Résumé

Results of performance measurement of a small cooling capacity laboratory model of an adsorption refrigeration system for thermal management of electronics are compiled. This adsorption cooler was built with activated carbon as the adsorbent and HFC 134a as the refrigerant to produce a cooling capacity under 5W using waste heat up to 90 °C. The thermal compression process is obtained from an ensemble of four solid sorption compressors. Parametric study was conducted with cycle times of 16 and 20 min, heat source temperatures from 73 to 87 °C and cooling loads from 3 to 4.9 W. Overall system performance is analyzed using two indicators, namely, cooling effectiveness and normalized exergetic efficiency. [Reprinted with permission from Elsevier. Copyright, 2011].
