This paper presents a theoretical study of a dual-actuated cooling system with a parallel flow (lithium-water bromide). The objective of this study is to identify the effect of both the average pressure and the bottom pressure on the proposed system performance. This study was performed using two levels of medium pressure and two levels of low pressure, And selected for the temperature of the bottom condensation and absorption temperature, the obtained results showed that the increase in the average pressure level extends the range of operating temperatures, increases the quantity of cooling produced and the quantity of heat given but does not improve the proposed system performance coefficient, Zawmh cooling effect of the proposed double absorption is achieved by lifting the lower pressure level where it reached (COP = 1.6).
