This investigation is concerned with the unglazed
transpired solar collector (solar wall) type. With this purpose, the optimum
hole arrangement has been determined by investigating the effect of hole diameter
and pitch on the thermal efficiency of the system for different environmental
condition. A thermodynamic model is used to simulate the heating process within
the system. As a result, for extremely small hole diameters or extremely large
hole pitches, the system works as a Trombe wall (glazed thermal storage wall)
rather than an unglazed transpired solar collector because of the fact that
there is not enough air flow through the absorber.
