5. Solar cooling - A demonstration model for the classroom

For the project partners from Mediterranean lands it was of great importance to determine the extent to which solar energy is practical for cooling, and what knowledge is necessary for such a technology. It was very quickly determined through a market analysis, that the solar cooling area was still at a very early stage from the commercial point of view. Apart from a few pilot projects, there is little other experience of note. Because plants (absorption and adsorption) in the small scale area for teaching purposes are not marketable, the idea was considered of constructing a model ourselves, which uses a small solar plant as an energy supply and an absorption refrigeration machine on the basis of gas refrigerators for cooling. In principle, the function method of absorption refrigeration machines will be demonstrated according to the following pattern:
