  • Two-stage refrigeration system
    Patent number: 6516626
    Abstract: A two-stage refrigeration system includes an intermediate slurry tank for receiving and storing a refrigerant vapor and a slurry of solid sublimatable refrigerant particles in a liquid. The intermediate slurry tank has a first outlet for outflow of the slurry from the tank, a second outlet for outflow of the refrigerant vapor, a first inlet for receiving at least the liquid, and a second inlet for receiving the refrigerant. The refrigeration system also includes a compression system having a first low pressure inlet and second intermediate pressure inlet, and having a high pressure outlet. A conduit connects the second outlet of the intermediate slurry tank to the intermediate pressure inlet of the compression system so as to compress the vapor with less energy than would be needed to compress low pressure refrigerant vapor.
    Type: Grant

  • Refrigeration system
    Patent number: 5715702
    Abstract: A refrigeration system comprises a mixing tank for a slurry of solid particles in a liquid, said mixing tank having first and second inlets and an outlet. A sublimator has a bottom inlet, a top outlet and several internal paths connecting the inlet and the outlet, said internal paths having no descending parts. A first conduit connects the outlet of the mixing tank to the bottom inlet of the sublimator via a pump, there being no descending parts between the pump and the inlet of the sublimator. A separator has an inlet and top and bottom outlets. A second conduit connects the outlet of the sublimator to the inlet of the separator, the bottom outlet of the separator being connected to the first inlet of the mixing tank. A compressor has an inlet and an outlet, and conduits connect the top outlet of the mixing tank to the inlet of the compressor and the outlet of the compressor to the second inlet of the mixing tank.
