Numerical study of the effectiveness of a vertical falling plate film absorber for an absorption chiller.

Author(s) : PERIER-MUZET M., STUTZ B.

Type of article: IJR article

Summary

This study investigates the impact of design and operating conditions on the performance of a falling film grooved plate absorbers integrated in a Lithium Bromide water absorption refrigeration machine. The performance of the component is described using two parameters: the mass efficiency and the absorbed vapour mass flow rate per unit plate width. The study implements a heat and mass transfer model validated with specific experimental data. The absorber effectiveness proposed by previous studies was generalized so that all absorbers’ operating conditions could be considered. A parametric study considering variation of solution Reynolds number is conducted. Based on these simulations, global and local transfers are discussed.
