By: W.L. Gemmell and M. Chandrashekar, University of Waterloo and K.H. Vanoil, IST Energietechnik GmbH
This report describes several numerical models developed for the detailed simulation of solar energy systems. The report documents various models and validation of the models against measured results. A detailed characterization of each of the evacuated collectors and detailed models are provided.
The Development of Mathematically Highly Condensed Computer Simulation Models
1987 - PDF 0.48MB
By: Konrad R. Schreitmüller, Institut für Solarenergieforschung
This report has a two-fold purpose. The original intention was to document the IEA Solar Heating and Cooling Task VI work on simplified models, which centered on Input-/Output (I/O)-based methods. However, in the course of model development and improvement, these methods became more sophisticated, complicated, and detailed, so that now the most highly developed one has a level of sophistication comparable to most "detailed" programmes. Thus the term "simplified" is not longer applicable to all these models.
Design Guidelines for Evacuated Collector Solar Energy Systems
December 1986 - PDF 1.57MB
By: D. Buchen, Buchen, Lawton, Parent Ltd, Canada
This report familiarizes designers with the very different characteristics of different evacuated collectors to indicate where evacuated collectors are appropriate in a solar energy system, and to provide design guidelines to aid in integrating evacuated collectors into a system.
