Aluminum alloy pipes and seamless steel pipes are the same, can be applied to ammonia working fluid, can also be applied to Freon working fluid. The surface of aluminum alloy row pipe is provided with a 11渭thick anti-corrosion layer, which is more suitable for low temperature and humid environment than seamless steel pipe row pipe.

2. The effective utilization rate of cold storage room. In the cryogenic freezer, the aluminum alloy top-row pipe is generally installed in a single row, which is smaller than the traditional double-layer seamless steel pipe top-row pipe occupying the space in the storage, which is beneficial to improve the cargo stacking height of the cryogenic refrigerated warehouse, that is, the actual and effective utilization rate.

3. The effect on the quality of refrigerated food. In cryogenic storage, the use of aluminum alloy top-row pipe instead of chiller can not only reduce power consumption and save energy, but also make the temperature of refrigerated storage more uniform and stable, thus reducing the dry consumption of refrigerated food and improving the quality of refrigerated food.

4. It is suitable for the types of cold storage. Aluminum alloy row pipe is generally suitable for low temperature cold storage as top row pipe evaporator. For freezing rooms, aluminum alloy exhaust pipe chillers or shelf aluminum alloy exhaust pipes can be used as evaporators. For high temperature storage, aluminum alloy exhaust pipe cooler can be used as evaporator. Because of the thermal conductivity of the material, the aluminum alloy exhaust air cooler and shelf type aluminum alloy exhaust pipe have better heat transfer efficiency than the seamless steel pipe exhaust fan and shelf steel row pipe.

5. Matters needing attention in the application of aluminum alloy row pipe: 1) the design, manufacture, installation and debugging of aluminum alloy row pipe. It should be undertaken by an experienced company with the qualification of cold storage design and installation. After the manufacture of aluminum alloy exhaust pipe, single pressure test and sewage discharge should be carried out. Then, connect the refrigeration system installation. After the installation is completed, the pressure test leakage, sewage discharge, vacuum and refrigerant test leakage of the refrigeration system should be carried out. 2) the selection of heat transfer area of aluminum alloy row pipe. The heat transfer area of aluminum alloy pipe in cryogenic storage is generally determined by 1.3 ≤ 1.6 times of the net area of the storeroom, the freezing room is generally determined by 8 × 10 times of the net area of the storeroom, and the cooling room is generally determined by 3.5 times of the net area of the storeroom.
