AEER and PUE of liquid pump driven heat pipe composite air-conditioning in data center

对数据中心用液泵驱动热管复合空调进行试验研究,结果表明:全变频液泵驱动热管复合空调可根据室外温度或室内负荷在同一个回路中切换运行模式,无控制死区;变频转子式压缩机-液泵驱动热管复合空调的AEER(北京)可达6.10,可实现PUE<1.30的目标;变频涡旋式压缩机-液泵驱动热管复合空调的AEER(北京)可达9.19,可实现PUE<1.25的目标;磁悬浮压缩机-液泵驱动热管复合空调的AEER(北京)可达10.27,可实现PUE<1.20的目标。液泵驱动热管复合空调具有较高的AEER,配合间接蒸发冷却/凝等技术手段,拓宽自然冷源利用温区,为数据中心节能减排提供了新的思路。

The liquid pump driven heat pipe composite air-conditioning system in data center is studied by test. The results show that the full inverter liquid pump dirven heat pipe composite air-conditioning can switch different modes according to different outdoor environment temperatures and indoor loads in the same loop, no dead zone control;the AEER(Beijing) of the liquid pump driven heat pipe composite air-conditioning prototype which is composed of inverter rotary compressor can reach 6.10, can realize the PUE less than 1.30;the AEER(Beijing) of the liquid pump driven heat pipe composite air-conditioning prototype which is composed of inverter scroll compressor can reach 9.19, can realize the PUE less than 1.25;the AEER(Beijing) of the liquid pump driven heat pipe composite air-conditioning prototype which is composed of maglev compressor can reach 10.27, can realize the PUE less than 1.20. The liquid pump driven heat pipe composite air-conditioning has high AEER, if combined with indirect evaporative cooling/condensation technology, it can broaden the utilization time of free cooling, which provides a new thinking for energy-saving and emission reduction of data center.
