• introduction:

The most widespread cooling systems are based on the mechanical compression of refrigerant vapours. The installation of such equipments in lonely areas, in particular in developing countries, often runs up against the non­availability of classical sources of energy. While in Developed countries, relying heavily on fossil energy, need to use more effectively renewable energy sources which are less harmful for the earth’s environment is growing and more according to Kyoto protocol. The conversion of solar energy to cooling energy by the thermodynamic way can be obtained by a three-heat-reservoir refrigerating system evolving between two sources and a heat sink. Here, the coincidence of the maximum cooling loads with the maximum availability of the solar radiation is of great interest in solar refrigeration [4],[6].

This paper is dealing with the development of a computational simulation of a cooling cycle powered with a flat solar collector working with a two-phase thermosiphon [1].
