【発明の詳細な説明】
本発明は室内湿度の調節可能な空調換気扇に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioning ventilation fan capable of controlling indoor humidity.
空調換気扇は、周知のように、室内空気中の汚
染物質例えばCO2、CO、粉塵等を除去すると同
時に室内に吸入する室外空気を外部へ吐出される
室内空気と熱交換させて室内空気温度の著しい変
動を抑える省エネルギタイプである。 As is well known, an air conditioning ventilation fan removes pollutants such as CO 2 , CO, and dust from indoor air, and at the same time exchanges heat between outdoor air taken into the room and indoor air discharged outside to lower the indoor air temperature. It is an energy-saving type that suppresses significant fluctuations.
上記空調換気扇の熱交換タイプは主に２種類に
分類され、１つは室内空気と室外空気とを単に熱
交換させるのみのタイプ、他の１つは熱交換と同
時に湿度交換をも行なうタイプである。 The heat exchange type of the above-mentioned air conditioning ventilation fan is mainly classified into two types: one type is a type that simply exchanges heat between indoor air and outdoor air, and the other type is a type that exchanges humidity at the same time as heat exchange. be.
しかしながら、前者にあつては湿度交換が全く
行なわれないし、後者にあつても一定割合の湿度
交換が行なわれるだけで、その湿度交換量を調節
することができず、双方共充分な空調機能を有し
た換気扇とは言い難い。 However, in the former case, no humidity exchange is performed at all, and in the latter case, only a certain percentage of humidity exchange is performed, and the amount of humidity exchange cannot be adjusted, and both require sufficient air conditioning function. It is hard to say that it is a ventilation fan.

バイパス通路に室内湿度に応じて通路面積を調節
する手段を設ける構成とすることにより、上記従
来の不都合を解消するものである。 The present invention has been made in view of the above points, and includes a heat exchanger for an air conditioning ventilation fan that exchanges heat between indoor air discharged to the outside and outdoor air taken into the room. A moisture permeable part for humidity exchange connected in series to the heat exchange part is formed, and an outdoor air bypass passage is formed in parallel with the outdoor air passage of the moisture permeable part and is hygroscopically insulated from the indoor air passage. The above-mentioned conventional disadvantages are solved by providing the bypass passage with a means for adjusting the area of the passage according to the indoor humidity.
即ち、室内湿度が低い時はバイパス通路の通路
面積を小さくし、透湿部を通過する室外空気量を
増大して吸湿量を多量とする一方、室内湿度が高
い時はバイパス通路の通路面積を大きくし、透湿

量とする。これにより、熱交換部で室内空気と熱
交換した室外空気の湿度を室内湿度に応じて調節
できるから、従来に比して快適な室内環境が得ら
れる。 In other words, when the indoor humidity is low, the passage area of the bypass passage is reduced and the amount of outdoor air passing through the moisture permeable part is increased to increase the amount of moisture absorbed, while when the indoor humidity is high, the passage area of the bypass passage is reduced. The amount of moisture absorbed is reduced by increasing the amount of outdoor air passing through the moisture permeable part. As a result, the humidity of the outdoor air heat-exchanged with the indoor air in the heat exchange section can be adjusted according to the indoor humidity, so that a more comfortable indoor environment can be obtained than in the past.

直列に接続される。 An embodiment of the present invention will be described below based on the drawings. In the figure, an air conditioning ventilation fan 2 is attached to a wall 1 that separates an indoor room from an outdoor room. Inside the main body case 3 of this air-conditioning ventilation fan 2, there is a non-permeable heat exchanger 4 made of plastic or metal on the outdoor side, and a moisture-permeable heat exchanger 4 made of treated paper on the indoor side. A heat exchanger 5 which also performs heat exchange is provided, and these are connected in series at a joint 6.

成となつている。 The heat exchangers 4 and 5 have separate passages so that indoor air and outdoor air do not mix, and the indoor air passage 7 has an indoor air inlet 8 on the side of the main body case 3 on the indoor side. The indoor air outlet 9 faces the opening 10 on the outdoor side end surface of the main body case 3, while the outdoor air passage 11 has an outdoor air inlet 12 opened on the side of the main body case 3 on the outdoor side, and an outdoor air outlet 13.
is configured to face an opening 14 on the indoor side end surface of the main body case 3.

る。 Between the outdoor end opening 10 and the indoor air outlet 9 of the main body case 3 of the air conditioning ventilation fan 2, and between the indoor end opening 14 and the outdoor air outlet 13, a blower 15 for discharging indoor air is installed. A blower 16 for sucking outdoor air is provided, and each blower 15, 16
The operation is controlled by the control circuit 17 as appropriate depending on the concentration of pollutants such as CO 2 , CO, and dust in the indoor air.

An electric valve 19 is installed in the bypass passage 18, and the area of the passage is adjusted by a control circuit 20 based on the detected value of a humidity sensor (not shown) that detects indoor humidity. The ventilation resistance is selected to allow most of the flow.

る。 When indoor air pollutants reach a set concentration or higher,
The control circuit 17 starts operating the blowers 15 and 16, and the indoor air and outdoor air are exchanged.
There are two types of outdoor air flow for this exchange. One is sensible heat exchange with the indoor air flowing through the indoor air passage 7 in the heat exchanger 4, and the latent heat (sensible heat) is exchanged with the indoor air in the heat exchanger 5. (including heat) and humidity exchange at the same time, outdoor air outlet 13, blower 16, opening 14
The other flow is the flow that is discharged indoors through the outdoor air bypass passage 18, the electric valve 19, and the opening 14 after sensible heat exchange with the four heat exchangers. The outdoor air flow rate of each of these two flows is varied according to the indoor humidity. For example, as the indoor humidity becomes high, the control circuit 20 increases the opening degree of the electric valve 19, and the outdoor air flowing through the outdoor air bypass passage 18 increases. While the air flow rate increases, the outdoor air flow rate flowing through the outdoor air passage 7 in the heat exchanger 5 that performs humidity exchange decreases. As a result, the temperature of the indoor air discharged into the room from the opening 14 is adjusted by heat exchange with the indoor air, and the humidity is adjusted according to the indoor humidity, so that indoor contaminants are removed and comfortable. Air conditioning is provided.

側に位置させる構成である。 In the above embodiment, the heat exchanger 5 is used for both heat exchange and humidity exchange, but the heat exchanger 4
If the amount of heat exchanged is sufficient, it may be possible to exchange only humidity. In addition, the outdoor air bypass passage 18
Although the electric valve 19 whose opening degree changes according to the indoor humidity is provided as a mechanism for adjusting the passage area of the heat exchanger 4, an orifice or a diaphragm whose opening area changes according to the indoor humidity may also be used. The arrangement of No. 5 may be a reverse arrangement. Specifically, the heat exchanger 5 that performs both heat exchange and humidity exchange is located on the outdoor side, while the heat exchanger 4 that performs only heat exchange is located on the indoor side.

できる。 In addition, if a humidifier that humidifies according to the indoor humidity is provided in the main body case 3 on the downstream side of the outdoor air outlet 13 of the heat exchanger 5, the start-up performance of humidity control can be improved and the indoor drying time can be improved. humidification can be performed.
また、送風機１５，１６のオンオフ動作は汚染

構成としたが、手動により行なう構成でもよい。 Furthermore, although the configuration has been described in which the on/off operations of the blowers 15 and 16 are controlled by the control circuit 17 based on the contaminant concentration, the configuration may be such that the on/off operations are performed manually.

成される。 Furthermore, although the outdoor air bypass passage 18 is configured to be located outside the main body case 3, if the outdoor air bypass passage 18 is made of a non-moisture permeable material, it can be housed inside the main body case 3, and the aesthetic appearance can be improved. At the same time, heat exchange is also possible within the outdoor air bypass passage, achieving even greater energy savings than in the embodiments described above.
