【案例背景与区域特性】

本项目位于制造业重镇——广东省佛山市。佛山地处珠江三角洲腹地，属于典型的亚热带季风性湿润气候，四季分明但长夏短冬。夏季漫长且高温高湿，年均气温约22-24°C，夏季最高温常突破35°C，且相对湿度常年维持在75%-85%之间。这种闷热的气候条件，对制造业车间的人员舒适度及生产环境稳定性提出了严峻挑战。同时，佛山作为全国知名的家电之都与金属材料加工基地，拥有雄厚的五金压铸与装备制造产业基础。

【客户概况】

本次服务的客户为佛山一家专业生产中高端炊具的知名企业。该企业专注于各类食品级不锈钢锅具、铝合金不粘锅以及耐高温塑料厨具的研发与制造，其产品线涵盖煎锅、汤锅、炒锅及厨房小配件等。作为与食品直接接触的产品制造商，企业对生产环境的洁净度、原材料的安全性以及生产工艺的稳定性有着极高的标准。

【生产工艺与车间环境挑战】

该企业的生产工艺链条完整且复杂，主要包含：原料冲压拉伸、压铸成型、抛光打磨、表面喷涂处理、高温烘烤固化以及组装包装等核心环节。材质上主要分为两大类：一是延展性与耐腐蚀性极佳的食品级304不锈钢；二是轻便且耐高温的食品级塑料及不粘涂层材料。

不同的生产工艺分布在不同的厂房结构中，带来了差异化的通风降温需求：

1、压铸车间： 位于单层彩钢框架结构厂房内（砖砌墙体，带隔热层的彩钢瓦屋顶）。该车间存在大量压铸机台，设备发热量大，金属熔融过程导致环境温度极高，且伴随少量油烟废气。

2、喷涂与组装车间： 位于三层混凝土框架结构的标准厂房内。喷涂车间需要保持微正压以防止灰尘进入，影响涂层表面光洁度；而组装包装车间人员密集，夏季闷热，对空气流通和人体舒适度要求较高。

【瑞峰方案：因地制宜，精准施策】

面对多厂房、多结构的复杂工况，瑞峰环保制冷的方案设计人员深入现场，结合佛山当地的高温高湿气候、各车间不同的设备发热量、产品特性（炊具半成品对湿度不敏感）以及车间宝贵的场地利用率等多方因素，进行了系统性研判。

最终方案摒弃了成本高昂且耗电巨大的传统压缩机空调，选用了“蒸发式冷风机（环保空调）+ 定制风管系统”的成熟组合方案。具体实施策略如下：

1、空间利用最大化： 针对车间内部寸土寸金、设备摆放密集的痛点，我们采用“空中取风，贴墙送风”的策略。所有蒸发式冷风机均通过钢结构支架安装于屋顶或外墙外侧，完全不占用车间内部的生产与物流通道空间。

2、物理原理应用： 蒸发式冷风机利用“水蒸发吸热”的自然物理原理，通过水泵将水均匀淋湿湿帘，当机外热空气穿过湿帘时，水分吸收空气中显热而蒸发，从而降低空气自身温度（通常降温幅度可达4-10℃），再由大风量风机通过连接好的镀锌螺旋风管将洁净、凉爽的冷风源源不断输送至车间深处。

3、差异化精准送风：

针对压铸车间的高温岗位，我们采用岗位送风方式，将冷风直接导向操作人员区域，极大改善了工人的作业环境，有效预防中暑风险，提升了生产安全性。

针对喷涂与组装车间，我们通过均匀布置的风管开孔，实现整体降温与换气。在引入凉爽新风的同时，强力排走车间内因设备和人流产生的热气、粉尘及异味，为喷涂工艺提供了更洁净的空气环境，间接提升了产品涂装的良品率。

【工程价值与成效】

项目实施后，车间环境得到了质的飞跃。过去那种“外面烈日烤，车间闷热熬”的局面彻底改变。工人们在清凉的环境中作业，工作积极性与留任率显著提升；同时，良好的通风也加快了产品（特别是喷涂件）表面的冷却速度，优化了生产流程节拍。

【业务延展与核心优势】

此次为炊具厂提供的通风降温服务，虽是瑞峰在五金压铸领域的又一成功案例，但其应用场景具有极强的可复制性与延展性。相似的场景包括但不限于：各类五金加工车间、塑料注塑车间、食品加工厂、制衣纺织厂以及大型仓储物流中心。这些场所普遍存在厂房空间高大、设备发热量大、人员密集、对湿度要求相对宽泛（非精密电子类） 等特点，正是蒸发式冷风机的用武之地。

瑞峰环保制冷通过此次项目，再次证明了我们在面对大空间、多建筑结构、复合型需求的复杂工程时，具备从设备综合选型（兼顾风量、风压、噪音与能效）到个性化方案设计，再到精细化施工落地的全链条专业能力。我们不仅是设备的安装者，更是企业车间环境的优化师。

Background and Regional Characteristics of the Case

This project is located in Foshan, a manufacturing hub in Guangdong Province. Foshan, located in the hinterland of the the Pearl River Delta, is a typical subtropical monsoon humid climate with four distinct seasons but long summer and short winter. Summer is long and characterized by high temperatures and humidity, with an average annual temperature of about 22-24 ° C. The highest temperature in summer often exceeds 35 ° C, and the relative humidity remains between 75% and 85% throughout the year. This hot and humid climate poses a severe challenge to the comfort of personnel and the stability of the production environment in manufacturing workshops. Meanwhile, Foshan, as a well-known home appliance capital and metal material processing base in China, has a strong foundation in hardware die-casting and equipment manufacturing industries.

[Customer Profile]

The client of this service is a well-known enterprise in Foshan that specializes in producing high-end cookware. This enterprise focuses on the research and manufacturing of various food grade stainless steel cookware, aluminum alloy non stick cookware, and high-temperature resistant plastic kitchenware. Its product line covers frying pans, soup pots, frying pans, and kitchen accessories. As a manufacturer of products that come into direct contact with food, enterprises have extremely high standards for the cleanliness of the production environment, the safety of raw materials, and the stability of production processes.

Production process and workshop environment challenges

The production process chain of this enterprise is complete and complex, mainly including core links such as raw material stamping and stretching, die-casting molding, polishing and grinding, surface spraying treatment, high-temperature baking and curing, and assembly and packaging. There are mainly two types of materials: one is food grade 304 stainless steel with excellent ductility and corrosion resistance; The second is lightweight and heat-resistant food grade plastics and non stick coating materials.

Different production processes are distributed in different factory structures, resulting in differentiated ventilation and cooling requirements:

1. Die casting workshop: located in a single-layer color steel frame structure factory building (brick walls, color steel tile roof with insulation layer). There are a large number of die-casting machines in this workshop, which generate a lot of heat. The process of metal melting leads to extremely high ambient temperatures and is accompanied by a small amount of oil fume exhaust gas.

2. Spray painting and assembly workshop: located in a standard factory building with a three story concrete frame structure. The spraying workshop needs to maintain a slight positive pressure to prevent dust from entering and affecting the surface smoothness of the coating; The assembly and packaging workshop is densely populated, with hot and humid summers, and high requirements for air circulation and human comfort.

Ruifeng Plan: Tailored to local conditions and precise implementation

Faced with complex working conditions with multiple factories and structures, the design personnel of Ruifeng Environmental Protection Refrigeration went deep into the site, combined with the high temperature and humidity climate in Foshan, the heat generation of different equipment in each workshop, product characteristics (semi-finished cooking utensils are insensitive to humidity), and the valuable site utilization rate of the workshop, and conducted a systematic analysis.

The final solution abandons the expensive and power consuming traditional compressor air conditioning and adopts a mature combination of "evaporative air cooler (environmentally friendly air conditioning)+customized air duct system". The specific implementation strategy is as follows:

1. Maximizing Space Utilization: In response to the pain points of limited space and dense equipment placement within the workshop, we adopt the strategy of "air intake from the air and wall mounted air supply". All evaporative air coolers are installed on the roof or exterior walls through steel structure brackets, without occupying any production or logistics channel space inside the workshop.

2. Application of physical principles: Evaporative air coolers use the natural physical principle of "water evaporation absorbs heat" to evenly wet the wet curtain through a water pump. When the hot air outside the machine passes through the wet curtain, the moisture absorbs the sensible heat in the air and evaporates, thereby reducing the temperature of the air itself (usually the cooling range can reach 4-10 ℃). Then, a large air volume fan continuously delivers clean and cool cold air to the deep workshop through a connected galvanized spiral air duct.

3. Differentiated precise air supply:

For the high-temperature positions in the die-casting workshop, we adopt a post air supply method to directly direct cold air to the operator area, greatly improving the working environment for workers, effectively preventing the risk of heatstroke, and enhancing production safety.

For the spraying and assembly workshop, we achieve overall cooling and ventilation through evenly arranged air duct openings. At the same time as introducing cool fresh air, it strongly exhausts the hot air, dust, and odors generated by equipment and personnel in the workshop, providing a cleaner air environment for the spraying process and indirectly improving the yield of product coating.

Engineering Value and Effectiveness

After the implementation of the project, the workshop environment has undergone a qualitative leap. The situation of "scorching sun outside and stuffy workshop" in the past has completely changed. Workers working in a cool environment have significantly improved their work enthusiasm and retention rate; At the same time, good ventilation also accelerates the cooling rate of the surface of products (especially spray painted parts), optimizing the production process rhythm.

Business Expansion and Core Advantages

The ventilation and cooling service provided to the cookware factory this time is another successful case of Ruifeng in the field of hardware die-casting, but its application scenarios have strong replicability and scalability. Similar scenarios include but are not limited to: various hardware processing workshops, plastic injection molding workshops, food processing plants, clothing and textile factories, and large warehousing and logistics centers. These places generally have the characteristics of large factory space, high equipment heat generation, dense personnel, and relatively broad humidity requirements (non precision electronics), which are exactly where evaporative air coolers come in.

Through this project, Ruifeng Environmental Protection Refrigeration once again proves our full chain professional capabilities in the face of complex projects with large spaces, multiple building structures, and composite requirements, from comprehensive equipment selection (taking into account air volume, air pressure, noise, and energy efficiency) to personalized scheme design, and then to fine construction implementation. We are not only installers of equipment, but also optimizers of enterprise workshop environments.
