Revisiting assessment of heat and mass transfer in contact apparatus for steam treatment of air

Abstract

Modified methods are proposed for determining the surface area of heat and mass transfer in the contact apparatus in the humidification, cooling, dehumidification of air with water, as well as dehumidification of air with solid drying agent, based on the number of transfer units. The number of transfer units is determined by the method of graphical integration using I-d-diagram of humid air to evaluate both heat and mass transfer process.
