Abstract
The aim of the work is the analysis and development of energy efficient solutions for devices for utilization of exhaust air heat in ventilation and air conditioning systems, taking into account the dynamics of climatic and internal operating characteristics. There has been carried out the analysis of scientific, technical and regulatory documentation in the field of improving the energy efficiency of ventilation and air conditioning systems. The influence of life support systems on energy consumption in the world is shown. The description of a technique of technical and economic estimation of power characteristics of active utilizers which work in the conditions different from passport values is given. The influence of deviations of such operational factors as air consumption, outside air temperature before the utilizer, temperature and humidity of exhaust air is considered. A comparative analysis of ways to improve the energy efficiency of ventilation and air conditioning systems has been conducted. The article provides an overview of the main technological and economic barriers that prevent the transition of such systems to a qualitatively new level of energy efficiency. A reasonable choice from a variety of technical solutions is possible only with the introduction of energy and economic efficiency criteria that can be applied to different types of heat recovery systems in ventilation and air conditioning systems. Therefore, the development of new approaches to the analysis of long-term operation, which allow in the early stages of project activities to predict the economic and environmental effects of specific devices in the given conditions of operation of ventilation and air conditioning, is an urgent task.
