In a cold storage warehouse, by developing the thermal energy storage technique using cheap electric powerin the night, it is necessary to construct a high-efficient and energy-saving-type refrigeration system in which air conditioning is possible at 0 degrees c. We created a brine iced water (ice slurry) cooled under 0 degreesc by a closed supercooling ice making method. For a practical application, the brine iced water was directly sent to the load side, and it was utilized as the secondary refrigerant for the heat exchange. As a result, by replacing the pure water with a marketed propylene glycol solution, it was proven that the conventional closed supercooling ice making method could be similarly utilized for the ice making. However, it is necessary to control the evaporation temperature in the refrigerator, because the freezing temperature changes with the brine concentration. In the refrigerator entrance, it is necessary to heat at a constant temperature so that the inflow brine may not freeze. In case of the brine iced water, the fluidity of the brine iced water is high, and the ice particle is carried away by the flow. Therefore, it is necessary to prevent runoff of the ice particle from an intake of the thermal storage tank in case of thebrine water. This proposal system was confirmed that there was practically no problem by an operation of a 15kW refrigerator system.
