| Abstract | ||
| The results of our research work point to the possibility of introducing a new source of energy added to the other sources of renewable energy prevailing in Yemen. That is the energy of the cold waters at the depth of the sea (Exergy of cold water) in the Yemeni region of which the temperature reaches 2.6 oC at 2400 m deep. Three maps were identified and put for some astronomical sites of Yemeni regional waters of Aden gulf for the objective of their study. The physicothermal data relating to water surface up to 2400 m deep were studied and analyzed in order to define the sort of cooling media which can be used in the technology of this energy source. For that purpose, the gases of Freon were chosen: R40, R142a, R22, R12, Cl2 and the sea cold water depths H2OSCW. The study of the physical, therodynemical, hydrocrystalline and gaseous properties of these media make us able to put a suggestion for three individual systems working by the closed physico-thermal circle and combined with the temperature of the deep sea waters for each working medium. These suggested systems are as the following: The first system for air conditioning is working on the gaseous hydrocrysalline method and uses the media of Cl2, R40, RI42a, R22, and R12. The second system for air conditioning is working on the all water system and uses the medium H2OSCW.The third system is working on the gaseous hydrocrystalline method of sea water desalination and uses the media of Cl2, R40, R142a, R22 , R12. Depending on the mentioned above, we conclude that the second system is the least energy consumption and environmentally pure due to its direct use of the cold sea waters as a cooling medium. | ||
