Résumé

Environmental concerns force designers to find sustainable solutions for energy consuming air conditioning. Desiccant cooling is one such solution. The main focus of this research was cooling and dehumidifying using a wheel which contains a matrix of sorption material or desiccants that can adsorb vapour. To make the system operate continuously, adsorbed water vapour must be driven out of the desiccant material (regeneration) so that it can be dried sufficiently to adsorb water vapour in the next cycle. In combination with a heat exchanger to recover the regeneration heat and an adiabatic humidifier at the end of this process, cooled air can be obtained. In this report, heat and mass transfer in different components of sustainable air-handling systems are modelled. The theory is validated by experiments with test facilities. In general, the accuracy of the models shows to be acceptable for practical applications.
