Abstract

The purpose of this study was to evaluate the performance of a solar collector to introduce natural convection in a water tank as a means of obtaining warm water. Numerical analysis was performed to predict the characteristics of the solar collector and its performance was verified using an experimental method. The single vacuum structure of the collector enabled natural convection when it was fitted on the water tank. Based on numerical analysis, warm water of $31-54^{\circ}C$ was obtained when the inlet temperature of cold water was $20^{\circ}C$. Furthermore, the temperature of the warm water could be predicted under various conditions as well as the experimental conditions created for this study.
