Ice Slurry Thermal Energy Storage System
2010
A laboratory scale ice slurry thermal energy storage (TES) system for high power device cooling is demonstrated. The TES rate is greater than 60 kW in a 30 s discharge period. The primary water flow as the heat source with a designed flow rate of 1.44 kg/s (or greater) and a temperature of 20 to 30°C is cooled down to a desired temperature by the TES system. A coaxial coil heat exchanger (HX) is used for the ice slurry TES heat transfer. The thermal and hydraulic performance of the water-ice slurry HX is evaluated by experiment and calculation. The experiment is run through a transient state (of 15 to 25 s) to reach the quasi steady state that lasts more that 30 s. The experimental data in the steady state is analyzed in the present study for evaluation of the TES system. The model predicted heat rates are lower than the experimental values by 12% to 22%. The predicted dimensionless pressure drops are within ±12% of the experimental data for the ice slurry flow and within ±6% for the water flow.
