Abstract
On the basis of studying inter-thermal performance of U-tube solar collector, the transient efficiency and efficiency factor were got. As for analyzing the thermal performance of the collector from different angles, two models were developed. By using numerical method each part of the collector were got. Furthermore, by weighted least square method, the instantaneous efficiency of solar collector was got. Experimental results coincide with theoretical calculations well.
