广西太阳能热水应用项目能效测评与节能量分析

Energy efficiency evaluation and energy saving analysis of solar hot water projects in Guangxi

对广西地区6个城市的62个应用太阳能热水系统的项目进行了能效测评,分析了不同城市、不同建筑类型、不同系统形式、不同集热器类型热水系统的节能减排量与经济效益,得出了节能量与集热器面积之间的关系。结果表明:广西地区应用太阳能热水系统有良好的节能减排效果,并且集热器面积越大,节能效果越明显,集中式太阳能热水系统节能效果最好。

Evaluates the energy efficiency of solar hot water systems applied to 62projects in 6cities of Guangxi.Analyses the energy saving,emission reduction and economic benefit under the conditions of different cities,different buildings,different systems and different heat collectors.Obtains the relationship between energy saving and collector area.The result shows that there are good energy saving and emission reduction effects.The larger the collector area,the better the effect of energy saving.Moreover,the effect of the centralized solar hot water system is the best.
