Review article

The article presents the results of investigating the systems of natural supply and exhaust ventilation of residential premises with air supply through window structures. In particular, the analysis focuses on cases of air intake through a gap in tilting window sash and parallel opening window sash (room’s ventilation). There are provided the study results concerning the air velocity and temperature fields in the room`s volume, as well as the internal air temperature changes during the room’s ventilation in cases of active and inactive heating appliance. There is studied the air intake by the parallel displacement of the sash from the frame with formation of a gap in the living premises where heating convectors are used. The distribution of air flows is explored using STAR-CCM+ hydrodynamic analysis software package. The installation of window blocks in residential buildings with the function of parallel displacement of the sash allows for the standards-compliant air exchange in the premises without the use of special supply devices. When closed, the window block complies with regulatory requirements to heat transfer resistance and soundproofing.
