として使用し冷暖房効果を向上させることにある。[Detailed Description of the Invention] The present invention relates to an air conditioning ventilation fan, and its purpose is to:
The heat exchange element can be moved at predetermined time intervals to improve heat exchange efficiency and durability of the heat exchange element, and when there is no air conditioning or heating, forced simultaneous supply and exhaust is performed without heat exchange to provide ventilation. The aim is to increase the amount of air and use it as a circulator during heating and cooling to improve the effectiveness of heating and cooling.

紙を透過して交換していたので熱交換率は十分高いとは
言えず、また排気及び給気中の塵埃が紙の表面に付着し
熱伝導率及び湿度、交換率を低下させていた。Conventionally, as shown in FIG. 1, in an air conditioning ventilation fan, a heat exchange element 101 is fixed at the intersection of an exhaust ventilation path and an air supply ventilation path, and the exhaust blades 102 and the air supply blades 103 are rotated multiple times by a motor 104. Heat exchange was performed by a heat exchange element 101. The heat exchanger plate of the heat exchange element 101 is generally made of moisture permeable paper or the like, but paper originally has a low thermal conductivity, and humidity is exchanged by passing through the paper, so the heat exchange rate is low. The temperature was not high enough, and dust in the exhaust air and air supply adhered to the surface of the paper, reducing thermal conductivity, humidity, and exchange rate.

るので好しくなかった。For this reason, a filter 106 was installed at the exhaust air and air supply inlets of the heat exchange element 101 to remove dust, but minute particles passed through the filter 105, resulting in the aforementioned reduction in heat exchange efficiency. This is not preferable because the filter 106 itself becomes a resistance.

、スペース等の点で無理があった。The air conditioning ventilation fan performs its function during cooling and heating, but in the intermediate seasons of spring and autumn, even though there is no need for heat exchange, exhaust air and supply air pass through the heat exchange element 101. Air volume cannot be used effectively, and conventional air conditioning ventilation fans can only perform total heat exchange ventilation or only sensible heat exchange ventilation.For example, in basements, total heat exchange ventilation is usually sufficient, but in the summer the humidity is high. Although it is necessary to carry out sensible heat exchange ventilation, it has the disadvantage of not being able to do so. In addition, when heating and cooling, there is a considerable temperature difference between the ceiling and the floor, so it is desirable to install a circulator, but it is not possible due to cost, space, etc. to install an air conditioner, an air conditioning ventilation fan, and a circulator in the same room.

B...
...>B', sensible heat is taken away from the outside air supplied into the room, and moisture is desorbed from the moisture absorbing material of the heat transfer plate 11 and the spacer plate 12, becoming high temperature and high humidity and being exhausted to the outside. in this case,
Desorption heat (negative due to endothermic reaction) is generated and heat is exchanged with the outside air to lower the temperature of the high temperature indoor air, but this heat is supplied to the air through the heat transfer plate 11. Sensible heat is taken from the outside air and used effectively.

Sensible heat is imparted to the indoor air exhausted outdoors along the line, and moisture is adsorbed by the moisture absorbing material of the heat transfer plate 11 and the spacer plate 12, and the air is supplied indoors at a low temperature and low humidity. In this case, adsorption heat is generated and heat is exchanged with the indoor air, raising the temperature of the low-temperature outside air.However, this adverse effect is caused by the transfer of sensible heat to the exhausted indoor air via the heat transfer plate 11. It is resolved by giving.

ことになり、有効に利用される。Next, when the adsorption and desorption of moisture in the moisture absorbing material of the heat transfer plate 11 and the spacer plate 12 reaches near saturation, the heat exchange element 8 is rotated 9o0 by the motor 10 around the rotating shaft 9 and held. Outside air does not pass through the 80 layers of heat exchange elements through which indoor air passed before rotation, and the outside air passes through the heat exchanger plates 11 and spacing plates 12 of this layer, which are low temperature and low humidity due to indoor air. Sensible heat is taken away, moisture is adsorbed, and the air is supplied indoors at a lower temperature and humidity than the outside air. Then, the sensible heat is stored in the heat exchanger plate 11 and the spacer plate 12, becomes saturated, and is taken away via the heat exchanger plate 11 by the indoor air exhausted to the outside. In addition, heat of moisture adsorption is generated, which is applied to the exhausted indoor air via the heat exchanger plate 11 as described above. On the other hand, indoor air is now passing through the layer of the heat exchange element 8 that the outside air was passing through, and the indoor air is passing from the heat transfer plate 11 and the spacing plate 12 of this layer, which has become high temperature and high humidity due to the outside air. Sensible heat is given to the air, moisture is desorbed,
Indoor air becomes hot and humid and is discharged outdoors. Then, the sensible heat stored in the heat exchanger plate 11 and the spacer plate 12 will be radiated soon, and the sensible heat will be taken away from the outside air supplied into the room via the heat exchanger plate 11. In addition, heat of desorption of water (negative due to endothermic reaction) is generated, but this is effectively used as sensible heat is taken away from the supplied outside air via the heat exchanger plate 11 as described above. .

うに透湿性を有する伝熱板を介して顕熱と水分の交換を
行なうのに比べ全熱交換率が相当向上する。なお、暖房
時においても同様の作用で全熱交換率が向上する。This operation is repeated to perform total heat exchange ventilation between indoor air and outdoor air. Sensible heat can be exchanged not only through the heat exchanger plate 11, but also through heat storage and heat radiation. The exchange is carried out by adsorption and desorption between the moisture absorbing material of the heat transfer plate 11 and the spacing plate 12, and the heat of adsorption and desorption can also be used effectively through the heat transfer plate 11, eliminating the harmful effect of the heat transfer. The total heat exchange rate is considerably improved compared to exchanging sensible heat and moisture through a humid heat exchanger plate. Note that during heating, the total heat exchange rate is improved by the same effect.

生じる。In addition, even if dust adheres to the end face of the heat exchange element 8, which was the inlet at some point in the exhaust ventilation path and the supply air ventilation path,
The rotation of the heat exchange element 8 acts as an outlet and blows off dust, and the direction of the air on the heat exchange plate 11 is reversed by rotating the heat exchange element 8 on the heat exchange plate 11. This eliminates the accumulation of dust, which prevents the air volume and heat exchange rate from decreasing due to dust clogging the end face of the heat exchange element 8 and the heat exchanger plate, and eliminates the need for filters and cleaning. The advantage is that you don't have to do much.
