The Effect of Refrigerants on Ozone layer and Global Warming

Abstract

This study has been carried out to determine the effect of refrigerants on ozone layer, global warming and resultant environmental effect. Also the efforts exerted from international community and the Republic of the Sudan to solve this problem. No dought that phenomena of the ozone depletion and global warming causes hazardous effects on human being. From the begging of this century this phenomena has not been contend to conferences and lecture rooms , but become a day to day question that must be solved by earth citizens. Because it threaten the existence of human life on earth. Causes of zone depletion and global warming phenomena are the bad uses to the natural resources, and the reduction of this phenomena will be implemented by reducing the emission of some gases to the atmosphere, like CO2 ,CH4, CFC . This research will concentrate on the refrigerants effect. Refer the program adopted by UN for the treatment of ozone depletion, which has been implemented in Sudan in conjunction with Sudan University of Science and Technology (Refrigeration and Air Conditioning workshop). Training courses have been carried out on the field of new alternative refrigerant which has zero effect on ozone layer, these alternative refrigerants has negative effect to global warming The result of this study , LPG has no effect on ozone layer and very small affection on global warming the experiment showed that , LPG give more cooling compared with (R-12, R-134a) and has low rate of power (about 10% less than R-12,R134) and has similar C.O.P. From the above mentioned, the future researches must concentrate on HC refrigerants to avoid hazard effect on ozone layer and solving G.W.P Problems, resulting from using old refrigerants, which has negative effect on ozone layer and global warming . Also attention must be given to the treatment adopting precautions, taken to save the world from disaster.
