用于地铁空调系统节能的全工况智能通风窗——“会呼吸”的屏蔽门
|
摘要
针对设置屏蔽门的地铁空调系统无法利用列车活塞风对车站进行自然通风及冷却的问题,开发出一种能够适应全年不同工况的新型智能通风窗。该通风窗根据屏蔽门两侧压力以及站内外空气焓值等参数,自动控制窗户的实时开闭状态,最大限度地利用活塞风降低地铁空调系统运行能耗。通过理论分析和计算论证了该设备在实际运用中的可行性并对其节能效果进行了定量评估。
Aiming at the problem that the subway air-conditioning system with screen door can not use the train piston wind to naturally ventilate and cool the station, a new intelligent ventilation window that can adapt to different working conditions in the whole year is developed. The ventilating window automatically controls the real-time opening and closing state of the window according to the pressure on both sides of the screen door and the air enthalpy value inside and outside the station, and maximizes the use of the piston wind to reduce the energy consumption of the subway air conditioning system. The paper demonstrates the feasibility of the equipment in practical application and quantitatively evaluates its energy saving effect through theoretical analysis and calculation.
