The present research has as intention the theoretical and experimental study of a new intermittent refrigeration system ejector cycle characteristics, with use of waste heat. Initially, was doing a bibliographical survey about the vapor ejector refrigeration system technology. In the following stage was doing a simulation of the corresponding thermodynamic cycle, with preliminarily intention to evaluate the performance of the system for different refrigerants fluids. On the basis of the results of the simulation were selected the refrigerant fluid and developed an experimental group of benches of the refrigeration system considered, where pressure and temperature sensory had been inserted in strategical points of the refrigeration archetype and connected to a computerized data acquisition system for measure the refrigerant fluid properties in the thermodynamic cycle. The test results obtained show good agreement with the literatureapplication/pdfAcesso AbertoEjetorRejeitos térmicosRefrigeração por ejetorCiclo de refrigeração intermitenteEjectorWaste heatCooling ejectorRefrigeration cycle intermittentmasterThesisCNPQ::ENGENHARIAS::ENGENHARIA MECANICA
