摘要：This paper investigates the potential of applying an indirect
evaporative cooler for heat recovery in air conditioning systems in moderate
climates. The counter-flow indirect evaporative heat and mass exchanger is
compared with commonly used recuperation unit in terms of achieved energy.
The performance analysis of the indirect evaporative exchanger is carried out
with original ε-NTU-model considering condensation from treated air. It was
found that the indirect evaporative exchanger employed as a heat recovery
device, allows to obtain higher performance than conventional recuperator.
Additional energy savings potential is related with utilizing the potential of
water evaporation to pre-cool the outdoor air. It is also stated that there is
a high potential of reusing condensate that forms in product channels of the
indirect evaporative exchanger and in the vapour-compression unit and
delivering it to the working part of the indirect evaporative exchanger.
