THERMODYNAMIC ANALYSIS OF A SINGLE-EFFECT SYSTEM

Abstract

Compressor intake air cooling in Gas turbine power plants is considered to be very important and feasible requirement now-a-days. The methods for the compressor intake air cooling are evaporative cooling, vapour compression system, vapour absorption refrigeration system, hybrid system. In the present work, the focus is upon the thermodynamic analysis of Water/LiBr Vapour Absorption Refrigeration System. The analysis includes Energy and Second Law Analysis of the system. Three different subroutines formulation is given for the prediction of various temperature combinations of the components of the system. The analysis is drawn for a volumetric air flow rate of 86 cu.m/s required for a 30 MW Gas Turbine Power Plant. The Second Law Analysis show that in the total system, the maximum exergy destruction occurs in the evaporator assembly including evaporator, absorber and condenser. The exergy destruction in the total system increases with increase in condenser and absorber temper...
