The object of research is ventilation systems in civil low-rise buildings of urban development and current equipment used to reduce energy consumption. The given work examines the application of energy-efficient technologies in ventilation systems of residential facilities. The work was carried out on the basis of foreign and domestic literary sources and Internet resources. The problems of inefficient use of energy resources were identified, and ways to improve energy efficiency for the residential sector through the introduction of recuperators were considered. A comparative analysis of existing systems of heat exchanger outlet air, the advantages and disadvantages of these systems in terms of their energy efficiency were revealed. To substantiate the application of the computational model, a two-storey residential brick house was designed, a heat engineering calculation was carried out, and enclosing and translucent structures were selected. Finally, based on the results of the calculation, a technical solution was proposed that justifies the positive economic effect of using exhaust air heat recovery by comparing the values of heat loss by the building before and after the installation of the recuperator. |
