再热除湿在轨道交通车辆热泵空调上的应用研究

Application Research of Constant Temperature Dehumidification on Heat Pump Air Conditioning of Rail Transit Vehicles

该文将再热除湿应用在轨道交通车辆热泵空调机组上,并进行了试验验证。结果表明:制冷工况下,独立除湿模式下,空调机组的送风相对湿度均在60~70%的舒适区间,有良好的除湿效果;该模式在制热工况下不适用。

In this paper,the constant temperature dehumidification is applied to the heat pump air conditioning unit of rail transit vehicles,and the test is verified.The results show that under the cooling condition,in the independent dehumidification mode,the air supply unit's air supply relative humidity is in the comfort interval of 60~70%,and has good dehumidification effect;this mode is not applicable under heating conditions.
