Abstract：
Briefly describes and contrasts the performance characteristics of several kinds of indirect evaporative coolers, and points out the main forms and the partition basis of the system. Emphatically presents the application of the tubular indirect-direct two-stage or three-stage evaporative cooling air conditioning system in such provincial regions as Xinjiang, Gansu and Shanxi, puts forward the problems encountered in actual operation, and proposes some concrete improvement measures.
