Ventilation and cooling project of SS-EAC series filtered air cooler for a supply chain warehouse in Dongguan

【 Project Background: Dual Challenges of High Temperature and Cleanliness 】

This project is located in Dongguan, Guangdong. Dongguan is located in the subtropical monsoon climate zone, with long and high temperature and humidity summers, with an average annual temperature exceeding 22 ℃, which poses a severe challenge to the temperature and humidity control of industrial production and storage environments. As the core city of the "world factory", Dongguan has a highly developed supply chain industry and is an important logistics hub in southern China and even the whole country. The efficiency of warehousing turnover directly affects the stable operation of the industrial chain.

As a key supply chain node in the region, this warehouse mainly undertakes the turnover tasks of food, medicine, and some light industrial products. Food and drugs are extremely sensitive to storage environments: high temperatures can easily cause food spoilage and changes in drug properties, while dust and microorganisms in the air may cause cross contamination, affecting product quality and safety. In addition, the warehouse has a huge area and high floor height, which is a typical high-rise space building. Natural ventilation is difficult to meet the demand, and there is a clear phenomenon of "heat up and stuffiness down". An efficient and clean ventilation and cooling solution is urgently needed.

Ruifeng Solution: Customized "Clean+Cooling" Integrated Design

In response to the special requirements of this project, the design team of Ruifeng Environmental Protection Refrigeration has comprehensively considered the high temperature and humidity geographical climate of Dongguan, the air flow characteristics of tall spaces, and the high cleanliness requirements of food and medicine. They have abandoned traditional single function cooling equipment and customized a system layout of high-power stainless steel filter air coolers (SS-EAC series) and large stainless steel ducts.

The core design logic of this scheme is as follows:

1. One machine dual-use, functional integration

The core advantage of the selected SS-EAC series stainless steel filter air cooler is the integration of "air filtration" and "environmental cooling". When the equipment is running, the outdoor air first passes through a multi-layer filtration system and is purified to a high standard cleanliness; Subsequently, an efficient wet curtain is used for evaporative cooling, utilizing the physical principle of water evaporation to absorb heat, effectively reducing the air temperature; Finally, the processed clean cold air is sent into the environment by an efficient motor and fan blade power system. According to on-site measurements, the lowest temperature at the air outlet of the equipment can be stabilized at 27-28 ℃, achieving a significant cooling effect compared to outdoor high-temperature environments.

2. Quadruple filtration, layer by layer purification

To meet the strict requirements for air cleanliness in food and pharmaceutical warehouses, the equipment is equipped with a quadruple filtration system:

1) Protective filter screen: As the first barrier, it effectively blocks large particles such as sand and stones, dead branches, flying fluff, and garbage debris, protecting subsequent filters and core components inside the equipment.

2) Primary filter: As a pre filtration layer, it mainly intercepts larger particles with a diameter of ≥ 5 μ m, such as metal debris, wood chips, dust, fluff, mosquitoes, etc., to extend the service life of medium and high efficiency filters.

3) Medium efficiency filtration layer: This is a less commonly used deep filtration layer in the market, focusing on filtering small particles of 1-5 μ m, providing a cleaner air foundation for the next level of high-efficiency filtration, ensuring overall filtration efficiency.

4) Efficient filtration layer: As the ultimate purification layer, it efficiently adsorbs and filters submicron particles (≤ 0.3 μ m), effectively removing harmful substances such as PM2.5, viruses, and bacteria. Its filtration standards can meet the purification requirements of operating room level, fully ensuring the storage safety of food and drugs.

3. Excellent product strength, sturdy and durable

1) Durable and sturdy: The whole machine adopts a stainless steel body, which has excellent corrosion and oxidation resistance. It is still "sturdy and durable" in the complex environment of the warehouse, and its service life far exceeds that of ordinary equipment.

2) Efficient cooling: Equipped with 5090 high-quality wet curtains, with excellent water absorption and hydrophilicity, the cooling efficiency is industry-leading. The design of four sided air intake significantly increases the air intake area and cooling area, and can achieve efficient cooling of 4-8 ℃ under high temperature conditions in Dongguan during summer.

3) Intelligent control: Provides various control systems such as air switches, LCD controllers, and variable frequency controllers, which can flexibly adjust the operating status according to the actual temperature and humidity changes in the warehouse, achieving a perfect balance between energy conservation and comfort.

4) Convenient maintenance: The filter layer adopts an insertable industrial design, which allows for easy replacement of the filter element without the need for complex tools, greatly reducing daily maintenance costs and time.

5) Highly customized: Different materials such as 304 stainless steel, 316 stainless steel, and high zinc galvanized sheet can be flexibly selected according to customer needs. Special models such as explosion-proof and copper iron zinc free can also be customized to meet various special scenario requirements.

4. Large air duct, uniform air supply

This project uses large stainless steel ducts as the air distribution system. Its design cleverly utilizes the principles of aerodynamics: through the reasonable layout of air ducts and precise calculation of pipe sizes, the large air volume and high cleanliness cold air generated by the air cooler are evenly transported to every corner of the warehouse at a lower flow rate, effectively solving the problem of "uneven heating and cooling" in tall spaces and achieving ventilation and cooling effects with no dead corners and uniform temperature throughout the entire warehouse area.

5. Project Value: Environmental Upgrade, Benefit Enhancement

After the equipment was put into use, the warehouse environment was fundamentally improved. Continuous and stable temperature and humidity control, as well as clean air, create a nearly constant temperature and sterile storage environment for food and medicine, effectively ensuring product quality and significantly reducing the risk of loss caused by environmental factors. The improvement of working environment comfort has directly promoted the work efficiency of warehouse personnel, resulting in an overall increase of about 20% in warehouse turnover efficiency and creating considerable economic benefits for the enterprise.

Case extension: The boundary of ability is not limited to this

Although this project is a supply chain warehouse scenario, the core value of its solution - comprehensive selection and solution design capabilities for special spaces and usage scenarios - can be perfectly replicated in a wider range of fields. Ruifeng Environmental Protection Refrigeration, with a deep understanding of the SS-EAC series stainless steel centrifugal air cooler series and highly customized technical chain adaptation capabilities for "ventilation and cooling+stainless steel air cooler products", can provide in-depth services from "scene diagnosis" to "solution design" and then to "product landing" for different fields such as clean rooms, big data centers, desert cities, hospitals, food factories, and aquaculture industries. We always adhere to the ability testing standards of "deep exploration of practical needs, high degree of implementation, and product durability", and are committed to achieving universal coverage in all industrial, commercial, and agricultural scenarios.
