This document contains summaries of three projects: 1) A study of an optimum performance solar-assisted ejector cooling system, including a schematic design. 2) The design and implementation of a refrigeration system project involving a solar distillation system based on a multiple-effect diffusion type still. 3) A distillation system that combines solar collectors with a multiple-effect diffusion type still to distill seawater or sewage water. Diagrams are included to illustrate the concepts and designs.
