Cold Storage Construction Showdown: Aluminum Grilles vs. Fans, Choosing the Wrong One Costs Tens of Thousands?

Recently, some fans left messages in the background, asking how to build a cold storage facility exactly. Have you ever experienced the situation where an entire warehouse of frozen products was scrapped due to uneven refrigeration? Paying tens of thousands of yuan more in electricity bills every month but feeling at a loss? The main reason lies in two key choices: aluminum finned tubes vs. cold air fans!

Today, let's follow Fland to learn about the differences between aluminum exhaust silos and fan silos!

The first generation of traditional cold storage refrigeration mostly used tubular evaporators. With the increasing maturity of the technology of cold air machines, their advantages in energy conservation, dry consumption, cost and other aspects have become more and more prominent, gradually replacing tubular cold storage.

                                                                                            01Energy-saving comparison

The power consumption of an aluminum exhaust fan warehouse is greater than that of a cold air fan warehouse.

① The traditional tube-type evaporator is a natural cooling method. For the same evaporation area, the pipe length of the traditional tube-type evaporator is about ten times longer than that of the cold air fan. Due to the longer pipes, more refrigerant needs to be added, which increases the load on the refrigeration compressor unit and raises the power consumption.

② Traditional tubular evaporators cannot defrost automatically. After a very short period of time, there will be a lot of frost on the aluminum bars. If the frost is too thick, the heat transfer effect will decline. The temperature in the cold storage drops slowly, the refrigeration efficiency is low, which increases the operating time of the compressor unit and the power. consumption.

                                                                                                     02Dry loss comparison

The dry loss of the aluminum exhaust warehouse is greater than that of the cold air fan warehouse.

① When meat and other foods are placed in cold storage, due to the cold air blown out by the cold air blower at around -18℃, an ice shell quickly forms on the surface of the meat, preventing the evaporation of moisture. This effectively prevents dry loss.

② When using an aluminum fin evaporator, the temperature in the cold storage drops very slowly. Without cold air on the surface of the food, ice shells cannot form quickly. The moisture inside the food gradually evaporates onto the aluminum fins, forming frost and causing dry loss.

                                                                                                   03Cost comparison

①The power consumption of the aluminum exhaust fan warehouse is greater than that of the cold air fan warehouse, increasing the electricity bill.

② The dry loss of aluminum exhaust in the cold air fan warehouse is greater than that in the cold air fan warehouse, which reduces the weight and lowers the quality of stored meat products or other foods, directly causing economic losses.

③ The pipeline length of the aluminum exhaust pipe is about ten times that of the cold air fan, which increases the installation cost. 

④ The service life of aluminum exhaust silos is shorter than that of cold air fan silos, increasing operating costs.

⑤ The aluminum discharge warehouse cannot be defrosted automatically and requires regular manual defrosting by maintenance personnel, which increases the cost.

                                                                                                       04Conclusion

Fland cold storage uses aluminum-magnesium alloy cold capacity type air coolers. With a "small pipe diameter and dense" arrangement, it has a large heat exchange capacity, a small heat exchange temperature difference, low dry loss, is less likely to frost, and has high energy efficiency, making your food fresher.

Fland intelligent algorithm achieves the effects of defrosting on demand, defrosting when there is frost, and not defrosting when there is no frost, completely eliminating fan ice blockage.

Now, do you know how to choose when building a cold storage?
