Abstract: A hybrid shellfish cooling system employs DC and AC cooling units using both solar power and AC electrical supply as energy sources. As temperature control and uniform temperature distribution in the cooling system are critical factors in reducing vibrio growth on raw oysters and reducing energy consumption, the system is equipped with a divider that optimizes airflow through the cooling system interior cabinet to achieve uniform temperature distribution in six individual internal compartments. Tests indicated that an average of 130 min. cooling was required to reach the suggested oyster temperatures of 7.2° C. and meet the cooling time requirement (i.e., 10 h or less). Airflow is further optimized via fan location and airflow direction, whereby configuration of a circulation fan on a lower part of the 12-volt DC section with an air supply from the 12-volt DC section to the 110-volt AC section achieves relatively uniform temperature distribution.

Based on a multi-phase finite impulse response (FIR) filtering technology, a fractional multiple delay processing architecture that can flexibly adapt to a plurality of phase quantities of the input signal is proposed.
