摘　　要：为研究用于数据中心的动力型热管系统性能,本文在焓差法实验室对三类压缩机性能进行了实验研究,结果表明:1)带气泵功能的压缩机具备低压缩比运行能力,可根据室外环境温度以及室内负荷不同分别切换不同工作模式,简化系统配置,具有很好节能效益,其中变频转子压缩机COP可以超过20,变频涡旋压缩机COP接近20,可以较好的替代液泵;2)中小型机房空调领域,综合利用气相动力型热管与压缩制冷技术,拓宽了自然冷却利用时间,全年能效比AEER远高于常规机房空调,配合运用地域性风冷、水冷、蒸发冷等节能方式,为现代数据中心节能减排提供了新的思路;3)大型数据中心空调领域,磁悬浮压缩机COP超过20,具有较高的节能效益,但与液泵相比仍具有一定差距,同时离心式压缩机作为气泵运用存在循环不畅的现象,需要液泵进行压头补偿。In order to get better performance of power-assisted heat pipe systems,the performance of three types of compressors was experimentally studied.The results show that:1)a compressor with gas pump function has the function of a low compression ratio operation,which can switch between different modes,according to different outdoor temperatures and indoor loads,and simplify the system configuration.Additionally,it has good energy-saving benefits.The coefficient of performance(COP)of the inverter rotor compressor can exceed 20,the COP of the inverter scroll compressor is close to 20,which shows that they can be a good alternative to the liquid pump;2)for the air-conditioning systems in small data rooms,comprehensive utilization of the gas heat pipe and compression refrigeration technology broaden the utilization time of free cooling.The annual energy efficiency ratio(AEER)is considerably higher than that of the conventional computer room air conditioning.The application of regional energy saving methods such as air cooling,water cooling,and evaporative cooling provide a new strategy for energy saving and emission reduction of modern data centers;3)for air-conditioning in large data centers,the COP of magnetic bearing compressors exceeds 20,and results in higher energy-saving benefits.However,there is still a certain gap as compared with the liquid pump.At the same time,centrifugal compressors used as gas pumps have a shortage of circulation,which requires the liquid pump to compensate the pressure head.
