Abstract
Now, the issue of protecting the environment and reducing the use of fossil non-renewable energy sources is becoming increasingly important. For modern heating and air conditioning systems, it is imperative to reduce emissions of harmful substances, especially CO2. This can be realized by significantly reducing the use of fossil non-renewable fuels and reconstructing engineering systems to the current level of energy saving. The annual growth in demand for fossil fuels will be reduced through the optimization of substations and heat distribution devices, which is a necessary step for the development of the country's industry and economy. Therefore, today the main task is to increase the energy efficiency of the use of resources and increase the potential of alternative types of energy in combination with modern low-temperature energy-efficient heat distribution systems, one of which is radiant water panels. The article presents the results of improving the method of mounting beam-ceiling fixtures with respect to their orientation in space. The results of numerical calculations indicate the efficiency of mounting the equipment at an angle of 45 degrees, which increases the efficiency by 10% in relation to the 0° orientation. The results of calculations and measurements show that the use of radiant heating in a lateral or longitudinal direction at different angles allows to significantly reduce the cost of energy resources for heating at low temperatures and at the same time not to lose the speed of operation to changes in external temperature parameters. The most effective of the variants of the experiment turned out to be the variant of suspension at an angle of 45°, in which an increase in efficiency by 10% in terms of final temperatures was found, which in turn makes it possible to reduce the use of thermal energy and reduce the amount of necessary equipment in design calculations. At the same time, installation difficulties were not detected.
