Core Configuration — Air Cooler + Duct Mode with AI Intelligent Defrosting Function

Our low-temperature cold storage (-30~-18℃) adopts the mature and reliable air cooler + duct refrigeration mode, and adds the AI intelligent defrosting function at the same time. The three work together to ensure uniform air supply and efficient refrigeration, and completely solve the frosting problem of low-temperature cold storage, adapting to various scenarios of -30~-18℃ deep-freeze storage. The specific characteristics are as follows:

• Uniform Air Supply Without Dead Corners

In the scheme design stage, we will conduct professional air distribution calculation according to the length, width and height of the cold storage, the height and layout of goods stacking, and scientifically layout the installation position of the air cooler and the direction of the duct. After being cooled by the air cooler, the cold air is uniformly delivered to all areas of the cold storage along the preset duct, and then uniformly diffused through the air outlets reserved in the duct to form a stable circulating air flow, effectively avoiding local temperature deviation and ensuring that the temperature of every corner in the cold storage is stable within the set range (±1℃). This air supply mode completely eliminates the problems of "cold top and hot bottom" and "high temperature in corners" in traditional refrigeration methods, and is especially suitable for the storage of bulk and neatly stacked goods, ensuring that the goods at the bottom, top and corners are in the same stable low-temperature environment, and avoiding goods freeze burn, deterioration or quality decline caused by uneven air supply.

• Efficient Refrigeration and Energy Saving

The air cooler we select adopts high-efficiency copper tube and aluminum fin evaporator, which has high heat exchange efficiency and can quickly cool the air in the warehouse to the range of -30~-18℃, effectively shortening the cold storage start-up time (under no-load condition, it only takes 6~8 hours to cool from normal temperature to -18℃, and 10~12 hours to cool to -30℃); combined with reasonable duct design, it can reduce cold air short-circuit back flow, allow cold air to fully exchange heat with the air in the warehouse, improve refrigeration efficiency, and reduce the operation load of the refrigeration unit, thus reducing the enterprise's energy consumption cost. Compared with the traditional single refrigeration mode, this combined mode has significant energy-saving effect, with energy consumption reduced by 15%~25%, suitable for long-term continuous operation, able to meet the long-term freeze storage needs of large quantities of goods, and help enterprises reduce operating costs.

• AI Intelligent Defrosting, Efficient and Convenient

Aiming at the pain point that air coolers are prone to frosting and affect refrigeration efficiency in the low-temperature environment of -30~-18℃, we add the AI intelligent defrosting function. Different from traditional manual defrosting and timed defrosting, the AI system can real-time monitor the frosting thickness of the air cooler and the temperature change in the warehouse, intelligently judge the defrosting time and duration, and accurately control the defrosting process. It can not only completely remove the frost on the surface of the air cooler, avoid the reduction of refrigeration efficiency and increase of energy consumption caused by excessive frosting, but also avoid excessive temperature fluctuation in the warehouse caused by too long defrosting time or improper timing, maximizing the protection of goods quality; at the same time, AI defrosting can be completed automatically without manual operation, reducing labor costs, and the refrigeration system can be automatically adjusted during defrosting to ensure that the temperature in the warehouse is stable within a reasonable range, further improving the operation efficiency of the cold storage.

• Stable and Reliable Operation, Convenient Maintenance

The air cooler we select has a solid structure, corrosion resistance and low temperature resistance (suitable for low-temperature working conditions below -30℃), and is not prone to frosting blockage, component damage and other problems; matched with high-quality galvanized steel sheet duct, it has good sealing performance and is not easy to deform, which can effectively reduce cold air leakage and ensure stable refrigeration effect. The AI intelligent defrosting system is linked with the refrigeration system, which can automatically detect the operation status of the equipment, and timely find defrosting abnormalities, equipment failures and other problems, facilitating staff to deal with them in a timely manner; the later maintenance of the equipment is convenient, the air cooler can be regularly cleaned and inspected, the duct can be regularly cleaned, and the AI defrosting parameters can be remotely debugged, reducing the incidence of equipment failure, ensuring the long-term stable operation of the cold storage, and guaranteeing the safety of goods storage.

• Ensure Clean Storage Environment

The air cooler we select is equipped with a high-efficiency filter device, which has certain dust removal and demystification functions, can filter dust and impurities in the air, and reduce the generation of condensed water in the warehouse; matched with air supply through the duct with good sealing performance, it can effectively reduce external dust and moisture entering the warehouse, avoid the accumulation of dust and condensed water in the warehouse, and keep the storage environment clean and dry. The AI intelligent defrosting function can avoid condensed water residue during defrosting, further keeping the warehouse dry. This clean environment is especially suitable for food, medical and other goods with high requirements on storage environment, which can avoid the quality degradation and pollution of goods caused by dampness and dust, and ensure that the goods storage meets the industry compliance standards.

Intelligent Monitoring System — All-Round Protection for Low-Temperature Storage Safety

To fully ensure the safety of goods stored at -30~-18℃ and avoid goods loss caused by temperature fluctuation, abnormal frosting and equipment failure, we standard-equip an intelligent monitoring system for each set of low-temperature cold storage. The system adopts industrial-grade monitoring equipment, which is linked with the AI intelligent defrosting system and the refrigeration system to realize 24-hour uninterrupted intelligent management, covering real-time monitoring of multiple parameters such as temperature, humidity, frosting status and equipment operation status, ensuring the stability of the internal environment of the warehouse. The specific functions are as follows:

• Multi-Parameter Real-Time Monitoring

The platform is equipped with high-precision temperature and humidity sensors, which can accurately collect temperature and humidity data in different areas of the warehouse (such as the top, middle, bottom and corners of the warehouse) with a sampling frequency of once every 10 minutes. The data is stable and reliable with an error of no more than ±0.1℃, real-time feedback of the storage environment status; at the same time, it can real-time monitor the frosting thickness and defrosting status of the air cooler, as well as the operation parameters of the refrigeration unit and duct system, intuitively display the temperature difference in each area of the warehouse and the defrosting progress, facilitating staff to find and adjust in time to ensure that the internal environment of the warehouse meets the goods storage requirements.

• Data Traceability

The data curves of temperature, humidity, frosting status, equipment operation parameters, etc. are automatically recorded with a storage cycle of more than 1 year. Historical data can be queried and exported at any time (supporting Excel, PDF and other formats), which can trace the environmental parameters and equipment operation status of the whole process of goods storage, meet the compliance review requirements of food safety production, medical storage and other industries, and facilitate enterprises to keep relevant records and cope with various inspections and acceptances.

• Remote Convenient Management

It supports remote viewing through dual terminals of computer management platform and mobile APP. Staff do not need on-site duty, and can grasp the cold storage operation status, refrigeration unit working condition, duct air supply effect, AI defrosting progress and internal temperature and humidity data of the warehouse anytime and anywhere. At the same time, they can set temperature and humidity thresholds, adjust AI defrosting parameters and refrigeration system operation parameters through the remote terminal, greatly improving management efficiency and reducing labor costs.

• Abnormal Automatic Alarm

When the temperature and humidity in the warehouse exceed the preset range (such as the meat storage temperature exceeds -18~-22℃), or the air cooler has abnormal frosting, the AI defrosting system fails, or the refrigeration equipment and duct system fail (such as air cooler shutdown, duct leakage, refrigeration unit failure), the system will immediately send an alarm signal to the staff through multiple methods such as APP push, SMS reminder and phone call, reminding the staff to deal with it in the first time, minimizing goods loss and ensuring the safety of goods storage.

• Adaptation to Centralized Management

It supports centralized management of multiple cold storage and multiple regions. The operation data of multiple low-temperature cold storage can be uniformly connected to the management platform. Staff can monitor the operation status, temperature and humidity data, AI defrosting status and equipment working conditions of multiple sets of low-temperature cold storage at the same time, and can group manage and set parameters for different cold storage, with convenient operation and efficient management, truly realizing unattended and safe control, and adapting to the centralized management needs of large warehousing and logistics enterprises, multi-store fresh food enterprises and pharmaceutical enterprises.
