摘　　要：为解决通信机柜传统空调能耗高、机柜内气流组织紊乱、基带处理单元(BBU)温控效果不佳等问题,研发了通信机柜用空调热管一体化设备,采用热管冷却为主、蒸气压缩式空调为辅的温控系统及下送上回、高风速、内循环的气流形式。机组应用于郑州某通信基站,经实地测试后,结果表明,在过渡季高温工况下,运行模式1调控BBU平均工作温度为38.2℃,最大出风温度为46.5℃,在过渡季常规工况下,运行模式2调控BBU平均工作温度为29.5℃,最大出风温度为41.3℃,均满足相关标准的温控要求,保证BBU安全运行。与通信机柜传统空调相比,空调热管一体化设备在运行模式1和2下,压缩机运行比例分别为24.9%和0,节能率分别为57.3%和71.9%,电能利用率(PUE)分别为1.43和1.19,过渡季综合节能率为71.3%、PUE为1.20。To address the issues of the high-energy consumption of traditional air conditioners in communication cabinets,disordered airflow organization in cabinets,and poor temperature control effect of the baseband unit(BBU),this study integrates air-conditioning with heat pipes for communication cabinets using a temperature control system with heat pipe cooling as the primary cold source and vapor compression air conditioners as the supplementary cold source.Floor ventilation with air return from the ceiling is adopted with high wind speed and internal circulation.The unit was applied to a communication base station in Zhengzhou,and field testing results showed that under the short-term high-temperature condition during the transition season,the average working temperature of the BBU in operation mode 1 was 38.2℃,and the maximum outlet temperature was 46.5℃.Moreover,under the normal working conditions of the transition season,the average working temperature of the BBU regulated by operating mode 2 was 29.5℃,and the maximum air temperature was 41.3℃,which met the temperature control requirements of relevant standards and ensured the safe operation of BBU.Compared with those of the traditional air conditioner of the communication cabinet,the compressor operation ratio of the air-conditioning heat pipe integrated equipment in operation modes 1 and 2 was 24.9%and 0;the energy saving rate was 57.3%and 71.9%;the power usage efficiency(PUE)was 1.43 and 1.19,respectively.The comprehensive energy saving in the transition season was 71.3%,and the PUE was 1.20.
