Experimental and Numerical Analysis of Regenerative Indirect Evaporative Coolers
Regenerative indirect evaporative cooling (RIEC) systems are an interesting alternative to conventional air-cooling systems. In the present work, the main objective was to experimentally determine the performance of a RIEC air-cooling system under different inlet air conditions. Moreover, a mathematical RIEC model based on a modified ε-NTU numerical method was developed and validated. The experimental RIEC results showed a high cooling capacity, with dew point effectiveness values up to 0.91. The accuracy obtained of the mathematical model was more than acceptable. Therefore, it can be used properly to study the global behavior of a RIEC.
