某高校既有供热系统节能改造案例分析
|
摘要
目前我国部分北方高校既有供热系统多为自备小型燃煤锅炉,均面临烟煤锅炉拆除改造的问题。本文以济南某高校集中供热系统节能改造为例,结合实际调研数据,利用复合热源热泵技术,建立分布式能源系统替代原有的燃煤锅炉房,运用合同能源管理模式对整个校区既有能源系统进行了经济性分析。结果表明:改造方案需投入约784.5万元,每年节省的运行费用约212.19万元,运用合同能源管理运行模式,投资回收期约3.5年。
At present, many northern universities in China are still using the self-provided small coal-fired boilers for heating, which are facing the demolition and transformation problem. This paper takes an university located in Jinan Shandong province as an example to investigate the performance of the energy-saving transformation system. According to the actual surveyed data and the multi-sources heat pump technologies,a distributed energy system is proposed to replace the existing coal-fired boiler heating system. The economic analysis is done for the transformation proposal under the mode of energy management contract(EMC). The results show that the initial investment of the transformation project is about 7.845 million yuan and the annual saving operating cost reaches about 2.1219 million yuan. The payback period of the retrofitted system in the mode of EMC is calculated to be 3.5 years.
