Experimental Study and Trnsys Simulation on Domestic Solar Water Heating System

Based on the principle of thermodynamics and heat and mass transfer, taken TRNSYS as the simulation plat-form, this paper presents the dynamic model of solar water heating system, in which the incident radiation, the incident scattering, the wind speed and other factors were considered. An experiment on a solar water heating system was carried out, and the simulation validity will be proved by the experimental data. The results show that the model has high accuracy and are suitable for system simulation.
