Development and Analysis of Direct and Indirect Air Cooling under New Situation

At the present stage,air cooling technology has developed rapidly in China,which direct air cooling technology as the preferred application is particularly prevalent.This paper reassesses the overall economy of direct and indirect air cooling on the basis of the new situation of the rising price of coal,electricity,obtaining the result that the indirect air cooling is increasingly showing its superiority under the case of the rising running costs.And technology innovations in the air cooling technology in recent years in China are briefly introduced.
