Abstract

The investigation showed that there were few researches about the real dynamic performance of solar assisted liquid desiccant air conditioning system with the unsteady term in the governing equations. Regarding the unsteady properties of the components, a novel dynamic model was developed for a solar assisted internally-cooled liquid desiccant air conditioning system. In the model, the variable t (time) was involved in the governing equations of each component to take into consideration the influence of the previous condition on the following state of the system. The accuracy of the above mathematical model was verified partly with experimental results of some key components. Then, the model was applied to a real solar assisted internally-cooled liquid desiccant air conditioning system for an office building with the capacity of eight people in Hong Kong. The transient performance of the system on the summer design day of Hong Kong was investigated. The results reflected the necessity of considering the influence of the former state on the following running of the system. To sum up, the novel model could be a reliable tool to predicate the system operation and provide useful information for better control of the system as well.
