摘要
分析苏州市城市地下综合管廊余湿的来源和强度的逐日变化规律,其中余湿来源主要为新风和廊内暴露水体表面散湿,两者均在夏季达到最大。计算案例中以65%的相对湿度为控制目标,每1000 m^3体积的管廊空间在单位换气次数下的新风除湿负荷为9kg/h,每m^2水体暴露面积的除湿负荷为0.0825 kg/h。因此,控制廊内湿度应主要考虑通风系统除湿并尽量减少廊内暴露水面面积。
This papers analyze the daily variation of the source and intensity of residual humidity in the underground urban utility tunnel of Suzhou City.The main sources of residual humidity are fresh air and the surface evaporation of exposed water in the tunnel,both of which reach their maximum in summer.In the calculation case,65%relative humidity is used as the control target.The fresh air dehumidification load per 1000 m^3 volume of tunnel space per unit of air changes is 9kg/h,and the dehumidification load per m^2 of water exposed area is 0.0825 kg/h.Therefore,the humidity control in the corridor should mainly consider the dehumidification of the ventilation system and minimize the exposed water surface area in the corridor.
