摘要
通过对广州地铁某车站设备区的研究,分析全年逐时空调负荷计算和空调机组运行负荷的动态变化状况,得出地铁车站设备区空调实际负荷特性及机组冷冻水进、出水温差、设备区室内温度、室内焓值等各项性能参数的变化规律,并以此对地铁车站设备区通风空调负荷的常用工程设计及运行模式进行评估,对地铁设备区通风空调系统提出优化建议、改进措施以及可行和节能的系统运行方案。
Through in-depth analysis of MAS in the metro station, the thesis showed hourly cooling load calculation and annual dynamic changes of operation of air conditioning unit. It found out the variation rule of each specification index of MAS in metro equipment area including actual air conditioner cooling load, temperature difference between incoming and out-going and water flow in water cooling unit, indoor temperature in equipment area, indoor air enthalpy value, etc. Based on the analysis, the thesis provided reasonable improvement measure for ventilation air conditioning system in equipment area and feasible energy-saving method for whole system operation.
