摘　　要：为积极响应国家节能减排以及开发利用可再生清洁能源提高可再生能源应用水平的号召,对济南市某高校的公共浴室供热水系统进行了节能改造设计,设计了一种低碳排放的太阳能-污水源热泵-空气源热泵多能互补耦合运行的热水供应系统。通过TRNSYS软件对整个系统进行了仿真模拟。通过模拟数据从系统的供热水温度、集热器的有效集热量、集热效率、热泵机组的性能系数,系统耗电量等方面研究了系统的性能。通过计算改造前后两种系统的年标煤节省量分析了系统的节能性。通过静态投资回收期法对系统进行经济性分析。综合结果得出该系统可以有效替代原有的燃气锅炉供热水系统,经济性好且节能潜力巨大。In order to actively respond to the national call for energy conservation and emission reduction and the development and utilization of renewable clean energy to improve the application level of renewable energy,an energy-saving renovation design was carried out for the public bathroom hot water supply system of a university in Jinan,and a low-carbon emission system was designed.Solar-sewage source heat pump-air source heat pump multi-energy complementary coupled operation hot water supply system.And simulated the whole system through TRNSYS software.The feasibility of the system is proved by simulation data from the system's hot water temperature,the effective heat collection of the collector,the heat collection efficiency,the coefficient of performance of the heat pump unit,and the power consumption of the system.The energy-saving performance of the system is proved by calculating the annual standard coal savings of the two systems.The economy of the system is analyzed through the static investment payback period method.The comprehensive results show that the system can effectively replace the original gas-fired boiler hot water supply system,with good economy and huge energy-saving potential.
