A temperature control device and temperature control method for a refrigerating
apparatus are provided. This system calculates an operation rate of a compressor
installed in the refrigerating apparatus, and controls operation of the compressor
based on the calculated operation rate, thus obviating the need for an outside
air temperature sensor and a damper to accurately control temperature. A heat generating
lamp may be positioned in the chilling chamber to further regulate chilling chamber
temperature. Operation of the heat generating lamp is also controlled based on
the operation rate of the compressor.
