Analysis of energy-saving of solar heating system in buildings in Yushu district

The paper makes an analysis of the heating load of solar energy in buildings in Yushu district with De ST software. The results show that the modified architecture has remarkable energy saving effect,energy-saving rate being 24%,27% and 31% respectively when room temperature is at 18 ℃,16 ℃,and14 ℃. Meanwhile,with Poly Sun software,the paper analyzes the energy saving of the solar heating system including the solar collector performance,system scale,installing angle,water tank volume,geographical position,geographical location,etc. The results of the analysis provide technical support for the popularization of solar heating system.
