随着国家节能减排政策的出台,新型能源的研发和能源的再生利用越来越被人们所重视。城市生活污水和工业废水以其流量稳定排放的同时也浪费了很多热能。利用污水的热量供热也越来越多被人们所利用。但污水的温度低,温差小,水质差的特点无形中损耗了电能及增加了一次投资的成本。对于供热企业,这种直观上的能源节约与运行和投资成本的比较也是决定污水源热泵在供热行业发展前景的重要依据。 With the promulgation of the national energy-saving and emission-reduction policies, the research and development of new energy sources and the recycling of energy are increasingly valued by people. Urban domestic sewage and industrial waste water are also discharged with a steady flow of waste while also wasting a lot of heat energy. The use of heat for sewage heating is also increasingly being used by people. However, the temperature of the sewage is low, the temperature difference is small, and the characteristics of poor water quality virtually eliminate electrical energy and increase the cost of an investment. For heating companies, this intuitive comparison of energy savings and operating and investment costs is also an important basis for determining the prospects for the development of sewage source heat pumps in the heating industry.
