常压容积式燃气热水器热效率测试方法的探讨

The study of the measure method of efficiency of gas water heaters containing water

针对增多的容积式燃气热水器 ,按照国家标准测试 ,其热效率相对于快速热水器比较小 ,不符合实际情况 ,对于运行功率和费用的计算会产生误导 ,因此提出了新的方法 ,试验结果表明 ,在运行状态下进行测试 。

This paper describes the new measure method of heat-efficiency of gas water heaters containing water. In accordance with the method of the national standard, the heat-efficiency of the heaters is lower than one of the gas instantaneous water heaters, which is tested in accordance with another standard. This doesn't accord with the actual case. This data of heat-efficiency is misleading for the measuring of the efficiency and cost of running of the heaters. A new measure method is brought forward after many experimentation. Pass many test and analysis of the measure data, the method is feasible for practical case.
