خلاصه مقاله:

A thermodynamic model has been used to evaluate the coefficient of performance of a pump-less LiBr-Water absorption cycle. Here the bubble pump is used to circulate the solution between generator and absorber. Parametric study of bubble pump showed that 25 mm diameter of lift pipe is suitable to circulation of solution. This pipe with 600 W bubble pump heat input can me achieve about 2700 W cooling capacity with COP around 0.46. To achieve more refrigeration capacity (5-10) A number of parallel bubble pumps are required.
