ELECTRONIC MOISTUREPROOF STORE

摘要

PURPOSE:To keep the humidity in a stocker almost constant by calculating temp. on an endothermic side on the basis of the store detection temp. of the second temp. sensor in order to realize objective humidity and controlling the supply of a current to a thermoelectric element while monitoring temp. by the first temp. sensor so as to keep the temp. on the endothermic side. CONSTITUTION:An electronic cooling apparatus 10 using a thermoelectric elements 12 is allowed to face the interior of a store 7 on the endothermic side 14 thereof and the temp. on the endothermic side 14 is lowered to a dew point or lower to condense water vapor in the store 7 and the generated waterdrops are discharged out of the store 7 to lower the humidity in the store 7. At this time, the first temp. sensor 30 is brought into contact with the electronic cooling apparatus 10 on the endothermic side 14 thereof and the second temp. sensor 32 detecting the temp. Ts of the air in the store 7 is provided. The temp. on the endothermic side for realizing objective humidity is calculated on the basis of the detection temp. TA of the sensor 32 by a control apparatus 40 and the supply of a current to the thermoelectric element 12 is controlled so as to keep the temp. on the endothermic side while the surface temp. TC on the endothermic side 14 is monitored by the sensor 30. As a result, the humidity in the store can be kept almost constant.
