| 摘 要： | 针对太阳能跨季蓄热量利用不充分的问题,提出了一种多方式可调节供暖系统模型,利用温差控制原理实现系统供暖方式的自动转换.以乌鲁木齐地区某公共建筑为例,采用TRNSYS动态模拟软件对多方式可调节供暖系统进行了全年运行分析.结果表明:15 100 m3的蓄热基坑体积与6 040 m2的集热器面积恰好匹配;在非供暖期蓄热基坑内...

| Abstract: | Aiming at the problem of insufficient utilization of seasonal heat storage,a multi-party adjustable heating system model is proposed,and the automatic conversion of heating mode is realized by using the principle of temperature difference control.An example of a public building in Urumqi area is given,and dynamic simulation software TRNSYS used to analyze the operation of multi-mode adjustable heating system throughout the year.The results show that the volume of the heat storage pit is 15100 m3,which exactly matches the size of the collector area of 6040 m2.In the non heating period,the heat stored in the foundation pit can reach 7528.11 GJ,which can bear 85.06%of the building heat load,and the remaining 14.94%is supplied by electric energy.Compared with the traditional heating system,under the same building heat load,the multi-mode adjustable heating system can save 256.84 t of fossil fuel standard coal and 211520.09 m3 of natural gas.The average solar energy guarantee rate in the whole heating period can reach 73%. |
