A cooling system for air conditioning of buildings which comprises creating a cold medium by dissolving a salt in water, said salt being characterized by forming an endothermic solution, passing air through or over said cold solution to cool the air before introduction into said building, after the potential cooling effect is exhausted the salt is recovered by evaporation of the water from the solution with hot air, said hot air being at least partly heated by solar energy.
