Abstract
The scientific work “Research of recirculation systems and air recovery systems” is devoted to the analysis and selection of the most optimum ventilation systems that will reduce the cost of published products by reducing energy consumption. The purpose of this work is to discover and experimentally study the characteristics that affect the use of thermal and electric energy by ventilation systems and air heating in the industry, as well as to create solutions that allow to achieve a decrease in the consumption of fuel and energy resources for these systems. The relevance of the work is to reduce the cost of manufactured products and increase their own competitiveness by saving consumed energy resources. In this regard, the development of completely new solutions focused on the economic efficiency of electrical and thermal energy in ventilation and heating systems in various industries, with a simultaneous increase in sanitary hygienic efficiency, today is an urgent task of solving the problem and has economic national importance.
