PURPOSE:To not to waste electric or heating energy needed for moisture-proofing, by performing each automatical operation control of a refrigerator and a moisture-proof apparatus according to relative humidity between open air dew point temperature and desired low humidity atmosphere. CONSTITUTION:The dew point temperature range of open air 6 is determined by a detection signal from a dew point thermometer 25 through an operation controller 30, four refrigerator units 1-4 are ON/OFF-controlled according to the range, and the moisture-proof capacity of the whole refrigerator units is heightened when open air dew point temperature is high and is lowered when the temperature is low. In the meantime, the calculated relative humidity between a storage shed 10 and each paper-covering chamber 11-13 is required by the operation controller 30 through the detection signal from the thermometers 21-24 and the dew point temperature 26-29, and the highest relative humidity range among the four sections is determined. The opening of a damper 18 for adjusting the regenerating hot air quantity of the moisture-proof apparatus 7 according to said range is controlled. Thus, the driving energy of the refrigerator and the regenerating energy of the moisture-proof apparatus are not wasted.
