Experimental study and first thermodynamic law analysis of a solar water heater system

Abstract

The performance of a pilot scale at plate solar water heater system is investigated theoretically and experimentally. The e ect of the operating conditions and characteristic factors of the collector on the system e ciency is studied. A conceptual mathematical model is developed in order to analyze the system behavior in di erent operating conditions by considering the physical and constructive aspects of the system. The accuracy of the model result is estimated by comparing the model results with the existing experimental data. The highest obtained system thermal e ciency is 45%, and the optimum local values for surface azimuth and tilt angles are obtained at 180 degrees from north and 33 degrees, respectively, for the constructed solar water heater in Isfahan, Iran, with the local latitude of 32.6333 ∘ N.

Review of Phase Change Materials Based on Energy Storage System with Applications

“…[12] She describe the storage .The energy interns of temperature distribution heat transfer and energy storage rate by using multi tank storage system. [13] The solar energy storage based on the metal hybrids particularly to get the better performance, optimization and good economical feasibility. [14] He describes that energy storage system based on latent heat storage and thermo chemical heat storage mainly concentrate on limited life of methods energy source is the achievement of sustainable energy is not available at all the time the need of heat storage system obtained.…”
