  • AC electric field-assisted refrigerating container
    Patent number: 11493258
    Abstract: An AC electric field-assisted refrigerating container comprises: an outer container casing made of metal and having a storage chamber thereinside; an inner container casing formed of a dielectric panel and disposed inside the outer container casing; cooling means to cool an inside of the storage chamber; a plurality of insulated electrodes each formed by densely covering an entire circumference of an electrode plate with an insulator and disposed on an inner wall of the inner container casing; and a transformer for supplying an AC of 10 to 20 VA, at a voltage of 2000 to 4000 V and a frequency of 50 to 60 Hz, wherein the transformer has a ground terminal; wherein the refrigerating container is configured to cause AC discharge from the insulated electrodes to form an AC electric field inside the storage chamber, wherein, as a result of the AC discharge, electrons are supplied to the inner container casing formed of the dielectric panel, and then flow throughout the inner container casing, thereby allowing the e
