Description

{Duct Device}

The present invention relates to a ventilation device, more particularly, to a natural circulation type ventilation device that is disposed at the upper and lower portions of a window and is operable at the same time so that the ventilation device can be easily operated while the indoor / outdoor air circulation is natural circulation type, .

Generally, when a person stays in a room for a long time, for example, when a residential space is kept in a closed state, the concentration of oxygen in the air is reduced and dust increases, and the air becomes cloudy. Air and outdoor air were exchanged. However, when the window is opened to ventilate the intruder can enter the room through the window, and when there is a large temperature difference between indoor and outdoor areas such as winter, a large amount of air is replaced at one time, .

In addition, the enclosed indoor space causes the breeding of molds on the floor, walls and windowpanes of balconies due to insufficient ventilation, thereby threatening the hygiene environment or causing gas, dust, smoke, odor, &Lt; / RTI > Meanwhile, in order to solve the above-mentioned lack of ventilation of the indoor space, a forced ventilation method using a mechanical device such as a ventilator or a grill or the like is attached on one side frame of a window or a ventilator is arranged vertically However, this is merely a function of removing and renewing the indoor air, but it is disadvantageous in that it does not improve the indoor environment such as insulation, sound insulation and watertightness.

In addition, the conventional ventilating device disposed at the upper portion does not provide a satisfactory air circulation between the indoor air and the outdoor air, and the ventilating device which is arranged long in the upper and lower portions does not provide a satisfactory ventilation, There is a problem that the insulation between the outdoor unit and the indoor unit is insufficient due to the structure of the ventilation device.
