Studies have shown that the glazed transpired solar collector (GTC) with a chimney has efficiencies higher than those obtained from a typical glazed non-transpired solar collector (GNTC) in natural convection mode. However, there has not been a direct comparison of the performanc...

Transpired solar collectors require adequate pressure difference across them to work and electric fans usually produce the pressure difference in forced convection mode. In natural convection mode no fan is used and little or no pressure is produced across the collector. A chimne...

A glazed transpired solar collector (GTC) was set up to operate in natural convection mode. Collector air temperature and velocity were measured at specific points in the collector. Solar radiation, ambient temperature, collector cover glass and absorber temperature were also mea...

The field performance of palm fibre insulation board treated with cassava starch solution has been studied. This was done in search of local substitutes for imported insulation materials used in low temperature (45°C – 200°C) ovens. Fresh oil palm fibre was collected from palm-ke...
