Refrigerating temperature-controlled goods shelf

Abstract

The invention relates to a refrigerating temperature-controlled goods shelf. The refrigerating temperature-controlled goods shelf comprises stand columns, a middle support and a top-layer support. Thestand columns, the middle support and the top-layer support form a goods shelf body. A hollow interlayer structure is adopted as an air supply channel of the stand columns, the middle support and thetop-layer support, small holes are formed in the lower surface of each supporting layer, an inner pore plate air supply structure layer of the goods shelf is formed, and jet holes are formed in the outer side of the pore plate air supply structure layer. A fan, a refrigerating coil and a valve plate assembly are arranged in the space of the bottommost layer of the goods shelf body, and refrigerating fluid is introduced into the valve plate assembly to be throttled to form a low-temperature low-pressure gas-liquid two-phase state and then enters the refrigerating coil to be evaporated; after return air in the goods shelf passes through the refrigerating coil, the temperature is reduced, the return air is supplied into the stand columns by the fan, and cold air is supplied to the supports through the air supply stand columns and then supplied into the goods shelf through the small air supply holes and the jet holes in the lower surfaces of the supports, so that air supply in the good shelf is even; and air curtains are formed on the two sides of the good shelf for temperature isolation, and air supply circulation in the goods shelf carries out air return through clearances between the air supply interlayer of the supports.

Description

technical field [0001] The invention relates to a storage of goods in a cold storage, in particular to a refrigeration temperature-controlled shelf. Background technique [0002] At present, the general cold storage shelves are welded by stainless steel, with a simple structure, and only play a supporting role. The goods stacked on the shelves will affect each other and transfer heat, and the storage effect is not good. The shelves are placed in the entire cold storage. Due to the uneven temperature distribution in the storage, the storage period of the goods will be seriously affected in the local over-temperature area. In addition, only one temperature can be maintained in the cold storage, and goods with different optimal storage temperatures cannot be effectively distinguished. [0003] At present, some cold storages use cold-transfer-type shelves. There are airflow channels in the beams and columns, which can be used for cold air. The support beams use heat-transfer co...
