摘　　要：运用TRNSYS软件对我国北方地区太阳能供暖系统(SHS)建模研究,通过实验数据与仿真数据对比,验证了建立模型的正确性。在此基础上以室内热感觉预测平均投票数(PMV)为指标,运用TRNSYS软件研究了太阳能供暖系统流量、水箱体积与集热器的配比对PMV的影响。研究表明,在典型太阳辐照度下,一次回路流量为(2.3~2.8)kg/s,二次回路流量为(2.4~2.8)kg/s,PMV可维持在(+0.1~+0.2),PPD可维持在(7~11)%;在上述最佳流量下,储热水箱体积与集热器面积比为150L/m^(2)时,室内热舒适性可维持在(-0.15~+0.15)。这里的研究成果对我国建筑室内热舒适性及其评价标准的改进具有参考价值。TheTRNSYS software is used to study the solar heating system(SHS)in northern China.The experimental data and simulation data are compared to verify the correctness of the model.Based on this,the indoor thermal sensation prediction average vote number(PMV)was used as the index,and the influence of the flow rate of the solar heating system and the indoor variables on the PMV was studied by using TRNSYS software.Studies have shown that under typical solar irradiance,primary loop flow rate is 2.8kg/s,secondary loop flow rate is(2.4~2.8)kg/s,PMV can be maintained at(-0.25~+0.25);At the above optimal flow rate,the indoor thermal comfort can be maintained at(-0.15~+0.15)when the ratio of the storage tank volume to the collector area is 100L/m^(2).The research results of this paper have reference value for the improvement of indoor thermal comfort and evaluation standards in China.
