Paper presented at the 9th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Malta, 16-18 July, 2012.
The unglazed transpired solar collector uses the solar
energy to preheat ventilation air for buildings and
agricultural applications. The thermal performance of
transpired collector is depending on solar radiation
significantly. This study reports on the influence of capillary
heating system which is using as a supplemantary heating
system for non solar radiaton conditions. A theoretical and
experimental analysis were carried out regarding perforated
solar air collectors which is coupled to a capillary heating
system. Heat transfer effectiveness between capillary tubes
and solar collector is investigated for different conditions
such as mass flow rates, inlet temperatures.
