Abstract
A vapor-absorption refrigeration (VAR) system. The VAR system includes a VAR section having a condenser, an absorber, an evaporator, a first desorber, a second desorber, a first heat exchanger, a second heat exchanger, at least four throttling valves, and at least two pumps. The VAR section heats a saline water feed stream using heat released from the absorber and the condenser, producing cooling effect. The VAR system includes a direct contact membrane distillation-absorber (DCMD-Abs) section receiving the hot saline water feed stream. The DCMD-Abs section comprises DCMD-Abs modules linked in series. Each DCMD-Abs module includes a saltwater feed compartment and a water compartment, and a membrane. Due to temperature difference between the saline water feed stream and cooling water stream, water vapors are produced by evaporation in the saltwater feed compartment and passes through the membrane to the water compartment to be condensed therein.
