Numerical Simulation for Energy Analysis of Double Stage Vapour Absorption Refrigeration System: A Software Development Approach

The main aim of this work is to perform of numerical simulation for energy analysis of double stage vapour absorption refrigeration system: A software development approach. Software is also developed for predicting the energy analysis of the same. Software development is performed under the MATLAB Simulink environment. Under energy analysis, specific enthalpy is evaluated at every thermodynamic state of vapour absorption refrigeration cycles and heat transfer rate or heat load are also estimated for major components of vapour absorption refrigeration systems which are represented in tabular form. Comprehensive thermodynamic design data are also estimated and obtained under the energy analysis of vapour absorption refrigeration system. These thermodynamic design data can also be used in fixing operating setting for existing or future systems and maintain automatic control on optimum operation of the systems. First law performance parameters coefficient of performance is also calculated for different refrigerant operated vapour absorption refrigeration system. Systematic literature on MATLAB Simulink is presented in this work for software development. Developed software is very user friendly and it can be used by any non-technical person for estimating energy analysis of double stage water-lithium bromide operated vapour absorption refrigeration (VAR) system.
