We describe a finite difference solution for combined heat and mass transfer on vapor absorption into a laminar liquid film. Heat- and mass-transfer coefficients are determined by calculating temperature and concentration variations at the film. A modular computer program has been developed for absorption systems to simulate various cycle configurations. The influence of component temperatures and heat-exchanger effectiveness on cooling coefficients of performance and component heat-transfer rates has been investigated to define optimum operating conditions.
