Abstract :Condensing Gas Water Heater has received extensive attention and was widely used due to its
high efficiency and low pollution, the study of condensing gas water heater in domestic is still in its infancy, and the testing is mainly based on (Condensing domestic gas instantaneous water heaters》 CJ/T 336-2010, This article elaborated the heat and humidity balance of condensing gas water heater, and a further illustrates has been shown through experiment research, what's more, the definition and significance of corrected heat load which is mentioned in the standard has been discussed in order to deepen the understanding of the standard.
Keywords:Condensing Gas Water Heaterheat and humidity balancecorrected heat load
1前言
冷凝式换热技术起源于欧洲，最早被应用于锅炉， Carlyle Ashley于1928年设计了一个被称为“Weather-maker”的燃气专利产品，这是第-个将烟气中水蒸气的冷凝用于采暖空调领域的高效率燃气加热炉！，而冷凝式热水器是在20世纪70年代末出现的，工作原理和冷凝式锅炉相似。冷凝式燃气热水器通过二次换

热利用烟气中水蒸气相变释放出的潜热，进一步降低排烟温度，热效率比普通的燃气热水器提高15%左右，同时烟气中的SO，等酸性气体溶于冷凝水，烟气得到净化，达到高效环保的目的。
冷凝式热水器在欧洲国家的发展已经相对成熟，产品已占热水器总量的15%以上，国内对冷凝式热水器的起步相对较晚，相应的标准规范也并不成熟，目前冷凝式家用热水器测试标准主要采用《冷凝式家
