TTK7D-6.0型 | TTK7D-6.0 Model

TTK7D-6.0型司机室空调机组是专为HXD1B、HXD1C型和谐号电力机车设计的产品。该司机室空调系统具有通风、制冷、制暖等功能，通过回风温度和环境温度传感器实现自动控制，设置手动控制功能，可以为机车司机室提供舒适的室内环境。空调机组安装在司机室内的操纵台下，机组的回风口在靠近室内的端面，新风进口在机组底面，新风和回风在机腔内混合后，经空调冷却(或加热)，再通过送风机，向上送入司机室内，使得室内的温度逐渐调节，并使其维持在较舒适的范围内。空调机组的冷凝水通过机组底部的排水孔，直接排至车底。空调机组的室外冷凝风从机组前端进入，通过冷凝器后，再从机组底部向车下排出。空调机组采用PLC控制模式，电气部件位于靠近室内的端面，对空调进行可靠的控制、保护和故障诊断。电气部件通过连接器与操纵台上的控制面板相连，可方便的进行操作及检修。
