The present invention relates to a ventilation device for preventing condensation that can be installed on a frame such as a window, and a louver window equipped therewith.

The phenomenon in which water vapor liquefies as air containing water vapor cools is called condensation. In general, condensation often occurs in buildings during the cold winter months. Condensation occurs when the hot, humid air inside comes into contact with the cold inner surface of the outer wall. Condensation is the main cause of mold growth. If condensation is left unattended for a long period of time, mold may proliferate on walls and ceilings, causing unpleasant odors and especially causing diseases such as allergic rhinitis, asthma, and dermatitis.

To prevent condensation, it is necessary to lower the indoor humidity or lower the temperature difference between indoors and outside. However, in the cold winter, heating is used to increase the indoor temperature, and humidifiers are used to prevent respiratory diseases. Therefore, it is very difficult to effectively prevent condensation occurring inside a building.
