一、项目背景与厂区概况

该制衣厂位于柬埔寨金边市郊大型产业园区内，地处热带季风气候区，全年高温高湿，旱季平均气温达30-35℃，雨季湿度常超过80%，湿热环境对生产车间的人员作业与设备运行构成显著挑战。作为柬埔寨支柱产业之一，制衣业长期承接中国纺织服装产业链的转移，形成了以劳动密集型为主的产业模式，也成为中柬产能合作的重要领域。

厂区为典型彩钢结构厂房，屋顶采用彩钢瓦，四周砌筑砖墙，整体密封性一般。车间总面积约20000平方米，层高12米，内部依生产工艺划分为裁剪区、缝纫区、熨烫区、质检区及包装区等，涵盖裁剪工、缝纫工、熨烫工、品检员等多类工种，人员密集且流动性高。

二、核心挑战：熨烫区高温高湿环境

熨烫工序需持续使用高温蒸汽设备，导致该区域温湿度显著高于车间其他部位。由于厂房内部无物理隔断，热湿空气易扩散至相邻工段，既影响员工舒适度，也制约整体生产效率。如何在开放式大空间内实现局部精准降温除湿，成为本项目需解决的关键课题。

三、瑞峰定制化解决方案

基于对地理气候、厂房结构、能源条件及生产动线的综合调研，瑞峰技术团队聚焦以下维度进行方案设计：

1、建筑热工分析：彩钢屋顶与砖墙结构的隔热性能较弱，且厂房密封性不足，冷量损失显著；

2、空间气流组织：开放式车间需合理规划送风路径，避免冷热气流混杂；

3、本地化适配：柬埔寨电网电压为230V/50Hz，与中国标准不同，且当地电力供应不稳定，须优先选择高能效、低功耗设备；

4、成本与维护：考虑当地技术资源有限，方案需兼顾设备可靠性与运维简便性。

最终方案：采用定制化卧式风管蒸发冷却工业空调系统，依据熨烫区岗位分布进行定点送风设计。设备电机与控制系统均适配柬埔寨电压标准，并通过变频技术与高效蒸发滤网实现节能运行，大幅降低能耗负荷。

四、工程成效与客户反馈

系统投用后，熨烫区温度下降8-12℃，相对湿度降低约30%，工作人员体感舒适度明显提升。凉爽干燥的工作环境不仅减少了员工疲劳感，更使熨烫工序效率提高约15%，产品返工率同步下降。厂方管理层对瑞峰团队“精准送风、高效节能”的设计理念表示高度认可，该项目也成为园区内可持续厂务升级的示范案例。

五、行业展望：中国方案助力东南亚工业升级

当前东南亚多国正处在工业化加速阶段，其厂房条件、气候特征与能源结构与中国数十年前的发展路径相似。许多劳动密集型产业面临高温高湿、电力紧张、基础设施不足的共同挑战。然而，当地往往缺乏专业的环境控制技术与供应链支持。

瑞峰环保制冷依托中国成熟的制造体系与工程经验，将高效、可定制、易维护的通风降温解决方案输出至柬埔寨及周边市场，助力当地产业实现生产环境与能效管理的双重提升。未来，我们愿继续以“中国技术”与“中国方案”，为“一带一路”沿线国家的工业现代化注入绿色动能。

1、 Project Background and Factory Overview

The garment factory is located in a large industrial park on the outskirts of Phnom Penh, Cambodia, in a tropical monsoon climate zone with high temperatures and humidity throughout the year. The average temperature during the dry season reaches 30-35 ℃, and the humidity during the rainy season often exceeds 80%. The humid and hot environment poses significant challenges to the operation of personnel and equipment in the production workshop. As one of the pillar industries in Cambodia, the garment industry has long undertaken the transfer of China's textile and clothing industry chain, forming a labor-intensive industry model and becoming an important area of production capacity cooperation between China and Cambodia.

The factory area is a typical color steel structure factory building, with a roof made of color steel tiles and surrounded by brick walls. The overall sealing is average. The total area of the workshop is about 20000 square meters, with a floor height of 12 meters. The interior is divided into cutting area, sewing area, ironing area, quality inspection area, and packaging area according to the production process, covering various types of workers such as cutting workers, sewing workers, ironing workers, and quality inspectors. The personnel is dense and the mobility is high.

2、 Core challenge: High temperature and high humidity environment in the ironing area

The ironing process requires continuous use of high-temperature steam equipment, resulting in significantly higher temperature and humidity in this area compared to other parts of the workshop. Due to the lack of physical partitions inside the factory building, hot and humid air is prone to spread to adjacent sections, which not only affects employee comfort but also restricts overall production efficiency. How to achieve precise local cooling and dehumidification in open large spaces has become a key issue that needs to be addressed in this project.

3、 Ruifeng customized solution

Based on comprehensive research on geographical climate, factory structure, energy conditions, and production lines, the Ruifeng technical team focuses on the following dimensions for scheme design:

(1) Thermal analysis of buildings: The thermal insulation performance of color steel roofs and brick wall structures is weak, and the sealing of the factory building is insufficient, resulting in significant cooling loss;

(2) Space airflow organization: Open workshops need to plan the air supply path reasonably to avoid mixing of hot and cold airflows;

(3) Localized adaptation: The voltage of the Cambodian power grid is 230V/50Hz, which is different from the Chinese standard, and the local power supply is unstable. High energy efficiency and low-power equipment should be prioritized;

(4) Cost and maintenance: Considering the limited local technical resources, the plan needs to balance equipment reliability and ease of operation and maintenance.

Final solution: Adopt a customized horizontal duct evaporative cooling industrial air conditioning system, and design fixed-point air supply according to the distribution of ironing area positions. The equipment motor and control system are both compatible with Cambodian voltage standards, and energy-saving operation is achieved through frequency conversion technology and efficient evaporation filters, significantly reducing energy consumption load.

4、 Engineering effectiveness and customer feedback

After the system was put into use, the temperature in the ironing area decreased by 8-12 ℃, the relative humidity decreased by about 30%, and the comfort level of the staff was significantly improved. The cool and dry working environment not only reduces employee fatigue, but also improves the efficiency of the ironing process by about 15%, and the product rework rate decreases synchronously. The management of the factory highly recognizes the design concept of "precise air supply, high efficiency and energy saving" of the Ruifeng team, and this project has become a demonstration case of sustainable factory upgrading in the park.

5、 Industry Outlook: China's Solution Helps Southeast Asia's Industrial Upgrading

Currently, many Southeast Asian countries are in the stage of accelerated industrialization, and their factory conditions, climate characteristics, and energy structure are similar to China's development path decades ago. Many labor-intensive industries face common challenges such as high temperatures and humidity, power shortages, and inadequate infrastructure. However, the local area often lacks professional environmental control technology and supply chain support.

Ruifeng Environmental Protection Refrigeration relies on China's mature manufacturing system and engineering experience to export efficient, customizable, and easy to maintain ventilation and cooling solutions to Cambodia and surrounding markets, helping local industries achieve dual improvement in production environment and energy efficiency management. In the future, we are willing to continue to inject green momentum into the industrial modernization of countries along the "the Belt and Road" with "China's technology" and "China's plan".
