PASSIVE METHOD TO DETERMINE SHADING COEFFICIENT USING TWO NATURALLY VENTILATED AND TRANSPARENT BOXES.

Author(s) : SHUKUYA M., KIMURA K.

Summary

AN EXPERIMENTAL METHOD FOR DETERMINING THE SHADING COEFFICIENT FOR WINDOWS WITH INTERNAL SHADING DEVICES WITHOUT USING A REFRIGERATION MACHINE IS DESCRIBED. THE METHOD REQUIRES 2 NATURALLY VENTILATED AND TRANSPARENT BOXES. ONE OF THE BOXES IS FOR GLAZING WITH INTERNAL SHADING AND THE OTHER FOR A STANDARD CLEAR GLASS PANE WITHOUT SHADING. THE SHADING COEFFICIENT CAN BE DETERMINED FROM THE SOLAR OPTICAL PROPERTIES MEASURED AND THE HEAT TRANSFER COEFFICIENTS ESTIMATED FROM THE HEAT BALANCE AT THE SHADING AND THE GLASS. THE VALUES OF THE SHADING COEFFICIENT OBTAINED FROM THE PRESENT TESTS WERE FOUND TO BE QUITE SIMILAR TO THE ONES LISTED IN ASHRAE FUNDAMENTALS.
