太阳能与燃气热水器联合供热水系统在村镇中的应用

Application Study for Solar Energy and Gas Water Heaters Hot Water Supply System in Village Buildings in Shanghai Area

对上海地区村镇建筑目前采用的生活热水供应形式进行分析,采用调研与实际应用结合的方法进行研究。洗浴主要方式中太阳能热水器占了55.6%,燃气热水器和电热水器都约为30%,但很少采用复合式功能系统。结合用能形式与资源条件提出太阳能与燃气热水器联合供生活热水系统,对系统设计与控制方面提出了相应的措施,并对其技术和经济性进行分析。太阳能热水器和燃气热水器联合使用与单独采用燃气热水器相比节能率约为60%,节约运行费用约62%。

In the paper,village building energy status in Shanghai is researched and analyzed.Combined with energy consumption status,analyzing the feasibility for combined hot water supply system of solar and gas wa-ter heater.The main way of solar water heater shower accounted for 55.6%,gas water heaters,electric water heaters are at about 30%,but rarely used composite system.Combined with can form and resource conditions proposed combined with hot water supply system of solar energy and gas water heater,puts forward the corre-sponding measures to design and control system,and the technical and economic analysis.Solar water heater and a gas water heater combined and separate the gas water heater in the energy saving rate is about 60%,sav-ing operating costs about 62%.
