家用太阳能热水系统的仿真研究

太阳能热水系统是一种成熟的太阳能利用方式,利用集总参数法建立了系统主要部件太阳能集热器和储热水箱的数学模型,并通过TRNSYS瞬态模拟软件对该系统的进行了仿真,探究了当集热器面积,水箱容积和集热器安装倾角发生变化时水箱出水温度随时间的变化情况。仿真结果表明,在一定范围内,水箱出水温度随着集热器面积的增加和水箱容积的减小而逐渐增加,但集热器倾角的变化对水箱出水温度的影响较小。

The solar hot water system is a mature solar energy utilization method.The lumped parameter method is used to establish the mathematical models of the solar collectors and hot water storage tanks of the main components of the system.With the TRNSYS software,the change of the outlet temperature of the hot water storage tank with time is explored when the area of the solar collector,the volume of hot water storage tank and the installation inclination angle of the solar collector change.The simulation results show that within a certain range,the outlet temperature of the hot water storage tank gradually increases with the increase of the solar collector area and the decrease of the tank volume,but the change of the collector inclination angle has little effect on the outlet temperature.
