In this research, performance of adsorption desalination systems is investigated numerically and experimentally through number of techniques including the use of advanced adsorbent materials known as metal organic frameworks (MOFs), various cycle configurations and operating conditions. A Simulink model was developed to simulate the heat and mass transfer processes associated with the adsorption/desorption processes, evaporation of seawater and condensation of potable water. This model has been used to investigate a number of new adsorbents; "AQSOA-Z02", "Aluminum Fumarate", "CP0-27Ni" and "MIL-l 01 Cr" for the purposes of water desalination and cooling as a secondary output. Number of operating parameters have been investigated including; effect of condenser, evaporator and bed's heating secondary fluid temperatures as well as half cycle time. It was concluded that decreasing condenser temperature, enhances cycle performance, therefore, a new system configuration was developed that enables decreasing the condenser temperature by utilizing all or part of the cooling effect produced in the evaporator which resulted in 314% increase in water production than conventional cycle. Two experimental testing facilities were developed to investigate CP0-27Ni and Al-Fumarate which resulted in maximum daily water production (SDWP) of 22.8 and 25.3 m3 .tonne·'.day·' respectively, while the maximum SDWP reported experimentally for Silica-gel is 13.46 m3 .tonne·' .day·'.
