随着城市的发展和能源需求的增长,污水的热能回收利用越来越受到关注,开发污水源热泵技术对建筑节能降耗具有重要意义。本文就污水源热泵系统的工作原理、特点等方面进行了介绍,阐述了国内外污水源热泵技术的开发利用历程与工程现状,分析了城市污水热能资源潜力以及污水源热泵技术的发展前景,指出利用污水与环境的温差获取热能具有十分巨大的能量资源前景,适宜的热源距离是污水源热泵开发利用的先决条件,开发污水源热泵系统,可以充分利用城市污水处理厂的二级出水或城市污水作为水源,通过合理利用出水的流量和温差为城市住宅供暖。基于我国能源与环境的现状,污水源热泵系统具有良好的市场前景,是一种值得推广的能源开发利用方式。
With the development of the city and the increase of energy demand, more and more attention has been paid to the heat recovery and utilization of sewage water. The development of sewage source heat pump technology is of great significance for building energy saving. In this paper, the working principle and characteristics of the sewage source heat pump system are introduced. The development and utilization of the sewage source heat pump technology at home and abroad are described. The potential of urban sewage heat resources and the development prospect of the sewage source heat pump technology are analyzed. Utilizing the temperature difference between the sewage and the environment to obtain the thermal energy has a tremendous prospect of energy resources. The suitable heat source distance is a prerequisite for the development and utilization of the sewage source heat pump. Developing a sewage source heat pump system can make full use of the secondary effluent of municipal sewage treatment plants or urban sewage As a source of water, urban residential heating is achieved through the rational use of effluent flow and temperature differences. Based on the current situation of China’s energy and environment, sewage source heat pump system has good market prospects, is a worthy of promotion of energy development and utilization.
