Optimization of combined operation of heat pump and active solar system

The energetic policy of the European Union member states is focused on the usage of alternative power sources. Increasing interest in the alternative power sources such as heat pumps, solar energy and wind energy has appeared recently. Many utilizable energy resources have insufficient thermal potential for its direct usage. The aim of this paper is to specify application area of heat pumps within combined heat systems. The main invention is the optimization of designed combined system of a heat pump and an active solar system. The paper explains new possibilities of heat pumps usage in the common power units. The result of applied research is an examination of heat pump and active solar system cooperation eligibility. The aspects of such cooperation are examined mainly from the energetic point of view, but the economical parameters of the combined system are pointed as well. The results and conclusions are supported by observing the existing combined system assembled at the Department of Electrical Power Engineering at the Brno University of Technology.
