摘 要:本研究介绍了郑州地铁定频和变频空调机组试验列车配置情况,并对车辆定频和变频空调控制原理进行了阐述。空调系统是与车辆整车性能密切相关的重要部件,夏季能耗占比较大。因此,对比分析了夏季制冷月份定频空调和变频空调的能耗。结果表明:试验条件下,变频空调机组较定频空调机组更加节能,在7—8月节电率约为10%。

Abstract: This study introduces the configuration of test train of constant frequency and variable frequency air conditioning unit in Zhengzhou metro, and expounds the control principle of vehicle constant frequency and variable frequency air conditioning. Air conditioning system is an important component closely related to the performance of the whole vehicle, and its energy consumption accounts for a large proportion in summer. At the same time, the energy consumption of fixed frequency air conditioning and variable frequency air conditioning in summer refrigeration month is compared. The results show that under the test conditions, the variable frequency air conditioning unit saves energy compared with the constant frequency air conditioning unit, and the power saving rate is about 10% from July to August.

隨着郑州市经济的快速发展和国家中心城市建设步伐的加快,城市轨道交通建设力度不断加大。地铁电客车电能消耗主要由牵引和空调两个系统产生,其中空调系统能耗占车辆总能耗的20%~30%[1]。因此,研究地铁电客车空调系统的节能具有重大意义。
郑州地铁根据夏季城市气候特点和车辆运营实际情况,选定城郊线电客车作为定、变频空调能耗试验列车,变频机组安装在列车1单元,定频机组安装在列车2单元。为了准确研究城郊线电客车变频空调的节能性,本试验通过实测手段,利用空调控制柜中的电能表记录列车两种空调在相同运营工况下的单元能耗,结合电客车走行千米数进行对比分析,以期为后续新车采购时空调选型提供科学的依据。
1 定频和变频空调控制原理
1.1 定频控制原理
定频空调主要由空调控制器和空调机组组成。1台控制器控制一节车的2台空调机组,如图1所示。空调控制器由主控制器、断路器、接触器、马达保护器及中间继电器等控制器件组成。……
