Abstract

Solar air heater with one glass cover was tested with solar simulator at the radiation values of 650-700 W/m2. The test followed the standard of The American Society to Heating, Refrigerating, and Air-Conditioning Engineers, Inc. (ANSI/ASHRAE 93-1986). Air mass flow rate per unit collector area (G) at the values of 100, 150, 300, and 350 kg/h-m2 approximately and geometric coefficient of the collector (K) at the values of 100, 250, 600, and 800 approximately were varied in the test. Results are described that the efficiency of solar air heater was increased with the increasing of G and K obviously and had increasing linear relationship with the product of G and K.
