Following the experimental and numerical investigations on the Xi’an demonstration unit in Part I, this Part II paper presents a parametric study on the proposed urban-scale SALSCS by using the validated numerical model. This study is aimed to understand the influence of various ambient and geometric variables on system performance. Ambient parameters covered in this paper include solar irradiation, ambient-air temperature, and 2-m depth ground temperature, while geometric variables include inlet and outlet heights of solar collector, collector side length, tower side length and tower height. Effect of pressure drop across filters on system flow rate has been evaluated as well. Parameters with considerable influence on the system performance were identified.
