摘要

为了研究转轮式两级蒸发冷却空调机组在高湿度地区的运行情况

对一台3000 m3·h-1风量的转轮式热回收型间接-直接蒸发冷却空调机组进行测试。测试结果表明

当开启一次空气侧的转轮式间接蒸发冷却段和填料段

二次空气侧填料段水泵关闭时

机组的送风温度为23℃

其低于室外空气的露点温度24.5℃

机组总的平均温降为7.1℃

此时转轮式间接段的平均温降为6.9℃

平均冷却效率为76.9%

明显填料段几乎没有起降温作用

主导降温是转轮式间接段;而相对于干燥、中等湿度地区

在室外干球温度为32.1℃时

起主导降温作用的是一次空气侧填料段

降温的平均值达5.5℃;这说明间接、直接、间接-直接蒸发冷却均可作为辅助制冷方式应用于制冷冷却昂贵的地方。

Abstract

In order to study the operation of rotary two-stage evaporative cooling air conditioning unit in areas of high humidity

a 3000 m3·h-1 air volume rotary heat recovery-type indirect-direct evaporative cooling air conditioning unit was tested.When opened primary air side rotary indirect evaporative cooling section and filler segment

the pump of secondary air side filler segment was shut down

the supply air temperature of the unit was 23℃

which was lower than the outdoor air dew-point temperature of 24.5℃

the total average temperature drop of the unit was 7.1℃

the average temperature drop of the rotary indirect segment was 6.9℃

the average cooling efficiency of 76.9%

filler segment almost did not play a role in cooling

the dominant cooling rotary indirect segment.The contrast in a dry

moderate humidity areas

the average outdoor dry bulb temperature of 32.1℃

which played a major role in cooling air side filler segment

lower the average temperature up to 5.5℃.This showed whether the indirect

direct

or indirect-direct evaporative cooling could applied where refrigeration refrigeration cooling was expensive.
