摘要:冷却塔是空调系统的重要组成部分,其运行方案会对系统运行能耗造成明显影响。过去的研究缺乏不同冷却塔运行方案长周期能耗分析和考虑地铁车站空调负荷与地上建筑差异性的针对性研究。选取厦门地铁典型车站,结合现场实测数据,建立了全年逐时能耗分析模型。模型的长期预测数据与实际能耗数据的对比验证结果表明:模型预测精度满足分析要求,计算误差为5.09%。利用分析模型对3种常见冷却塔运行方案的运行能耗进行了分析,得到了不同方案典型时刻及制冷季长周期的节能潜力。综合成本和效益,厦门地铁典型车站宜采用冷却塔台数灵活控制方案,冷却塔变频运行方案的经济性一般。

Abstract: The cooling tower is an important part of the air conditioning system, and its operation scheme has a significant impact on the system operation energy consumption. Past researches lack long-term energy consumption analysis of different cooling tower operation modes and targeted studies considering the difference between the air conditioning load of underground railway stations and the above-ground buildings. This paper selects typical underground railway stations of Xiamen and establishes an analysis model of hourly energy consumption throughout the year based on field measured data. The long-term prediction results of the model are compared and verified by the actual energy consumption data. The calculation error is 5.09%. The prediction accuracy of the model meets the analysis requirements. The energy consumption of three common cooling tower operation schemes is analysed using the analysis model to obtain the energy saving potential of different scenarios at typical moments and a long period of the cooling season. In terms of comprehensive cost and benefit, the typical Xiamen underground railway stations should adopt a flexible number control scheme of cooling towers, and the cooling tower frequency conversion scheme is not economical.
