Research Applied to Solar-Thermal Power Systems.

摘要

This report documents the research and development efforts during the period from July 1, 1973to December 31, 1973. A scaled model of a solar collector module has been designed and fabricated. Life testing of candidate mirror coatings for the solar concentrator have continued. The performance of solar absorber coatings at various elevated temperatures has been investigated. Heat pipe tests were performed to examine the compatibility of stainless steel and copper containment materials,with water as a working fluid. The night-time cooling and subsequent early morning warming of the pipelines and other fluid-carrying components of the transfer loop were analyzed. Computations were performed to determine the effect of daytime variations of insolation on the heat losses and pumping energy. Steady-state operating characteristics of three transfer loop configurations were computed.
