摘　　要：分别对基于行间空调冷却方案和置顶空调冷却方案的40 ft集装箱式数据中心进行物理建模与仿真研究。与置顶空调冷却方案相比,行间空调冷却方案的可靠性高、冷量利用率高、温度场更加均匀、可冷却的单机柜功率密度高达14 kW,而置顶空调冷却方案可冷却的单机柜功率密度只有8 kW。从集装箱式数据中心的热工环境来看,行间空调冷却方案和置顶空调冷却方案的机柜进风温度均在ASHRAE推荐的温度范围内,气流组织均存在旁流现象(置顶空调冷却方案相对较小),置顶空调冷却方案的冷量有少许浪费。The physical modeling and simulation study on the 40 ft container data center are carried out based on the cooling solutions of in-row air-conditioning and roofmounted air-conditioning respectively.Compared with the cooling solution of roof-mounted air-conditioning,the cooling solution of in-row air-conditioning has high reliability,high cooling utilization,and more uniform temperature field.Besides,it supports power density for each cabinet up to 14 kW with the cooling solution of in-row air-conditioning,but the power density for each cabinet is only 8 kW with the cooling solution of roofmounted air-conditioning.As for the thermal environment of the DCIC(data center in container),the inlet air temperature of these two types of cooling solution meets ASHRAE recommend temperature range.The air distribution of these two types of cooling solution exists bypass flow,and the cooling solution of roof-mounted air-conditioning is less.The cooling solution of roof-mounted air-conditioning is with a little cooling waste.
