摘要
利用年度化费用的方法对地面辐射采暖进行了热经济分析,研究发现,存在最佳的采暖管间距,使得采暖的年度化费用达到极小值,最佳管间距根据管材费用,供水平均温度和燃料的火用单价确定。与散热器采暖比较,地面辐射采暖节约能耗费用大约50%。地面辐射采暖的最小年度化费用比散热器采暖的年度化费用减少10%左右,是一种值得推广的经济节能型供暖方式。
The annual cost method is adopted to analyze the heat economics of radiant floor heating. The study shows that there exists the best pipe space for the least annual cost. The best pipe space is decides by the pipe price, the average temperature of supply water and the fuel＇s exergy price. Compared with the radiator heating, the radiant floor heating can save approximate 50% of energy consumption. The annual cost of the radiant floor heating is 10% lower than that of the radiator heating.
