An adsorption cooling system has been designed and built employing granular activated
carbon (GAC)eR134a as adsorbenterefrigerant pair. The performance of the system has
been determined using a cycle simulation computer program written in Fortran. The
performance of the system has been determined varying driving heat source inlet
temperatures and delivered evaporator temperatures. The maximum driving heat source
temperature is kept below 100 C to utilize solar thermal energy or waste heat sources. The
results showed good agreement between the theoretical and experimental data. The
maximum theoretical coefficient of performance (COP) is obtained as 0.35. The experimental
specific cooling energy (SCE) is reached up to 70 kJ kg1 whereas the maximum
theoretical SCE of the system is 83 kJ kg1. The pressurized-bed adsorption cooling system
can effectively utilize low grade waste heat of temperature below 100 C.
