Advanced modular simulation of absorption systems.

Author(s) : GROSSMAN G., WILK M.

Type of article: Article, IJR article

Summary

A computer code has been developed for simulation of absorption systems at steady state in a flexible and modular form, making it possible to investigate various cycle configurations with different working fluids. When all the equations have been established, a mathematical solver routine is employed to solve them simultaneously. Property subroutines contained in a separate database serve to provide thermodynamic properties of the working fluids. The code is user-oriented who conveys to the computer an image of the cycle by specifying the different components and their interconnections. Based on this information, the programme calculates the temperature, flow rate, concentration, pressure and vapour fraction at each state point in the system and the heat duty at each unit, from which the COP may be determined. Simulation results are described for the following cycles: water-lithium bromide triple-effect, water-lithium chloride solar-powered open absorption, single-effect ammonia-water and ammonia-water generator-absorber exchange.
