Paper presented at the 9th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Malta, 16-18 July, 2012.
An experimental device was design and built to evaluate the performance of a solar water heating system. Flat-plate solar collectors system were studied considering parallel configuration. Temperature sensors (k type thermocouple), a differential pressure transducer, a turbine type flow meter, and a pyranometer (global solar irradiance) were installed at strategic points for continuous monitoring. The studied parameters were: temperature at the inlet and outlet of the solar collectors and of the tank, heat absorbed by water, pressure drop and mass flow of water. The result shows the performance of the solar collectors system in specific conditions of the Arequipa city in Peru.
