Through the analysis and research of CFD, on the premise of satisfying the performance of gas water heater, the project about adding the stainless steel condenser in the ordinary forced type gas water heater was designed. Furthermore, in order to analyze the feasibility of this new design, the contrast experiment between the new-designed gas water heater and the original one was conducted.% 对普通强排恒温燃气热水器上进行了增加不锈钢冷凝器的实验,通过 CFD 分析研究得到的在满足热水器热水性能的前提下所设计的采用不锈钢冷凝器的燃气热水器,通过与原有的普通强排恒温燃气热水器在不同燃烧工况下的烟气排放规律,压力变化规律等对比实验,以分析在普通强排恒温机上增加不锈钢冷凝器的可行性。
