一、项目背景

该厂位于广东省东莞市，属典型的亚热带季风气候，常年高温多湿，夏季漫长且闷热，秋冬季节湿度依然较高。此种气候环境对生产车间的温湿度控制提出了严峻挑战。客户是一家专业从事塑料五金制品生产的老牌企业，其厂房为早期建造的钢筋混凝土结构，层高仅约3.5米，车间内部隔断较多，单间最大面积不超过300平方米。此外，注塑机、熔融设备、压铸机等高发热生产设备密集运行，不仅持续散发大量热量，且塑料原料对环境温湿度较为敏感，易导致产品冷却不均、尺寸变形等问题，严重影响生产稳定性与产品良率。

二、挑战与需求分析

瑞峰工程技术团队经现场勘查，综合考量以下关键因素：

1、地理气候：东莞地区常年高温高湿，需强化降温与除湿双重功能；

2、厂房结构：老厂房密封性较好，但层高低、空间分隔复杂，适合采用内循环气流组织方案，避免冷量散失；

3、热负荷大：塑料熔融、五金加工设备持续产热，需匹配大功率制冷设备；

4、灵活分区：不同车间面积与布局差异大，需定制化分区送风方案。

三、解决方案

针对上述复杂条件，瑞峰设计团队摒弃“一刀切”模式，创新采用 “分区域匹配差异化机型” 的精准方案：

1、对于隔断多、单间面积小（≤100㎡）的车间群，采用立式管道型大功率省电工业空调，通过专业设计的风管系统将几间小车间连通，实现集中降温除湿，高效利用冷量，改善区域微循环；

2、对于相对开阔的大空间车间，则安装 立式双出风口轴流大功率工业空调，其出风柔和均匀、覆盖范围广，可有效避免直吹不适，同时满足大空间快速降温需求。

四、实施效果

系统投入运行后，车间工作环境得到显著改善：

1、温湿度持续稳定在工艺要求范围内，设备运行平稳，电能消耗同比降低；

2、产品冷却效率提升，塑料件变形率下降，生产良品率获得切实提高；

3、员工工作舒适度明显改善，进一步保障了生产安全与效率。

厂方对方案设计的前瞻性与安装专业性给予高度评价。

五、项目启示

本案例虽是塑料五金行业的车间改造，但其“复杂空间分区施策”的设计逻辑，同样适用于电子装配、纺织车间、仓储物流、食品加工等多类环境受限、热负荷不均的工业场景。瑞峰团队凭借 “一区一策” 的精细化设计与快速可靠的工程实施能力，再次印证我们在通风降温领域解决复杂现场问题的专业实力。

1、 Project Background

The factory is located in Dongguan City, Guangdong Province, which belongs to a typical subtropical monsoon climate with high temperatures and humidity throughout the year. The summer is long and humid, while the humidity remains high in autumn and winter. This climate environment poses a severe challenge to temperature and humidity control in production workshops. The client is an established enterprise specializing in the production of plastic and hardware products. Their factory building is an early constructed reinforced concrete structure with a floor height of only about 3.5 meters. There are many partitions inside the workshop, and the maximum area of a single room does not exceed 300 square meters. In addition, high heat production equipment such as injection molding machines, melting equipment, and die-casting machines operate intensively, not only continuously emitting a large amount of heat, but also plastic raw materials are sensitive to environmental temperature and humidity, which can easily lead to uneven cooling and dimensional deformation of products, seriously affecting production stability and product yield.

2、 Challenge and Requirements Analysis

After on-site investigation, the Ruifeng Engineering Technology Team has comprehensively considered the following key factors:

(1). Geographical climate: The Dongguan area experiences high temperatures and humidity throughout the year, and it is necessary to strengthen the dual functions of cooling and dehumidification;

(2). Factory structure: The old factory has good sealing, but the height of the floors and the spatial separation are complex, making it suitable to adopt an internal circulation airflow organization scheme to avoid loss of cooling capacity;

(3). High heat load: Plastic melting and metal processing equipment continue to generate heat, requiring high-power refrigeration equipment to be matched;

(4). Flexible zoning: Different workshops have significant differences in area and layout, requiring customized zoning air supply solutions.

3、 Solution

In response to the complex conditions mentioned above, the Ruifeng design team abandons the "one size fits all" model and innovatively adopts a precise solution of "matching differentiated models by region":

(1). For workshop groups with multiple partitions and small single room areas (≤ 100 ㎡), vertical pipeline type high-power energy-saving industrial air conditioning is used. Several small car rooms are connected through a professionally designed air duct system to achieve centralized cooling and dehumidification, efficient utilization of cooling capacity, and improvement of regional microcirculation;

(2). For relatively spacious workshops, vertical dual outlet axial flow high-power industrial air conditioners are installed. The air outlet is soft and uniform, with a wide coverage range, which can effectively avoid discomfort from direct blowing and meet the rapid cooling needs of large spaces.

4、 Implementation effect

After the system was put into operation, the working environment in the workshop was significantly improved:

(1). The temperature and humidity remain stable within the process requirements, the equipment runs smoothly, and the electricity consumption decreases year-on-year;

(2). The cooling efficiency of the product has been improved, the deformation rate of plastic parts has decreased, and the production yield has been effectively improved;

(3). The employee's work comfort has significantly improved, further ensuring production safety and efficiency.

The factory highly praised the forward-looking design and installation professionalism of the scheme.

5、 Project Inspiration

Although this case is a workshop renovation in the plastic hardware industry, its design logic of "complex spatial zoning" is also applicable to industrial scenarios with limited environments and uneven heat loads, such as electronic assembly, textile workshops, warehousing and logistics, and food processing. The Ruifeng team, with its refined design of "one zone, one strategy" and fast and reliable engineering implementation capabilities, once again confirms our professional strength in solving complex on-site problems in the field of ventilation and cooling.
