IMPROVING THE EFFICIENCY OF USING WATER RADIANT HEATING SYSTEMS

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 advantages of radiant heating are the absence of dust transfer, since the convective process of mixing air masses is remote, does not require the connection of electrical power, it is possible to work with low-temperature sources of heat supply, no maintenance is required, since there are no fans, electric motors, bearings, lubricants, filters, etc. The main advantage can be distinguished from the use of additional equipment for destratification, as there is no overheating of the upper zones of the heated building. 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. By achieving this mounting and installation option, the required capacity of the heat supply source is reduced and the amount of energy resources used is reduced.
