摘　　要：基于“双碳”背景及城镇污水冬暖夏凉、水温相对稳定、富含低品位热源的特点,以苏州地区为例,简要探讨了污水源热泵系统在长三角地区应用的可行性。结合污水源热泵系统的形式、原理、应用现状等,调研苏州地区多个污水处理厂再生水水质、水量、水温条件。实地调查苏州地区已运行的一污水厂综合楼污水再生水水源热泵系统的运行情况,夏季综合能效比约3.6,冬季综合能效比约3.1,系统高效节能;分析一能源站污水源热泵作为冷热源的方案,得出污水源热泵系统作为空调冷热源具有较大的节能减排潜力,在长三角地区应用前景广阔。Based on the background of"carbon peaking and carbon neutrality"and the characteristics of urban sewage that is warm in winter and cool in summer,relatively stable in water temperature and rich in low-grade heat sources,taking Suzhou as an example,this paper briefly discussed the feasibility of sewage source heat pump system in the Yangtze River Delta.Combined with the form,principle and application status of sewage source heat pump system,the quality,quantity and temperature conditions of reclaimed water from several sewage treatment plants in Suzhou were investigated.According to the field investigation of the operation of the sewage regenerative water source heat pump system in a sewage plant complex building in Suzhou,the comprehensive energy efficiency ratio in summer is about 3.6,and the comprehensive energy efficiency ratio in winter is about 3.1,and the system is efficient and energy-saving;by analyzing the scheme of sewage source heat pump as a cold and heat source in an energy station,it is concluded that the sewage source heat pump system as a cold and heat source of air conditioning has great potential for energy conservation and emission reduction,and has broad application prospects in the Yangtze River Delta.
