摘　　要：为减少传统能源在生活中带来的环境污染问题,进一步提高用户生活质量,降低用户生活成本,设计了以铝排管平板集热器为主的变流量太阳能热水系统,依据蓄热水箱热源侧出口温度与铝排管集热器出口温度的差值进行系统的变流量控制运行。以包头市气象条件为例,对分时段供水量、集热器面积和蓄热水箱等参数进行了设计,在trnsys软件中进行了仿真模拟,从蓄热水箱出口水温、用户侧出口水温及耗电量分析来看,该太阳能热水系统的全年出口平均水温均可维持在55℃以上,且使用成本比利用传统能源降低了38.4%。In order to decrease the environmental pollution caused by use of traditional energy sources and further improve the quality of life of residents and reduce their cost of life,a variable flow solar water heating system with flatplate collector of aluminum exhaust pipe as the main part was designed.According to the difference between the heat source side outlet temperature of the hot water storage tank and the outlet temperature of the aluminum tube collector,the variable flow control operation of the system is performed.Taking the meteorological conditions of Baotou City and the parameters of water supply,collector area and hot water storage tank in different periods are designed.The simulation is carried out by Trnsys software.From the analysis of water temperature at the outlet of hot water storage tank,and water temperature at the outlet of user side and power consumption,it can be seen that the annual average water temperature at the outlet of the solar hot water system can be maintained above 55 ℃,and the cost of using energy is 38.4% lower than that of using traditional energy.
