The increase in the use of non-renewable energy sources and the strong dependence of the energy sector on these sources, encourage the study of applications that use renewable energy sources. In this scenario, there has been an increase in the number of jobs related to refrigeration systems that use other sources of energy in addition to electricity, such as absorption cooling systems, which can produce a cooling effect using mainly heat. residual or other sources such as solar thermal energy. This article presents the design of a cooling system that will operate with solar energy, using the principle of absorption with the ammonia-water working torque in continuous function, to contribute to a cold production alternative in food preservation.
