Next, the operation of the above-configured ventilator will be described with reference to FIG.
And the drawing shown in FIG. In the total heat exchange rotor 4 used in the above-described ventilation device, when high-temperature air and low-temperature air flow in opposite directions in total heat exchange ventilation, heat gradients are generated between the upstream side and the downstream side of the rotor cross section, respectively.
The high-temperature region increases on the side where the high-temperature air flows (A side in FIG. 4A), and the low-temperature air flows on the side (B in FIG. 4A).
Side), the low-temperature region increases, and the rotation speed of the rotor 4 is sufficiently high, that is, several tens of revolutions / minute or more. Therefore, heat is sufficiently transferred, and the entire cross section does not reach the inflow air temperature. The temperature will be approximately the same as the incoming air temperature.

On the other hand, the outdoor air sucked from the outdoor air inlet 1b with the rotation of the blower fan 15 passes through the unheated heater 3 and reaches the total heat exchange rotor 4, where it passes as follows. Heat exchange with indoor air. When the season in use is summer, for example, the indoor air is lower in temperature and humidity than the outdoor air by air conditioning, and the total heat exchange rotor 4 is rotated at a speed of several tens of revolutions / minute. The indoor air is supplied to the air passage portion 4a of the total heat exchange rotor 4.
When the high-temperature and high-humidity outdoor air flows into the air passage portion 4b from opposite directions, the inflow side of the low-temperature and low-humidity air is set to the low-temperature and low-humidity, and the high-temperature A temperature / humidity gradient that causes high humidity occurs.

As a result, the high-temperature and high-humidity air flowing into the total heat exchange rotor 4 is deprived of heat and steam to the surroundings as the temperature and humidity of the surrounding rotor 4 gradually changes to low-temperature and low-humidity. It is becoming. Since the temperature and humidity near the rotor outlet are almost the same as the temperature and humidity of the low-temperature and low-humidity indoor air, the temperature and humidity of the air that has passed through the rotor 4 are as close as possible to the temperature and humidity of the indoor air. , Air holes 9

On the other hand, in dehumidification of indoor air, water vapor must be transferred from air having a low relative humidity to air having a high relative humidity. For this purpose, as shown in FIG. 5A, the high-humidity air is heated by a heater into 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 reduced to tens of tenths (actually about 10 rpm or less) during the total heat exchange, steam moves from the entire cross section of the rotor toward the ultra-low humidity air, and the rotor becomes Dry over the entire cross section. Then, the dried rotor moves to the inflow side of the low-humidity air, and takes water vapor from the low-humidity air. If the air from which the water vapor has been taken is returned to the room, the air is dehumidified. If the air to which the water vapor is added is returned to the room, the air is humidified. FIG. 5
(B) and (c) show the humidity distribution in the total heat exchange rotor during dehumidification and dehumidification. As can be seen from the figure, the change in humidity is large because the rotation speed is low. Here, if the rotational speed is set to several tens of revolutions per minute in the state of FIG. 5A, the change in the relative humidity in FIGS. 5B and 5C is the same as that in FIGS. 4B and 4C. 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 flows out in a state close to the temperature and humidity, and the movement of water vapor from low humidity air to high humidity air does not occur.

Next, the operation of the ventilating apparatus according to the above embodiment at the time of dehumidification will be described with reference to FIG. The indoor air sucked from the indoor air inlet 1a by the blower fan 15 passes through the unheated heater 2 and reaches the total heat exchange rotor 4, and the outdoor air sucked by the blower fan 16 from the outdoor air inlet 1b. The air is heated when passing through the heated heater 3 and reaches the total heat exchange rotor 4. When the season in use is, for example, the rainy season, both indoor air and outdoor air have high humidity, so it is necessary to move water vapor from indoor air to outdoor air to dehumidify indoor air. As a result, water vapor is transferred from the low humidity air to the high humidity air.

The high-humidity outdoor air becomes high-temperature ultra-low-humidity air when passing through the heated heater 3 and reaches the total heat exchange rotor 4. When passing through the air passage portion 4 b of the total heat exchange rotor 4, the total heat Steam is taken from the exchange rotor 4. Since the total heat exchanger rotor 4 is rotating at a slow enough rate that few tenths at full heat exchange, at the time the air passage portion 4b enters the chamber 1 1 and 1 2 from chamber 1 3 and 1 4 , air passage portion 4b of the chamber 1 1 and 1 in 2 has a whole super low humidity conditions. Thus, when the humid indoor air passes through the air passage portion (already ultra-low humidity) 4a of the total heat exchange rotor 4, the steam is deprived and the indoor air is dehumidified.

At this time, the rotation speed of the total heat exchange rotor 4 is several tens of minutes during the total heat exchange ventilation.
Although the amount of movement of water vapor between the air passing portions 4a and 4b is much smaller than that during the total heat exchange ventilation, the room air dehumidified as described above is the air opened by the opening 12b of the switching plate 12. The outdoor air that has been returned to the room through the blower fan 15 through the hole 10 dh and has become highly humid
Since the air is blown out of the room through the blower fan 16 through the air holes 9 dh opened by the air, the humidity of the room air decreases and the room can be dehumidified.

On the other hand, the operation in the case of humidification will be described with reference to FIG. 3. The flow of indoor air and the flow of outdoor air are the same as in the above-described dehumidification, but the indoor air is heated by the heater 2 and the outdoor air is heated. The difference is that it is not heated. When the season is winter, both indoor air and outdoor air have low humidity, and it is necessary to move the water vapor from the outdoor side to the indoor side. As a result, the water vapor moves from the low humidity air to the high humidity air. The indoor air is sucked from the indoor air inlet 1a and heated by the heater 2 to become high-temperature ultra-low-humidity air, reaches the total heat exchange rotor 4 and passes therethrough.
Steal more water vapor. Since the total heat exchange rotor 4 is rotating at a sufficiently low speed, the air passing portion 4a is
All the cross sections of the rotor 4 are in an ultra-low humidity state before moving to b.

As described in detail above, the present invention provides a total heat exchange ventilation by providing one total heat exchange rotor rotatable at a variable speed and a heating means for heating indoor air and outdoor air. Since the dehumidifying and humidifying functions are obtained, the structure can be greatly simplified as compared with the conventional two types of heat exchangers and those provided with a driving mechanism for driving the heat exchangers. This facilitates manufacture and can be provided at a low cost, and can be easily installed in a small space because the number of heat exchangers can be reduced to reduce the size.
