Development Of Absorption Cooling System Work By Using Solar Energy


This paper is devoted to optimize the performance of absorption cooling system working with on solar energy .It aims at reducing the cost of the absorption cooling system and reducing the temperature of the generator to enable the cooler to work with solar collector more economical and to reduce the energy consumption compared with classical cooling system.The COP has been studied for four absorption systems which using water and lithium- Bromide. The temperature of the generator for each cycle was determined according to the (pressure – temperature –concentration) diagram. The COP has been determined by drawing it’s the change with the change of temperature of the generator after determination of condensation and evaporation temperature. The results of this work indicated that, the COP. for double effect cycle is high respectively, but it requires expensive solar receivers.
