摘要
以南京典型公共建筑作为研究对象,以土壤源热泵系统与冷却塔复合运行模式优化为目标。针对南京地区公共建筑夏季负荷的特点,通过分析地下土壤温度和空气湿球温度对土壤源热泵系统和冷却塔散热系统性能的影响,得到了土壤源热泵与冷却塔复合运行的优化策略,并给出了优化策略运行模式下暖通空调机组的设计建议和节能潜力分析。
The research object is the typical public building in Nanjing. The objective is optimizing the composite operation model of earth source heat pump and the cooling tower. Based on characteristics of summer load in public building in Nanjing, the influence of soil temperature and wet bulb temperature on the properties of earth source heat pump system and the cooling tower heat-removal system was an- alyzed. The optimization strategy of earth source heat pump and the cooling tower composite operation was obtained. Design suggestions and energy-saving potential analysis of HVA C unit in the operation mode of optimization strategy were proposed.
