Abstract
The changing regularity of temperature in hot water tank and load of building reached under the unit area of collector was obtained according to the undulations of solar radiation intensity and load of typical buildings in Nanjing area , and the time for tank with different volumes to start-up was analyzed in summer and winter. The results show that the performance of the household air conditioning system is impacted by the volume of the tank : in summer , under the unit area of collector and the tank of 70L, with the volume increased by 114% , the range of the tempertature of hot water decreased by 54% and the building area of the load decreased by 25.2% , at the same time, with the volume increased to 150L, the time for start-up is twice longer than before, that said, it was better, the tank smaller, but the minimum volume is existed , which with the extending of working time bigger and bigger ; in winter,the effect of the tank volume on the load is small , but the time for start-up is 4 hours longer in summer than in winter , with the tank of 70L.关键词
