Development of a cost-effective and high efficiency low temperature non-concentrating black liquid collector. Interim report

Th primary objective of this project is to develop a cost-effective and high efficiency low-temperature non-concentrating black liquid type collector. A secondary objective is to determine if such a collector would have specific advantages when used as a thermal energy source for a heat pump. A third objective is to provide DOE and the solar energy community with some of the necessary technical and economic data to evaluate and compare a black liquid collector with conventional flat-plate collectors for other potential applications. Status and results are presented.
