本発明は、全熱交換素子を用いて室内の状態を
快適に保ちつつ、室内の汚れた空気を換気する装
置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device that uses a total heat exchange element to ventilate indoor dirty air while maintaining a comfortable indoor condition.

通路を形成している。 A conventional rotary total heat exchange element has a configuration as shown in FIG. In FIG. 1, reference numeral 1 denotes a total heat exchange element rotatably installed within a case 2, and is connected to a motor 3 by a shaft 4.
A part of the case 2 is separated by a partition plate 5, and impellers 7 and 8 are provided on both sides of the partition plate 5. Impellers 7, 8 are coupled to motor 6. A louver 9 constitutes one surface of the case 2, and has an opening in a portion thereof. A shutter 10 is formed on the opposite surface of the louver 9, and forms a wind passage with an opening provided in the louver 9.

When rotated simultaneously, impellers 7 and 8 direct air in the directions of arrows A and B in FIG. 1, respectively. Therefore, the air is supplied to the louver side, that is, into the room, and is exhausted at the same time, and both of them pass through the total heat exchange element 1. At this time, the supplied air obtains sensible heat and latent heat from the exhausted air via the total heat exchange element 1 and is supplied into the room. As a result, the supplied air is only ventilated at a temperature and humidity close to that of the air entering the room.
しかしながら、室内の状態が室外に比べて悪い
場合、すなわち地下室や梅雨時の室内など、室内
の方が湿度が高い場合などにおいては、上記装置
では除湿できず不都合であつた。 However, when indoor conditions are worse than outdoors, such as when humidity is higher indoors, such as in a basement or indoors during the rainy season, the above-mentioned device cannot dehumidify, which is inconvenient.
本発明は上記従来技術に鑑み、通常の換気扇を
設置することなく、冷暖房時および通常時におけ

Since the only difference from the conventional example shown in the figure is the total heat exchange element section, a description of the common parts will be omitted. 11 to 20 in Figure 2 are 1 to 1 in Figure 1
Each corresponds to 0. However, 14 and 14' are shafts, and 11 and 11' are total heat exchange elements and sensible heat exchange elements. The sensible heat exchange element is made of metal or resin, and mainly exchanges sensible heat. A total heat exchange element is a base material such as paper, cloth, ceramic, or resin coated with or impregnated with moisture absorbing agents such as lithium chloride, silica, and alumina, and is used to exchange total heat (sensible heat and latent heat). .

ぼさない効果が生じる。 Next, the operation will be explained. FIG. 3 shows an example during cooling in summer. High-temperature, high-humidity air outside the room on the right side of FIG. 3 is taken in by the fan 17 shown in FIG. 2, and only sensible heat is exchanged by the sensible heat exchange element 11', resulting in air with high relative humidity. Furthermore, this air absorbs moisture in the total heat exchange element 11, and air at a lower temperature and lower humidity than outside is supplied into the room. Further, the low temperature, low humidity air in the cooled room receives moisture in the total heat exchange element 11 due to the difference in relative humidity, and becomes low temperature, high humidity air. Furthermore, this air receives sensible heat in the sensible heat exchange element 11',
Exhausts air that is hotter and more humid than indoors to the outside.
Rotating both heat exchange elements 11 and 11' at the same time as shown in Figure 3 is the same as rotating the total heat exchange element, but in this device, the temperature of the outdoor air is lowered once and the relative humidity is increased. Since the temperature is increased, moisture absorption of the second stage total heat exchange element 11 is improved. Furthermore, even if dew condensation occurs, it will only condense on the sensible heat exchange element 11'.
This produces the effect that the moisture absorbent contained in the latent heat exchange element 11 is not adversely affected.
第４図は梅雨時の運転例で、この場合第４図左

にすれば湿気は全熱交換素子１１に蓄えられるだ
けで、顕熱のみ交換するため、除湿と換気ができ
る。また梅雨時だけでなく、地下室や地下街など
の湿気の多い場所における換気にも有利となる。 FIG. 4 shows an example of operation during the rainy season. In this case, the indoor side on the left side of FIG. 4 has higher humidity than the outdoor side, and it is disadvantageous to rotate the sensible heat exchange element 11' and the total heat exchange element 11 at the same time. In this case, it is necessary to dehumidify and ventilate the room, so the rotation of all the heat exchange elements is stopped and only the sensible heat exchange element 11' is rotated. In this way, moisture is only stored in the total heat exchange element 11 and only sensible heat is exchanged, so that dehumidification and ventilation can be performed. It is also advantageous not only during the rainy season, but also for ventilation in humid places such as basements and underground malls.
第５図は室内および室外の温度、湿度の差があ
まりなく、ただ単に換気する場合を示す。この場
合両方の熱交換素子の回転を止めフアンのみを動
かす。第５図右側が室外側である。 Figure 5 shows a case where there is not much difference in temperature and humidity between indoors and outdoors, and ventilation is simply performed. In this case, the rotation of both heat exchange elements is stopped and only the fan is moved. The right side of Figure 5 is the outdoor side.
このように本発明によれば、室内と室外の温度
