Abstract:
This thesis is a study of a vapor ejection refrigerating machine. The study consists in developing a program allowing the sizing of the ejector taking into account the characteristic data of the three heat sources (the evaporator, the condenser and the boiler). The results obtained are validated by experimental work carried out as part of the “VERPUR” research project (between CanmetENERGY
and Hydro-Québec, Canada). Then, we developed a calculation program in simulation mode to know the limits of this refrigeration cycle and define the characteristics of each point in the ejector for a specific geometry. A study of the influence of the temperatures of the three energy sources on the overall efficiency of the ejector cycle after seeing the influence of the type of solar collector on this
efficiency is also carried out.
