【项目背景与挑战】

港泉精密制品（深圳）有限公司，坐落于深圳市宝安区。深圳地处南海之滨，属于亚热带海洋性气候，夏季漫长且高温湿热，对工业生产环境，尤其是对散热需求巨大的注塑车间而言，是一项严峻挑战。作为改革开放的前沿阵地与全球知名的制造业基地，深圳的精密制造产业对生产环境的稳定性、产品质量的可靠性有着极高的要求。

港泉公司是一家专注于生产各类高精度注塑产品的现代化企业。在注塑生产过程中，注塑机会释放出大量的热量，同时伴随着塑料熔融时产生的少量挥发性气体。若车间通风不畅，热量和浊气积聚，不仅会导致车间温度飙升，影响一线员工的作业舒适度与工作效率，更可能因环境温度波动或空气污浊，对精密注塑件的定型精度与表面光洁度造成潜在影响，从而威胁产品良率。

该公司的生产车间为多层钢筋混凝土结构的标准厂房，虽然结构稳固、采光良好，但层高、密闭性等特点也使得内部热量和空气难以自然对流，形成高温、闷热的作业环境。因此，一套高效、科学的通风降温解决方案，成为提升员工福祉与保障生产品质的必然之选。

【瑞峰方案：精准设计与专业实施】

面对港泉公司的具体需求与现场工况，瑞峰环保制冷的方案设计团队深入现场，综合考量了深圳当地高温高湿的气候特征、厂房多层建筑的承重与结构、注塑生产工艺对温度与空气洁净度的特殊要求，以及空间利用率等多方因素，最终为其量身定制了“大功率不锈钢蒸发式冷风机 + 长风管均匀送风”的组合方案。

核心设备： 选用大功率不锈钢蒸发式冷风机。其原理是利用“水蒸发吸热”这一自然物理现象，通过高效湿帘将室外新鲜空气降温，并转化为清新、湿润的冷气。设备整体采用不锈钢材质，坚固耐用，能从容应对注塑车间可能存在的复杂工业环境，使用寿命更长。

1、安装方式： 主机设备全部安装于建筑墙体外侧，风管通过墙体开孔引入室内。此举最大化节省了车间内部宝贵的生产与仓储面积，实现了“设备在墙外，清凉在墙内”的效果。

2、气流组织： 通过精心设计的长风管系统，将处理后的冷气精准、均匀地输送到车间各个工位。大功率风机产生的强大气流，使室内形成稳定的微正压环境，持续将人员活动、机器设备产生的热气、粉尘及异味有效挤出室外，实现了“送冷、排热、换气”三位一体的高效循环。

【实施效果与客户价值】

方案实施后，港泉注塑车间的闷热状况得到根本性改善：

1、环境显著改善： 车间整体温度得到有效控制，空气流通顺畅，浊气排出及时，空气质量大幅提升。

2、体感舒适度提升： 一线员工告别了以往的“蒸笼”式作业环境，体感舒适度显著增强，有效降低了因高温引发的疲劳与烦躁，间接提升了生产效率与稳定性。

3、产品质量保障： 稳定、清爽的车间环境，为注塑件的冷却定型创造了更佳的条件，对保障产品尺寸精度和外观品质起到了积极作用。

4、节能环保运营： 蒸发式冷风机相较于传统空调，具有投资成本低、运行能耗低的显著优势，符合当下绿色工厂的倡导方向。

【专业能力延伸】

此次港泉注塑车间工程的圆满成功，再次验证了瑞峰环保制冷在大空间通风降温领域的专业实力。虽然服务的是注塑车间，但其背后所解决的高温、异味、空气流通不畅等问题，是五金加工、电子装配、服装制造、仓储物流等诸多行业大型生产车间的共性痛点。

这充分说明，瑞峰公司不仅具备针对单一行业的服务能力，更拥有跨行业的、针对大跨度、高热量、高人员密度空间的综合性方案设计与设备选型能力。我们不仅能提供标准化的设备，更能根据不同企业的建筑结构、生产工艺和预算，提供“量体裁衣”式的专业定制服务。

Project Background and Challenges

Gangquan Precision Products (Shenzhen) Co., Ltd. is located in Bao'an District, Shenzhen. Shenzhen is located on the coast of the South China Sea, with a subtropical maritime climate. The summer is long and hot, humid, and humid, which poses a severe challenge for industrial production environments, especially for injection molding workshops with huge heat dissipation requirements. As a forefront of reform and opening up and a globally renowned manufacturing base, Shenzhen's precision manufacturing industry has extremely high requirements for the stability of the production environment and the reliability of product quality.

Gangquan Company is a modern enterprise dedicated to producing various high-precision injection molded products. During the injection molding production process, the injection molding machine releases a large amount of heat, accompanied by a small amount of volatile gases generated when the plastic melts. If the ventilation in the workshop is poor and heat and turbidity accumulate, it will not only cause the workshop temperature to soar, affecting the comfort and efficiency of frontline employees, but also potentially affect the shaping accuracy and surface smoothness of precision injection molded parts due to environmental temperature fluctuations or air pollution, thereby threatening product yield.

The production workshop of the company is a standard multi story reinforced concrete structure factory building. Although the structure is stable and the lighting is good, the characteristics of the floor height and airtightness also make it difficult for internal heat and air to naturally circulate, creating a high-temperature and humid working environment. Therefore, an efficient and scientific ventilation and cooling solution has become an inevitable choice to improve employee well-being and ensure production quality.

Ruifeng Plan: Precise Design and Professional Implementation

Faced with the specific needs and on-site conditions of Gangquan Company, the design team of Ruifeng Environmental Protection Refrigeration went deep into the site and comprehensively considered the local high temperature and high humidity climate characteristics in Shenzhen, the load-bearing and structural characteristics of multi story buildings in the factory, the special requirements of injection molding production technology for temperature and air cleanliness, as well as space utilization and other factors. Finally, they tailored a combination scheme of "high-power stainless steel evaporative air cooler+long air duct uniform air supply" for it.

Core equipment: High power stainless steel evaporative air cooler is selected. The principle is to use the natural physical phenomenon of "water evaporation absorbs heat" to cool the fresh outdoor air through efficient wet curtains and convert it into fresh and humid air. The overall equipment is made of stainless steel material, which is sturdy and durable, and can easily cope with the complex industrial environment that may exist in the injection molding workshop, with a longer service life.

1. Installation method: All host devices are installed on the outside of the building wall, and air ducts are introduced into the room through wall openings. This maximizes the saving of valuable production and storage area within the workshop, achieving the effect of "equipment outside the wall, coolness inside the wall".

2. Airflow organization: Through a carefully designed long air duct system, the processed cold air is accurately and evenly delivered to various workstations in the workshop. The powerful airflow generated by high-power fans creates a stable micro positive pressure environment indoors, continuously squeezing out the hot air, dust, and odors generated by personnel activities, machinery and equipment, achieving an efficient cycle of "cooling, heat dissipation, and ventilation".

Implementation Effect and Customer Value

After the implementation of the plan, the stuffiness in the Gangquan injection molding workshop has been fundamentally improved:

1. Significant improvement in environment: The overall temperature of the workshop has been effectively controlled, air circulation is smooth, turbid air is discharged in a timely manner, and air quality has been greatly improved.

2. Improved physical comfort: Frontline employees have bid farewell to the traditional "steamer" work environment, significantly enhancing their physical comfort, effectively reducing fatigue and irritability caused by high temperatures, and indirectly improving production efficiency and stability.

3. Product quality assurance: A stable and refreshing workshop environment creates better conditions for the cooling and shaping of injection molded parts, which plays a positive role in ensuring product dimensional accuracy and appearance quality.

4. Energy saving and environmentally friendly operation: Compared with traditional air conditioners, evaporative air coolers have significant advantages in low investment costs and low operating energy consumption, which is in line with the current advocacy direction of green factories.

Extension of Professional Skills

The successful completion of the Gangquan injection molding workshop project once again confirms the professional strength of Ruifeng Environmental Protection Refrigeration in the field of large space ventilation and cooling. Although serving the injection molding workshop, the problems of high temperature, odor, and poor air circulation behind it are common pain points for many large-scale production workshops in industries such as hardware processing, electronic assembly, clothing manufacturing, and warehousing and logistics.

This fully demonstrates that Ruifeng Company not only has the ability to provide services for a single industry, but also has the ability to design comprehensive solutions and select equipment for large-span, high heat, and high-density spaces across industries. We can not only provide standardized equipment, but also offer tailored professional customization services based on the building structure, production process, and budget of different enterprises.
