CONTINUOUS ADSORPTION REFRIGERATION PERFORMANCE OF ACTIVATED CARBON–R134A PAIR FOR ICE-MAKING APPLICATION USING TRANSIENT CFD SIMULATION

Abstract

The new system and refrigerant were introduced in heat driven adsorption refrigeration system. Adsorption refrigerator’s capability to be operated by relatively low temperature heat source has drawn considerable attention. This system can be driven by utilizing waste heat and solar energy. Positive gauge operating pressure has been pursing R-134a as the most suitable refrigerant due to its saturated temperature on high pressure and other considerations including health factor, safety, and environment. The continuous system was designed to obtain higher cooling capacity. The optimization was conducted on temperature for each process undergoing in the reactor to approximate the highest possible COP (Coefficient of Performance). The cooling capacity of the system was estimated by transient simulation on CFD software. The cooling capacity acquired by employing CFD transient simulation is 18.36 W, whereas the highest possible COP which could be attained is 0.1047 for ice-making application.
