Performance comparison of the advanced indirect evaporative air coolers

Analysis of the results allowed establishing appropriate operational parameters (i.e. airflow ratios and initial sections relative length) for the new heat exchangers. The novel units were compared with cross-flow M-Cycle heat and mass exchanger. The main conclusion is that proposed solutions are characterized by higher cooling efficiency than the cross-flow M-Cycle unit. Combined cross-regenerative counter flow heat and mass exchanger obtained highest overall performance.
