Trombe Wall Performance Study in the Upper-Midwest. Final Report

摘要

The objective of the project was the study of the performance of Trombe wall systems when used in the Upper-Midwest. This was accomplished by building two highly instrumented full Trombe wall models. The data acquisition system was based on a 6502 microcomputer and permitted data points to be obtained every 15 minutes during each operating day. After obtaining base-line data, the configuration of one of the models was varied in a controlled manner to determine performance effects of important variables such as natural convection through vent ports or insulting shutter effects in front of the wall. Finally, a thermal diffusion model is used to make performance calculations for the Trombe Wall models. The experimental data compares well with the diffusion model calculations. The conclusions of this study provide suggestions on the use of Trombe Wall systems in the Upper-Midwest climate. (ERA citation 08:012156)
