How about the stability of precision air conditioning -

Computer room air conditioning devices can't be fixed actual work under a certain condition, in the use of environmental change or under the influence of other interfering factors, its operation condition will happen. If the refrigeration equipment can only work stable in a certain design condition, and under other conditions such as oscillation problem and difficult to work, such a device is not reliable in practical application. Therefore, we must ensure that the designed device can steadily work within the scope of the condition. In the process of refrigeration unit design, after completion of specific conditions of various calculation is needed off-design checking work. If the working condition of checking calculation. The designed device cannot meet the requirements of all conditions, you must correct the original design. Reduce engine heat consumed power, increasing the service efficiency of the power of the data center machine room, reduce data center PUE value, at present basically has the following several ways: 1, the cooling channels in the data center computer room construction, and configure the computer room dedicated precision air cooled air distribution. 2, in the data center room construction thermal channel, and configure the supply room dedicated precision air cooled air conditioning. 3, construction in the data center room dedicated precision air cooled air conditioning cold and hot air pipeline, to fully sealed forced cooling rack. 4, used in the data center room under the air supply room dedicated precision air cooled air conditioning and intelligent air supply cabinets, cold air in the room air cooling net pressure room directly into the cabinet. 5, in the data center room with large water-cooled equipment room air conditioning. 6, in the data center room construction special large water-cooled machine room air conditioner and chip cooling pipe, directly to IT equipment chip heat dissipation. 7, in the data center room by large computer room precision air cooled air conditioning + new fan 1:1 configuration, rational utilization of natural fresh air cold source.
