Modeling and comparative analysis of chilled water air conditioning systems and indirect evaporative cooling air conditioning systems in data centers

 In order to compare the technical and economic characteristics of the chilled water air conditioning system and the indirect evaporative cooling air conditioning system, carries out the modeling and calculation. Comprehensively compares and analyses the application effect of the two air conditioning systems in the main typical cities in China. The results show that the chilled water air conditioning system can achieve higher energy saving rate under an optimized operation control strategy, and the indirect evaporative cooling technology should be preferentially promoted in mild areas and northern areas with high electricity prices.
