而若是夏季高温高湿天气，进入干燥机的空气中已含有很多水分，故而干燥机在夏天所需要的排气风机比寒冷冬季要多。

Also, on a hot humid summer day, the "dry" air coming into the drier to replace the wet air is already carrying a lot of water, therefore more exhaust will be required than on a cold dry winter day.

如果干燥机蒸发水分较多，就需要更多的排气风机。

If the drier is evaporating a lot of water, it will require more exhaust than if it evaporates little water.

分析了单机性能、理论叠加性能和实际总排气性能间的关系，对串联风机的参数选择和串联布置方案确定具有参考价值。

It has practical value to the parameter selections of fans in series and to the sureness of the scheme in the series arrangement.
