Abstract :This investigation is concerned with the unglazed transpired solar collector insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
Keywords : Unglazed solar collectors, solar wall, hole diameter, pitch, efficiency
