|초록||This study was concerned with performance of 2 types of black painted solar air heaters, one is finned type heater, the other is mesh type. The performance test of heaters was made under the different operation conditions during winter season of December in Seoul area. It was analyzed and discussed by comparing the overall efficiency of 2 solar heaters at the same mass flow rate and ambient temperature.
Experimental results show that finned type solar heater is better than mesh type from the point of view of design and heat removal efficiency. Finned-type solar air heater supplies hot air up to 30 degree centigrade above ambient temperature with an overall efficiency of 47 percent while mesh type was 44 percent.
