the inflowing high-temperature and high-humidity air approaches the temperature and humidity of the inflowing low-temperature and low-humidity air as much as possible, so that the total heat exchange efficiency is approximately 80-

Therefore, as shown in (a) of FIG. 5, high-humidity air is heated by a heater to form high-temperature ultra-low-humidity air, which is sent to the total heat exchange rotor. At this time, if the rotation speed of the total heat exchange rotor is slowed down to 1/10 (actually about 10 rpm or less) during total heat exchange, water vapor moves from the entire rotor cross section toward the ultra-low humidity air, and Dry over the entire cross section. Then, the dried rotor moves to the inflow side of the low-humidity air and deprives the low-humidity air of water vapor. If the air deprived of water vapor is returned to the room, it is dehumidified, and if the air added with water vapor is returned to the room, it is humidified. Note that FIG.
(B) and (c) of Figure 3 show the humidity distribution in the total heat exchange rotor during dehumidification and humidification. As can be seen from the figure, the change in humidity is large because the rotation speed is slow. Here, if the rotation speed is set to several tens of revolutions / minute in the state of FIG. 5 (a), the changes in the relative humidity in FIGS. 5 (b) and 5 (c) are similar to those in the shapes of FIGS. 4 (b) and 4 (c). become,
Heat exchange is performed between high temperature ultra low humidity air and low humidity air, and low humidity air is high temperature ultra low humidity air (absolute humidity is the same as high humidity air).
It comes out in a state close to the temperature and humidity of, and the movement of water vapor from the low humidity air to the high humidity air does not occur.

とになる。Next, the operation of the ventilation apparatus according to the above-described embodiment during dehumidification will be described with reference to FIG. The indoor air sucked from the indoor air intake 1a by the blower fan 15 passes through the unheated heater 2 to reach the total heat exchange rotor 4, and the outdoor air sucked from the outdoor air intake 1b by the blower fan 16 is supplied. The air is heated as it passes through the heated heater 3, and reaches the total heat exchange rotor 4. When the season used is, for example, the rainy season, both indoor air and outdoor air have high humidity, so it is necessary to move water vapor from the indoor air to the outdoor air to dehumidify the indoor air. As a result, water vapor will be transferred from the low humidity air to the high humidity air.

Since the total heat exchange rotor 4 is rotating at a sufficiently slow speed of several tenths during total heat exchange, when the air passage portion 4b enters the chambers 1 3 and 1 4 from the chambers 1 1 and 1 2. The air passage portions 4b in the chambers 1 1 and 1 2 are in the ultra-low humidity state throughout. As a result, when the high-humidity indoor air passes through the air passage portion (which has already become ultra-low humidity) 4a of the total heat exchange rotor 4, water vapor is deprived and the indoor air is dehumidified.

The amount of movement of water vapor between the air passage portions 4a and 4b is much smaller than that during total heat exchange ventilation, but the room air dehumidified as described above is the air opened by the opening 12b of the switching plate 12. The high-humidity outdoor air returned to the room through the blower fan 15 from the hole 10 dh is discharged to the outside through the blower fan 16 from the air hole 9 dh opened by the opening 12a. Humidity is lowered and it becomes possible to dehumidify the room.

となっている。On the other hand, the operation in the case of humidifying will be described with reference to FIG. 3. The flow of the indoor air and the flow of the outdoor air are the same as those in the above dehumidification, but the indoor air is heated by the heater 2 and the outdoor air is The difference is that it is not heated. When the current season is winter, both indoor air and outdoor air have low humidity, and it is necessary to move the steam from the outdoor side to the indoor side, and as a result, the steam is moved from the low-humid air to the high-humid air. The indoor air is taken in through the indoor air intake 1a and heated by the heater 2 to become high-temperature ultra-low humidity air which reaches the total heat exchange rotor 4 and, when passing through it, the total heat exchange rotor 4
Take more water vapor. Since the total heat exchange rotor 4 is rotating at a sufficiently slow speed, the air passage portion 4a becomes the air passage portion 4a.
By the time it moves to b, the entire cross section of the rotor 4 is in an ultra-low humidity state.

Water vapor is deprived of. Then, the room air humidified when passing through the air passage portion 4a of the total heat exchange rotor 4 is returned to the room through the blower fan 15 from the air hole 10 dh opened by the opening 12b of the switching plate 12, outdoor air steam was deprived when passing through the air passage portion 4b of the total heat exchange rotor 4 is the return air to the outside through the air hole 9 dh than the blower fan 16 which is opened by the opening 12a of the switching plate 12 It
