Model of H2O/LiBr Absorption Machine Using Falling Films
Abstract
The study concerns the development of a 10kW solar powered Lithium Bromide absorption machine devoted to air conditioning of efficient buildings. This paper describes a numerical model of a new concept of absorption machine working with falling films exchangers. In addition to offer both a mass and heat exchange on a plate, this technology provides a cheaper, compact and sturdy machine. Thus the evolution of temperatures, concentrations and flow rates are studied along the plate. The effect of the temperature of heat- transfer fluids evolutions, the flow rates variations of falling film and the length of plate are investigated.
