However, in the above conventional example, since the ventilation system is configured to exhaust the air in the target area by simply comparing the measured humidity and the reference humidity, there is a humidity difference obtained by subtracting the outside air humidity from the humidity in the target area. When the humidity is higher than a preset reference humidity, high-humidity underfloor air is discharged to the outside. Although this is not a problem in itself, there is a problem that when the humidity is lower than a preset reference humidity, the humidity under the floor is increased by the outside air. If such a problem is left as it is, there is a problem that the stagnation air in the target area stays in a hot and humid state for a long time without performing the ventilation operation, and the equipment in the target area is damaged. These problems have also occurred in indoor ventilation systems that ventilate air within the indoor target area.

The present invention has been made in view of such problems of the conventional example, and an object of the present invention is to provide a wireless ventilation unit and a ventilation system that can appropriately control the humidity in the target area.

The present invention that solves the above-described problems is characterized in that in the ventilation system, the operation of the ventilation unit is remotely controlled by radio, and the air flow is generated by switching between supply air and exhaust air at regular intervals. Similarly, according to the present invention, in a ventilation system including a ventilation unit and a centralized controller unit that remotely controls the operation of the ventilation unit by radio, the air flow is generated by switching between supply air and exhaust air at regular intervals. The ventilation fan is controlled by a centralized controller unit.

Similarly, the present invention relates to a ventilation system comprising a ventilation unit and a centralized controller unit that remotely controls the operation of the ventilation unit wirelessly. The ventilation unit is composed of an indoor hood, a dustproof filter, a ventilation fan, a heat storage element, a sleeve, and an outdoor hood, and is attached to the ventilation unit. The length of the sleeve is adjusted according to the thickness of the outer wall.

Similarly, the present invention that solves the above-described problems is a ventilation system that includes a ventilation unit and a centralized controller unit that remotely controls the operation of the ventilation unit wirelessly. The ventilation unit is controlled from the indoor hood, the dust filter, the ventilation fan, the heat storage element, the sleeve, and the outdoor hood. The length of the sleeve is adjusted in accordance with the thickness of the outer wall to which the ventilation unit is attached, and one or more ventilation units are provided.

Similarly, the present invention that solves the above-described problems is a ventilation system that includes a ventilation unit and a centralized controller unit that remotely controls the operation of the ventilation unit wirelessly. The ventilation unit is controlled by the centralized controller unit so as to switch the air and exhaust and cause the air flow.

According to the present invention, the operation in the ventilation mode can be performed when the internal humidity is higher than the outside air humidity, and the operation in the stagnation prevention mode can be performed when the internal humidity is low. For this reason, it is possible to perform optimal control such as reducing the humidity in the target area without taking in high-humidity outside air or stopping the operation.

Further, according to the present invention, when one or a plurality of pairs of ventilation units are used, the air in the target region can be largely ventilated without leaving any stagnation. Furthermore, the air flow can be selected so as to eliminate the stagnation most according to the position of the ventilation opening in the target area, the arrangement of the ventilation fans, and the situation of the cutout.
