ON THE POSSIBILITY AND FEASIBILITY OF CREATING COGENERATION ENERGY SYSTEMS FOR INDUSTRIAL ENTERPRISES WITH SOLAR POWER GENERATION

Abstract

The purpose of this work is to determine the possibility of increasing the efficiency of solar radiation usage by creating cogeneration energy systems that simultaneously produce electrical and thermal energy.

Industrial enterprises are constantly increasing the capacity of their own energy sources to improve the efficiency of their main production and reduce electricity consumption from the power grid. Most often, solar converters located on the roofs of their buildings are used for this purpose. One of the drawbacks to maximizing the potential of solar radiation is the limited space available for solar collectors. The use of solar systems that can simultaneously produce electrical and thermal energy will significantly increase the amount of converted solar radiation in conditions where the space required for their installation is limited.

The paper considers the schematic diagram of the proposed cogeneration solar system and studies it based on the indicators of one of the industrial enterprises in Zaporizhzhia. It has been determined that when using water-cooled solar collectors, their total electrical and thermal power will be almost 4 times greater than when using conventional solar panels. The excess heat from the cooling system of such solar collectors can be used in the heat supply system of an industrial enterprise with the help of a heat pump. As a result of the proposed combination of these technical components (water-cooled solar collectors and heat pumps), a new cogeneration solar system can be created for industrial enterprises with greater electrical power and an additional and sufficiently large volume of hot water.
