<p>PROBLEM TO BE SOLVED: To compensate a sense error among respective temperature sensors and to always ways keep a balance of the temperature in a cold room by calculating an error value of mean detection temperature of each temperature sensor based upon a reference temperature sensor and finding a correction temperature value. SOLUTION: When the temperature in the cold room is balanced, an arithmetic part 11 of a microprocessor 10 calculates the mean detection temperature of respective sensors 3, 4, and 5 from detection signals generated by temperature sensors 3 and 4 for the cold room and a temperature sensor 15 for a freezing room, and then regards an optionally selected temperature as a reference sensor to calculate the error values of mean detection temperatures of the remaining temperature sensors and adds the error values of the actual detection temperature values of the temperature sensors to find the correction temperature value. The correction temperature value is supplied to a control part 12 of a microprocessor 10 and used as a control value for a compressor control part 17, a damper control part 18, and a cold air discharge direction control part 19. The error value is stored in the memory 13 and used for temperature control by the microprocessor 10.</p> |
