Abstract :

A thermodynamic simulation of a charcoal heat driven absorption refrigeration cycle was carried out. The simulation was performed in order to investigate the performance of the cooler and the effect the generator temperature has over the coefficient of performance (COP) on a single absorption refrigeration system that uses charcoal heat energy as a primary source. A 10 kg of water was used as design load to cool from ambient temperature of 32oC to a desirable temperature of 10oC. The temperature of the evaporator is 10oC while the condenser temperature is 40oC. The high and low system pressures are 16 atm and 4 atm respectively. The refrigerant-absorbent mixture is Ammonia-water. The system requires two effective heating hours to generate the refrigeration needed by the cooler. It was found that as generator temperature increases, the performance decreases. The paper provides theoretical basis for designing a cooler with heat provided by burning charcoal in a stove.
