The absorption system is one of the most suitable types of system for air-conditioning use. In addition, it has the advantage of being able to be powered by solar energy. In hot climates this type of system requires a wet cooling tower which consumes a huge amount of water. In arid zones, where...

An analytical solution is presented to describe the performance of a straight convecting fin operating in an oscillating temperature environment. The solution involves the amplitude parameter, A, and the frequency parameter, B, in addition to the steady-state convection-conduction parameter, N....

The absorption system is one of the most suitable techniques for utilising solar energy for air-conditioning purposes. Although it uses solar energy directly with minimum conversion, it consumes considerable quantities of water for the cooling tower. This is a serious disadvantage where solar...

In developing countries and remote areas where an electric supply is not available, a thermo-electric refrigerator is often needed for food and medical drugs storage. Such a refrigerator, which requires a direct current supply is suitable for matching with a photo-voltaic collector (PV). A...
