【摘要】 基于建筑物的热负荷、太阳能集热器、热泵循环和土壤-水池的传热分析,建立了太阳能辅助地表水源热泵(SA-SWHP)模型,模拟分析了设计参数对系统性能的影响。结果表明,土壤类型、水池容积和集热器面积对系统性能有显著的影响,而水池的深度对系统性能的影响较小。对比不同运行模式的结果说明,在非供热季节太阳能贮存对冬季供热有显著的影响。更多还原

【Abstract】 Based on the heat load of buildings, the solar collector, the thermodynamic cycle of the heat pump and the soil-pond water heat transfer, a model of the solar assisted surface water heat pump is proposed, and the effects of the design parameters on the performance of the system is investigated. The results show that the effects of soil type, the volume of the water pond and the area of the collector are significant, but that of the depth of water pond is slight. From the comparison of the different running modes, it is shown that the heat storage in the summer can significantly affect the performance of the system in the winter.更多还原
