【项目名称】 苏南某液压件厂生产车间——离心式冷风机+长风管定向送风组合工程

【项目背景与挑战】

该企业坐落于中国经济最活跃的地区之一——长三角产业带南部的苏南地区。此区域属亚热带湿润气候，四季分明，夏季高温高湿，冬季湿冷，对工业车间的通风降温提出了较高要求。长三角地区作为我国重要的制造业基地，液压产业发达，对生产环境的稳定性要求极高。液压件生产（特别是金属加工和塑料成型）过程中，设备运行会产生大量热量、油雾及粉尘，若不能及时有效排出，不仅影响一线员工的体感舒适度与工作效率，更可能因温度、湿度的波动对液压、冲压等精密设备的加工精度和运行稳定性造成不利影响。

此次改造的车间为典型的大跨度单层建筑：彩钢框架结构，砖砌墙体，隔热彩钢瓦屋顶，并配有大面积玻璃窗。 其特点是建筑面积大、空间挑高、采光良好但整体密封性一般。由于生产工艺的特殊性，车间内部空气质量欠佳。但值得庆幸的是，车间内无行车设备，顶部空间开阔、无障碍物，这为进行定点、定向的岗位送风布局提供了得天独厚的条件。

【方案设计与实施】

面对车间的多重挑战，瑞峰环保制冷的方案设计团队进行了深入细致的现场勘察与综合考量。我们不仅分析了长三角地区特有的高温高湿气候对车间内部环境的影响，还充分结合了车间现有的建筑结构特点、生产工艺布局、人员作业区域以及顶部净空条件，力求方案的精准与高效。

基于以上分析，我们创新性地提出了“大风量离心式冷风机+长风管均匀送风”的组合方案，具体实施如下：

1、设备选型与布局： 我们将大风量离心式冷风机安装于建筑墙体外侧。这种设计不仅彻底释放了宝贵的室内生产面积，更利用离心风机风压大、送风距离远的特点，将经过降温过滤的新鲜空气强力送入车间内部。

2、气流组织设计： 我们利用车间顶部开阔的空间，巧妙吊挂安装定制化的长风管系统。风管上按岗位需求开设科学分布的送风口，将冷气精准、均匀地输送至每一位操作人员的工作岗位，形成有效的“岗位微气候”。

3、系统协同增效： 该系统运行时，冷风机源源不断注入的新风在车间内形成微正压环境。这股持续流动的凉爽、洁净空气，不仅能有效稀释并驱散设备产生的热气、油雾及浊气，将其从窗户或缝隙挤出室外，更极大地提升了员工的体感舒适度，同时为液压机、冲压机等设备提供了更稳定的运行环境温湿度，间接保障了产品的加工精度与设备的运行寿命。

【灵活调整与优化】

瑞峰团队的专业不仅体现在前期规划，更在于对实际效果的精准把控。项目深入勘察与测算后，我们发现仅依靠冷风机产生的微正压，在车间局部通风死角或产热量极大区域，主动排气能力稍显不足。为此，我们迅速做出优化调整：在方案中补充增加了与车间换气次数需求相匹配的负压风机，形成“一送一排”的黄金组合。负压风机的主动抽吸，加速了室内热气和浊气的排出，确保了整个车间空气流通的快速与彻底，使降温通风效果达到最优。

【项目总结与延伸】

此次苏南液压件厂项目的成功实施，再次印证了瑞峰环保制冷在复杂工业环境通风降温领域的深厚实力。虽然服务对象是液压件制造企业，但其所面临的高温、油雾、大空间、人员密集等环境痛点，在机械加工、铸造、汽车零部件、塑料制品等众多行业的大跨度车间中普遍存在。

本项目充分展示了瑞峰公司具备以下核心能力：

1、综合性设备选型能力： 能够根据客户实际情况，灵活组合“离心风机+长风管”、“负压风机”等多种设备，而非单一产品推销。

2、深度方案设计能力： 不仅考虑降温，更综合考量建筑结构、地理气候、生产工艺与人员舒适度。

3、动态工况调整能力： 具备严谨的专业测算与灵活应变的现场优化能力，确保最终效果超越客户预期。

选择瑞峰，就是选择专业、可靠、为您量身定制的通风降温解决方案。

[Project Name] Production Workshop of a Hydraulic Parts Factory in Sunan - Centrifugal Air Cooler+Long Duct Directional Air Supply Combination Project

Project Background and Challenges

The enterprise is located in the southern part of the Yangtze River Delta industrial belt, which is one of the most active regions in China's economy. This area belongs to a subtropical humid climate with distinct four seasons. The summer is hot and humid, while the winter is wet and cold, which places high demands on ventilation and cooling in industrial workshops. As an important manufacturing base in China, the Yangtze River Delta region has a developed hydraulic industry and requires extremely high stability in the production environment. During the production of hydraulic components (especially metal processing and plastic molding), equipment operation generates a large amount of heat, oil mist, and dust. If they cannot be effectively discharged in a timely manner, it not only affects the physical comfort and work efficiency of frontline employees, but also may have adverse effects on the machining accuracy and operational stability of precision equipment such as hydraulic and stamping due to temperature and humidity fluctuations.

The workshop renovated this time is a typical large-span single-layer building: color steel frame structure, brick walls, insulated color steel tile roof, and equipped with large area glass windows. Its characteristics are large building area, high space, good lighting, but overall sealing is average. Due to the particularity of the production process, the air quality inside the workshop is poor. Fortunately, there are no driving equipment in the workshop, and the top space is spacious and obstacle free, which provides unique conditions for the layout of fixed-point and directional post air supply.

[Scheme Design and Implementation]

Faced with multiple challenges in the workshop, the design team of Ruifeng Environmental Protection Refrigeration conducted in-depth and detailed on-site investigations and comprehensive considerations. We not only analyzed the impact of the unique high temperature and high humidity climate in the Yangtze River Delta region on the internal environment of the workshop, but also fully combined the existing building structure characteristics, production process layout, personnel operation area, and top clearance conditions of the workshop, striving for the accuracy and efficiency of the plan.

Based on the above analysis, we have innovatively proposed a combination scheme of "high air volume centrifugal air cooler+long air duct uniform air supply", which is implemented as follows:

1. Equipment selection and layout: We will install high air volume centrifugal air coolers on the outside of building walls. This design not only completely releases valuable indoor production area, but also utilizes the characteristics of high air pressure and long air supply distance of centrifugal fans to forcefully send fresh air that has been cooled and filtered into the workshop.

2. Airflow organization design: We utilize the open space at the top of the workshop to cleverly hang and install customized long air duct systems. Scientifically distributed air supply outlets are set up on the air duct according to job requirements, delivering cold air accurately and evenly to each operator's work position, forming an effective "job microclimate".

3. System synergy: When the system is running, the continuous injection of fresh air from the air cooler creates a micro positive pressure environment in the workshop. This continuous flow of cool and clean air not only effectively dilutes and disperses the hot air, oil mist, and turbidity generated by the equipment, squeezing them out of windows or gaps, but also greatly improves the comfort of employees. At the same time, it provides a more stable operating environment temperature and humidity for equipment such as hydraulic presses and stamping machines, indirectly ensuring the processing accuracy of products and the service life of equipment.

Flexible adjustment and optimization

The professionalism of the Ruifeng team is not only reflected in the early planning, but also in the precise control of the actual results. After in-depth investigation and calculation of the project, we found that relying solely on the micro positive pressure generated by the air cooler resulted in slightly insufficient active exhaust capacity in areas with poor ventilation or high heat generation in the workshop. To this end, we quickly made optimization adjustments: we added negative pressure fans that matched the workshop's ventilation requirements to the plan, forming a golden combination of "one supply, one row". The active suction of the negative pressure fan accelerates the discharge of indoor hot and humid air, ensuring fast and thorough air circulation throughout the workshop, and achieving optimal cooling and ventilation effects.

Project Summary and Extension

The successful implementation of the Sunan Hydraulic Parts Factory project once again confirms the profound strength of Ruifeng Environmental Protection Refrigeration in the field of ventilation and cooling in complex industrial environments. Although the service target is hydraulic component manufacturing enterprises, the environmental pain points they face, such as high temperature, oil mist, large space, and dense personnel, are commonly present in large-span workshops in many industries such as mechanical processing, casting, automotive parts, and plastic products.

This project fully demonstrates that Ruifeng Company possesses the following core capabilities:

1. Comprehensive equipment selection capability: able to flexibly combine multiple devices such as "centrifugal fan+long air duct" and "negative pressure fan" according to the actual situation of customers, rather than promoting a single product.

2. Deep scheme design capability: not only considering cooling, but also comprehensively considering building structure, geographical climate, production technology, and personnel comfort.

3. Dynamic working condition adjustment capability: With rigorous professional calculations and flexible on-site optimization capabilities, we ensure that the final results exceed customer expectations.

Choosing Ruifeng means choosing a professional, reliable, and tailor-made ventilation and cooling solution for you.
