SOLAR HEATING SYSTEMS - STATUS AND RECENT DEVELOPMENTS

摘要

The paper gives a worldwide overview of the dissemination and major markets for solar heating systems. It also shows the contribution of solar plants to the supply of energy and the CO_2 emissions avoided as a result of operating these plants. Furthermore the paper gives an overview of recent system developments in the field of solar combisystems for hot water and space heating as well as in the field of large-scale solar heating systems for housing developments. Since the architectural integration of solar thermal collectors plays a major role concerning the broad acceptance of these systems, recent developments in façade integration are described. Finally promising new developments are presented in the field of solar heat for industrial applications.
