摘　　要：搭建了高效利用室外环境空气冷能的分离式热管与蒸气压缩式复合机房空调系统实验台,对系统在热管工况和蒸气压缩式工况的性能进行了实验研究。结果表明:复合空调系统在热管工况下换热量随换热温差、高差、风量的增大而增大;当换热温差进风温差从11.6℃增加到17.4℃,换热量增加了14.4%;风量由2937.4m3/h增加到4196.3m3/h,换热量增加了5.4%;高差由1.1m增大到2.0m,换热量增加了8.3%;该系统的最佳制冷剂充注量为5.4kg。该系统在蒸气压缩式制冷工况下也具有良好的运行效果,且可实现两种模式的灵活切换,表明该复合空调系统是一种的高效可靠机房空调系统。An experimental apparatus of combined computer room air conditioning system by heat pipe and vapor compression was built up to use outdoor air cold efficiently. The experimental study on the performance of the combined air conditioning system at both the heat pipe condition and the vapor compression cooling condition was caried out. The experimental results indicate that the heat exchange capacity of combined air conditioning system increases with these increases of temperature difference of evaporator and condenser,level difference of evaporator and condense height and the air flow. The inlet air temperature of evaporator and condenser increases from 11. 6℃ to 17. 35℃,the heat exchange capacity grows 14. 39%. The airflow increases from2937. 4m3/ h to 4196. 3m3/ h,the heat exchange capacity grows 5. 44%. The heat exchanger height increases from 1. 08 m to 2m,the heat exchange capacity grows 8. 28%,the optimal amount of refrigerant charge is 5. 4kg. The performance of combined air conditioning system is very good under the vapor compression cooling condition,and the system can achieve flexible switch over between two conditions,which shows that the combined air conditioning system is an efficient and reliable computer room air conditioning system.
