SUMMARY OF THE INVENTION The object of the present invention is to provide a natural ventilation opening provided in an indoor zone where the temperature difference between indoor and outdoor is large, and a method for forcibly exhausting indoor air to the outside. An exhaust fan that constantly maintains air supply to the interior through the opening, and detects the degree of the temperature difference between the inside and outside, and reduces the opening degree of the natural ventilation opening when the temperature difference between the inside and outside is large, When the temperature difference between the inside and outside is small, the automatic opening degree control means for increasing the opening degree of the opening is provided, and the problem is solved by the indoor constant-ventilation system.

[0005] In this system, for example, when used in a highly airtight and highly insulated house that is heated in winter, it is possible to properly ventilate the room throughout the year without excess or shortage.

[0006] That is, in the winter, the indoor and outdoor temperature difference is considerably large in order to heat the indoor space. On the other hand, from the spring to the summer and the fall, although the cooling is performed in the summer, the temperature difference between the indoor and the outdoor is larger than that in the winter. Smaller.

[0007] Therefore, in the summer and the middle season when the temperature difference between the indoor and the outside is small, natural ventilation through the natural ventilation opening cannot be expected so much, and insufficient ventilation is likely to occur. The degree of opening of the natural ventilation opening is supplemented by large automatic control, and the interior is ventilated without shortage.

On the other hand, in winter, when the temperature difference between indoors and outdoors is large due to heating, natural ventilation can be performed due to the temperature difference between indoors and outdoors. However, since ventilation is also provided by an exhaust fan that compensates for insufficient ventilation in summer, ventilation is required. Excessive,
This over-ventilation is prevented by automatically controlling the degree of opening of the natural ventilation opening to be small, so that the room is ventilated without excess.

[0009] The constant ventilation system according to the present invention forms a proper ventilation state that is not too short or too long throughout the year. This ventilation system is provided with an exhaust fan and keeps the indoor and outdoor temperature difference while constantly operating. Is a simple system configuration that only controls the degree of opening of the natural ventilation opening by detecting the natural ventilation opening.It does not require ducts and can be performed easily and at low cost.It consumes little energy and is very economical. is there.

The automatic opening control means may detect the degree of the temperature difference between indoor and outdoor by detecting only the outside air temperature. There is a regularity in the change in indoor and outdoor temperature difference taking into account the use of heating in a highly airtight house.As mentioned above, the indoor and outdoor temperature difference increases in winter, and from spring to summer and autumn Tends to be smaller. Therefore, by detecting only the outside air temperature, there is no danger of malfunction even if the degree of the temperature difference between the inside and outside is detected. Accordingly, the detection mechanism for detecting the temperature can be simplified, and the system can be further simplified and the cost can be reduced. In particular, the use of non-electrical means as automatic opening control means contributes to energy saving. Needless to say, the detection of the degree of the temperature difference between the inside and outside may be performed by detecting the outside air temperature and the indoor temperature, and comparing the detected temperatures.

When the exhaust fan is installed in the indoor dirty zone and the natural ventilation opening is provided in the indoor fresh zone, it is possible to prevent the dirty zone from being fed into the fresh zone. At the same time, the air in the dirty zone can be efficiently exhausted to the outside by the exhaust fan. Not only that, since the exhaust fan is always running in relation to the system, the air in the dirty zone can be kept clean at all times. No switch operation is required.

The indoor space is divided into a plurality of spaces, the spaces to be ventilated are communicated with each other in a freely permeable manner, the exhaust fan is installed in a space corresponding to a dirty zone, and the opening for natural ventilation is installed. In addition to the fresh zone, a system configuration in which a fresh zone provided with an air supply fan for forcibly supplying outside air into the room may be provided. That is, some of the fresh zones do not have much indoor ventilation throughout the year. Rather, the seasons can even cause large gravity ventilation to the outside. Therefore, by providing an air supply fan in such a zone and performing ventilation in cooperation with the air supply fan and the exhaust fan, the zone can be sufficiently ventilated throughout the year. In other words, in the fresh zone, there is a place where ventilation can be performed without excess and deficiency with the opening adjustment type 3rd ventilation using the opening for natural ventilation, and a place where the 1st kind ventilation is required, and I recognized that Above, by configuring such a combined type ventilation system of the first type and the opening control type third type, it is possible to properly ventilate each room indoors throughout the year.
