This study proposes a refrigeration cycle operating on a compression-absorption cycle. This instalation can improve the performance of an absorption refrigeration machine energy consuming low exergy value. This installation uses the NH
-NaSCN as refrigerant. In addition this cycle is working at three pressure levels, the absorber is operated at an intermediate pressure (Pint) between the pressures, P
, for temperatures of evaporation and condensation, respectively (-10°C, 40°C). The machine operates at a temperature of generator T
= 53 ° C and presents a COP of 0.60. For the same conditions the single stage machine presents a COP of not more than 0.55 at a generator temperature of 140 ° C.
