一、项目背景

该鞋业生产基地位于浙江省瑞安市仙降镇，地处东南沿海，属亚热带季风气候区，四季分明，夏季炎热潮湿，冬季温和湿润。常年平均气温约17-18℃，夏季最高气温可达35℃以上，平均相对湿度较高，尤其在梅雨季节及夏季，车间内易出现闷热、空气流通不畅等问题，对生产环境与人员作业舒适度构成较大挑战。

二、厂房结构与车间概况

厂区建筑为多层钢筋混凝土标准厂房，需进行通风降温改造的车间面积约2200平方米，层高5.5米。车间主要划分为缝纫主区域与辅助功能区（包括整理区、临时存储周转区）。缝纫区密集布置工业缝纫设备，其本身虽无明显发热，但车间内长期驻留作业人员约280人，属于典型劳动密集型生产场景，人员散热成为车间内部主要热负荷来源。

三、原有环境与改造动因

此前，车间仅依靠传统风扇进行通风，空气流通效果有限，无法有效降低体感温度与控制湿度。高温高湿环境导致员工工作舒适度差，疲劳感加剧，长期以往造成员工流失率偏高。为提升员工稳定性、改善作业条件，同时确保鞋类生产过程中面料与成品对温湿度的敏感要求，业主决定对车间环境进行系统性升级。

四、方案设计与技术选型

瑞峰技术团队综合考虑多项关键因素，包括：

1、地理气候特点：针对本地夏季高温高湿的气候特征，需强化降温与除湿能力；

2、厂房结构条件：利用较高层高，采用空中安装方式，避免占用宝贵的地面生产空间；

3、车间布局与热源特性：结合人员密集、设备排列紧凑的特点，需实现远距离、大范围均匀送风；

4、系统效率与节能要求：在保证制冷效果的同时，控制运行成本，提升整体能效。

基于以上分析，最终选定大功率卧式射流蒸发冷工业空调系统。该设备采用吊挂式安装，不仅节约地面使用面积，更能通过强效射流送风技术，实现空气远距离输送与车间全域覆盖，有效促进空气循环与温度均衡。

五、实施效果与效益提升

系统投用后，车间整体温湿度得到精准控制，夏季室内温度保持在26-28℃的舒适范围，相对湿度显著下降。员工在清凉干爽的环境中作业，体感舒适度大幅提升，工作积极性与专注度明显增强，人员流失现象得到有效缓解。

生产环境改善进一步带动了企业综合效益的提升：

1、生产效率提高：舒适的环境减少了员工因高温导致的疲劳与间歇休息需求，整体生产效率提升约15%-20%；

2、产品品质优化：稳定的温湿度环境有利于缝纫面料保持适宜状态，减少因湿热引起的线迹变形或材料伸缩问题，提升了鞋类产品的工艺一致性与质量稳定性；

3、企业形象与招工吸引力增强：现代化、人性化的作业环境成为企业招工与留人的重要优势，助力企业可持续发展。

六、项目示范与行业应用延伸

本项目虽针对鞋业生产车间，但其环境改造思路与技术方案同样适用于其他劳动密集型产业及具有类似建筑结构的工业场所，如服装加工、电子组装、轻工包装等行业，以及各类高层高、大跨度的厂房空间。瑞峰射流工业空调系统在实现高效降温、精准控湿与节能运行方面的优势，为各类工业环境改善提供了可靠的技术路径与成熟解决方案。

1、 Project Background

The footwear production base is located in Xianjiang Town, Rui'an City, Zhejiang Province, on the southeast coast. It belongs to the subtropical monsoon climate zone with distinct four seasons, with hot and humid summers and mild and humid winters. The average annual temperature is about 17-18 ℃, and the highest temperature in summer can reach over 35 ℃. The average relative humidity is relatively high, especially during the rainy season and summer. The workshop is prone to problems such as stuffiness and poor air circulation, which pose significant challenges to the production environment and personnel comfort.

2、 Factory Structure and Workshop Overview

The factory building is a multi story reinforced concrete standard factory building, and the workshop area that needs ventilation and cooling renovation is about 2200 square meters, with a floor height of 5.5 meters. The workshop is mainly divided into sewing main area and auxiliary functional area (including sorting area, temporary storage and turnover area). The sewing area is densely packed with industrial sewing equipment. Although it does not generate obvious heat, there are about 280 long-term resident workers in the workshop, which belongs to a typical labor-intensive production scenario. Personnel heat dissipation becomes the main source of heat load inside the workshop.

3、 Original environment and motivation for renovation

Previously, the workshop relied solely on traditional fans for ventilation, which had limited air circulation and could not effectively reduce perceived temperature and control humidity. The high temperature and high humidity environment leads to poor work comfort and increased fatigue among employees, resulting in a high employee turnover rate in the long run. In order to enhance employee stability, improve working conditions, and ensure the sensitivity of fabrics and finished products to temperature and humidity during shoe production, the owner has decided to systematically upgrade the workshop environment.

4、 Scheme design and technical selection

The Ruifeng technical team has comprehensively considered multiple key factors, including:

(1). Geographical and climatic characteristics: In response to the high temperature and humidity of the local summer climate, it is necessary to strengthen the cooling and dehumidification capabilities;

(2). Factory structure conditions: Utilizing higher floors and adopting aerial installation methods to avoid occupying valuable ground production space;

(3). Workshop layout and heat source characteristics: Combining the characteristics of dense personnel and compact equipment arrangement, it is necessary to achieve long-distance and large-scale uniform air supply;

(4). System efficiency and energy-saving requirements: While ensuring refrigeration efficiency, control operating costs and improve overall energy efficiency.

Based on the above analysis, the high-power horizontal jet evaporative cooling industrial air conditioning system was ultimately selected. The device adopts a hanging installation, which not only saves the ground usage area, but also achieves long-distance air transportation and full coverage of the workshop through powerful jet air supply technology, effectively promoting air circulation and temperature balance.

5、 Implementation effect and efficiency improvement

After the system was put into use, the temperature and humidity of the entire workshop were accurately controlled, and the indoor temperature remained within a comfortable range of 26-28 ℃ in summer, with a significant decrease in relative humidity. Employees working in a cool and dry environment have significantly improved their physical comfort, increased their work enthusiasm and focus, and effectively alleviated the phenomenon of personnel turnover.

The improvement of production environment has further driven the enhancement of comprehensive benefits of enterprises:

(1). Improved production efficiency: A comfortable environment reduces employee fatigue and intermittent rest needs caused by high temperatures, resulting in an overall increase in production efficiency of about 15% -20%;

(2). Product quality optimization: A stable temperature and humidity environment is conducive to maintaining the appropriate state of sewing fabrics, reducing thread deformation or material stretching caused by humidity and heat, and improving the process consistency and quality stability of footwear products;

(3). Enhanced corporate image and recruitment appeal: A modern and humanized work environment has become an important advantage for companies to recruit and retain employees, helping them achieve sustainable development.

6、 Project Demonstration and Industry Application Extension

Although this project is aimed at shoe production workshops, its environmental renovation ideas and technical solutions are also applicable to other labor-intensive industries and industrial sites with similar building structures, such as clothing processing, electronic assembly, light industry packaging, and various high-rise, large-span factory spaces. The advantages of Ruifeng Jet Industrial Air Conditioning System in achieving efficient cooling, precise humidity control, and energy-saving operation provide reliable technical paths and mature solutions for improving various industrial environments.
