--节能型空调  Energy Efficient A/C

通过采用变频控制技术、并联压缩机技术、热泵等技术而实现节能。

Variable frequency control, paralleled compressor and heat pump techniques are used to realize energy efficiency. 

变频技术：通过调节压缩机频率实现节能：压缩机自动适应负荷变化而变频运行，运行频率降低时能效比提高而节能的同时减小车厢内温度波动；节省空调负荷变化过程中压缩机频繁启停的能量耗损。

Variable frequency technique：Energy efficiency is achieved by regulating frequency of compressor. The compressor adapts to load variation automatically and runs at variable frequency. When operating frequency drops, energy efficiency ratio is improved to reduce temperature fluctuation in the cab while saving energy so that energy loss during frequent start/stop of compressor during A/C load variation can be saved. 

并联压缩机技术：利用外部管路将两台压缩机连结在一起而形成并联压缩机、并共用一套换热器，当空调负荷需求下降时停止1台压缩机的运行将使能效比得到很大提升而节能；同时实现多级能力调节而减少压缩机启停频次、同时减小车厢内温度波动。

Paralleled compressor technique：Two compressors are connected with external pipelines to form paralleled compressors that share the same heat exchangers. When A/C load demand drops, 1 compressor can be stopped to greatly improve energy efficiency ratio and save energy. Also, multi-grade capacity regulation is realized to reduce frequency of start/stop of compressor and temperature fluctuation in cab.

High Temperature Resistant, Weatherproof, Thin, Mute and Integrated A/C

耐高温空调  High Temperature Resistant A/C：

选用适应高温运行的制冷剂和压缩机，通过制冷系统各部件的合理设计，使空调机组适用于高温地区。

Refrigerant and compressor suitable for operation at high temperature are selected. A/C units apply to high temperature regions by designing all components in the cooling system properly. 

防风沙空调  Weatherproof A/C：

采用公司的自动排沙专利技术，利用冷凝腔底板适当的斜度、冷凝风机作用及车辆的振动，将进入冷凝腔的沙尘从机组冷凝腔两侧面适当设置的排沙孔排出空调机组外，在列车运行过程中被两侧的风吹走。

Our patented automatic dust-removing technology is adopted to remove dust entering condensation chamber of the A/C unit through dust holes appropriately located on both sides of the condensation chamber with the aid of the appropriately sloped bottom plate of the condensation chamber, the condensation fan and vibration of the vehicles, which will be blown away by wind whistling by both sides of the train during its operation.
