Abstract A test platform for solar combined gas heating system was designed and established in Tianjin, control strategy for system operation was determined to meet domestic heating and hot water supply needs; basing on performance test, a series of evaluation indexes in energy saving, environmental protection and economic benefit for system operation were put forward; selecting 6 typical heating days in winter, the weight of each evaluation index in the series was analyzed by entropy weight method, it was found that, the index of renewable energy guarantee rate occupied the maximum weight, the indexes of static investment payback period and cost-benefit ratio occupied the minimum ones with the same weight ratio, finally a comprehensive evaluation method for system performance under different operating conditions was established. This study provided a comprehensive evaluation for system operation across meteorological states and operating conditions, so that making actual operation and testing data comparable and providing a reasonable evaluation scheme for the optimal configuration and operation of the system.

太阳能联合燃气供热系统性能评价

摘要 在天津设计并搭建了太阳能燃气联合供暖系统试验平台，确定了系统运行控制策略，满足生活供暖和热水供应需求；在性能测试的基础上，提出了系统运行在节能、环保、经济效益等方面的一系列评价指标；选取冬季6个典型采暖日，利用熵权法对系列中各评价指标的权重进行分析，发现可再生能源保障率指标、静态投资回收期和成本指标所占权重最大。 -效益比在相同重量比下占据最小，最终建立了不同工况下系统性能的综合评价方法。
