Abstract
In this article a theoretical study is presented for solar powered combined system comprising a LiBr-H sub(2)O absorption cooling machine and a multi effect distillator (MED). The MED is powered by the waste heat of the absorption machine which improves the overall gain and the thermodynamic characteristics significantly. Results are given for a typical design summer day in Jeddah, Saudi Arabia for a range of firing temperature 150-190 degree C with a storage temperature amplitude of 10-20 degree C over a daily working period of 12 hours. For a given cooling load of 100 ton refrigeration, the system can produce up to 40 m super(3) of fresh water at a specific collector area of 12.4 liters of H sub(2)O plus 0.03 TR per square meter. The overall COP sub(O) reaches 1.44 which is more than twice that of a conventional absorption machine at the same temperature levels.
