Patent number: 11867457Abstract: 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.Type: GrantFiled: June 13, 2022Date of Patent: January 9, 2024Assignee: Morgan State UniversityInventors: Seong W.

Patent number: 8784529Abstract: Dehumidifiers having improved heat exchange blocks and associated methods of use and manufacture are disclosed. A heat exchange system in accordance with a particular embodiment can include a plurality of elements with a plurality of airflow channels. A plurality of peripheral spacers are positioned toward edges of neighboring elements and extend in a first direction. A first airflow path extends in the first direction, and is at least partially defined by the corresponding elements and the peripheral spacers. A second airflow path is defined by the airflow channels and extends in a second direction, and an airflow blocker is positioned at a corner portion of the elements to prevent fluid communication between the first and the second airflow paths at the elements. In certain embodiments, the heat exchange system can further include a dehumidifier having an evaporator positioned between the first and second airflow paths.Type: GrantFiled: October 15, 2012Date of Patent: July 22, 2014Assignee: Dri-Eaz Products, Inc.Inventors: Richard A.
