- Abstract
- Thermal performance measurements of eight types of liquid-heating flat-plate solar collectors were conducted with two to four collectors of each type of four outdoor test sites. Tests were performed in accordance with the procedure prescribed by ASHRAE Standard 93-77. Statistical analysis of data sets for each collector type within test sites and between tests sites was done using ASTM recommended methods to evaluate test method measurement uncertainty.
