Exergy Based Performance Analysis of a Solid Adsorption Solar Refrigerator

Year 2014, Volume: 4 Issue: 2, 363 - 370, 01.06.2014

Abstract

The exergy based performance analysis of a solid adsorption solar refrigerator is presented. The analysis is based on an exergy balance applied to each component of the refrigeration machine, leading to a general exergy balance equation. The dead state temperature was chosen to coincide with the ambient temperature. Results reveal that maximum exergy destruction occurred in the collector/generator/adsorber during heat up and adsorbate desorption phases with a value of 3747.77 kJ. Values recorded in the condenser and evaporator were 10.51 and 20.11 kJ, respectively while the exergy efficiency was in the range of 0.0008 – 0.012. It was also found that the rate of exergy destruction reduced as soon as adsorbate generation commenced; indicating superior energy and exergy utilization during desorption phase. Thus use of adsorbent and adsorbate with the potential of very early commencement of desorption can significantly improve the exergetic efficiency of the system.
