Теплозахист будинків і споруд системами теплолокалізаціі

Every year the problem of energy saving in the modern world is becoming more and more actual.Energy saving - involves the very economical use of energy resources, because natural resources are exhaustible, costly, and their production in most cases is harmful to the environment. Life support systems for the comfortable staying of people in buildings and facilities of various purposes are among the most significant consumers of fuel and energy resources. There are many possibilities for developing energy-saving technologies in this area. One of the important directions in saving energy resources in the operation of buildings is to improve the systems of body protection of buildings and structures of the communal and industrial sector. Actual is the realization of thermal protection of buildings in the case of breakthroughs of cold air in the heated premises when opening external doors and gates. This is one of the most important aspects of thermal protection during the installation of heat localization devices installed in open spaces. In the study of the operation of heat localization devices, a flat nonisothermal jet emanating from a rectangular steel nozzle located in the plane of an open external opening was divided into many small jets propagating in the same direction, emanating from slots of the same size with the same speed, separated from each other by a distance equal to the width slit. The air flow rate was determined, graphical dependencies were obtained. With the help of mathematical modeling, an adequate picture of the physical expiration process was obtained. At the initial stage, these streams were merged into a single air flow, and as a result, cold outside air was not allowed to enter the heated premises of buildings and structures, thereby reducing the heat consumption of the heat localization devices. indoor climate, increases the efficiency of the means of thermal protection of buildings and structures.
