Abstract (EN): In this paper, the development of a TRNSYS model, for the simulation of a solar driven ejector cooling system with an integrated PCM cold storage is presented. The simulations were carried out with the aim of satisfying the cooling needs of a 140 m3 space during the summer season in Tunis, Tunisia. The system is composed of three main subsystems, which include: a solar loop, an ejector cycle and a PCM cold storage tank. The latter is connected to the air-conditioned space. The influence of applying cold storage on the system performance was investigated. It was found that the system COP increased compared to a system without cold storage. An optimal storage volume of 1000 l was identified resulting in the highest cooling COP and highest indoor comfort (95% of the time with a room temperature below 26°C). The maximum COP and solar thermal ratio (STR) were 0.193 and 0.097, respectively. © 2017 Author(s).
