【项目背景与客户需求】

本次项目客户位于湖南省岳阳市，是一家专业生产各类普通钓具及高端碳纤维钓具的现代化制造企业。

1、地理与产业分析：

岳阳地处长江中游，属于典型的亚热带季风湿润气候，夏季高温高湿且持续时间长，极端气温常突破35℃，闷热天气对高强度生产作业极为不利。作为湖南的“北大门”，岳阳依托通江达海的地理优势，形成了成熟的渔具制造产业集群，尤其以碳纤维钓具为代表的高端制造业发展迅猛。该产业的聚集效应使得生产环境的标准成为了企业竞争力的关键一环。

2、钓具生产特性：

客户主要生产钓竿、渔轮等产品。以碳纤维钓竿为例，其生产工艺涉及裁布、卷制、固化、研磨、涂装等多道工序。

3、生产痛点： 环氧树脂固化过程中会产生异味和微量热量；研磨工序则会产生极细的粉尘；涂装车间对空气洁净度有较高要求。若车间通风不畅，高温、粉尘和异味积聚不仅影响一线作业人员的体感舒适度与工作效率，更可能附着于半成品表面，导致涂装瑕疵、粘合不牢等品质问题。

【厂房现状与挑战】

该厂房为五层钢筋混凝土结构标准厂房，每层层高适中，采光良好。但主要面临三大挑战：

1、多层结构热压效应： 多层建筑中，热空气上升导致顶层温度远高于底层，形成“蒸笼效应”。

2、密闭性与散热矛盾： 标准厂房虽采光好，但窗户开启面积有限，自然通风无法满足大面积、高强度的散热排尘需求。

3、空间利用率要求： 生产线布局紧凑，任何通风设备都不能占用宝贵的室内地面作业面积。

【瑞峰方案：蒸发式冷风机+负压风机组合系统】

针对上述难点，瑞峰环保制冷技术团队结合地理气候特征、厂房多层结构、生产工艺要求三大核心因素，量身定制了“蒸发式冷风机岗位送风+负压风机整体排风”的组合式通风降温方案。

设备布局与工作原理：

1、蒸发式冷风机（安装在墙体/屋顶）： 利用岳阳夏季“干湿球温度差”较大的气候特点（这也是蒸发降温效果最好的时节），我们将冷风机安装在建筑外墙或屋顶。设备汲取室外新鲜空气，通过“水蒸发吸热”这一自然物理原理，将空气温度降低4-10℃后，通过铺设的送风管道精准引入室内。这种设计零占用室内地面面积，彻底解决了多层厂房空间紧张的问题。

2、负压风机（安装在对侧墙体）： 在车间另一侧或顶层安装大流量负压风机，强制将室内人员密集区散发的热气、设备运行的余热以及固化、研磨工序产生的浊气、异味迅速排出室外。

综合运用的物理原理与环境改善：

这一设计构建了“进+排”的完整空气对流系统，形成室内负压状态，迫使室外新鲜空气经冷风机降温后，如同无形的活塞般均匀流经整个车间，实现每小时数十次甚至上百次的空气置换。

1、体感舒适度提升： 持续的低温新风带走员工体表汗液，实现“降温不吹人”的清爽体感，大幅降低中暑风险，提升留岗率。

2、产品品质保障： 快速排走研磨粉尘和固化异味，保证了高端碳纤维制品涂装面的光洁度与粘合强度，有效降低了产品不良率。

3、空气环境健康： 引入富氧新风，稀释车间内的空气污染物浓度，为员工创造一个真正健康、绿色的工作环境。

【项目价值与能力延伸】

此次岳阳钓具厂项目的成功实施，再次印证了瑞峰环保制冷在工程方案设计与通风降温领域的专业实力。

1、业务场景的相似性与延展性：

虽然这是一个钓具厂案例，但其所面临的高温、异味、粉尘问题，以及多层建筑结构的通风难点，与电子装配、食品加工、制衣纺织、仓储物流等行业场景高度相似。无论是需要洁净的涂装车间，还是需要散热的密集型劳动车间，瑞峰都能提供精准的解决方案。

2、核心能力体现：

本项目充分展现了瑞峰团队对多层空间气流组织的深刻理解，以及在设备综合选型与方案设计上的精细化施工能力。我们不仅提供设备，更提供针对复杂建筑结构的“顶层排热、中间层引流、底层送风”的立体化通风设计。

选择瑞峰，让您的车间告别闷热，拥抱清新高效的生产力！

Project Background and Customer Requirements

The client of this project is located in Yueyang City, Hunan Province, and is a modern manufacturing enterprise specializing in the production of various types of ordinary fishing gear and high-end carbon fiber fishing gear.

1. Geographic and Industrial Analysis:

Yueyang is located in the middle reaches of the Yangtze River and belongs to a typical subtropical monsoon humid climate. The summer is characterized by high temperatures and high humidity, and the duration is long. Extreme temperatures often exceed 35 ℃, and the hot and humid weather is extremely unfavorable for high-intensity production operations. As the "northern gateway" of Hunan, Yueyang has formed a mature fishing gear manufacturing industry cluster relying on its geographical advantages of connecting rivers and reaching the sea, especially the high-end manufacturing industry represented by carbon fiber fishing gear is developing rapidly. The agglomeration effect of this industry makes the standard of production environment a key factor in the competitiveness of enterprises.

2. Production characteristics of fishing gear:

The customer mainly produces fishing rods, fishing wheels and other products. Taking carbon fiber fishing rods as an example, their production process involves multiple steps such as cutting, rolling, curing, grinding, and coating.

3. Production pain points: During the curing process of epoxy resin, there will be odors and trace amounts of heat; The grinding process will generate extremely fine dust; The painting workshop has high requirements for air cleanliness. If the ventilation in the workshop is poor, the accumulation of high temperature, dust, and odors not only affects the physical comfort and work efficiency of frontline workers, but also may adhere to the surface of semi-finished products, leading to quality problems such as coating defects and weak adhesion.

The current situation and challenges of the factory building

The factory building is a five story reinforced concrete structure standard factory building, with each floor of moderate height and good lighting. But it mainly faces three major challenges:

1. Multi story structure thermal pressure effect: In multi story buildings, the rise of hot air causes the top floor temperature to be much higher than the bottom floor, forming a "steamer effect".

2. The contradiction between airtightness and heat dissipation: Although standard factories have good lighting, the window opening area is limited, and natural ventilation cannot meet the large-scale and high-intensity heat dissipation and dust removal needs.

3. Space utilization requirement: The production line layout should be compact, and no ventilation equipment should occupy valuable indoor floor working area.

Ruifeng Solution: Evaporative Air Cooler+Negative Pressure Fan Combination System

In response to the above difficulties, the Ruifeng Environmental Protection Refrigeration Technology Team has tailored a combined ventilation and cooling solution of "evaporative air cooler post air supply+negative pressure fan overall exhaust" based on three core factors: geographical climate characteristics, multi story factory structure, and production process requirements.

Equipment layout and working principle:

1. Evaporative air cooler (installed on walls/roofs): Taking advantage of the large temperature difference between dry and wet spheres in Yueyang during summer (which is also the season with the best evaporative cooling effect), we install the air cooler on the exterior walls or roofs of buildings. The equipment draws fresh outdoor air and uses the natural physical principle of "water evaporation absorbs heat" to lower the air temperature by 4-10 ℃. Then, it is precisely introduced into the indoor environment through the laid air supply ducts. This design occupies zero indoor floor area, completely solving the problem of tight space in multi story factories.

2. Negative pressure fan (installed on the opposite wall): Install a high flow negative pressure fan on the other side or top floor of the workshop to forcefully remove the hot air emitted from densely populated areas indoors, the waste heat generated by equipment operation, and the turbidity and odor generated by solidification and grinding processes from the outside.

Comprehensive application of physical principles and environmental improvement:

This design constructs a complete air convection system of "inlet+outlet", forming an indoor negative pressure state, forcing outdoor fresh air to flow evenly through the entire workshop like an invisible piston after being cooled by the air cooler, achieving dozens or even hundreds of air exchanges per hour.

1. Improved physical comfort: Continuous low-temperature fresh air takes away sweat from employees' bodies, achieving a refreshing feeling of "cooling without blowing people", significantly reducing the risk of heatstroke, and increasing the retention rate.

2. Product Quality Assurance: Quickly eliminates grinding dust and curing odors, ensuring the smoothness and bonding strength of high-end carbon fiber product coating surfaces, effectively reducing product defect rates.

3. Healthy air environment: Introducing oxygen enriched fresh air to dilute the concentration of air pollutants in the workshop, creating a truly healthy and green working environment for employees.

Project Value and Capability Extension

The successful implementation of the Yueyang Fishing Gear Factory project once again confirms the professional strength of Ruifeng Environmental Protection Refrigeration in engineering scheme design and ventilation cooling.

1. Similarity and scalability of business scenarios:

Although this is a case of a fishing equipment factory, the high temperature, odor, dust problems it faces, as well as the ventilation difficulties of multi story building structures, are highly similar to industry scenarios such as electronic assembly, food processing, clothing and textile, warehousing and logistics. Ruifeng can provide precise solutions for both clean painting workshops and intensive labor workshops that require heat dissipation.

2. Core competencies reflected:

This project fully demonstrates the Ruifeng team's profound understanding of multi-layer spatial airflow organization, as well as their refined construction capabilities in equipment comprehensive selection and scheme design. We not only provide equipment, but also offer three-dimensional ventilation design for complex building structures, including top floor heat dissipation, middle floor drainage, and bottom floor air supply.
