【项目背景与客户概况】

威尼科技发展有限公司（下称“威尼科技”）位于广州市白云区。广州地处亚热带季风气候区，夏季高温、湿度大且持续时间长，对生产车间的通风降温提出了较高要求。作为华南地区重要的制造业基地，广州汇聚了大量高标准的医疗器械与防护用品生产企业，产业集聚效应显著，对生产环境的要求亦日益严苛。

威尼科技自2003年起专注于防护口罩的研发与生产，拥有美国EUA、欧盟CE、澳洲AS1716、俄罗斯EAC等多项国际认证，并参与了国家标准GB2626的制定及公安部警用防雾霾口罩的研发与制造。公司还创新研发了中药抗病毒功能口罩，是国内首批将中药产业与口罩制造相结合的企业之一。在疫情期间，威尼科技更是首批将中国KN95口罩出口欧盟意大利的企业，展现了强大的研发实力与国际影响力。

目前，公司拥有厂房面积达6万平方米，员工近千人，是国内口罩行业前十强企业。在湖北疫情期间，威尼科技积极履行社会责任，向武汉、孝感、云梦、安陆等地区医院捐赠大量口罩，被中国劳保协会授予“抗疫英雄”称号。

【项目需求与设计思路】

威尼科技的生产车间面积大、人员密集、设备发热量大，传统的中央空调不仅初投资高、运行成本大，且难以实现局部精准送风；而普通风扇又无法有效降温换气，难以满足生产环境的要求。

瑞峰环保制冷的方案设计人员在充分调研现场情况后，综合考虑以下因素：

1、地理环境因素：广州高温高湿的气候特点要求设备具备强降温效果与良好的通风换气能力；

2、车间结构特点：车间空间大、层高高，适合采用正压送风方式进行整体换气；

3、设备布局限制：车间内部设备密集，需避免占用生产区域，保证生产动线顺畅；

4、节能与环保要求：客户希望降低运行成本，同时保障员工舒适度，提升生产效率。

【瑞峰方案实施与效果】

基于以上分析，瑞峰团队为客户推荐了蒸发式冷风机（环保空调）作为核心降温设备。该设备利用水蒸发吸热的物理原理，通过高效湿帘与风机系统，将室外新鲜空气降温后持续送入室内，形成正压环境，将车间内积聚的热空气、粉尘及异味迅速排出室外，实现“降温+换气+增氧”三效合一。

为最大化节省车间空间，所有冷风机均安装在墙外侧，通过定制风管系统将冷风精准引入各工位区域，既保证了送风效果，又不影响车间内部设备布局与生产动线。改造后，车间内温度明显下降，空气流通性大幅提升，员工工作环境显著改善，生产效率与产品合格率也得到同步提升。

【案例延伸与价值体现】

此次虽是口罩生产车间的降温工程，但其应用场景与解决方案具有广泛借鉴意义。类似如电子组装车间、食品加工厂、仓储物流中心等大空间、高密度作业场所，均可通过蒸发式冷风机系统实现低成本、高效能的通风降温改造。

瑞峰环保制冷在此项目中，充分展现了面对大空间复杂环境下的设备综合选型能力与精细化方案设计施工能力。无论是从气候适应性分析、设备布局优化，还是从施工配合与后期运行效果来看，瑞峰都以专业水准赢得了客户的高度认可。

Project Background and Customer Profile

Weini Technology Development Co., Ltd. (hereinafter referred to as "Weini Technology") is located in Baiyun District, Guangzhou City. Guangzhou is located in the subtropical monsoon climate zone, with high temperatures, high humidity, and long duration in summer, which places high demands on ventilation and cooling in production workshops. As an important manufacturing base in southern China, Guangzhou has gathered a large number of high standard medical equipment and protective equipment production enterprises, with significant industrial agglomeration effects and increasingly stringent requirements for the production environment.

Since 2003, Weini Technology has been focusing on the research and production of protective masks, with multiple international certifications such as EUA in the United States, CE in the European Union, AS1716 in Australia, and EAC in Russia. It has also participated in the development of the national standard GB2626 and the research and manufacturing of anti haze masks for police use by the Ministry of Public Security. The company has also innovatively developed traditional Chinese medicine antiviral functional masks, which is one of the first enterprises in China to combine the traditional Chinese medicine industry with mask manufacturing. During the epidemic, Weini Technology was one of the first companies to export Chinese KN95 masks to the European Union and Italy, demonstrating strong research and development capabilities and international influence.

At present, the company has a factory area of 60000 square meters and nearly a thousand employees, making it one of the top ten companies in the domestic mask industry. During the epidemic in Hubei, Weini Technology actively fulfilled its social responsibility by donating a large number of masks to hospitals in Wuhan, Xiaogan, Yunmeng, Anlu and other areas, and was awarded the title of "Anti epidemic Hero" by the China Labor Insurance Association.

Project Requirements and Design Ideas

The production workshop of Weini Technology has a large area, dense personnel, and high equipment heat generation. Traditional central air conditioning not only has high initial investment and operating costs, but also struggles to achieve precise local air supply; However, ordinary fans are unable to effectively cool and ventilate, making it difficult to meet the requirements of the production environment.

After conducting a thorough investigation of the on-site situation, the design personnel of Ruifeng Environmental Protection Refrigeration have comprehensively considered the following factors:

1. Geographical environmental factors: The high temperature and humidity climate characteristics of Guangzhou require equipment to have strong cooling effects and good ventilation and air exchange capabilities;

2. Workshop structural characteristics: The workshop has a large space and high floor height, suitable for using positive pressure air supply for overall ventilation;

3. Equipment layout restrictions: The workshop is densely packed with equipment, so it is necessary to avoid occupying the production area and ensure smooth production flow;

4. Energy saving and environmental protection requirements: Customers hope to reduce operating costs while ensuring employee comfort and improving production efficiency.

Implementation and Effect of Ruifeng Plan

Based on the above analysis, the Ruifeng team recommends evaporative air coolers (environmentally friendly air conditioners) as the core cooling equipment for customers. This device utilizes the physical principle of water evaporation to absorb heat. Through an efficient wet curtain and fan system, it continuously sends fresh outdoor air into the room after cooling, creating a positive pressure environment. It quickly exhausts the accumulated hot air, dust, and odors in the workshop, achieving the three effects of "cooling+ventilation+oxygenation".

To maximize the saving of workshop space, all air coolers are installed on the outside of the wall, and the cold air is precisely introduced into each workstation area through a customized air duct system, ensuring the air supply effect without affecting the layout of internal equipment and production lines in the workshop. After the renovation, the temperature in the workshop significantly decreased, the air circulation was greatly improved, the working environment for employees was significantly improved, and the production efficiency and product qualification rate were also synchronously improved.

Case Extension and Value Reflection

Although this is a cooling project for the mask production workshop, its application scenarios and solutions have broad reference significance. Large spaces and high-density workplaces such as electronic assembly workshops, food processing plants, and warehousing and logistics centers can be transformed into low-cost and high-efficiency ventilation and cooling systems through evaporative cooling systems.

In this project, Ruifeng Environmental Protection Refrigeration fully demonstrates its ability to comprehensively select equipment and design and construct refined solutions in complex environments with large spaces. Whether in terms of climate adaptability analysis, equipment layout optimization, or construction coordination and post operation effects, Ruifeng has won high recognition from customers with professional standards.
