Iceless refrigerator Iceless refrigeratorA cabinet for holding food that had screenwire sides and a covering of porous cloth. The cloth was kept wet by being dipped in a pan of water. The water evaporating kept the cabinet cool. Evaporative cooling was the only kind of cooling possible when ice was not available and was also sometimes used for keeping drinking water cool. It was not, for example, uncommon to take a fruit jar filled with drinking water and wrapped with a damp gunnysack to the field each summer day. When a recirculating refrigerant began being used rather than a block of ice for cooling (i.e. the refrigerator of today), the machines were sometimes called iceless refrigerators. |
