Convective heat exchange is better than conduction The dynamic ice storage tank is based on the theory that the convective heat exchange is better thsn conduction . The tank has been divided to several chambers by partition and the small circular pump guide Water flow through every chamber up and down circularly , thus the dynamic circulating chilled water flow may arise from minimum power pump ( aboutl～2 HP per tank ) , and then the flow generating the convective heat exchange between inner brine and outer chilled water to raise the freezing effect in charging process . The circulating water flow will agitate steady water layer between brine and chilled water to break resistance in the discharge process of tank . This result will improve discharge effect and exert storage energy in the tank completely . For the description given above , it’s not only the basic theory but also advantage of dynamic ice storage tank . In general , brine is circulating in the tube and storage water will be frozen on the outer . Because of the heat exchange between still ice and brine is conduction , so that effect of ice charge is poor . In the beginning of discharge , the ice where near the walt of tube is melting rapidly and then generate still water layer as thermal resistance to reduce discharge effect between brine and ice . TO make matters worse , the remanent ice can t be melting in the final of discharge process. 2 . Two - way melting ice caused double effect . The returning chilled water caused power to substitute for the circulating pump is the other character of dynamic ice storage tank . The chilled wster melts ice in the outside and brine in the inside concurrently , two - way melting ice will csuse double effect .
