Study of two-phase turbine engine for solar space cooling. Final report

OSTI ID:5940507
Detailed mathematical description of two promising Biphase refrigeration cycles were developed and programmed on the computer (all known first-order irreversibilities were accounted for). Extensive parameter sweeps were made to identify the most effective working-fluid combinations and to determine the sensitivity of cycle-performance levels. Finally the projected performance of the two cycles have been bracketed to show that the Biphase Systems do have higher potential COP's than the absorption units. A cycle configuration was established for a nominal 3-ton air cooled refrigeration system and the design prameters were determined from the computer code. A two-phase turbine as a prime mover for this system was designed to operate at a constant nominal shaft speed of 3600 rpm with supplementary power supplied by a synchronous AC motor. A series of fluid compatibility tests were run to weed out potential fluid combinations that are reactive.
