ABU DHABI, 7 SEP, 04 (WAM) -- The UAE is experimenting with a new technologyfor utilising the energy used for cooling.
The department of Water Resources and Studies at the Office of the PresidentHis Highness Sheikh Zayed bin Sultan Al Nahyan, has begun conducting experimentswith the new technology developed by Nawaf Suleiman, the inventor of theenergy conversion plant and many other inventions.
The department is conducting the experiments at the Al Musafah Area inAbu Dhabi.
Suleiman told +Khaleej Times+ that the technology can produce and recyclethe energy at the same time.
"Basically, it's a cooling system that can produce electrical, kineticor thermal energy. The technology can be used for cooling purposes likebuilding stores, factories and farms in order to produce the electricalenergy needed to run the system," he pointed out.
"The main application forms and uses of this new technology are as coolingsystems with multiple functions: cooling, freezing and generating theelectrical energy during the work process, which can be used in the housingsector and in different industries," he added.
According to Suleiman, the technology works by drawing energy fromthe expansion of gas and converting it into kinetic energy to produceelectrical energy. Using this new technology, energy will be availableon daily basis during the cooling process. Financial recourses are savedand environment is protected.
Speaking about the project, he explained that energy has several formslike thermal, kinetic and electrical energy, and energy can change itsform. For instance, thermal energy can be transformed into kinetic, fromkinetic into electrical, and from electrical into thermal etc.
"When electrical energy is transformed into kinetic energy and then transformedinto thermal energy (gas, liquid or solid), it will spread and scatterto the surrounding medium before being spread to the atmosphere. The sunsupplies the earth with this kind of natural energy. Electrical energycan be easily transformed into thermal energy, this can be basically doneby passing an electrical current through a high resistance medium. Thisis what happens in the conventional electrical heaters, cookers or ironingmachines," Suleiman explained.
He added that thermal energy can be transformed into electrical energy,by using the method of burning inflammable materials (oil, gas or dieselfuels). The electrical energy can be further used to operate motors, engines,turbines, etc.
However, to operate an air-conditioning unit, cooling system, or refrigerators,the energy is necessary to run the air-compressor, and the compressedgas becomes fluid as it's temperature increases, which will be lost throughthe condenser.
"The state of the compressed air/gas became liquid by passing throughthe expansion unit needs more temperature to evaporate, which causes atemperature exchange (cooling effect) in the expansion unit. The kineticenergy gained by the gas, during the compressing process (accumulatedfluid) cannot be retrieved, thus the efficiency of the cooling unit (coolingsystem) will be lower (energy lost)," he pointed out.
Scientists tried to design cooling units (systems), which are able atthe same time to produce energy, but they faced many problems like: thefriction, loss of energy and the inability of the gas to expand nearlyto the ideal state. Moreover, the prevailing sense of the second law ofthermodynamics is there in view, which states that 'it's impossible totransfer the energy, from lower to higher level, without spending work.' All these reasons caused the scientists to give up the dream of havinga system based on recycling energy, just like the non-stop running motors.
