Following the experimental and numerical investigations of the Xi’an demonstration unit in Part I, Part II presents a parametric study on the proposed urban-scale SALSCS by using the validated numerical model. This study is aimed at understanding the influence of different variables on system performance, namely, the solar irradiation, ambient-air temperature and ground temperature at a 2-m depth as ambient parameters, and the inlet and outlet heights of the solar collector, collector width, tower width and tower height as geometric parameters. The effect of pressure drop across the filters on the system flow rate has been evaluated as well. The parameters that considerably influence the system performance have been identified.
