摘要 提出了一种应用热虹吸管进行二次换热的冷凝式燃气热水器,从燃烧、传热和结构设计等方面对系统进行了计算与分析,并给出了合理的设计方案.进行了投资成本及经济收益分析,表明该装置换热效率高、安全可靠、投资回收期短,冷凝式燃气热水器具有推广价值. A condensing gas-water heater, for which a secondary heat exchanger based on thermosyphon is used, is put forward. The calculation and analysis of this system is carried on in this article in terms of combustion, transmit heat and structure design ere, and a reasonable design proposal is given. The analysis from its investment cost and economic ben- efits is made, which shows that the system may retain the following advantages: high efficiency of heat transfer, safety and credibility, and short investment recovery period. It is believed that it has directive significance on the future market of condensing gas-water heater.
