Application Research on Sewage Source Heat Pump Technology in Urban Residential Heating

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 growth of energy demand, the heat recovery and utilization of waste water is getting more and more attention. The development of sewage source heat pump technology is important for building energy saving. This paper introduces the working principle and characteristics of sewage source heat pump system, describes the development and utilization process of sewage source heat pump technology and engineering situation in domestic and foreign countries, analyses the potential of urban sewage and the development prospect of sewage source heat pump technology, and points out that it has a great prospect of the energy resources through utilizing the temperature difference between the sewage water and the environment, the optimum heat source distance is the precondition of the development and utilization of sewage source heat pump, the development of sewage source heat pump system can fully utilize the secondary effl uent water or sewage from city sewage treatment plant as water source, through the rational use of water fl ow and temperature difference for urban residential heating. Based on the current situation of China＇s energy and environment, sewage source heat pump system has a good market prospect, is a kind of energy development and utilization method which worth promoting.
