THERMODYNAMICS ANALYSIS OF THE VAPOUR ABSORPTION REFRIGERATION SYSTEM

Abstract

A thermodynamic analysis is carried out to study the single effect and double effect series absorption refrigeration technology. The objective of this work is to design a lithium bromide water (libr-H2O) absorption refrigerator having a capacity of 3.5 kW .Through the application of first law of the thermodynamics the calculations for the heat transfer area of each component is done for the single effect VARS. And the tube sizing and the number of tubes used in the absorber are calculated. The simulation has been made with the help of EES. The results of simulation are to study the effects of the various working parameters such as generator, evaporator, condenser temperatures; effectiveness of the solution heat exchanger on the COP .the outcome can be useful in the design and the performance enhancement of these absorption systems.
