The Analysis Of Solar Energy On Heating System

Because of lacking normal energy and backward economy, the public heating system has not been established in Tibet. Since there is lots of cheap and high-quality solar energy, it is important to discuss how to use the solar energy in Tibet.From the experiment of solar energy heating system established in Tibet, it can be seen that the heating system can meet the requirement of office heating in Tibet. In light of the experiment data, we analyzed the performance of the system. Then the momentary and daily mean efficiency of solar energy collectors was made. It provides the theoretical basis for the application of solar energy heating systemMoreover, numerical computation method was used to calculate and simulate the distribution of velocity and temperature in the water tank. According to the calculated result, the influence of different factors to the heat transfer was analyzed in this paper, especially about the effect of baffle plate and inlet velocity. And the result of experiment was made to verify the result of numerical compution.Compared with the experiment results, the numerical computation and analysis were testified to be resonable. At last, an analysis about the application and popularization of the solar energy heating system were made in Tibet was made.
