Effects of the Boundary Condition on the Performance of a Falling Film Dehumidifier of Solar Liquid Desiccants Air Conditioning System

Abstract:

In this paper, a two-dimensional mathematical model of simultaneous heat and mass transfer of vapor absorption process in a counter-flow dehumidifier is conducted. The governing equations with different boundary and interfacial conditions describing the dehumidifying process are established. The calcium chloride solution is applied as the desiccant. The dehumidifying process between falling liquid desiccant film and process air with first, second and third boundary conditions is analyzed and calculated, respectively. Temperature distribution of the process air and desiccant solution is presented. Outlet parameters of the dehumidifier for both the process air and the desiccant solution are obtained.
