摘要
目前在轨道交通设备用房的空调机组选型中往往采用舒适性空调机组,通过分析认为不应采用,应采用机房空调机组。比较了送风温度与露点温度,并研究了蒸发温度下降对机组的影响、冷水机组供水温度的选择。研究与结果表明显热比高的机房空调应采用机房空调机组,冷水机组供水温度应为10℃。
Comfort air conditioner is widely used in railway transit equipment rooms. In the writer's perspective, it is not a good choice. It should select special air conditioner. Comparising between the sending air temperature and the dew temperature, and research the effect of evaporation temperature to air conditioning unit ,the selection of water supply temperature of chilled water unit. Research conclusions prove that computer room with higher sensible heat rate should use special air conditioner, the temperature of chilled water supply should be 10℃.
