Cooling applications with renewable energy powered resorption systems

The use of renewable energy in cooling applications plays a key role in solving the problems related to the energy. Among the thermal energy powered sorption cooling systems, thanks to its operational features, resorption cooling systems with ammonia-water solution has more technical and economic advantages than its alternatives. It will significantly enhance the benefits of the use of the resorption cooling system if the required thermal energy for the system is obtained from the renewable energy sources or the waste heat. Moreover, reduced maximum temperature of required heat, lower pressures adjustable by ammonia concentration and supply of cooling energy below 0 °C provide considerable advantages in residential and industrial cooling applications. Also, the cooling energy can be stored by the use of ice storage tanks and can be used for cooling when the renewable energy sources are insufficient to drive the resorption system. In this study, technical features of the resorption cooling systems were introduced and the system was compared with the other sorption cooling systems. The cooling applications and the results of the resorption cooling system were presented and the benefits of the renewable energy and waste heat powered systems were defined. The results showed that resorption cooling systems have similar COP values with the conventional absorption systems. Thus, they will have wide spread use in the future because of their advantages among its alternatives.
