Saudi Researchers Develop Electricity-Free Cooling System Using Ammonium Nitrate
Saudi researchers from King Abdullah University of Science and Technology have developed a new cooling system called Nescod, which stands for No Electricity and Sustainable Cooling on Demand. This system utilizes ammonium nitrate, a compound commonly used in fertilizers, to absorb heat through endothermic dissolution when dissolved in water. The process results in a significant temperature drop, making it an effective alternative to traditional air conditioning. The system is particularly beneficial for regions with limited access to electricity, as it operates without the need for electrical power. The regeneration cycle of the system uses solar energy to evaporate water, allowing the ammonium nitrate to crystallize and be reused continuously.
