Ice-temperature freshness-preservation storehouse for fruits and vegetables

The utility model discloses an ice-temperature freshness-preservation storehouse for fruits and vegetables, and aims to provide an ice-temperature freshness-preservation storehouse for fruits and vegetables which has the advantages of high-precision control as well as extremely uniform wind field and temperature field, and can meet the requirements of ice-temperature storage. A storehouse body comprises a bottom-layer insulating layer, as well as an outer-layer insulating storehouse body and an inner-layer non-insulating storehouse body which are connected with the bottom-layer insulating layer, wherein an air interlayer serving as an air return passage is arranged between the inner-layer non-insulating storehouse body and the outer-layer insulating storehouse body, a plurality of cold airblowers which are connected in parallel for alternative work or defrosting are mounted in the air interlayer at the top part of the outer-layer storehouse body, a top air supply pore plate is arranged in the interior of the inner-layer storehouse body, a static pressure tank layer is formed between the top air supply pore plate and the top part of the inner-layer non-insulating storehouse body, aplurality of air return inlets are formed on the periphery of the bottom part of the non-insulating storehouse body, and temperature sensors are arranged below the static pressure tank layer and at the air return inlets. The utility model has the advantages that the temperature inside the ice-temperature freshness-preservation storehouse for fruits and vegetables is stable, the velocity field andthe temperature field are uniform, no impacts can be caused on temperature inside the storehouse during defrosting, the control accuracy is high, and the temperature fluctuation inside an empty storehouse is within plus or minus 0.3 degree.
