Abstract:
The objective of this thesis is to design and simulate Intermittent solar adsorption refrigeration machine. A solar heated charcoal / methanol of refrigeration machines as small unit of solar freezer on adsorption principle is used. The unit has a product capacity of about 5kg of ice daily. A flat-plate solar collector of (1𝑚2) area, and a water-cooled condenser of natural convection type is used. The evaporator was a flooded type evaporator, attached to the ice box to form a fully insulated unit. The machine was designed to work as intermittently; the night pe-riod is the productive period; while day period is the generative period. This type of machines has a great need in the society, especially in the rural areas, for general cooling purposes and in health centers for vac-cines saving and others. The research satisfied its objectives and that it shall continue to the stage of constructing this machine in commercial amounts for the benefit or need of our society. Further development and optimization of the system design is still required to improve coefficient of performance (COP).
