Talk Title
A Novel Thermally Driven Air-conditioning System – Integrated Adsorption and Absorption System

Talk Abstract
 

Low grade thermal energy has received significant research attention in scientific communities due to energy crisis and environmental impact such as global warming. This paper proposed a novel integrated adsorption-absorption system to effectively convert low grade thermal energy (e.g. solar energy, low temperature waste thermal energy or geothermal energy) into useful cooling. The working pricinple and advance of the proposed system is first illustrated using a Dühring diagram. Then a mathematical model is developed to investigate thermal and inherent characteristics of the adsorption and absorption phenomena in the system. The system performance is studied using the mathematical model and compared with the conventional adsorption and absorption chiller system under different working conditions. The effect of key operating parameters such as cooling water temperature, cooling water flow rate, heat source temperature and hot water flow rate on the performance of the proposed system is further evaluated. The results revealed that the proposed system could provide much higher thermal energy conversion efficiency at low heat source temperatures. Its performance would not be significantly affected by the heat source temperature, which often happened in the conventional adsorption and absorption system. This technology opened a new research direction for thermal energy conversion and utilization.
