摘要: 在分析热管技术以及变频多联技术的基础上,提出一种新热管型空调系统,并进行样机分析与实验,结果表明:新热管型空调系统直接输送制冷剂化解了水进入机房的风险,解决多次换热效率低下的问题,提高了蒸发温度,拓宽了自然冷却时间;可根据室外环境温度以及室内负荷不同切换多种运行模式,系统结构简单,可靠性高;充分利用自然冷源,发挥液相热管高COP、成本占比低的优势,全年能效AEER远高于常规机房空调;克服磁悬浮压缩机COP较低、低圧缩比能量调节差、多末端分液不均以及低压比工况压头不足问题,配合地域性风冷、水冷、蒸发冷等节能手段运用,为大型数据中心全年冷却提供新的思考与方向。

Abstract: On the basis of comprehensive analysis of heat pipe technology and inverter and VRF technology, A new heat pipe air condition system is proposed, The prototype experiment is carried out, the results shows: The new heat pipe air condition system directly conveys refrigerant into data room, which resolves the risk of water entering the data room, solves the problem of low efficiency of multiple heat transfer, improves the evaporation temperature of the system and expands the utilization time of free cooling; The new heat pipe air condition system can switch different operation modes according to outdoor temperature and indoor load,it has simple structure and high reliability; The new heat pipe air condition system makes full use of free cooling source, takes advantage of high COP and low cost of liquid heat pipe, The AEER is much higher than that of conventional Crac; The new heat pipe air condition system overcomes the shortage of low COP of magnetic suspension compressor, solves the problems of low pressure ratio energy regulation and non-uniformity of multi-terminal liquid separation, compensates insufficient pressure head at low pressure ratio, with the application of regional energy saving means such as air cooling, water cooling and evaporative cooling, it provides a new thinking and direction for cooling large data centers all year round.
