【项目背景与地域特色】

该工程项目位于素有“稀土王国”美誉的江西省赣州市。赣州地处中亚热带南缘，属典型的亚热带季风湿润气候，其特征是四季分明、湿度较大、夏季漫长且高温高热。年平均气温在19℃左右，而夏季极端气温时常攀升至35℃以上，且伴随高湿度的“桑拿天”，对工业生产的散热和作业人员的舒适度构成了严峻挑战。

赣州不仅是江西省域副中心城市，更是全国重要的稀土资源开采及深加工基地。依托丰富的稀土储量，该地区已形成从稀土开采、分离冶炼到永磁材料、发光材料等高端应用的完整产业链。本次服务的客户，正是这一产业链中专注于磁性材料精加工的关键一环。磁性材料（如钕铁硼）因其高剩磁、高矫顽力等特点，被广泛应用于新能源、航空航天及电子元器件领域，其加工精度对车间环境有着较高要求。

【现场工况与挑战】

客户的生产车间位于新建的多层钢筋混凝土标准厂房内，具有单层面积大、层高普遍较高的建筑特点。在磁性材料精加工过程中，通常包含切片、磨削、倒角、打孔等工序。这些工序不仅会产生细微的粉尘颗粒，同时高速运转的机械设备（如线切割机、磨床）也会释放大量热量，导致车间内部温度累积升高。

若采用传统中央空调方案，面对如此巨大的空间容积，不仅前期设备投入成本高昂，后期的电费损耗也让企业难以承受。因此，如何在控制成本的前提下，有效解决高温、异味及空气流通问题，成为本次方案设计的核心难点。

【瑞峰解决方案与设计亮点】

针对客户的实际痛点，瑞峰环保制冷的方案设计团队综合考量了地理气候特征（高温高湿需强通风）、建筑结构（高大空间难密封）、生产工艺（产热产尘）以及场地利用率（不占用宝贵生产空间） 等四大核心因素，量身定制了一套“蒸发式降温为主、负压排风为辅、移动式补位”的综合治理方案：

1、外挂式大风量送风系统（主体降温）：

为不占用车间内宝贵的作业及设备摆放空间，我们将蒸发式冷风机（环保空调） 巧妙地安装在车间外墙外侧。利用水蒸发吸热的物理原理——当干热的空气穿过湿润的湿帘时，水分吸收空气中的热量发生汽化，从而降低空气温度（通常在江西夏季可降温4℃-10℃）。处理后的冷风通过铺设的专用风管，源源不断地输送到车间深处，形成有效的“冷空气湖”，覆盖员工主要的工作岗位。

2、负压强制排风系统（空气质量控制）：

在产生明显异味和热量聚集的特定车间（如烧结或打磨区），我们经过专业的风量平衡计算，安装了足够数量的负压风机。这些风机在运行时，会在车间内形成负压区，迫使室外的空气通过门窗或进风口流入，从而在极短时间内（通常1-3分钟）完成整室换气，迅速抽走漂浮的粉尘、烟雾以及机械产生的余热，保持车间空气清新。

3、移动式精准降温（灵活补位）：

针对车间内人员不固定的巡视点或零星作业区，我们配备了移动式冷风机。这类设备采用“人机合一”的理念，底部装有万向轮，可灵活推至任何需要降温的工作点。其工作原理同样是利用循环水冷却，但更侧重于局部空间的即时降温，做到“人在机在，人走机移”，极大提高了设备的利用率和投资回报率。

【施工成效与客户价值】

工程竣工后，车间环境得到了质的飞跃：

1、体感舒适度提升： 原本闷热难耐的作业区变得清风习习，体感温度显著下降，员工因高温导致的中暑风险和疲惫感大幅降低，工作专注度明显提高。

2、生产稳定性增强： 环境温度的均衡控制，有助于加工设备（如高精度磨床）的热稳定性，减少了因热胀冷缩导致的设备精度误差，保障了磁性材料切割与打磨的产品优良率。

3、空气洁净度改善： 负压系统的强力排风，有效降低了车间内的粉尘浓度，不仅保护了员工呼吸健康，也减少了粉尘对精密机械轴承的磨损。

【经验总结与能力拓展】

此次赣州磁性材料精加工车间的通风降温工程，虽然针对的是“稀土深加工”这一特定细分领域，但其高温、高湿、大空间、产尘产热的工况特征，在陶瓷生产、重型机械加工、大型注塑车间乃至物流仓储等场景中具有极高的普适性与参考价值。

瑞峰环保制冷通过此次项目，再次验证了我们面对“高大空间综合治理”的硬实力。我们不拘泥于单一产品，而是善于综合选型，将固定式冷风机、负压排风系统、移动式设备有机组合，通过精准的风道设计与气流组织计算，用最低的能耗成本，为客户量身打造最适合的通风降温解决方案。

Project Background and Regional Characteristics

The project is located in Ganzhou City, Jiangxi Province, known as the "Rare Earth Kingdom". Ganzhou is located on the southern edge of the subtropical zone and belongs to a typical subtropical monsoon humid climate. Its characteristics are distinct four seasons, high humidity, long summers, and high temperatures. The annual average temperature is around 19 ℃, while extreme temperatures in summer often climb above 35 ℃, accompanied by high humidity "sauna days", posing a serious challenge to the heat dissipation of industrial production and the comfort of workers.

Ganzhou is not only a sub central city in Jiangxi Province, but also an important base for rare earth resource mining and deep processing in the country. Relying on abundant rare earth reserves, the region has formed a complete industrial chain from rare earth mining, separation and smelting to high-end applications such as permanent magnet materials and luminescent materials. The customer of this service is a key link in this industry chain that focuses on precision machining of magnetic materials. Magnetic materials such as neodymium iron boron are widely used in the fields of new energy, aerospace, and electronic components due to their high remanence, high coercivity, and other characteristics. Their processing accuracy has high requirements for the workshop environment.

On site working conditions and challenges

The customer's production workshop is located in a newly built multi story reinforced concrete standard factory building, which has the characteristics of large single story area and generally high floor height. In the precision machining process of magnetic materials, it usually includes processes such as slicing, grinding, chamfering, and punching. These processes not only generate fine dust particles, but also high-speed mechanical equipment (such as wire cutting machines, grinders) release a large amount of heat, leading to an accumulated increase in temperature inside the workshop.

If traditional central air conditioning solutions are adopted, facing such a huge space volume, not only will the initial equipment investment cost be high, but the later electricity consumption will also be difficult for enterprises to bear. Therefore, how to effectively solve the problems of high temperature, odor, and air circulation while controlling costs has become the core difficulty of this scheme design.

Ruifeng Solution and Design Highlights

In response to the actual pain points of customers, the design team of Ruifeng Environmental Protection Refrigeration has comprehensively considered four core factors: geographical climate characteristics (high temperature and high humidity require strong ventilation), building structure (tall spaces are difficult to seal), production process (heat and dust generation), and site utilization rate (not occupying valuable production space). They have tailored a comprehensive management plan that focuses on evaporative cooling, negative pressure exhaust as a supplement, and mobile positioning

1. External high air volume supply system (main cooling):

To avoid occupying valuable workspace and equipment placement space in the workshop, we ingeniously installed evaporative air coolers (environmentally friendly air conditioners) on the outside of the workshop walls. The physical principle of using water evaporation to absorb heat - when dry and hot air passes through a moist curtain, moisture absorbs heat from the air and vaporizes, thereby reducing the air temperature (usually dropping by 4 ℃ -10 ℃ in summer in Jiangxi). The processed cold air is continuously transported to the depths of the workshop through dedicated air ducts, forming an effective "cold air lake" that covers the main job positions of employees.

2. Negative pressure forced exhaust system (air quality control):

In specific workshops that produce noticeable odors and heat accumulation, such as sintering or polishing areas, we have installed a sufficient number of negative pressure fans through professional air volume balancing calculations. When these fans are in operation, they create a negative pressure zone in the workshop, forcing outdoor air to flow in through doors, windows, or air intakes, thus completing the entire room ventilation in a very short time (usually 1-3 minutes), quickly removing floating dust, smoke, and residual heat generated by machinery, and keeping the workshop air fresh.

3. Mobile precision cooling (flexible positioning):

We have equipped mobile air coolers for non fixed inspection points or sporadic work areas in the workshop. This type of equipment adopts the concept of "human-machine integration" and is equipped with universal wheels at the bottom, which can be flexibly pushed to any working point that requires cooling. Its working principle is also to use circulating water cooling, but it focuses more on immediate cooling of local spaces, achieving the principle of "people in the machine, people moving the machine", greatly improving the utilization rate and return on investment of the equipment.

Construction effectiveness and customer value

After the completion of the project, the workshop environment has undergone a qualitative leap:

1. Improved physical comfort: The previously hot and stuffy work area has become cool and comfortable, with a significant decrease in perceived temperature. Employees' risk of heatstroke and fatigue caused by high temperatures have been greatly reduced, and their work focus has been significantly improved.

2. Enhanced production stability: Balanced control of environmental temperature helps to improve the thermal stability of processing equipment (such as high-precision grinding machines), reducing equipment accuracy errors caused by thermal expansion and contraction, and ensuring the high yield of magnetic material cutting and polishing products.

3. Improvement of air cleanliness: The strong exhaust of the negative pressure system effectively reduces the dust concentration in the workshop, not only protecting the respiratory health of employees, but also reducing the wear of precision mechanical bearings caused by dust.

Experience Summary and Ability Expansion

The ventilation and cooling project of the Ganzhou magnetic material precision processing workshop, although targeted at the specific sub field of "rare earth deep processing", has high universality and reference value in scenarios such as ceramic production, heavy machinery processing, large-scale injection molding workshops, and logistics warehousing due to its high temperature, high humidity, large space, and dust and heat generation characteristics.

Through this project, Ruifeng Environmental Protection Refrigeration has once again verified our hard power in the face of "comprehensive management of high-rise spaces". We are not limited to a single product, but are good at comprehensive selection, combining fixed air coolers, negative pressure exhaust systems, and mobile devices organically. Through precise air duct design and airflow organization calculation, we tailor the most suitable ventilation and cooling solutions for customers with the lowest energy consumption cost.
