LoginProblems of heat and mass transfer optimization in the plate cross-flow heat exchangers, usedin air conditioning systems for energy recovery from exhaust air, are discussed. The mainpeculiarity of the investigated unit is the possibility of realization of heat transfer withinexhaust air canals in the dry heat exchange conditions or in the conditions of coupled heatand mass transfer with occurrence of vapour condensation on the whole or on a part of theheat exchange surface of the matrix in the form of dew or frost. The paper contains results ofcross-flow heat exchanger investigations, obtained on the basis of complex research by usingmodern methods of optimization. The influence of the main dimensionless factors, affectingthe efficiency of the cross-flow heat exchangers, has been investigated. The received resultsoffer scope for estimation of optimal operating condition range variations for heat exchangers,used in air conditioning systems for energy recovery.
