【项目背景与挑战】

在享有“中国低压电气之都”美誉的浙江温州乐清市，电气产业集聚，企业生产环境直接影响产品质量与员工效率。乐清地处东南沿海，属亚热带海洋性季风气候，夏季高温潮湿、闷热多雨，对人员密集、设备集中的生产车间构成严峻挑战。

本次服务的客户是一家专注于低压电气产品生产的企业。此次需要进行环境改善的，是其核心的组装车间。该车间为单层大跨度彩钢框架结构，砖砌墙体，屋顶为隔热彩钢瓦。建筑特点鲜明：空间巨大，挑高超15米；虽有少量玻璃窗，采光不佳，但整体密封性较强。车间内，生产工艺复杂，人员密集，机器设备持续运转，导致内部热量、废气积聚，空气质量与热舒适度成为影响生产效率和员工体验的关键瓶颈。

【瑞峰方案：精准设计，因地制宜】

面对这一复杂的车间环境，瑞峰环保制冷的方案设计团队深入现场，综合考量了多项关键因素：

1、地理与气候因素： 针对乐清夏季高温高湿的气候特点，需引入大量新风，以有效降温并带走室内湿浊空气。

2、建筑结构因素： 针对15米超高挑高及密封性强的建筑特点，需采用远距离送风方式，确保冷气能有效下沉至工作区域，同时避免冷量浪费。

3、生产工艺因素： 低压电气组装对空气洁净度有一定要求，需避免直接吹风导致灰尘扬起，同时需保证设备运行环境相对稳定。

4、人员密集因素： 需为密集作业的员工提供均匀、柔和、舒适的降温气流，避免局部过冷或过热，提升工作满意度。

基于以上综合分析，我们为该项目量身定制了 “大风量离心式冷风机 + 长风管均匀送风” 的组合设计方案。

【方案亮点与工作原理】

1、设备选型： 采用大风量离心式冷风机。该设备通过离心风机的高静压特性，能将室外新鲜空气经风机内水帘过滤、降温处理后，产生强劲、可远距离输送的冷气流。

2、安装方式： 所有冷风机均安装在车间屋顶钢结构上，彻底释放了宝贵的室内地面空间，不影响生产设备布局与物料流转。

3、气流组织： 我们设计了间隔均匀的风管系统贯穿车间屋顶，风管垂直向下延伸至离地面约5米的工人作业高度，末端安装水平四向出风的风动百叶窗。这种设计巧妙利用了冷空气自然下沉的物理特性，同时通过四向送风，将冷气均匀、柔和地覆盖至整个车间区域的每一个角落。

【环境改善与综合效益】

方案实施后，车间环境发生了质的飞跃：

1、物理原理应用： 冷风机持续送入大量经过处理的冷空气，在车间内形成稳定的微正压环境。源源不断的冷气在重力作用下自然下沉，有效“包裹”作业区域，同时将人员、设备产生的热气、粉尘和浑浊空气通过门窗缝隙挤压排出室外，实现空气的快速置换与降温。

2、体感舒适度提升： 员工不再处于闷热环境中，均匀柔和的冷气流显著降低了体感温度，疲劳感减轻，工作专注度与满意度大幅提升。

3、设备运行稳定： 车间温度的有效控制，也保障了精密组装设备、检测仪器在适宜的温度环境下稳定运行，降低了故障率，间接保障了产品质量与生产效率。

Project Background and Challenges

In Yueqing City, Wenzhou, Zhejiang Province, which enjoys the reputation of "China's Low Voltage Electrical Capital", the electrical industry gathers, and the production environment of enterprises directly affects product quality and employee efficiency. Yueqing is located on the southeast coast and has a subtropical maritime monsoon climate. In summer, it is hot, humid, stuffy, and rainy, posing a severe challenge to production workshops with dense personnel and concentrated equipment.

The client of this service is an enterprise specializing in the production of low-voltage electrical products. The core assembly workshop requires environmental improvement this time. The workshop is a single-layer large-span color steel frame structure, with brick walls and a roof made of insulated color steel tiles. Distinctive architectural features: huge space with a height of 15 meters; Although there are a few glass windows with poor lighting, the overall sealing is strong. In the workshop, the production process is complex, personnel are dense, and machinery and equipment continue to operate, resulting in the accumulation of internal heat and exhaust gas. Air quality and thermal comfort have become key bottlenecks affecting production efficiency and employee experience.

Ruifeng Plan: Precise Design, Tailored to Local Conditions

Faced with this complex workshop environment, the design team of Ruifeng Environmental Protection Refrigeration went deep into the site and comprehensively considered multiple key factors:

1. Geographical and climatic factors: In response to the high temperature and humidity climate characteristics of Yueqing in summer, it is necessary to introduce a large amount of fresh air to effectively cool down and remove indoor humid air.

2. Architectural structural factors: In response to the characteristics of a building with a height of 15 meters and strong sealing, it is necessary to adopt a long-distance air supply method to ensure that the cold air can effectively sink into the work area and avoid wasting cooling capacity.

3. Production process factors: Low voltage electrical assembly has certain requirements for air cleanliness, and it is necessary to avoid direct blowing that may cause dust to rise. At the same time, it is necessary to ensure a relatively stable operating environment for the equipment.

4. Personnel density factor: It is necessary to provide uniform, soft, and comfortable cooling airflow for employees engaged in intensive operations to avoid local overcooling or overheating and improve job satisfaction.

Based on the above comprehensive analysis, we have tailored a combination design scheme of "high air volume centrifugal air cooler+long air duct uniform air supply" for this project.

[Program Highlights and Working Principle]

1. Equipment selection: Adopt high air volume centrifugal air cooler. This device utilizes the high static pressure characteristics of a centrifugal fan to filter and cool outdoor fresh air through the water curtain inside the fan, generating a strong and long-distance cold air flow.

2. Installation method: All air coolers are installed on the steel structure of the workshop roof, completely freeing up valuable indoor floor space without affecting the layout of production equipment and material flow.

3. Airflow organization: We have designed a uniformly spaced air duct system that runs through the workshop roof. The air ducts extend vertically downwards to a worker working height of about 5 meters above the ground, and horizontal four-way air outlet louvers are installed at the end. This design cleverly utilizes the physical characteristics of natural sinking of cold air, while evenly and gently covering every corner of the entire workshop area through four-way air supply.

Environmental Improvement and Comprehensive Benefits

After the implementation of the plan, there was a qualitative leap in the workshop environment:

1. Application of physical principles: The air cooler continuously delivers a large amount of processed cold air, creating a stable micro positive pressure environment in the workshop. The continuous flow of cold air naturally sinks under the action of gravity, effectively "wrapping" the work area, while squeezing out the hot air, dust, and turbid air generated by personnel and equipment through the gaps between doors and windows, achieving rapid air replacement and cooling.

2. Improved perceived comfort: Employees are no longer in a hot and humid environment, and the uniform and soft air flow significantly reduces perceived temperature, reduces fatigue, and greatly improves work focus and satisfaction.

3. Stable equipment operation: The effective control of workshop temperature also ensures the stable operation of precision assembly equipment and testing instruments in suitable temperature environments, reducing failure rates and indirectly guaranteeing product quality and production efficiency.

Experience and Ability

Although this project is aimed at the assembly workshop of low-voltage electrical enterprises, the successful implementation of its solution fully demonstrates the profound accumulation of Ruifeng Environmental Protection Refrigeration in the field of ventilation and cooling in similar large space, high height, and high-density crowd operation scenarios (such as large-scale warehousing, mechanical processing, shoe and clothing, food packaging, etc.).

We not only have efficient equipment, but also professional solution design capabilities and flexible engineering implementation experience. Faced with any complex large space environment, we can combine on-site reality to scientifically select equipment and layout systems, and tailor the most economical, comfortable, and energy-saving ventilation and cooling solutions for customers.
