PURPOSE: A ventilation window by natural circulation is provided to obtain a partial ventilation function without large changes in the existing structure of window sash and frames. CONSTITUTION: A window system with a natural circulation function comprises a window frame(10), a pair of window sashes(20), a ventilation panel(30), and a receiving unit(40). A horizontal rail(11) and a vertical rail(12) are formed along the inner peripheral surface of the window frame. The pair of window sashes are coupled to the horizontal rail and allowed to slide, and the pair of window sashes have fastening parts(21) on a side corresponding to the vertical rail, in which the ventilation panel is installed. The receiving unit is formed along the vertical rail and selectively receives the ventilation panel by sliding of the window sashes. |
