  • Modified two-phase refrigeration cycle
    Patent number: 11859874
    Abstract: A modified two-phase refrigeration cycle compresses a working fluid, condenses the working fluid into a saturated or supercooled liquid, expands the saturated or supercooled liquid into a two-phase fluid, and evaporates the two-phase working fluid. The modified two-phase refrigeration cycle reduces irreversibilities imposed by conventional refrigeration cycles and extracts energy from the working fluid during the expansion process. For instance, a system that employs the modified two-phase refrigeration cycle includes a two-phase expander to reduce irreversibilities during an expansion process and extract energy. In some instances, the system includes a two-phase compressor to compress two-phase fluids for varying loads and environmental conditions of the system.
