slugThermodynamic Analysis of Vapor Absorption Refrigeration System and Calculation of COP
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 2
Abstract
This paper provides an analytical study of absorption refrigeration technology. Through the application of the first and second laws of thermodynamics upper and lower limits for the coefficient of performance (COP) of absorption cooling cycles are derived. These upper and lower limits, besides being dependent on the environmental temperatures of components of the cycle, are also dependent on the thermodynamic properties of refrigerants, absorbents, and their mixtures. The objective of this work is to design a lithium bromide–water (LiBr-H2O) absorption refrigerator with a nominal capacity of 5.25 kW. The various stages of refrigeration system are presented including the design of the evaporator, absorber, solution heat exchanger, generator and condenser and finally COP is calculated.
