汕头市华美塑料模具实业有限公司，位于汕头市升平区。汕头地处广东东部沿海，属亚热带海洋性气候，夏季漫长且高温湿热，对生产车间的环境温度与通风换气提出了严峻挑战。作为一家集塑料制品、精密模具、文具及小家电生产于一体的综合性企业，其生产环境的好坏直接关系到产品质量与员工稳定性。

本次改造的核心区域为厂内一栋多层钢筋混凝土标准厂房。该建筑每层独立成车间，层高约5米，单层面积宽敞。优点在于采光良好、结构坚固，但也因密封性强、空气流通性差，导致了内部热量与气味积聚的问题。特别是模具制作车间的电火花、线切割等加工工序会产生油雾与热量，而模压成型车间的塑料原料在高温下会散发出不同程度的气味。加之设备密集、操作人员众多，使得车间内环境闷热、空气浑浊，极大影响了员工的体感舒适度和工作效率，一套高效、专业的通风降温方案势在必行。

瑞峰环保制冷的方案设计人员在深入现场勘测后，综合考虑了汕头当地湿热的气候特点、厂房的建筑结构、内部发热源分布、生产工艺需求以及人员密度等多重因素，最终摒弃了传统空调的高能耗与普通风扇的局部性弊端，为客户量身定制了“大风量离心式冷风机+长风管均匀送风”的组合方案。

此方案的核心优势在于“集中处理，定点输送，全面置换”。我们将大风量离心式冷风机巧妙地安装在厂房墙体外侧，这样做的好处是：其一，不占用宝贵的室内地面空间，保证了生产区域的完整与畅通；其二，设备从室外抽取新鲜空气，通过其核心的“湿帘蒸发”物理原理，利用水的蒸发吸热过程，对空气进行等焓降温，再将处理后的洁净冷空气加压送入室内。

冷空气通过架设于车间上方的长风管系统，被均匀地输送到厂房的每一个角落。我们在风管上科学地开设了多个风动百叶窗，确保冷气能以精准的角度和速度向下覆盖，形成一个个舒适的“冷气带”。源源不断送入的冷空气在车间内形成微正压，将原本聚集在空间内的热空气、异味、粉尘等有效“挤”出室外，实现了空气的完全置换。

工程完工后，车间环境得到了脱胎换骨的改善。夏季高温时段，车间内温度可有效降低，空气变得清新流通。员工们告别了以往的闷热难耐，工作状态更加专注投入；同时，良好的温湿度环境也保障了精密模具加工设备及注塑机控制系统的稳定运行，减少了因过热导致的故障率，间接提升了生产良率与效率。

汕头华美塑料模具厂的工程实践，是瑞峰公司在面对大面积、高热源、高人员密度生产车间时，又一次成功的技术验证。它充分证明了我们不仅拥有针对性的设备选型能力，更具备结合建筑特性与生产工艺，进行非标化、精细化方案设计与施工的系统解决能力。无论是类似的塑料制品厂、五金加工车间，还是电子装配、制衣纺织等需要大面积通风降温的场所，瑞峰都能为您提供专业、可靠、高性价比的环境改善服务。

Shantou Huamei Plastic Mold Industry Co., Ltd. is located in Shengping District, Shantou City. Shantou is located on the eastern coast of Guangdong Province, with a subtropical maritime climate. The summer is long and humid, posing severe challenges to the environmental temperature and ventilation of production workshops. As a comprehensive enterprise integrating the production of plastic products, precision molds, stationery, and small household appliances, the quality of its production environment directly affects product quality and employee stability.

The core area of this renovation is a multi story reinforced concrete standard factory building within the factory. The building has independent workshops on each floor, with a height of about 5 meters and a spacious single floor area. The advantages lie in good lighting and sturdy structure, but also in the problem of internal heat and odor accumulation due to strong sealing and poor air circulation. Especially in the mold making workshop, processes such as electrical discharge and wire cutting generate oil mist and heat, while plastic raw materials in the molding workshop emit varying degrees of odor at high temperatures. In addition, with dense equipment and numerous operators, the workshop environment is hot and humid, and the air is turbid, greatly affecting the comfort and work efficiency of employees. Therefore, an efficient and professional ventilation and cooling plan is imperative.

After conducting in-depth on-site investigations, the design team of Ruifeng Environmental Protection Refrigeration comprehensively considered multiple factors such as the humid and hot climate characteristics of Shantou, the building structure of the factory, the distribution of internal heat sources, production process requirements, and personnel density. Ultimately, they abandoned the high energy consumption of traditional air conditioners and the local drawbacks of ordinary fans, and tailored a combination solution of "high air volume centrifugal air coolers+long air ducts for uniform air supply" for customers.

The core advantage of this plan lies in "centralized processing, fixed-point transportation, and comprehensive replacement". We ingeniously installed high air volume centrifugal air coolers on the outside of the factory walls, which has the following advantages: firstly, it does not occupy valuable indoor floor space, ensuring the integrity and smoothness of the production area; Secondly, the equipment extracts fresh air from the outdoors and uses its core physical principle of "wet curtain evaporation" to absorb heat through water evaporation. It then uses the isentropic cooling of the air and pressurizes the treated clean cold air before sending it indoors.

Cold air is evenly delivered to every corner of the factory building through a long air duct system installed above the workshop. We have scientifically installed multiple aerodynamic louvers on the air ducts to ensure that the air conditioning can cover downwards at precise angles and speeds, forming comfortable 'air conditioning belts'. The continuous supply of cold air forms a slight positive pressure in the workshop, effectively "squeezing" the hot air, odors, dust, and other substances that originally gathered in the space out of the room, achieving complete replacement of air.

After the completion of the project, the workshop environment underwent a complete transformation and improvement. During the high temperature period in summer, the temperature in the workshop can be effectively reduced, and the air becomes fresh and well circulated. The employees bid farewell to the stuffy and unbearable heat of the past, and became more focused and engaged in their work; At the same time, a good temperature and humidity environment also ensures the stable operation of precision mold processing equipment and injection molding machine control systems, reducing the failure rate caused by overheating and indirectly improving production yield and efficiency.

The engineering practice of Shantou Huamei Plastic Mold Factory is another successful technical verification for Ruifeng Company when facing large-scale, high heat source, and high personnel density production workshops. It fully proves that we not only have the ability to select targeted equipment, but also have the system solution ability to combine building characteristics and production processes for non-standard and refined scheme design and construction. Whether it's similar plastic product factories, hardware processing workshops, or places that require large-scale ventilation and cooling such as electronic assembly, clothing, and textiles, Ruifeng can provide you with professional, reliable, and cost-effective environmental improvement services.
