Feasibility of hybrid air conditioning unit applied to data centers

According to the energy saving and challenges of date centers in China, expounds the characteristics of data center air conditioning systems and the energy saving measures from the aspects of the heat and mass transfer mechanism, the influence of meteorological parameters and indoor thermal environment requirements. Presents the characteristics of a new type of hybrid air conditioning unit，and analyses its economy. Illustrates two similar actual engineering cases, and it turns out to be feasible when the unit is applied to date centers.
