The invention discloses an air-conditioning storage method, which comprises the following steps of: a, laying a protection pad layer on the ground; b, laying a
composite membrane bottom sleeve on the protection pad layer; c, stacking the stored objects on the
composite membrane bottom sleeve; d, laying a top membrane on the top of the stored object stack, and then covering a
composite membrane top cover; e, thermally sealing the composite membrane bottom sleeve and the composite membrane top cover together by using a plastic envelope
machine, and reserving a hole; f, connecting an exhaust fan at the reserved hole in the step e to exhaust the gas in the stack so as to make the composite membrane attach the stored objects; g, forming a
small hole on the opposite side of the reserved hole of the composite membrane, and connecting a
gas detector; h, filling
nitrogen and / or
carbon dioxide into the reserved hole in the step e, and stopping filling when the concentration of the gas measured by the
gas detector reaches the preset concentration; and i, sealing all the holes by using a thermal plastic envelope
machine, and finishing the storage. The air-conditioning storage method can rapidly kill various insects in the stored objects, suppress mold growth, and guarantee the quality of the stored objects.
