What are the advantages of the aluminum row pipe in the cold storage, in the cold storage, the air c

1. The evaporator of the cold storage refrigeration system with aluminum row is not only much more energy-efficient than the steel pipe or air cooler, but also can extend the service life of the compressor. In the long run, the money saved in these two aspects is much greater than the difference between the price of aluminum bars and steel pipes or air coolers.

Second: the evaporator of the aluminum row as a cold storage refrigeration system can save more than 30% energy compared with steel pipes or air coolers. This is mainly because aluminum alloy has good thermal conductivity, and the thermal conductivity of aluminum is twice that of iron.

The heat transfer coefficient of the energy-saving aluminum row is twice that of the steel bar, and only the top row pipe can meet the cooling capacity requirements.

Three: the aluminum bar also has light weight and easy installation - under the same evaporation area, the weight of the aluminum bar is one-sixth of the steel bar; The amount of refrigerant used in the system is low - the structure of the aluminum row is reasonable, the internal ribs increase the contact area of the refrigerant, and the external fins increase the contact with the air, which greatly improves the utilization rate of the refrigerant; Reasonable structure, accelerated convection, rapid refrigeration - the fin tubes are connected in parallel to form a number of parallel convection channels, and the cold air forms a flue effect in the channel when the refrigeration system is running, and the cold air accelerates the sinking, the convection accelerates, the cooling speed accelerates and the food dry consumption is less, and the electric heating defrosting function solves the problem of dripping water in the high-temperature reservoir and many other advantages.

The answer refers to the address.

The aluminum tube is lightweight, saving space around.

Air cooler pipe: there are large and small, high and low temperatures. Pipe: There are aluminum rows and iron rows, which are mostly used for low-temperature meat products.

Air cooling: good refrigeration effect, fast speed, clean in the warehouse, not damp, once the power is off, the temperature in the library is easy to lose, power consumption, low cost, easy to transform in the future, but it is easy to dry the moisture in the product, so that the product folds the scale, not glamorous and so on.

Tube cooling: the refrigeration effect is slow, there is more water and ice in the warehouse, the installation is inconvenient, the cost is slightly higher, the power is saved, and the temperature can be extended for a period of time once the power is off, and it is not easy to transform. It is suitable for vegetables and fruits, ice cream cold drinks, fresh meat, etc.

The advantages of aluminum tube cold storage are as follows:

1. Good thermal conductivity: the aluminum alloy with good thermal conductivity used in the cold storage of aluminum tubes, in this case, the evaporation temperature of the refrigerant used in the cold storage and the surface temperature difference of the outer surface will be reduced, which is extremely helpful to the improvement of the evaporation temperature.

2. Good equipment and low energy consumption: the projection area and evaporation area ratio of aluminum pipe are relatively large, if set on the top of the cold storage, it can greatly increase the operating power per unit area, improve efficiency, and save energy and environmental protection. In addition, the cold storage effect of the aluminum pipe is good, so that the frequency of start-up can be reduced, and the energy consumption can be reduced.

3. Light weight and simple installation: the weight of the aluminum pipe and the area of the evaporator are relatively low, and there is a big gap between the ratio and the steel pipe, which is extremely small. Therefore, the time and effort required during installation is very small.

4. Low amount of refrigerant: the aluminum bar uses excellent fin tubes with external fin and internal threads. This type of fin tube has great advantages in terms of the use of refrigerants, such as a reduction in the amount of injection and a reduction in the cost of refrigerant.

Cold storage pipe is an indispensable part of cold storage, cold storage pipe plays an important role in the installation of cold storage, Guangzhou Shengya refrigeration tells you that its advantage is that the thermal conductivity of the pipe is good: aluminum alloy has excellent thermal conductivity, the evaporation temperature of the refrigerant and the temperature difference between the outer surface of the aluminum row will be reduced, the evaporation temperature will increase, the energy efficiency ratio of the compressor will increase, and the energy consumption will be reduced.

The life of the cold storage aluminum pipe is about 20 years.

Aluminum pipe, mainly used in the refrigeration system of 10 to -45 cold storage, is an evaporator used in all kinds of food freezing and cold storage. Dongli refrigeration, the inlet and outlet part of the aluminum pipe uses high-frequency resistance to weld copper-aluminum joints, the thickness of the aluminum pipe is 2mm, there is no difference, and the pressure is resistant. Cooling capacity of aluminum exhaust, K value 10W (m2· ) Average], according to the cold storage design specification, q=k·a·δt, the temperature difference taken in the actual proportioning process δt=10.

Considering the problem of frosting in cold storage, the aluminum pipe of the general low temperature storage is calculated according to the lower limit of 90w m2 to prevent insufficient cooling capacity after frosting. The high temperature library does not frost, and the upper limit is 140W m2.
