以上の構成に基づき、本実施の形態に係る冷凍冷蔵庫１内外の冷気等の循環構造について説明する。
冷凍冷蔵庫１内では、複数の冷却装置４により吹出された冷気が冷凍冷蔵庫１内を冷却するとともに、図１に示すように、カーテン部材１２，区画板１１により規制されて第１送風装置６に送られる。この場合、冷却装置４からの吹出しは、第１送風装置６の吹出し方向に対し略垂直（略水平方向）となるようにすることが好ましい。第１送風装置６は、庫内の冷気を下方に吹出し、冷凍冷蔵庫１内の床に設置された吸気装置８で吸込むことにより商品搬出口５に冷気エアカーテンＣＡが形成され、吸気装置８を経て庫内に吹出されることにより、冷凍冷蔵庫１内が−１０℃等、所定の温度に保冷される。
一方、冷凍冷蔵庫１外では、冷凍冷蔵庫１の上方に設置された熱交換器９により暖められた外気を第２送風装置７により下方に吹出すことにより、商品搬出口５の外側に外気エアカーテンＦＡが形成され、作業スペースが５℃程度に保たれる。
この場合、上部断熱壁２ａの下端の断熱パネル１０により、各エアカーテンＣＡ，ＦＡの乱れを防止している。即ち、冷凍冷蔵庫１内が負圧となるため、断面で見た場合に、上部側では庫内への外気の侵入が起きる一方、下部側では冷気の吹出しが起きることとなる。従って、上部側において、第１送風装置６からの吹出しが庫外側に向くように庫内側を傾斜面に形成している。さらに、下部断熱壁２ｂを立ち上げることにより、下部側でのコールドアイルの発生を防止している。
また、吸気装置８の吸込み風量を、第１，第２送風装置６，７の吹出し風量の合計よりも少なくすることにより、庫内への外気の流入を防止している。 Based on the above configuration, a circulation structure for cold air inside and outside the refrigerator-freezer 1 according to the present embodiment will be described.
In the refrigerator 1, the cold air blown out by the plurality of cooling devices 4 cools the inside of the refrigerator 1 and is regulated by the curtain member 12 and the partition plate 11 as shown in FIG. Sent. In this case, it is preferable that the blowout from the cooling device 4 is substantially perpendicular (substantially horizontal direction) to the blowout direction of the first blower 6. The first air blower 6 blows out the cool air in the refrigerator downward, and sucks it with the air intake device 8 installed on the floor in the refrigerator 1, thereby forming a cold air curtain CA at the product outlet 5. Then, the inside of the refrigerator-freezer 1 is kept at a predetermined temperature such as −10 ° C. by being blown into the cabinet.
On the other hand, outside the refrigerator 1, the outside air heated by the heat exchanger 9 installed above the refrigerator 1 is blown downward by the second blower 7, so that the outside air curtain is placed outside the product outlet 5. FA is formed and the work space is kept at about 5 ° C.
In this case, the air curtain CA, FA is prevented from being disturbed by the heat insulating panel 10 at the lower end of the upper heat insulating wall 2a. That is, since the inside of the refrigerator-freezer 1 has a negative pressure, when viewed in a cross section, outside air enters the cabinet on the upper side, while cold air blows off on the lower side. Therefore, on the upper side, the inside of the warehouse is formed as an inclined surface so that the blowout from the first blower 6 faces the outside of the warehouse. Furthermore, by raising the lower heat insulating wall 2b, the occurrence of cold aisle on the lower side is prevented.
Further, by reducing the intake air volume of the intake device 8 from the total of the blown air volumes of the first and second air blowers 6 and 7, the inflow of outside air into the cabinet is prevented.

作業フロアＦにおける流れとしては、搬入装置及び移載装置による商品の補充，作業者によるピッキング作業，搬出装置による配送商品の搬送の順で行われる。
