| 摘 要： | 机房设备具有发热量大、每个机柜发热量不同和个体机柜各个局部发热量不一致的特点。由于机房内不同发热量机柜摆放的不确定性,目前在用的机房空调不能满足降温要求。本文提出一种针对于个体机柜内部发热量不均进行点对点降温的机柜空调。通过试验研究可知,在一个机体上的多通路蒸发器,通过增加两个通路蒸发管长度,并与其它通路分开供液,可以实现非等温送风,且制冷系统具有较高的工作效率。另一种回气管路装有背压阀的系统虽能实现非等温送风,但制冷系统的效率较低。

| Abstract: | The equipments in the machine room have great calorie power.The calorie power of different cabinet and the different part of a cabinet are also different.The position of the cabinets with different caloricity is indefinite,as a result,the machine room air conditioning can not satisfy the cooling.A cabinet on inequitable internal heat to cool peer-to-peer was presented.Through the experiment study,for an evaporator with multi-channel,increase the length of the boiling tube and supply the refrigerant separate... |
