Abstract：

Briefly presents the current situation of the domestic data center. Points out major existing problems, including lack of related standards, serious commercialization of the power usage effectiveness (PUE), high operating costs, low designing level, lack of professionals, poor performance of air conditioning equipment, high water consumption, and further optimization of combined cooling heating and power (CCHP) systems. These problems have widened the data center application gap between our country and the western countries, all of which should be paid attention to and should be solved with all efforts.
