Effect of Physical Parameters on Thermal Performance of Glazed Transpired Collector with Slit-Like Perforation

A glazed transpired collector with slit-like perforation was proposed in the paper, which improved corrective heat transfer coefficient without influence on collector area. Physical parameters on its thermal performance was studied by numerical simulation (Matlab Programming) and experimental research. Comparing simulated values to tested values of air outlet temperature, there's little difference, proving that the mathematical model was correct and could be used to in-depth study. Taking collected heat and air outlet temperature as evaluation indexes, simulation results showed that larger value of absorptivity of absorber outer surface was better for collector thermal performance, and lower values of emittance of cover outer surface and equivalent diameter was better for collector thermal performance.
