Refrigerated facilities are any buildings or sections of a building that achieve controlled storage conditions using refrigeration. Two basic storage facilities are (1) coolers that protect commodities at temperatures usually above 32°F (0°C) and (2) low-temperature rooms (freezers) operating under 32°F (0°C) to prevent spoilage or to maintain or extend product life.
