SARM: Simulation of Absorption Refrigeration Machine
Main Article Content
Abstract
The purpose of this work is: - the design of a simulation program for a refrigeration system absorption (single and double stage), working with the binary couple NH3-H2O, called SARM 'Simulation of Absorption Refrigeration Machine', - the creation of a database containing the physical and thermodynamic properties for ammonia, water and their mixtures with different concentrations - computer-aided design of the two diagrams of Oldham thermodynamic (LogP, -1/T) and Merkel 
, whose range has been extended (for P: from 0.1 to 50 Bars - T: from 213.15 to 513.15 K) - to size various organs (mono and exchangers diphasic) of the installation. To validate the simulation program, the results were confronted in one hand, those of R. Kuzman, J.S Gallagher on the thermodynamic properties of the binary pair NH3-H2O, and secondly, to those obtained by the software ABSIM 'Modular Simulation of Absorption Systems', about the performance cycles absorption. In both cases the results are satisfactory.
