      摘要:

      提出了一種適用于北方地區的太陽能耦合空氣源-水源熱泵復合供暖系統。以某鐵路站區為例,建立了TRNSYS仿真模型和優化模型,分析了該系統的性能,獲得了不同保證率下的設備容量和運行特性。結果表明,該組合供暖系統供水溫度高且穩定,平均供水溫度達60 ℃,對室外環境和供暖末端適應性強;該系統能最大限度地利用太陽能,提高太陽能利用率,相比無太陽能的空氣源-水源熱泵復疊供暖系統,系統綜合能效提升了22.5%~117.8%,平均提升了67.96%。研究結果為北方嚴寒、寒冷地區鐵路站房提供了一種可行的供暖方案。

      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.
