PROBLEM TO BE SOLVED: To provide a potato warehouse in which weather conditions in snow cold districts are utilized and power consumption is reduced.SOLUTION: The warehouse comprises two rooms for storing potatoes and a front room. The temperature in the two rooms rises by the respiration heat of the potatoes during a winter period from November to next year March, so that +2°C of inside air is mixed with a negative temperature of outside air to become 1°C by a cold air circulation-type, and then the mixed air is supplied to the inside two rooms to refrigerate the potatoes. The warehouse becomes a vacant space in about the middle of March, however, a vacant steel container is packed with snow and carried into the interior of the room again to be housed as a cold heat source. The other one room side stores potatoes in a full state continuously from a harvest time. In the summer after April, an over-slider for partitioning the two rooms is lifted up, and a cool air is moved from a room storing snow and ice to a room storing the potatoes by natural convection. In the midsummer when a load of outside air and sunshine is increased, the natural convection is supplemented by using a blower attached to the partition upper part, and a predetermined temperature of the room is secured.COPYRIGHT: (C)2015,JPO&INPIT【課題】積雪寒冷地の気象条件を生かした、電力消費の少ないバレイショ倉庫の提供。【解決手段】その倉庫は、バレイショを収納する二室と前室とし、11月から翌年3月までの冬期間は、バレイショの呼吸熱で二室の温度が上昇するため冷風循環方式で、庫内空気のプラス2℃と外気のマイナス温度を1℃になるように混合し、その混合空気を庫内二室へ供給しバレイショを冷蔵し、3月中旬頃には空き空間となるが、空いたスチールコンテナに雪を詰め、再度室内に搬入し冷熱源として収納しておき、もう一室側はバレイショを収穫時期から継続して満杯状態とし、4月以降の夏期には、二室を仕切っているオーバースライダーを上げ、自然対流により雪氷を収納している部屋から、バレイショを収納している部屋へ冷気を移動させ、外気、日射の負荷が高まる盛夏には、間仕切り上部に取り付ける送風機により、自然対流を補足し部屋の所定温度を確保する。【選択図】図1
