This article discusses the features of the processes of heat and mass transfer, taking into account the formation of the contact surface during the interaction of air and water droplets sprayed in the working space of the spray chamber. The results of numerical modeling of heat and mass transfer processes are presented, which made it possible to establish the conditions of liquid atomization that ensure the most efficient flow of heat and moisture exchange processes in the working space of the spray chamber.

Keywords: air handling unit, spray chamber, heat and mass transfer, diffusion model, efficiency, droop parameters, calculation model, numerical simulation
