THE EXPERIMENTAL PERFORMANCE COMPARISON OF TWO DIFFERENT TYPES OF UNGLAZED PVT COLLECTOR

摘要

This study analyzed the experimental results for the thermal and electrical performance of liquid PVT collector of two absorber types, a sheet-and-tube absorber type and a fully wetted absorber type. The thermal and electricity efficiency curves were calculated and it was shown that for zero reduced temperature, the thermal and electricity efficiency of the sheet-and-tube absorber PVT collector are 66% and 14%, respectively, and for the fully wetted absorber PVT collector they are 70% and 15%, respectively.
