| Abstract | ||
| This study presents a lumped parameter modeling for one-bed, condenser, and evaporator of adsorption cooling system that uses activated carbon (AC)/ethanol as working pair. Pressure profile and evaporator temperature of the adsorption/desorption bed are presented. The simulation results showed the effect of cooling water inlet temperature, chilled water inlet temperature, and hot water inlet temperature (regeneration temperature) on the Coefficient of Performance (COP) and Specific Cooling Power (SCP) of adsorption refrigeration system. It is found that the COP and SCP increase with decreasing the cooling water inlet temperature. The minimum evaporator temperature reaches about 7 oC at cooling water inlet temperature of 17 oC achieving a maximum COP and SCP of 0.33 and 340 W/kg, respectively under adsorption/desorption cycle time of 1050 s. Increasing in the chilled water temperature leads to an increasing in the COP and SCP. It is found that increasing hot water inlet temperature decreasing COP and increasing SCP of the system. | ||
