深圳，地处亚热带海洋性气候区，夏季漫长且高温高湿，对工业生产环境构成了严峻挑战。作为中国现代化智造产业的先锋城市，深圳汇聚了众多高精尖企业。其中，3D打印机制造作为推动工业4.0发展的关键技术，对生产环境的稳定性与洁净度有着极为严苛的要求。任何微小的温湿度波动或空气中的粉尘颗粒，都可能影响精密打印部件的成型精度和最终产品的良品率。

本次项目所在车间位于一栋多层钢筋混凝土结构的标准厂房内，该建筑结构具有良好的密闭性，但车间整体面积较大，人员与设备密集，导致内部热量积聚严重，通风不畅，急需一套高效且经济的通风降温方案来改善工作环境，保障生产品质。

【解决方案设计】

瑞峰环保制冷的技术团队在实地勘察后，综合分析了以下关键因素：

1）地理与气候： 深圳夏季高温，需要强劲的降温能力。

2）行业特性： 3D打印对空气洁净度有高要求，必须有效过滤粉尘。

3）建筑结构： 车间面积大且密闭，需要强大的送风与排风系统来形成有效气流组织。

4）经济性考量： 需避免传统工业空调的高能耗与高投入，寻求节能环保的解决方案。

基于以上分析，我们摒弃了能耗巨大的传统空调方案，创新性地采用了大功率不锈钢过滤冷风机（SS-EAC系列） 与负压风机相结合的综合通风降温布局。这一组合设计，是基于以下多重优势考量：

1、一机两用，实现洁净与降温的完美融合

该型号设备将“空气过滤”与“环境降温”两大功能集于一身。室外新鲜空气首先经过多层过滤系统，有效去除杂质，达到洁净要求；随后流经高效湿帘，利用水蒸发吸热的物理原理进行降温；最后，通过大功率离心风机将处理后的洁净冷空气源源不断地送入车间内部。在深圳夏季高温干燥的气候条件下，其出风口最低温度可降至27-28℃，实现显著的降温效果。

2、四级过滤系统，精准满足洁净度要求

针对3D打印行业的高洁净度需求，我们配置了专业的四级过滤系统，层层防护：

1）防护过滤网： 作为第一道屏障，有效拦截沙石、枯枝、碎屑等大颗粒物，保护内部滤网和核心部件。

2）初效过滤器： 对≥5μm的粉尘颗粒物（如金属碎屑、木屑、灰尘、毛絮、蚊虫等）进行预过滤，延长后续滤网寿命。

3）中效过滤层： 进行深度过滤，拦截直径在1-5μm范围内的细微颗粒，此配置在同类产品中较为少见，体现了我们对洁净度的极致追求。

4）高效过滤层： 作为终极净化屏障，可有效过滤亚微米级颗粒物（≤0.3μm），包括PM2.5、病毒及细菌，其净化标准可达到手术室级别，为精密制造提供了洁净保障。

3、产品核心优势，铸就耐用与高效

1）皮实耐造： 机身采用不锈钢（SS）材质，可根据需求选用304或316不锈钢，或高锌镀锌板，抗腐蚀性强，适应工业环境的严苛挑战，经久耐用。

2）高效降温： 配备5090型优质湿帘，具有极高的吸水性和蒸发效率。四面进风设计，增大了进风面积和制冷效率，可实现4-8℃的显著降温效果。

3）智能控制： 提供空气开关、液晶控制器、变频控制器等多种控制系统，满足不同场景的便捷操作与节能运行需求。

4）人性化设计： 滤层采用插入式设计，更换滤芯方便快捷，大幅降低了后期维护成本和时间。

5）高度定制： 可根据客户特殊需求，定制防爆型、不含铜铁锌型等特种冷风机，满足化工、精密电子等特殊场景的应用。

4、双机协同，形成科学的“抽拉式”气流组织

我们同时引入了负压风机，其原理是利用机械力量强制将车间内的高温、浑浊空气排出，使室内形成负压区。在负压的“拉力”作用下，室外经过滤降温的洁净空气被“吸入”车间内部，形成“一端送风、一端排风”的定向、稳定的气流组织。这一设计不仅解决了冷风机运行时可能带来的湿度升高问题，更通过高效的气流置换，将车间内的热量、湿气、粉尘等一并带走，实现了整体环境的快速、持续改善。

5、项目成效与价值：

系统启用后，车间内空气流通性显著增强，温湿度得到有效控制。原本闷热、浑浊的生产环境变得清新凉爽，车间温度稳定降低4-8℃。员工工作舒适度大幅提升，生产效率也随之提高。更为关键的是，稳定的温湿度与洁净的空气质量，为3D打印设备的稳定运行和高精度打印创造了理想条件，直接保障了产品品质的稳定性与一致性。

SS-EAC series stainless steel filter air cooler+negative pressure fan comprehensive ventilation and cooling project for a 3D printer manufacturing workshop in Shenzhen

[Project Background]

Shenzhen, located in a subtropical maritime climate zone, has long and high temperature and humidity summers, posing severe challenges to the industrial production environment. As a pioneer city in China's modern intelligent manufacturing industry, Shenzhen has gathered numerous high-precision and cutting-edge enterprises. Among them, 3D printer manufacturing, as a key technology driving the development of Industry 4.0, has extremely strict requirements for the stability and cleanliness of the production environment. Any small fluctuations in temperature and humidity or dust particles in the air can affect the forming accuracy of precision printed components and the yield of final products.

The workshop where this project is located is a standard multi story reinforced concrete structure factory building. The building structure has good airtightness, but the overall area of the workshop is large, with dense personnel and equipment, resulting in serious heat accumulation inside and poor ventilation. An efficient and economical ventilation and cooling plan is urgently needed to improve the working environment and ensure production quality.

Solution Design

After field investigation, the technical team of Ruifeng Environmental Protection Refrigeration comprehensively analyzed the following key factors:

1) Geography and Climate: Shenzhen experiences high temperatures in summer and requires strong cooling capabilities.

2) Industry characteristics: 3D printing has high requirements for air cleanliness and must effectively filter dust.

3) Building structure: The workshop has a large and enclosed area, requiring strong air supply and exhaust systems to form effective airflow organization.

4) Economic considerations: It is necessary to avoid the high energy consumption and investment of traditional industrial air conditioning and seek energy-saving and environmentally friendly solutions.

Based on the above analysis, we have abandoned the traditional air conditioning solution with huge energy consumption and innovatively adopted a comprehensive ventilation and cooling layout that combines high-power stainless steel filtered air fans (SS-EAC series) with negative pressure fans. This combination design is based on the following multiple advantages considerations:

1. One machine dual-use, achieving perfect integration of cleanliness and cooling

This model of equipment integrates two major functions: "air filtration" and "environmental cooling". Outdoor fresh air first passes through a multi-layer filtration system to effectively remove impurities and meet cleanliness requirements; Subsequently, it flows through an efficient wet curtain and uses the physical principle of water evaporation to absorb heat for cooling; Finally, the processed clean cold air is continuously sent into the workshop through a high-power centrifugal fan. Under the hot and dry climate conditions in Shenzhen during summer, the lowest temperature at the air outlet can be reduced to 27-28 ℃, achieving a significant cooling effect.

2. Four level filtration system, accurately meeting cleanliness requirements

In response to the high cleanliness requirements of the 3D printing industry, we have equipped a professional four level filtering system with layers of protection:

1) Protective filter screen: As the first barrier, it effectively intercepts large particles such as sand, rocks, dead branches, and debris, protecting the internal filter screen and core components.

2) Primary filter: Pre filter dust particles with a size of ≥ 5 μ m (such as metal shavings, sawdust, dust, fluff, mosquitoes, etc.) to extend the lifespan of the subsequent filter screen.

3) Medium efficiency filtration layer: performs deep filtration to intercept fine particles with diameters ranging from 1-5 μ m. This configuration is relatively rare among similar products, reflecting our ultimate pursuit of cleanliness.

4) Efficient filtration layer: As the ultimate purification barrier, it can effectively filter submicron particles (≤ 0.3 μ m), including PM2.5, viruses, and bacteria. Its purification standards can reach the level of operating rooms, providing clean assurance for precision manufacturing.

3. Core advantages of the product, creating durability and efficiency

1) Durable and sturdy: The body is made of stainless steel (SS) material, which can be selected as 304 or 316 stainless steel or high zinc galvanized sheet according to needs. It has strong corrosion resistance, adapts to the harsh challenges of industrial environments, and is durable and long-lasting.

2) Efficient cooling: Equipped with a 5090 high-quality wet curtain, it has extremely high water absorption and evaporation efficiency. The four sided air intake design increases the air intake area and cooling efficiency, achieving a significant cooling effect of 4-8 ℃.

3) Intelligent Control: Provides various control systems such as air switches, LCD controllers, and variable frequency controllers to meet the convenient operation and energy-saving needs of different scenarios.

4) Humanized design: The filter layer adopts an insertable design, making it easy and fast to replace the filter element, greatly reducing maintenance costs and time in the later stage.

5) Highly customized: Special air coolers such as explosion-proof and copper iron zinc free models can be customized according to customers' special needs, meeting applications in special scenarios such as chemical engineering and precision electronics.

4. Dual machine collaboration forms a scientific "pull-out" airflow organization

We have also introduced negative pressure fans, which use mechanical force to forcefully expel high-temperature and turbid air from the workshop, creating a negative pressure zone indoors. Under the "pulling force" of negative pressure, clean air that has been filtered and cooled outside is "sucked" into the workshop, forming a directional and stable airflow organization of "one end for air supply and one end for air exhaust". This design not only solves the problem of humidity increase that may occur during the operation of the air cooler, but also efficiently replaces the airflow to take away the heat, moisture, dust, etc. in the workshop, achieving rapid and continuous improvement of the overall environment.

5. Project effectiveness and value:

After the system is activated, the air circulation in the workshop is significantly enhanced, and the temperature and humidity are effectively controlled. The originally stuffy and turbid production environment has become fresh and cool, and the workshop temperature has steadily decreased by 4-8 ℃. The comfort level of employees' work has significantly improved, and production efficiency has also increased accordingly. More importantly, stable temperature and humidity, as well as clean air quality, create ideal conditions for the stable operation and high-precision printing of 3D printing equipment, directly ensuring the stability and consistency of product quality.

Service Capability Expansion

Although this project is a specialized project for the 3D printer manufacturing workshop, the service scope of Ruifeng Environmental Protection Refrigeration is far beyond that. With a deep understanding of the SS-EAC series stainless steel centrifugal air coolers and various ventilation equipment, their applications have widely covered special scenarios such as industry, animal husbandry, communication rooms, data centers, clean rooms, food factories, hospitals, animal husbandry, and desert cities.
