This paper presents an innovative system for solar thermal process steam and chilled water production. The system consists of a 2-stage solar thermally driven steam jet ejector chiller with latent heat and cold storage driven by motive steam from evacuated tube collectors with compound-parabolic-concentrator (CPC-collectors). Within this paper the design and the functionality of the demonstration plant and essential aspects of the system control are discussed. In addition, operational experiences, the operational behaviour of the entire system as well as performance figures are presented and evaluated.
