Abstract：
In order to explore the application of evaporative cooling air conditioning technologies in China, based on different extreme temperatures of direct and dew-point indirect evaporative cooling, and according to the evaporative cooling driving potential, the possibility of using evaporative cooling to reduce cooling demand and the required air conditioning cooling time, puts forward the cooling potential index of direct and dew-point indirect evaporation cooling systems and the time-consuming indicator of air conditioning required. Analyses the index parameters of typical weather years of 270 meteorological stations in China using the k-means clustering algorithm. Obtains the applicable area of evaporative cooling air conditioning technology in China and analyses the applicable characteristics, providing a theoretical basis for the promotion of evaporative cooling air conditioning system and the selection of the initial system form.
