摘要
为了研究双水箱蓄热供暖系统的水箱体积对系统的影响,基于包头某办公建筑研究双水箱蓄热供暖系统的性能.利用TRNSYSY仿真软件建立双水箱蓄热供暖系统仿真模型,通过误差分析验证了模型的正确性.基于建立的仿真模型以系统的经济性和室内热舒适性为优化指标,对系统进行优化.结果表明:在此实验条件下,集热器面积与水箱总体积不变,集热水箱与供暖水箱体积比为1.5时系统性能最优,此时系统与优化前相比较太阳能保证率增加2.35%,辅助热源的能耗降低15.02%.
Abstract
In order to study the influence of the water tank volume on the dual tank heat storage and heating system,the perfor-mance of the dual tank heat storage and heating system was studied based on an office building in Baotou.Trnsysy simulation software is used to build the simulation model of double tank heat storage heating system,and the correctness of the model is veri-fied by error analysis.Based on the established simulation model,the system was optimized with the system economy and indoor thermal comfort as the optimization indexes.The results show that:Under the experimental conditions,the area of the collector and the total volume of the water tank are unchanged,and the volume ratio of the collecting water tank and heating water tank is 1.5,the system performance is optimal.Compared with before optimization,the solar guarantee rate of the system is increased by 2.35%,and the energy consumption of the auxiliary heat source is reduced by 15.02%.
