低地板有轨电车车辆空调机组  Low Floor Tram HVAC

KLD40Y变频空调机组  KLD40Y Inverter HVAC Unit

2016年在原70%低地板有轨电车空调样机上进行改造,增加轨道专用的日立变频器,用于对压缩机的变频调速。功率为11kW,变化范围在30到90Hz,能够实现对压缩机的无极调速。在实验过程中,制冷效果良好,温度变化更为平滑,舒适度更高。测试节能效果,比同等的定频机组节能约10%-15%

In 2016, improvement on 70% low floor tram HVAC sample was made. Rail type Hitachi inverter was used for frequency control of compressor.

This inverter already applied on many programs, with 11kW power, frequency range from 30~90Hz.It can realize step less speed regulation for compressor. In the test, the cooling performance was good, temperature changed smoothly, it's therefore more comfortable. The energy consumption is also 10~15% lower than fix frequency units.
