Increase of Efficiency of Energy System with Heat Pump Using Solar Radiation

Abstract: Present energy policy of European Union appears to be in a period of dynamic progress. Currently the primary aim is to ensure the energy stability of European Union member states mainly with the usage of renewable power sources. Great attention is paid to increase of efficiency of energy systems operation. The paper presents the results of research in the filed of alternative power sources utilization. The possibilities of increasing the alternative power sources operation in terms of its mutual cooperation are mentioned above all. The research is focused mainly on new possibilities of utilization of heat pumps in connection with active solar system. Aspects of such connections are reviewed mostly from the energy point of view but the economic parameters of this assembled system are pointed as well. The results of long-term measuring on the active solar system assembled in the university laboratories are presented in the paper. The research showed that the new approach to a cooperation of heat pump and solar system working in a common power unit leads to increase of heating factor of heat pump and high efficiency of solar system which finally decreases the demands on primary energy
