| Abstract: | In this paper, the typical cases of air treatment in air conditioning engineering are analyzed based on thenon - irreversible thermodynamic theory. A new mathematics model is presented to indicate the transport phenomena ofthe cases. The temperature distribution of air flow and water film, along the length of plate, are experimentally ob- tained and the other thermodynamic parameters are predicted by means of that results. The influences on the calculating precision of the cases are analyzed in the Lewis number range of 0.1~1.5 by numerical integral to the mathematical model. |
