  The ventilation device is installed on the wall surface of the house, and in order to constantly ventilate the house, with the damper 20 as the switching means closed, the inner peripheral air passage 8 in the wind tunnel 3 is used to The exhaust motor 7 is operated to exhaust indoor air from the exhaust port 18 on the indoor side, and exhaust harmful indoor substances (formaldehyde as an example) to the outside of the room to maintain the health of the residents. Is.

  Further, the air supply impeller 4 and the air supply drive motor 6 are operated using the outer peripheral air passage 12, and the outdoor air is supplied from the constant air supply port 15 on the indoor side. This balances the air volume between the supply air and the exhaust air so as not to cause a difference in static pressure between the room and the room to prevent inadequate ventilation due to the airtight situation of the room.

  In order to cool the room by introducing cool air from the outside at night in the summer, the damper 20 as the switching means is opened and the direction is directed so as to blow out the air current in the center of the room. The wall is not polluted, energy is saved, and temporary air is supplied via the simple filter 19 in the temporary air inlet 16.

  When performing the temporary air supply, the air supplied through the outer air passage 12 passes, that is, the supplied air uses the outer air passage 12, but the outer air passage 12 is compared with the inner air passage 8. Since the cross-sectional area is large, the rotational speed of the air supply impeller 4 and the air supply drive motor 6 can be improved, and the amount of air passing through the outer peripheral air passage 12 can be increased.

  Even if the exhaust impeller 5 and the exhaust drive motor 7 are not attached and only the air supply is performed, the ventilation is always satisfied. However, the exhaust impeller 5 and the exhaust drive motor 7 are attached at the same time to supply the air. Because exhaust does not depend on the airtightness of the house, stable ventilation is possible.

  Here, when the outdoor temperature becomes lower than the indoor temperature, it becomes possible to perform outdoor air cooling. For example, when the difference between the outdoor temperature and the indoor temperature has a reference temperature difference (for example, indoor temperature−outdoor temperature = 2K). Since the conditions for the outside air cooling are set, the rotational speed of the air supply impeller 4 and the air supply drive motor 6 can be improved, and the extra charge can be increased to sufficiently obtain the effect of the outside air cooling.

  When the rotational speed of the air supply impeller 4 and the air supply driving motor 6 is improved to increase the amount of air passing through the outer peripheral air passage 12, the exhaust impeller 5 and the exhaust driving motor 7 have the rotational speeds increased. Therefore, when the static pressure of the inner peripheral air passage 8 and the static pressure of the outer peripheral air passage 12 are unbalanced, and the amount of change in the rotational speed of the air supply impeller 4 and the air supply drive motor 6 is large (example) When the temporary air supply is 120 m3 / h with respect to the constant air supply 30 m3 / h), the air is short-circuited from the gap between the inner peripheral air passage 8 and the outer peripheral air passage 12, and the exhaust impeller 5 and the exhaust driving motor 7 The effective ventilation may be reduced if you are operating. In such a case, the exhaust impeller 5 and the exhaust drive motor 7 are stopped, so that an air short circuit can be prevented, the effective ventilation amount can be increased relatively, and energy saving operation can be performed. .

  Further, when the exhaust impeller 5 and the exhaust drive motor 7 are driven, a sound is generated. However, in the constant supply with the damper 20 closed, the sound level is low due to the effect of the damper 20 being closed, but the damper 20 In the case of temporary supply air that opens, the sound generated by the exhaust impeller 5 and the exhaust drive motor 7 may leak from the temporary supply port 16. Therefore, generation of sound can be suppressed by stopping the exhaust impeller 5 and the exhaust drive motor 7.
