For the specific climate condition, An experimental setup is designed and built to study ejector refrigeration system performance using HFC134a as working fluid in this paper. The experimental data demonstrate that the hourly COP and cooling capacity of the system vary with the solar radiation and the ambient temperature; in addition, the time-averaged COP of the system at the specific climate condition...
In order to enhance the ejector performance, a model for the solar ejection refrigeration system used R134a as refrigerant has been established in this paper. The relationship between the ejector critical back pressure and the system working condition has been discussed. It is found that the critical back pressure increases with the evaporation and generation temperature. The critical entrainment...
An experimental ejector refrigerant system is designed and constructed to study the performance of HFC134a as working fluid in this paper. The influence of evaporator, generator, and condenser temperatures on the system performance is studied. The experimental results demonstrate that the entrainment ratio, cooling capacity, and COP of the system increase with increasing of the evaporator temperature,...
