る。By the way, in Japanese weather, when the outdoor temperature is low as in the winter and the risk of condensation is high (condensation risk period), the absolute humidity is low and is 7 g / m 3 or less, and the outdoor temperature is as in the summer. When the humidity is high and dew does not easily occur (condensation safety period), the absolute humidity is high and is 10 g / m 3 or more. Therefore, in the winter when the absolute humidity is low, there is a high risk of dew condensation.Therefore, the detection level is lowered to prevent the occurrence of dew condensation so that automatic operation can be performed quickly with a small amount of water vapor, and the high absolute humidity In summer, the risk of condensation is low, so
It is possible to reduce the energy loss due to useless ventilation by raising the detection level so that automatic operation is not performed when a small amount of steam is generated. At this time, if the absolute humidity is, for example, 9 g / m 3 or more and it is determined that no dew condensation will occur, the detection level can be set to the upper limit and the automatic ventilation can be stopped to further reduce the energy loss. .

FIG. 3 (f)). Further, the air volume of constant ventilation, that is, the air volume of the base ventilation can be linearly changed according to the risk of dew condensation (FIGS. 2 (g) and 3 (g)). Thus, in this embodiment, the absolute humidity of the outdoors is monitored for 24 hours,
The risk of dew condensation is determined by the minimum absolute humidity during 24 hours, and the indoor water vapor generation amount is calculated from the indoor temperature and humidity measured by the temperature sensor 2 and the relative humidity sensor 1 installed indoors. , Provide automatic ventilation according to the risk of condensation. Thereby, the required minimum ventilation amount can be always secured by the ventilation means 9.
