Background
People have increasingly increased requirements for comfort and air quality in home rooms, and good ventilation conditions are important guarantees for reducing indoor pollutant concentration and maintaining good indoor air conditions. The quality of indoor air is not only related to outdoor weather conditions, but also directly related to whether the indoor air can keep enough ventilation and air exchange with the outdoor. Building ventilation is divided into natural ventilation and mechanical ventilation, and for houses, natural ventilation is energy-saving and environment-friendly, and is a main method for improving indoor air quality. Windows are the medium of natural ventilation inside and outside buildings and are also important factors affecting indoor ventilation.
Because the space in the house is generally smaller, the opening mode of the window can influence the indoor ventilation condition to a certain extent. In modern buildings, the window opening modes are various, and common window opening modes mainly comprise an upper-hung window, a middle-hung window, a lower-hung window, a flat-open window, a sliding window and a vertical rotating window. Casement windows are the most common, most economical and practical type of windows, and most high-rise buildings at present also adopt casement windows. The window is characterized in that a hinge sliding support (four connecting rods and the like) is used for connecting a window sash with a frame on one side, and a handle is used for horizontally opening the window in the inside and outside or axially opening the window in the inside and outside on the other side. The flat-open window has the advantages that the opening area is large, the ventilation is good, and in the closed state, the rubber sealing strip is compressed in the frame groove and elastically deforms to form a complete sealing system, so that the flat-open window has good heat insulation, heat preservation, sound insulation and other performances; in the open state, the casement window can be completely opened, and the ventilation performance is better. Under the condition that the opening area is the same, the opening area of the casement window is twice that of the sliding window, and the ventilation effect is obviously better than that of the sliding window. However, since the casement window is time-consuming and laborious, complex to operate, inefficient when locking the window at a certain opening and closing angle, and most residents do not purposely fix the window, the window sash may be repeatedly opened and closed in windy weather.
