Keywords:
heat exchanger of evaporation-and-condensation type, optimization of design characteristics, minimization of heat-exchanging surface.
Abstract
The paper is relevant to optimization of the performance of gas-to-gas heat exchangers based on vertical transversely finned heat-transferring elements of evaporation-and-condensation type. The correlations taking into account the regularities of heat transfer for estimation of optimal ratio of the lengths of evaporation and condensation zones, under which the heat-transfer system has the minimum transferring surface corresponding to the specified conditions, were obtained.
