"The solar driven Steam Jet Ejector Chiller (SJEC) is a new device for solar airconditioning. Previously, solar SJEC have been only investigated theoretically by static models and practically by small test rigs. A demonstration plant or a first pilot plant does not exist so far, so that the operational behaviour of a solar SJEC has not been investigated in detail yet. But due to the fact that solar irradiation and cold demand are not constant the operational behaviour is very important for plant design and the controlling concept. This publication presents a model for a SJEC and the results of dynamic simulations. The proposed model allows creating and investigating different plant and controlling concepts by its structure in model components. After the validation of the model, simulations of a fictive solar SJEC with parabolic trough collectors are accomplished to analyse the dynamic operational behaviour of the plant."
