EN Energy system efficient performance and energy policy

Abstract

The 2020 crisis caused by COVID makes the global economy move forward to a new start. In order to achieve strategic goals, the energy sector and the HVAC&R sector forced by faced problems to energy efficiency projects and technologies development and deployment to get fast return on investment and to manage risks for the secure step forward. To meet strategic packet goals global community should redirect investment into the renewables technologies development to integrate them with the energy efficiency projects in the project design phase. On the study of the solar thermal system due to increasing the outlet temperature of ground source heat exchanger it is possible to observe floating increasing COP (opera­ting mode dependence) for the HP system by 4-6%. For getting the greater angles of the collector, the more of the inbound energy can be accumulated and used per annual year. For that reason, collectors intended for the maintenance of HP system, when installing at a large angle. It can reduce the amount of excess heat in the summer season, while the efficiency of the collectors in winter season falling under a smaller angle optimized. The increasing of the COP is caused by reducing of the electrical input to the heat pump cause higher temperature level gain by solar collector. The use of solar thermal collectors bring possibility to reduce borehole depletion. In own turn it can be used for ground heat exchanger regeneration during heat pump stand by. Ukraine can look for the best practices of the sustainable deve­lopment goals worldwide and adopt them by modifying for actual complex tasks due to actual regulations and development new ones to motivate industrial players on the national and global levels for driving sectors development along with the sustainable development scenario
