摘要
城镇污水具有水量大、水温水质稳定以及冬暖夏凉的特点,是一种余热型低品位清洁能源。将其作为污水源热泵的冷热源可为城镇建筑物等提供区域供热或制冷,具有较好的经济效益和环境效益。对污水源热泵的分类、国内外发展现状及关键技术问题进行了阐述,并以上海为例估算了该技术的节能减排潜力。研究结果表明,污水源热泵是一种技术经济上可行并兼具环境效益的城市污水综合利用方法。
Municipal sewage has the characteristics of large water flow,stable water temperature and quality,and warm in winter and cool in summer,and is a kind of low-grade excess heat clean energy.As the cold and hot sources of sewage source heat pump,it can supply heating or make cooling for the municipal buildings,and has the better economic benefit and environmental benefit.This paper sets forth the classification,development status at home and abroad,and key technical issues of sewage source heat pump,and estimates the potential of energy conservation and emission reduction by the practices of Shanghai.The results show that the sewage source heat pump is a comprehensive utilization method of municipal sewage technically and economically with the environmental benefit.
