Efficiency and exergy analysis of a new solar air heater

Kurtbas, İrfan; Durmus̨, Aydın - In: Renewable Energy 29 (2004) 9, pp. 1489-1501

It would be misleading to consider only the cost aspect of the design of a solar collector. High service costs increase total costs during the service life of solar collector. The most effective way to save energy is by increasing the efficiency in a solar collector by the heat transfer coefficient.

Effect of aspect ratio on the collector efficiency of sheet-and-tube solar water heaters with the consideration of hydraulic dissipated energy

Yeh, H.M.; Ho, C.D.; Yeh, C.W. - In: Renewable Energy 28 (2003) 10, pp. 1575-1586

collector efficiency of sheet-and-tube solar water heaters has been investigated theoretically. As the collector area and the … distance between tubes is fixed, the collector efficiency increases with increasing collector aspect ratio (i.e., either …
