Abstract:

In this paper, the optimum orientation and sizing of a thermosyphon flat plate collector−storage solar water heating system were determined using the typical meteorological year data for Adana, Turkey. The typical meteorological year data for the location was taken from Meteonorm software, and the daily hot water consumption was estimated by utilizing the Rand hot water profile. A transient modeling was carried out for the prediction of a full year system performance through the use of the System Advisor Model simulation program. The effects of the collector area, the storage tank volume, the daily average delivery temperature and the daily hot water consumption on the annual solar fraction were analyzed by the presented simulation model. Results showed that the optimum tilt angle for a due south-facing solar collector is found to be 35.0° for maximizing the annual solar fraction. The collector area and storage tank size greater than 3 m² and 100 L respectively have little effect on the solar utilization.
