ON THE ISSUE OF STUDYING THE INFLUENCE OF STRUCTURAL FEATURES OF DOUBLE-GLAZED WINDOWS ON THE TOTAL HEAT LOSS OF BUILDINGS

Issues of the effective functioning of life support systems are always relevant and are reflected in the works of leading scientists. Consideration of the possibilities of reducing heat loss at all stages of transportation and operation is a promising direction in modern research. Heat supply refers to energy-intensive processes, heat losses in various areas are inevitable, so it is necessary to develop and improve measures that will minimize these losses and increase the efficiency of heat use. Calculations of heat losses are regulated by regulatory documents. Heat losses in buildings include losses through enclosing structures (walls) and losses through windows. Given that the area of window openings is significant, heat losses through windows are an important parameter that must be taken into account. Currently, it is possible to use various double-glazed windows that contribute to improving energy saving indicators. In addition to conventional single-chamber and double-chamber double-glazed windows, it is possible to use double-glazed windows filled with inert gas. The main advantage of single-chamber double-glazed windows is that they have a lighter construction, while filling with inert gas requires additional costs. The paper presents a comparative analysis of heat losses through window openings for four different designs. Heat losses through enclosing structures are considered. Data on losses resulting from infiltration are obtained. The total heat losses are shown. Analytical dependencies of heat losses on the outside air temperature are presented.
