Optimized Analysis of Energy-saving Retrofitting for a Public Building in Northern China

目前我国煤炭资源短缺,且煤炭在燃烧过程中释放大量粉尘、CO2、NOX、SO2污染物,加剧了雾霾天气的形成,节能减排任务迫在眉睫。改造以节能减排为主要目标,提高可再生能源建筑利用效率与比例,将既有高能耗、高排放的、以传统能源为主的建筑供暖制冷系统改造成以地源热泵与太阳能等可再生能源系统为主、常规能源为辅的复合冷热源系统。改造后的能源系统运行效率将大幅提高,性能更加稳定、可靠,具有很高的经济效益与社会环境效益。

The task of energy conservation and emissions reduction is imminent, as the shortage of coal resources and lots of pollutions content dusts, CO2, NOXand SO2during combustion of coal which increase the formation of haze weather. The energy conservation and emission reduction, main purpose of this project, will be realized through improving the efficiency and ratio of renewable energy. The existing heating and cooling system, based on traditional energy technologies with high energy consumption and high emissions, will be replaced by a hybrid heating and cooling system based mainly on solar and geothermal heat pump system and supplemented by traditional system. With the retrofitting, the system efficiency will be highly improved and its operation will be more stable and reliable, namely the system will receive obvious environmental and economic benefits.
