Designing a climate-friendly and economic cooling system by TED Istanbul College Foundation Private High School, Turkey
The Turkish team designed a climate-friendly, renewable and economic cooling system which does not harm the natural resources. In their research they used ceramic and zeolite together: Transpiration cooling is provided by the ceramic stones; the heat input and output characteristics of the adsorption/desorption mechanism of zeolite provides cooling.
The team found out that the designed system creates a synergic effect as a result of the combination of the transpiration cooling and the adsorption/desorption mechanisms of water vapour in the cages in zeolite crystals. First, the water in zeolite evaporates and dries the surface in the system. The water in ceramic stones evaporates later since it is in the lower part. Then, it is adsorbed by the dry surfaces and causes heat increase. However, this heat makes the water in ceramic stones evaporate and cools the area during evaporation.
