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.
