【项目背景与挑战】

本项目位于浙江省丽水市。丽水地处浙西南山区，属于亚热带季风气候，夏季炎热潮湿，冬季阴冷。虽然林木资源丰富，为造纸产业提供了基础原料，但复杂的地理环境也导致车间空气流通性差，闷热感强。

该客户是一家专注于生产生活用纸（纸巾）的专业厂家。纸巾作为现代生活的快消品，其需求量巨大，且消费者对纸张的柔软度、洁净度要求极高。纸巾的生产工艺（如复卷、切割、包装）对环境的湿度和温度尤为敏感：湿度过高会导致纸张受潮变形、产生褶皱，影响成品率；温度过高则影响设备运行稳定及员工操作舒适度。因此，如何在夏季高温高湿的气候下，既保证产品质量，又改善员工作业环境，成为摆在企业面前的难题。

【瑞峰方案：组合式创新布局】

针对该厂的实际痛点，瑞峰环保制冷的方案设计团队进行了多维度因素的综合考量：

1、地理气候因素： 丽水山区湿度大，单纯通风效果有限，必须结合主动除湿手段。

2、产品特性因素： 纸巾属于轻质产品，气流过大会吹飞纸张或导致包装错位，因此送风必须柔和，不能采用传统的强对流吹风。

3、工艺需求因素： 生产区域需要维持相对恒定的温湿度，以确保设备精度和纸张物理性能稳定。

基于以上分析，瑞峰团队创新性地提出了“一台长风管蒸发式冷风机与一台工业空调错位间隔布局”的组合方案。这种布局方式巧妙融合了通风与制冷的双重优势：

1、冷风机（核心作用：通风换气+降温）： 利用水蒸发吸热的物理原理，将室外富含氧气的新鲜空气过滤降温后，通过长风管均匀输送至车间内部。这不仅形成了微正压环境，有效将人员密集区产生的浊气和热气挤出室外，保证了空气的清新度，同时柔和的气流避免了直接吹乱轻质纸巾的困扰。

2、工业空调（核心作用：精确控温除湿）： 针对梅雨季或极端高温天气，工业空调启动主动制冷模式。根据热力学原理，空调在制冷的同时能有效去除空气中的水蒸气（冷凝除湿），将车间温湿度牢牢控制在生产工艺要求的范围内。

【实施效果与环境改善】

设备安装运行后，车间环境得到了质的飞跃：

1、人体舒适度提升： 员工告别了以往闷热流汗的工作状态，体感温度显著下降，工作积极性和留岗率明显提高。

2、产品品质保障： 由于湿度得到了精确控制，纸张返潮、变形的问题得到遏制，产品合格率上升，包装工序也更加顺畅。

3、能耗与环保平衡： 错位布局使得冷风机负责大空间的基础换气降温，空调仅作为温湿度精准调控的补充，既避免了过度依赖空调导致的高昂电费，又符合环保节能的现代工业理念。

【拓展应用与瑞峰实力】

此次针对丽水纸巾厂的成功改造，虽然是特定行业的案例，但其技术逻辑具备广泛的延展性。类似场景如：电子车间（需防静电控湿）、食品包装车间（需洁净控温）、纺织车间（需增湿防静电兼顾降温） 等对环境有特殊要求的生产空间，均可参考此类组合方案。

瑞峰环保制冷通过此项目，充分证明了我们不仅具备通风降温工程的基础施工能力，更拥有针对特殊生产环境、敏感工艺流程进行综合设备选型与定制化方案设计的专业实力。无论您的厂房面临何种复杂的环境挑战，瑞峰都能为您提供科学、高效、节能的系统性解决方案。

Project Background and Challenges

This project is located in Lishui City, Zhejiang Province. Lishui is located in the southwestern mountainous area of Zhejiang Province, with a subtropical monsoon climate. It is hot and humid in summer and cold in winter. Although forest resources are abundant and provide basic raw materials for the paper industry, the complex geographical environment also leads to poor air circulation and strong stuffiness in the workshop.

This client is a professional manufacturer specializing in the production of household paper (tissue). As a fast-moving consumer product in modern life, tissue paper has a huge demand, and consumers have extremely high requirements for the softness and cleanliness of paper. The production process of paper towels (such as rewinding, cutting, packaging) is particularly sensitive to the humidity and temperature of the environment: too high humidity will cause the paper to be affected by moisture, deformation, wrinkles, and affect the yield; If the temperature is too high, it will affect the stability of equipment operation and the comfort of employees. Therefore, how to ensure product quality and improve the working environment for employees in the hot and humid climate of summer has become a challenge for enterprises.

Ruifeng Plan: Combination Innovation Layout

In response to the actual pain points of the factory, the design team of Ruifeng Environmental Protection Refrigeration has conducted a comprehensive consideration of multiple factors:

1. Geographical and climatic factors: The humidity in the Lishui mountainous area is high, and the effectiveness of simple ventilation is limited. Therefore, active dehumidification methods must be combined.

2. Product characteristic factors: Paper towels are lightweight products, and excessive airflow can blow away paper or cause packaging misalignment. Therefore, the air supply must be gentle and traditional strong convection blowing cannot be used.

3. Process requirement factor: The production area needs to maintain a relatively constant temperature and humidity to ensure equipment accuracy and stable physical properties of the paper.

Based on the above analysis, the Ruifeng team innovatively proposed a combination scheme of "a long duct evaporative air cooler and an industrial air conditioner with staggered spacing layout". This layout cleverly combines the dual advantages of ventilation and cooling:

1. Air cooler (core function: ventilation+cooling): Using the physical principle of water evaporation and heat absorption, it filters and cools the fresh air rich in oxygen outside, and evenly delivers it to the workshop through long air ducts. This not only creates a slightly positive pressure environment, effectively squeezing out the turbid and hot air generated in densely populated areas, ensuring the freshness of the air, but also avoiding the trouble of directly blowing lightweight tissues with gentle airflow.

2. Industrial air conditioning (core function: precise temperature control and dehumidification): For rainy season or extreme high temperature weather, industrial air conditioning starts active cooling mode. According to thermodynamic principles, air conditioning can effectively remove water vapor from the air (condensation dehumidification) while cooling, firmly controlling the temperature and humidity of the workshop within the range required by the production process.

Implementation effect and environmental improvement

After the installation and operation of the equipment, the workshop environment has undergone a qualitative leap:

1. Improved human comfort: Employees have bid farewell to the previous hot and humid work state, with a significant decrease in perceived temperature and a significant increase in work enthusiasm and retention rate.

2. Product quality assurance: Due to precise humidity control, the problems of paper moisture regain and deformation are curbed, the product qualification rate increases, and the packaging process becomes smoother.

3. Balancing energy consumption and environmental protection: The staggered layout allows the air cooler to be responsible for the basic ventilation and cooling of large spaces, while the air conditioner only serves as a supplement to precise temperature and humidity control. This not only avoids the high electricity costs caused by excessive reliance on air conditioning, but also conforms to the modern industrial concept of environmental protection and energy conservation.

Expanding Applications and Enhancing Ruifeng's Strength

The successful transformation of Lishui tissue factory this time, although a specific industry case, has broad scalability in its technical logic. Similar scenarios, such as electronic workshops (requiring anti-static and humidity control), food packaging workshops (requiring clean and temperature controlled), textile workshops (requiring humidification, anti-static, and cooling), and other production spaces with special environmental requirements, can all refer to such combination schemes.

Through this project, Ruifeng Environmental Protection Refrigeration fully proves that we not only have the basic construction capability of ventilation and cooling engineering, but also have the professional strength to select comprehensive equipment and design customized solutions for special production environments and sensitive process flows. No matter what complex environmental challenges your factory faces, Ruifeng can provide you with scientific, efficient, and energy-saving systematic solutions.
