As part of the collaboration between the laboratory of electromechanical systems of ENIS and SENCOM, we are interested in the design and development of a solar refrigeration system. The work began with experimental characterisation of the operation of the absorption machine powered by electrical resistance. The temperature control of the various components of the absorption machine and of the cold room used is done using an Arduino board connected by the various thermocouples. The second step is the use of an aero-voltaic system to supply the boiler of the absorption machine with hot air. This required the development of an adequate ventilation system allowing the circulation of the air heated by the solar collector to the boiler. In this regard, an experimental study is developed to choose the appropriate parameters for the cooling of the cold room by adopting a new solution that uses both the thermal energy of the collector cooling and the electrical energy produced by the photovoltaic system to panels. The various solutions proposed within the framework of this graduation project use solar energy as a new source of energy to replace traditional energies.
