【项目背景】

近日，瑞峰环保制冷成功完成了对福建莆田荔城区知名鞋企——XX鞋业多个生产车间的通风降温工程改造。该项目涉及面积广、施工难度大，是我司在大空间厂房通风降温领域的又一标杆力作。

【项目地点及客户概况】

该企业位于福建莆田荔城区。莆田地处东南沿海，属典型的亚热带海洋性季风气候，全年温暖湿润，夏季漫长且高温高湿，7月至9月平均气温往往超过30℃，车间内极易产生闷热感。作为“中国鞋都”的核心区域，荔城区鞋业产业发达，该企业作为当地规模企业，拥有从原材料裁切到成品包装的完整制鞋全流程生产工艺，涵盖裁料、针车、贴合、成型、质检等环节。

【项目难点与需求】

该企业的新厂房为新建不久的五层钢筋混凝土结构标准厂房，每层建筑面积超10000平方米，层高达5米，单层面积超大。墙面虽设有玻璃窗采光，但自然通风能力有限。

本次需要改善环境的区域主要为裁料车间、针车流水线车间、贴合组装车间及质检包装车间。这些区域普遍存在两大痛点：

人员密集：设备与操作工位密集，人体散热和机器余热叠加，导致室内温度远高于室外。

空气污浊：特别是在贴合工序区域，生产过程中使用的胶合剂会挥发出有害气体，若无法及时排出，将严重影响一线工人的身体健康与生产效率。

【瑞峰解决方案】

针对该厂房“面积超大、层高较高、污染源集中”的特点，瑞峰的专业方案设计团队经过现场勘测与综合计算，摒弃了传统高能耗方案，量身定制了一套以“蒸发冷风机+负压排风”为核心的通风降温系统。

针对性的设备选型与布局

考虑到厂区地理环境、厂房超大跨度以及内部操作设备密集等因素，我们决定采用大功率蒸发式冷风机。其核心原理是利用水蒸发吸热的物理特性，对空气进行高效降温。我们设计了一套送风距离远的集中式风管网络，通过长风管+多风口的布局，将经过降温的新鲜冷风精准输送至每一个人员工位，确保覆盖无死角。

巧妙的安装方式

鉴于车间内生产设备已占满大部分地面空间，且不能影响物料流转，我们创新性地采用了墙外吊挂式安装。此举既不占用宝贵的生产地面面积，又能保证设备从室外吸入新鲜空气，经降温后源源不断送入车间内部。

科学的气流组织

为了配合新风输入并彻底改善空气质量，我们在墙体另一侧合理规划并安装了大排量的负压风机。通过设定科学的换气次数，形成强大的“新风推、浊气抽”的气流通道，迅速将贴合工序产生的胶合有害气体以及设备运行产生的热量排出室外，让车间始终保持空气清新流通。

【为什么选择瑞峰方案？】

起初，厂方曾考虑安装具备除湿功能的传统工业空调。瑞峰的专业人员从实际运营角度出发，为客户进行了深入的利弊分析：

虽然新厂房密封性好，理论上适合空调，但当前国内制鞋业已进入微利时代，工业空调高昂的设备购置成本以及巨大的电费消耗，将给企业带来沉重的长期负担。

相比之下，瑞峰推荐的蒸发冷风机方案虽然降温幅度不如空调（通常降温4-10℃），但通过科学的物理原理运用，利用大风量置换与风速带来的体感降温效应，能有效带走人体表面的热量，大幅降低“体感温度”。

方案实施后，车间内不再闷热憋气，空气变得清新流通。工人们在舒适的环境中工作，烦躁感降低，注意力更集中，不仅身心愉悦，企业的生产效率也得到了显著提升。 这种“以较小的投入换取最大的舒适度”的解决方案，其极致性价比最终赢得了客户的深度认可。

【项目延伸价值】

瑞峰此次服务的虽是鞋业工程，但该解决方案具有极强的可复制性。无论是同样面临人员密集、空间巨大、有异味或热量散发的电子装配车间、制衣纺织厂房、食品加工车间，还是仓储物流中心，瑞峰环保制冷都能凭借专业的经验，为您提供科学的通风降温方案。

我们不仅具备面对超大空间进行设备综合选型与精细化方案设计施工的能力，更重要的是，我们始终站在客户角度，切实考虑设备投入产出比与长期运营成本，致力于为您打造既实用又省钱的生产环境优化方案。

[Project Background]

Recently, Ruifeng Environmental Protection Refrigeration successfully completed the ventilation and cooling project renovation of multiple production workshops of XX Footwear, a well-known shoe enterprise in Licheng District, Putian, Fujian. This project involves a wide area and is difficult to construct, making it another benchmark work of our company in the field of ventilation and cooling for large space factories.

Project Location and Customer Overview

The enterprise is located in Licheng District, Putian, Fujian. Putian is located on the southeast coast and belongs to a typical subtropical maritime monsoon climate. It is warm and humid all year round, with long and high temperature and humidity summers. The average temperature from July to September often exceeds 30 ℃, making it easy to feel stuffy and hot in the workshop. As the core area of the "Shoe Capital of China", Licheng District has a developed footwear industry. As a local scale enterprise, this enterprise has a complete production process for shoemaking from raw material cutting to finished product packaging, covering cutting, sewing, bonding, molding, quality inspection and other links.

Project Difficulties and Requirements

The new factory building of the enterprise is a newly built five story reinforced concrete structure standard factory building, with a building area of over 10000 square meters per floor and a height of 5 meters per floor, with a single floor area that is extremely large. Although the wall is equipped with glass windows for natural lighting, its natural ventilation capacity is limited.

The areas that need to improve the environment this time are mainly the cutting workshop, needle car assembly line workshop, bonding assembly workshop, and quality inspection packaging workshop. There are generally two major pain points in these areas:

Personnel density: The equipment and operating workstations are densely packed, and the combination of human body heat dissipation and machine waste heat causes indoor temperatures to be much higher than outdoor temperatures.

Air pollution: Especially in the bonding process area, the adhesive used in the production process will emit harmful gases. If not discharged in a timely manner, it will seriously affect the physical health and production efficiency of frontline workers.

Ruifeng Solution

In response to the characteristics of the factory building, such as large area, high floor height, and concentrated pollution sources, Ruifeng's professional design team has abandoned the traditional high energy consumption plan through on-site investigation and comprehensive calculation, and tailored a ventilation and cooling system with "evaporative cold air fan+negative pressure exhaust" as the core.

Targeted equipment selection and layout

Considering the geographical environment of the factory area, the large span of the factory building, and the dense internal operating equipment, we have decided to use high-power evaporative air coolers. The core principle is to efficiently cool the air by utilizing the physical property of water evaporation absorbing heat. We have designed a centralized air duct network with a long air supply distance. Through the layout of long air ducts and multiple air outlets, the cooled fresh air is accurately delivered to each personnel workstation, ensuring coverage without blind spots.

Clever installation method

Considering that the production equipment in the workshop has occupied most of the ground space and cannot affect material flow, we innovatively adopted a wall mounted hanging installation. This move not only does not occupy valuable production floor area, but also ensures that the equipment can draw in fresh air from the outside and continuously send it into the workshop after cooling.

Scientific Airflow Organization

In order to accommodate the input of fresh air and thoroughly improve air quality, we have planned and installed a large displacement negative pressure fan on the other side of the wall. By setting a scientific air exchange rate, a powerful "fresh air push and turbid air extraction" airflow channel is formed to quickly remove harmful adhesive gases generated by the bonding process and the heat generated by equipment operation from the outside, ensuring that the workshop always maintains fresh and ventilated air.

Why choose the Ruifeng solution

At first, the factory considered installing traditional industrial air conditioners with dehumidification function. Ruifeng's professionals have conducted in-depth cost-benefit analysis for customers from a practical operational perspective

Although the new factory building has good sealing and is theoretically suitable for air conditioning, the domestic footwear industry has entered a low profit era. The high equipment purchase cost and huge electricity consumption of industrial air conditioning will bring a heavy long-term burden to the enterprise.

In contrast, the evaporative air cooler solution recommended by Ruifeng may not have the same cooling range as air conditioning (usually cooling by 4-10 ℃), but through the application of scientific physical principles, it can effectively remove the heat on the surface of the human body and significantly reduce the "perceived temperature" by utilizing the sensory cooling effect caused by high air volume displacement and wind speed.

After the implementation of the plan, the workshop will no longer be stuffy and stuffy, and the air will become fresh and well ventilated. Workers work in a comfortable environment, with reduced irritability and more focused attention. Not only are they physically and mentally happy, but the production efficiency of the enterprise has also been significantly improved. This solution of "exchanging maximum comfort with minimal investment" has ultimately won deep recognition from customers for its ultimate cost-effectiveness.

Project Extension Value

Although Ruifeng is providing services in the footwear industry, this solution has strong replicability. Whether it is an electronic assembly workshop, clothing and textile factory, food processing workshop, or warehousing and logistics center that also faces personnel density, huge space, odor or heat dissipation, Ruifeng Environmental Protection Refrigeration can provide you with scientific ventilation and cooling solutions with professional experience.

We not only have the ability to comprehensively select equipment and design and construct refined solutions for large spaces, but more importantly, we always stand from the customer's perspective, consider the input-output ratio of equipment and long-term operating costs, and are committed to creating practical and cost-effective production environment optimization solutions for you.
