Cold storage shelf structure in detail

Shelves refrigerated warehouse is refrigerated warehouses for refrigerated cargo storage place. The goods after the precooling, achieve preservation of mixed evenly and send such as refrigerated warehouse pallet storage, asked if a small amount of goods is directly deposited in the cold storage refrigeration. Generally USES air-cooled refrigeration, refrigerated warehouse with cooling fan cooling. In order to prevent the goods within the crib, keep breathing fresh air curtain by goods circulation, cold storage commonly adopt the way of ranks crib pallet storage. Because of the cold storage for a shorter, the goods in the house of the rolls handling frequency is higher, pallet stacking ideal in groups. Cooling and freezing room of cooling and freezing, also known as pre cold between libraries. Goods before entering the refrigerated or frozen warehouse, first between cooling or freezing cold treatment, the uniform cooling of goods to a predetermined temperature, cooling for the refrigerated goods 2 other 4 & # 39; t; Quickly dropped to - frozen goods 20 ' T make frozen goods. Shelf freezer warehouse via precooling reach the freezing temperature of frozen cargoes to preserve between longer-term Treasury. The goods after precooling, into refrigerator stacking haulms). Frozen cargoes pile the goods generally smaller, in order to reduce the internal temperature, cargo crib use pallet or tray at the bottom of the mat is high, the goods are not direct contact with the ground, to avoid temperature fluctuations when water freezes again after the goods and the adhesion of the ground. Distribute ask the delivery of goods to quickly carry goods from a refrigerated or frozen warehouse will be moved to the distribution between, between distribution operation, from the distribution between the shipment. Distribution of temperature is low. But as a result of directly to the warehouse operation, temperature fluctuation is bigger, so distribution frowsty cannot be stored goods. Shelves cold storage equipment generally cold storage is much by refrigerator refrigeration, the use of gasification temperature is very low liquid ( Chlorine or freon) As a coolant. To make it evaporate under the condition of low pressure and mechanical control, absorb the heat inside the vault, thus achieve the purpose of cooling down is wet. The most commonly used is the compression type refrigerating machine, mainly consists of compressor, condenser and evaporation sale & # 39; And so on. According to the evaporation its & # 39; Device the way and can be divided into direct and indirect cooling cooling two kinds. Will direct cooling evaporation tube & # 39; Installed inside a refrigerated warehouse, liquid cooling 3 & # 39; IlJ after low pressure evaporation tube, direct absorption heat and cooling in the warehouse. Indirect cooling by fan will air suction inlet air cooling device in the warehouse, the air is hovering in the cooling device of evaporation tube after absorption of heat, into the house of the rolls and cool again. Indirect cooling method has the advantage of cooling is rapid, uniform temperature inside, at the same time will be generated in the process of the storage of carbon dioxide and other harmful gases with outbound.
