Abstract

Adsorption cooling systems have good energy saving potential in buildings and are environmentally benign. This study aims at improving the performance of a waste heat driven adsorption chiller by applying a novel composite adsorbent which is synthesized from mesoporous activated carbon impregnated by soaking in Sodium Silicate solution and then in Calcium Chloride solution. Modeling was performed to analyze the influence of hot water inlet temperature, cooling water inlet temperature and adsorption/desorption cycle time on the specific cooling power (SCP) and coefficient of performance (COP) of the chiller system with the composite adsorbent. The simulation calculation indicates that the COP value is 0.65 with a driving source temperature at 85°C in combination with coolant inlet and chilled water inlet temperature of 30°C and 14°C, respectively. The delivered chilled water temperature is about 9°C under these operating conditions, achieving an SCP of 380W/kg.
