Analysis of Pressure Losses in the Cross Flow Fan Heat Exchanger at Various Thermal and Flow Conditions
Languages of publication
In this paper the analysis of performance characteristics of a cross flow fan working as an element of the unit incorporating heat exchanger as well as performance characteristics of the unit are presented. These experimental results were basic for consideration of pressure losses arising as an effect of direct connection of a cross flow fan and a heat exchanger located in the charging zone of the fan as a resistance. Analysis of an influence of rotational speed variation as well as a medium temperature on aerodynamic characteristics of heat exchanger let to propose a method for the local pressure loss estimation.
