中文摘要:
      储热水箱被广泛使用在太阳能集热系统以及家用电加热热水器中,是决定集热系统和热水器性能的关键因素之一,储热水箱分层效果的好坏决定了集热系统的效率及热水器的热水出水量.绘制了直接进口和三层孔板两种储热水箱结构图,通过设计试验系统,搭建储热水箱分层特性测试试验台,收集了两种结构水箱在相同的初始水温、不同流量时水箱各层温度随时间的变化数据并绘制成图.同时基于热力学定律,分析对比了相同进口结构、相同初始进出水温差取出效率随时间的变化.在初始温度50℃、流量为1.1和4.2 kg·min-1的工况下,对比了不同结构的MIX数对储热水箱分层性能的影响.
英文摘要:
      Water storage tank is widely applied in solar heating systems and household electrical calorifier.It is one of the key factors that determines the performance of heating system and calorifier,and its stratification effect determines the efficiency of heating system and the outlet of hot water.In this article,structure charts of two different heat storage tank(direct import and three-hole orifice) are drawn.The experimental system and the construction of stratification test-bed was designed.The change data of the temperature of each layer in the water tank at the same initial water temperature and different flow rate were collected and plotted.Meanwhile,based on the law of thermodynamics,the change of the extraction efficiency of the same imported structure and the same initial inlet/outlet water temperature is analyzed and compared.Under the condition of initial temperature of 50℃,when the flow rate was 1.1 and 4.2 kg·min-1 respectively,the influence of MIX number of different structure on the layered performance of heat storage tank was compared.
