Abstract
ENGLISH ABSTRACT: In this report various mathematical models for the thermal evaluation of
evaporative coolers and condensers are presented. These models range from
the exact model based on the work by Poppe [84P01] to the simplified
logarithmic models based on the work of McAdams [54Mcl] and Mizushina
et al. [67MI1], [68MI1].
Various computer programs were written to perform rating and selection
calculations on cross-flow and counterflow evaporative coolers and
condensers.
Experimental tests were conducted on a cross-flow evaporative cooler to
determine the governing heat and mass transfer coefficients. The
experimentally determined coefficients were cqrrelated and these
correlations are compared to the existing correlations. The two-phase
pressure drop across the tube bundle was also measured and a correlation
for two-phase pressure drop across a tube bundle is presented.
