Thermo-economic Analysis of Biomass-Powered Single Effect LiBr/H2O Absorption Refrigeration System

Abstract

This work presents thermo-economic performance analyses of the absorption refrigeration system (ARS) having a capacity of 1 TR. The present ARS uses different types of biomass (wheat straw, rice straw, and soybean stalk) and produces a cooling effect at a temperature of 8 °C. The thermo-economic optimum generator temperature about 93.5 °C is obtained for the present ARS. In addition, the coefficient of performance (COP) is obtained about 0.678. The break-even point for the ARS is calculated about 10.8 years using wheat straw biomass. Further, the break-even point and biomass consumption are found the maximum for soybean stalk due to its higher cost and lower calorific value compared to wheat straw biomass.
