10.30.20. Cold Any temperature not exceeding 8° (46° F) is “cold.” A “refrigerator” is a cold place in which the temperature is maintained thermostatically between 2° and 8° (36° and 46° F).
以前用这个单词,都是用冷藏的意思 去google了一下wikipidia,看来没有用错,呵呵 A refrigerator (often called a "fridge" for short) is a cooling appliance comprising a thermally insulated compartment and a heat pump—chemical or mechanical means—to transfer heat from it to the external environment, cooling the contents to a temperature below ambient. Refrigerators are extensively used to store foods which spoil from bacterial growth if not refrigerated. A device described as a "refrigerator" maintains a temperature a few degrees above the freezing point of water; a similar device which maintains a temperature below the freezing point of water is called a "freezer."
