Abstract: The objective of this project is to review and analyse a compression-absorption heat pump of 100 kW heating capacity to be operated at various parameters like absorber temperature varying in the range of 50-80C, desorber temperature varying from 30-40C and the compression ratios of 5 and 6 . The working fluid selected is the ammonia-water mixture. A computer program has been developed in the Engineering Equation Solver (EES) software to carry out a detailed first and second law analysis of the system and the various performance parameters like the coefficient of performance (COP), circulation ratio (CR), exergetic efficiency etc. are calculated. The mass, material and energy balance equations are written for all the components of the system. The thermodynamic state of each of the points within the cycle is calculated . A detailed picture of the system is provided by the results of exergy analysis. The exergy analysis emphasizes that both losses and irreversibility have an impact on s...
