摘要：提出了一种适用于北方地区的太阳能耦合空气源-水源热泵复合供暖系统。以某铁路站区为例，建立了TRNSYS仿真模型和优化模型，分析了该系统的性能，获得了不同保证率下的设备容量和运行特性。结果表明，该组合供暖系统供水温度高且稳定，平均供水温度达60℃,对室外环境和供暖末端适应性强；该系统能最大限度地利用太阳能，提高太阳能利用率，相比无太阳能的空气源-水源热泵复叠供暖系统，系统综合能效提升了22.5%～117.8%,平均提升了67.96%。研究结果为北方严寒、寒冷地区铁路站房提供了一种可行的供暖方案。

Performance analysis of a solar energy coupled air-source and water-source heat pump composite heating system
Abstract: This paper proposes a solar energy coupled air-source and water-source heat pump composite heating system which is suitable for Northern China. Taking a railway station area as an example, the TRNSYS simulation model and optimization model are established to analyse the performance of the system, and the equipment capacity and operation characteristics under different guarantee rates are obtained. The results show that the combined heating system has a high and stable water supply temperature, the average water supply temperature reaches 60 ℃, and it has strong adaptability to outdoor environments and heating ends. The system can maximize the use of solar energy and improve the utilization rate of solar energy. Compared with the air-source and water-source heat pump superposition heating system without solar energy, the comprehensive energy efficiency of the system has been improved by 22.5%-117.8%, with an average increase of 67.96%. The research results provide a feasible heating scheme for railway houses in severe cold and cold zones in the north.
