【摘要】 为了解决热泵的能效比受气温变化影响较大的问题以及缓解弃风弃光电问题，文中以某供暖面积为10万平米的小镇为模板，从运行策略、设备选型和功率设计等方面设计了河水源热泵与蓄热电锅炉复合供暖系统.然后利用TRNSYS软件对五种不同热负荷配比方案进行能耗模拟，再采用费用年值法对不同方案从初投资、年运行费用、年维护费用三个方面进行了经济性分析，得出当热泵承担55%热负荷时，费用年值最低，为954.12万元，经济性最好.更多还原

【Abstract】 In order to solve the problem that the energy efficiency ratio of heat pumps is greatly affected by temperature changes and to alleviate the problem of abandoning wind and photovoltaics, this paper uses a small town with a heating area of 100,000 square meters as a template, from the operation strategy, equipment selection and power design, etc.On the one hand, a combined heating system with river water source heat pump and thermal storage electric boiler was designed.Then use TRNSYS software to simulate the energy consumption of five different heat load ratio schemes, and then use the cost annual value method to analyze the economic efficiency of the different schemes from three aspects: initial investment, annual operating costs, and annual maintenance costs.When the heat pump bears 55% of the heat load, the annual cost is the lowest, at 9.5412 million yuan, and the economy is the best.更多还原
