Building and Experimentation of Diffusion Absorption Refrigeration Machines

This paper presents an experimental investigation of a driven n-butane/ octane (C4H10/ C8H18) diffusion absorption cooling machine according to the cycle of Platen and Munters. For that purpose, we construct a prototype designed for air-conditioning applications. The cooling capacity of the constructed machine is 55 W. A clear description of the constructed prototype is given. These researchers have a final goal which is coupling these types of cooling machines with solar energy. In this paper, our major challenge is to design and choose the kind, the shape and dimensions of all components, which will afford a final and complete machine. In this experimental case, the value of COP reached was 0.3. Experimental results show that such refrigerator, simply fabricated, gives promising results and could be used for clean and safe use where there is a growing interest.
