摘要
在夏季,对转轮式热回收型间接-直接蒸发冷却空调样机中的转轮式间接蒸发冷却器性能进行了测试。测试中转轮式间接蒸发冷却器的二次空气采用了2种情况:一种是直接采用室内排风;另一种是经过填料式直接蒸发冷却器降温后的室内排风。对其效率、制冷量、被处理空气的温降进行了试验研究;综合测试结果表明:相比于第一种情况,转轮式热交换器在第二种情况下的制冷量和效率均有所增加;在测试的范围内温降最高可达13℃。
In order to get the running effect of rotary wheel indirect evaporative cooler in summer ,making a series of tests in the rotary wheel heat recovery type indirect-direct evaporative cooling air conditioning prototype ,characterized by its efficiency ,cool-ing capacity ,heat transfer coefficient;At the secondary air side of rotary wheel ,two measures were taken to eliminate heat ,namely （1）Traditional sensible heat elimination;（2）Exhaust air is handled by wet film,then passes through secondary air side .Compre-hensive test results show that：the cooling capacity and efficiency of heat exchanger increase under mode 2,compared to the first mode.Within the scope of the testing the temperature drop maximum is 13℃.
