一、项目背景

该精密机械厂位于温州永嘉，地处浙南沿海，属亚热带季风气候区，四季分明，夏季炎热潮湿，最高气温可达35℃以上，湿度常年偏高；冬季温和少雪，偶有低温寒潮。高温高湿环境对精密加工设备的稳定性与产品质量构成显著挑战，厂房环境控制成为保障生产效能的关键环节。

该企业专注于高精度机械零部件加工，核心设备为多台CNC数控机床。CNC机床通过计算机程序控制精密切削，对温度、湿度及粉尘极为敏感：环境温度波动易导致金属部件热胀冷缩，影响加工精度；湿度过高可能引发设备锈蚀与电路故障；切削过程中产生的油雾与粉尘则会附着于设备与产品表面，降低工艺质量。因此，维持车间恒温、低湿、洁净的空气环境，是保障设备长效运行与产品合格率的重要基础。

厂区为标准化钢筋混凝土结构厂房，墙面设有大面积采光玻璃窗，密封性较好，适合采用内循环气流组织形式的环境控制方案。

二、瑞峰解决方案

瑞峰环保制冷技术团队综合多项因素进行方案设计：

1、地理气候特征：针对永嘉地区夏季高温高湿、冬季湿冷的特点，方案需兼顾降温、除湿与通风功能；

2、厂房结构特性：厂房密封性良好，适合采用内循环空气处理模式，减少外部不稳定气候对室内环境的影响；

3、车间工艺需求：CNC加工过程中产生油雾与粉尘，要求通风系统具备较强的空气置换与净化能力；

4、气流组织要求：车间空间开阔、设备布局分散，送风距离远，需选用射流式机型实现远距离定向送风，确保气流均匀覆盖工作区域。

经综合分析，瑞峰为该车间设计并实施大功率立式射流省电工业空调系统。该机型凭借强力射流技术，实现远距离、高风速送风，有效打破空间温度分层，促进全车间空气循环；同时具备高效过滤模块，可吸附空气中细微粉尘与油雾粒子，改善车间空气质量；其内置的省电模式与智能温控系统，能够在满足工艺温湿度要求的前提下，显著降低运行能耗。

三、实施效果

系统安装调试完成后，车间环境得到显著改善：

1、温湿度稳定控制在工艺要求范围内，夏季车间温度保持在26-28℃，相对湿度低于60%；

2、射流送风有效覆盖全部加工区域，无气流死角，员工体感舒适度大幅提升；

3、空气流通加强后，油雾与粉尘浓度明显下降，设备表面洁净度提高，维护周期延长；

4、能效表现优异，相比传统通风降温方案，节能率达到30%以上，获得厂方高度认可。

四、项目意义

本案例虽是针对机加工车间的环境改造，但其技术方案同样适用于其他具有空间开阔、发热设备集中、空气质量要求高、送风距离远等特点的工业场景，如焊接车间、电子装配车间、仓储物流中心等。瑞峰团队凭借在气流组织设计、环境适应性评估与专业化安装方面的综合能力，持续为各行业提供精准、高效、节能的车间环境解决方案。

1、 Project Background

The precision machinery factory is located in Yongjia, Wenzhou, along the southern coast of Zhejiang Province. It belongs to the subtropical monsoon climate zone, with distinct four seasons. The summer is hot and humid, with the highest temperature reaching over 35 ℃, and the humidity is consistently high; Winter is mild with little snow and occasional cold waves. The high temperature and high humidity environment pose significant challenges to the stability and product quality of precision machining equipment, and factory environment control has become a key link in ensuring production efficiency.

This enterprise focuses on high-precision machining of mechanical components, with multiple CNC machine tools as its core equipment. CNC machine tools control precision cutting through computer programs and are extremely sensitive to temperature, humidity, and dust. Environmental temperature fluctuations can easily cause thermal expansion and contraction of metal parts, affecting machining accuracy; Excessive humidity may cause equipment corrosion and circuit failure; The oil mist and dust generated during the cutting process will adhere to the surfaces of equipment and products, reducing the quality of the process. Therefore, maintaining a constant temperature, low humidity, and clean air environment in the workshop is an important foundation for ensuring the long-term operation of equipment and product qualification rate.

The factory area is a standardized reinforced concrete structure factory building with large areas of skylight glass windows on the walls, which have good sealing and are suitable for environmental control schemes using internal circulation airflow organization.

2、 Ruifeng Solution

The Ruifeng Environmental Protection Refrigeration Technology Team has designed a comprehensive plan based on multiple factors:

(1). Geographical and climatic characteristics: In response to the high temperature and humidity in summer and wet and cold in winter in Yongjia area, the plan needs to take into account cooling, dehumidification, and ventilation functions;

(2). Structural characteristics of the factory building: The factory building has good sealing and is suitable for using internal circulation air treatment mode to reduce the impact of external unstable climate on the indoor environment;

(3). Workshop process requirements: Oil mist and dust are generated during CNC machining, and the ventilation system is required to have strong air displacement and purification capabilities;

(4). Airflow organization requirements: The workshop space is spacious, the equipment layout is scattered, and the air supply distance is far. Jet type models need to be selected to achieve long-distance directional air supply, ensuring that the airflow covers the work area evenly.

After comprehensive analysis, Ruifeng designed and implemented a high-power vertical jet energy-saving industrial air conditioning system for the workshop. This model utilizes strong jet technology to achieve long-distance, high wind speed air supply, effectively breaking down temperature stratification in the space and promoting air circulation throughout the workshop; Simultaneously equipped with efficient filtering modules, it can adsorb fine dust and oil mist particles in the air, improving the air quality in the workshop; Its built-in power-saving mode and intelligent temperature control system can significantly reduce operating energy consumption while meeting the requirements of process temperature and humidity.

3、 Implementation effect

After the system installation and debugging were completed, the workshop environment was significantly improved:

(1). Stable control of temperature and humidity within the required process range, with workshop temperature maintained at 26-28 ℃ and relative humidity below 60% in summer;

(2). Jet air supply effectively covers the entire processing area, with no dead corners of airflow, greatly improving employee comfort;

(3). After strengthening air circulation, the concentration of oil mist and dust significantly decreased, the surface cleanliness of equipment improved, and the maintenance cycle was extended;

(4). Excellent energy efficiency performance, with an energy-saving rate of over 30% compared to traditional ventilation and cooling solutions, highly recognized by the factory.

4、 Project significance

Although this case is aimed at the environmental renovation of machining workshops, its technical solution is also applicable to other industrial scenarios with open spaces, concentrated heating equipment, high air quality requirements, and long air supply distances, such as welding workshops, electronic assembly workshops, warehousing and logistics centers, etc. The Ruifeng team, with its comprehensive capabilities in airflow organization design, environmental adaptability assessment, and specialized installation, continues to provide precise, efficient, and energy-saving workshop environmental solutions for various industries.
