What is Absim Absorption Simulation?




Absim (an acronym for ABsorption SIMulation) is a computer code for simulation of absorption systems in flexible and modular form. It may be applied to closed and/or open absorption cycles operating at steady state, as well as to vapor compression and other thermodynamic cycles.


Definition and description of Absim




Absorption systems are heat-driven devices that use a liquid absorbent to transfer heat from a low-temperature source to a high-temperature sink. They can be used for cooling, heating, refrigeration, or power generation applications. Absorption systems can have different cycle configurations (such as single-stage, double-stage, or triple-stage) and different working fluids (such as water-lithium bromide, ammonia-water, or carbon dioxide-water) depending on the desired performance and operating conditions.


Absim is a software tool that allows users to simulate absorption systems in a flexible and modular way. It is based on unit subroutines that contain the governing equations for the system's units/components (such as evaporator, condenser, absorber, desorber, etc.) and property subroutines that contain thermodynamic properties of the working fluids. The units are linked together by a main program that calls the unit subroutines according to the user's specifications to form the complete cycle. When all the equations for the entire cycle have been established, a mathematical solver routine is employed to solve them simultaneously.


Features and benefits of Absim




Absim has several features and benefits that make it a valuable tool for absorption simulation. Some of them are:


  • It has a user-friendly graphical user interface (GUI) that allows users to easily input data, select options, run simulations, and view results.



  • It has a large database of absorption fluids (31) and units/components (15) that can be used to compose almost any absorption cycle of interest.



  • It has an algorithm that automates the initial guess selection for the solver, which improves reliability and reduces manual user work.



  • It has a genetic global optimization feature that can help users find the optimal values of design parameters (such as heat exchanger areas, mass flow rates, pressures, etc.) that maximize or minimize an objective function (such as coefficient of performance, exergy efficiency, etc.).



  • It can generate various outputs such as tables, charts, diagrams, reports, etc. that can help users analyze and visualize the simulation results.



  • It can export and import data in various formats such as Excel, CSV, XML, etc. that can facilitate data exchange with other software tools.



Applications and examples of Absim




Absim can be used for various applications such as:


  • Designing new absorption systems Evaluating existing absorption systems



  • Optimizing absorption systems for improved performance and efficiency



  • Comparing different absorption systems and working fluids



  • Researching and developing new absorption systems and working fluids
