            摘要:

            结合广州地铁空调系统,分析了地铁空调的冷负荷特点,指出人员变化引起的发热量变化及相应的新风量变化是造成系统冷负荷变化的主要原因。提出一种新型基于温度湿度独立控制的冷水梯级利用空调系统,对比分析了新系统与常规系统应用于地铁空调的节能性。

            Abstract:

            Analyses the cooling load characteristics in Guangzhou metro station hall, and points out that the change of people number is the main reason that causing the corresponding cooling load and fresh air volume change. Puts forward a new chilled water graded use air conditioning system based on temperature and humidity independent control, and analyses the energy-saving of the new system compared with the traditional air conditioning system in metro station.
