This paper is focused on evaluation and comparison of air-air heat exchangers of plate type used for retrieving the heat from the waste air. The first part of this paper shows how it is possible to evaluate and compare each exchanger with another one. Process and procedure of numerical simulation is described in the main part. The procedure involves selecting an appropriate geometry of the exchanger, computational mesh generating, defining boundary conditions and the choice of a viscous flow model. Three geometrical types of heat transfer surface were compared in this work. Results of numerical simulations were compared with experimental measurement.
