PLANT CULTIVATION APPARATUS

PROBLEM TO BE SOLVED: To provide a plant cultivation apparatus which prevents non-uniformity of air environment even in a large-scale apparatus and is capable of creating environment adapted for plant growth.SOLUTION: In a plant cultivation apparatus 1, a plurality of multistage cultivation shelves 10 on which a plurality of stages of cultivation shelves 11 are installed in a vertical direction are arrayed on a plane in a room, and space between the multistage cultivation shelves 10 is constituted alternately as: a cold aisle 20a whose upper part is closed and in which air-conditioned air flows in from a bottom part and moves upward; and a hot aisle 20b in which air having passed through the multistage cultivation shelves 10 from the cold aisle 20a moves upward, and is exhausted from an exhaust port 5a provided at the upper part. 【課題】大規模なものであっても、空気環境の不均一性を防いで植物の生育に適した環境とできる植物栽培設備を提供する。【解決手段】植物栽培設備１では、室内に、上下方向に複数段の栽培棚１１を設置した多段式栽培棚１０が平面に複数並べられ、多段式栽培棚１０の間の空間を、交互に、空気調整された空気が下部から流れ込み上方に移動する、上部が閉じられたコールドアイル２０ａと、コールドアイル２０ａから多段式栽培棚１０を通過して流れ込んだ空気が上方へ移動し、上部に設けた排気口５ａから排気されるホットアイル２０ｂとして構成する。【選択図】図１
