Development of a Solar Total Energy System : Summary of Experimental Results

Abstract

The operation of a solar total energy experimental facility, which generates heat energy and electric power by solar energy, had been initiated in September 1982. This facility is operated by selecting one of three operating modes according to the conditions of insolation and storage temperature of a heat storage unit. Furthermore a load control mode is provided with the aim of supplying either more electric power or heat energy. In a previous report, the outline of the facility and experimental results of operation by an electric load control mode were reported. Based on these results, a part of the heat collection loop and low temperature heat recovery loop was remodeled to increase the system efficiency. In this remodeled facility, experiments on the heat load control mode were carried out and a summary of all the experimental results is described in this paper.
