Performance of a Direct Evaporation Thermal Storage System

A direct evaporation ice-on-coil thermal storage experimental equipment was designed with the copper tube of diameter 16 mm and wall thickness 1 mm. The direct evaporation ice-on-coil can be arrayed at 100 × 100 mm (system A), 100 × 50 mm (system B) or 60 × 60 mm (system C). The static state as well as dynamics direct evaporation ice-on-coil thermal storage experiment was done with disturbance and non-disturbance of the refrigerating medium (water) in the ice bank tank. The experimental results show that with the increasing of the ice-on-coil array density, the thermal storage system performance improved markedly, and the performance of the disturbance system is better than the non-disturbance. According to the results of the direct evaporation ice-on-coil thermal storage experiment, compared with system A, system C shortens the time for 2-3 hours at the same storage capacity.
