| Abstract | ||
| Due to the spreading of cooling equipments that works with old cooling fluids(Freon) in the community,and because of the bad effects of these (Freon)in case of their spreading on the Ozone layer and the thermal enclosure phenomenon.It was necessary to provide theoretical and practical studies and researches on data bases dealing with the field of possibility to replace this kind of cooling fluids with those that is safe on the Ozone layer and thermal enclosure phenomenon with the least possible costs.this research included a practical study to appreciate the performance of a small water cooler(0.5 liter/hour)which submitted to a number of parameters of design changes that were possible with the least of costs , this were included by replacing the old cooling fluid that has bad effect on the Ozone layer(R12)with one that is safe on the Ozone layer(R134a).In addition to assist the work by conducting several practical procedures on each change on the water cooling circulation in order to reach the most precise results. The temperature of the water that is supplied to the consumer was considered as well as temperature of the compressor as a criterion to appreciate the water cooler performance with recording all other changes that are possible to compare with in the results schedule. | ||
