A Comparison of Unglazed Flat Plate Liquid Solar Collector Thermal Performance Using the Ashrae Standard 96-1980 and Modified BSE Test Procedures

摘要

The report reviews the BSE procedure and summarizes the ASHRAE Standard 96-1980 for testing unglazed solar collectors. The ASHRAE procedure consists exclusively of outdoor testing, whereas the BSE procedure requires a combination of outdoor and indoor testing (no irradiation) to determine the collector optical and thermal loss characteristics, respectively. Two unglazed flat plate liquid solar collectors were tested according to ASHRAE Standard 96-1980 and BSE procedures and the results compared. During the indoor BSE thermal loss tests blowers were used to simulate winds of 0-3.9 m/s (0-8.72 mi/hr) to investigate the wind effect upon collector thermal losses.
