Design of Thermodynamic Data of a Solar Powered Ammonia Water Vapour Absorption Refrigeration System with Storage Units using EES

The aim of this paper is to estimate of energy analysis of ammonia-water vapour absorption refrigeration (VAR) system using EES (Engineering Equation Solver) software. Engineering Equation Solver makes available many built-in thermo-physical properties mathematical relations useful for thermal systems. Systematic procedure is presented for predicting thermodynamic properties of ammonia-water. 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. Heat load in major components of absorption refrigeration system is compared with the past published work. 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. Literature of Engineer’s Equation Solver software is also presented in this work. This Engineer’s Equation Solver software is very user friendly and it can be used by any non-technical person for estimating coefficient of performance of any single stage vapour absorption refrigeration (VAR) system.
