Résumé

Indirect evaporative cooling technology to produce cooling water (called IEC chiller) is proved to be most predicable with lower outlet temperature of cooling energy and lower transportation power consumption. There are different process structures of IEC chillers. However there are not good methods and principles to compare and choose different processes. In this paper, two typical IEC chillers with different process structures are compared, by field testing results, theoretical analysis and simulation analysis. Based on the field-testing analysis and theoretical analysis, the comparisons by simulation are carried out with the same NTU and the same cooling capacity. The comparison results are obtained, which changes with the size of NTU. The main reasons are discussed and the principle of choosing different processes are primarily obtained.
