Performance Study of Liquid Power Loop Heat Pipe Backplane Air Conditioning System for Data Centers

为了降低数据中心的能耗,同时改善数据中心的温度场,解决局部发热的问题,回路型热管背板空调正逐步应用于数据中心改造。对压缩机-液体动力型回路热管背板空调系统进行了测试,结合GB/T 19413—2010中全年能效比的概念,测出各个工况点下的制冷量和制冷总消耗功率,计算出全年能效比,并与相同制冷量的风冷压缩机-液体动力型回路热管列间空调做了对比试验。可以看出在满足数据中心冷负荷的条件下压缩机-液体动力型回路热管背板空调具有一定的优势。

To reduce the energy consumption of data centers and improve the air flow organization,as well as to solve the hotspot problem,loop type heat pipe backplate air conditioning is gradually being applied in data center renovation.This article tested the compressor-liquid power loop heat pipe backplate air condition system,combined with the concept of annual energy efficiency ratio in GB/T 19413—2010,measured the cooling capacity and total cooling power consumption at various operating points,calculated the annual energy efficiency ratio,and conducted comparative experiments with air-cooled compressor-liquid power loop heat pipe inter row air condition with the same cooling capacity.It can be seen that compressor-liquid power loop heat pipe backplate air conditioning has advantages under the condition of meeting the cooling load of the data center.
