[Problems to be solved by the invention]
As described above, various inventions such as an air barrier ventilation system at the window and its blower have already been proposed, but these conventional techniques are premised on the design and construction of the building at the first construction. In other words, it uses a space under the floor or behind the ceiling to form a comfortable living space systematically for the prevention of condensation, air conditioning, ventilation, and heat load. It is thought that each has usefulness and specificity.
However, there is no description in any of these prior arts regarding measures for cold drafts of window glass facing outdoors (especially inhibiting the heating effect in the room during winter) in buildings that have already been constructed. In this sense, there are problems in terms of the heating / air-conditioning effect and its management / maintenance.
[0005]
The present invention has been made in view of such a problem, and it does not matter whether an existing air conditioner (such as a ceiling or ceiling mounted type, a package type, or a floor type) is used in an already constructed building. Therefore, the present invention provides a fan device for assisting air conditioning having a configuration in which a comfortable living state (especially, a cold draft countermeasure in winter) is effectively exhibited and maintained by simple construction.
[0006]
