广东惠州某电子厂车间轴流式冷风机(SS-EAC系列) + 负压风机综合通风降温工程

【项目背景与客户痛点】

本项目位于广东省惠州市。惠州地处珠三角核心地带，属亚热带季风气候，夏季高温多雨，平均气温常达30℃以上，且湿度大、闷热时间长，对工业生产环境构成了严峻挑战。作为珠三角世界级电子信息产业带的重要一环，惠州及周边地区聚集了数以万计的电子电器企业，形成了从零部件到整机生产的完整产业链。该行业生产车间普遍对温度、洁净度及新风量有严苛要求：电子元器件在高温环境下易加速老化、影响性能稳定性；焊接、注塑等工序产生的微量烟尘与气味需快速排出；同时，高密度生产环境易造成氧气含量不足，影响员工身心健康与工作效率。

客户车间位于一栋多层钢筋混凝土结构的标准厂房内，整体密闭性较好，空间开阔但面积较大。由于建筑结构限制，自然通风效果不佳，夏季内部温度常年居高不下，湿气积聚，不仅影响了精密电子产品的良品率，也导致一线员工工作环境闷热难耐，人员流动率上升。因此，亟需一套高效、节能且切实可行的通风降温解决方案。

【瑞峰方案设计与核心思路】

瑞峰环保制冷的技术团队在实地勘测后，综合评估了多重关键因素：

1、地理位置与气候：针对惠州高温高湿的气候特点，方案需兼顾降温与除湿，避免单纯降温导致环境过于潮湿。

2、建筑结构与面积：厂房面积大、密闭性强，需要送风距离远、换气效率高的设备组合，以形成有效的气流组织。

3、行业特性：电子行业对生产环境的洁净度、温湿度稳定性有较高要求，方案需避免引入污染物，且不能干扰现有生产线布局。

4、经济性与能耗：需在保证效果的前提下，为客户提供比传统工业空调更节能、后期维护成本更低的方案。

基于上述分析，瑞峰设计团队摒弃了传统压缩机空调能耗巨大、安装成本高的方案，创新性地采用了“大功率不锈钢轴流式冷风机(SS-EAC系列) + 负压风机”的综合通风降温工程布局。这一组合充分发挥了两种设备的协同优势，实现“1+1>2”的效能。

【核心设备选型与技术优势】

1、轴流式冷风机(SS-EAC系列)：实现“大风量、大风压、远距离”送风

轴流式冷风机是SS-EAC系列中的一款核心机型，专为超大空间、远距离送风需求而设计。它基于水蒸发降温原理，通过高效5090型湿帘，将室外热空气进行等焓降温，再利用大功率离心电机高速旋转，产生强劲气流。与普通轴流风机不同，该机型内置导风板优化风道结构，风压更大、送风距离更远，最远管道送风可达200米，能够将降温后的湿润冷空气均匀输送到车间深处，有效覆盖传统方案难以触及的区域。同时，其不锈钢机身与烤漆工艺，确保了在工业环境下长期运行的防锈耐腐蚀能力，使用寿命远超常规产品。

2.、负压风机：构建“抽拉式”气流组织，破解湿度难题

冷风机在降温的同时会带入部分水汽，而南方夏季本身湿度较高，若单一使用冷风机，可能造成车间湿度过高，影响电子产品生产。为此，我们引入了负压风机系统。其原理是：在厂房一侧墙面安装负压风机，强力将室内高温、浑浊、潮湿的空气抽出，使室内形成瞬间的负压状态。在大气压强的作用下，室外新鲜空气会从另一侧安装的冷风机进风口被“拉”入车间。这种“抽拉式”的气流组织，不仅加速了空气的流通与换气，更巧妙地将冷风机带入的微量水汽迅速排出室外，有效平衡了温度与湿度，使车间环境始终保持干爽、清凉、富氧的状态。

【方案实施效果与价值】

设备启用后，车间环境发生了质的改变：

1、温湿度显著改善：在夏季最炎热时段，车间内平均温度降低4-8℃，相对湿度控制在舒适范围内，彻底告别闷热潮湿。

2、空气品质提升：每小时换气次数达到设计标准，焊接烟尘、化学气味被迅速排离，新鲜空气持续补充，员工普遍反映呼吸更顺畅、体感更舒适。

3、产品品质与生产效率双丰收：稳定的温湿度环境为电子元器件提供了可靠的储存与操作条件，有效降低了因高温导致的产品不良率。员工工作积极性和稳定性大幅提升，间接带动了产线效率的增长。

4、节能效益突出：与传统工业空调相比，该综合方案仅消耗约30%的电能，实现了高效降温与低碳运行的双重目标，为客户节约了可观的长期运营成本。

Integrated ventilation and cooling project of axial flow air cooler (SS-EAC series) and negative pressure fan in a certain electronic factory workshop in Huizhou, Guangdong Province

Project Background and Customer Pain Points

This project is located in Huizhou City, Guangdong Province. Huizhou is located in the core area of the Pearl River Delta, with a subtropical monsoon climate. It experiences high temperatures and heavy rainfall in summer, with an average temperature often exceeding 30 ℃. Additionally, it has high humidity and long periods of stuffiness, posing a severe challenge to the industrial production environment. As an important part of the world-class electronic information industry belt in the Pearl River Delta, Huizhou and surrounding areas have gathered tens of thousands of electronic and electrical enterprises, forming a complete industrial chain from parts to whole machine production. The production workshops in this industry generally have strict requirements for temperature, cleanliness, and fresh air volume: electronic components are prone to accelerated aging and affect performance stability in high temperature environments; Trace amounts of smoke and odors generated during welding, injection molding, and other processes need to be quickly eliminated; At the same time, high-density production environments can easily lead to insufficient oxygen content, affecting the physical and mental health and work efficiency of employees.

The customer workshop is located in a standard multi story reinforced concrete structure factory building, with good overall airtightness and spacious but large area. Due to the limitations of the building structure and poor natural ventilation, the internal temperature remains high throughout the summer, and moisture accumulates. This not only affects the yield of precision electronic products, but also leads to a hot and humid working environment for frontline employees, resulting in an increase in personnel turnover. Therefore, there is an urgent need for an efficient, energy-saving, and practical ventilation and cooling solution.

Ruifeng Plan Design and Core Ideas

After on-site investigation, the technical team of Ruifeng Environmental Protection Refrigeration comprehensively evaluated multiple key factors:

1. Geographical location and climate: In response to the high temperature and high humidity climate characteristics of Huizhou, the plan needs to take into account both cooling and dehumidification to avoid excessive humidity caused by simple cooling.

2. Building structure and area: The factory has a large area and strong airtightness, requiring a combination of equipment with long air supply distance and high ventilation efficiency to form effective airflow organization.

3. Industry characteristics: The electronics industry has high requirements for the cleanliness and temperature and humidity stability of the production environment. The solution needs to avoid introducing pollutants and cannot interfere with the existing production line layout.

4. Economy and energy consumption: We need to provide customers with a more energy-efficient and lower maintenance cost solution than traditional industrial air conditioners while ensuring effectiveness.

Based on the above analysis, the Ruifeng design team abandoned the traditional compressor air conditioning solution with huge energy consumption and high installation costs, and innovatively adopted a comprehensive ventilation and cooling engineering layout of "high-power stainless steel axial flow air cooler (SS-EAC series)+negative pressure fan". This combination fully leverages the collaborative advantages of the two devices, achieving the efficiency of "1+1>2".

Core equipment selection and technological advantages

1. Axial flow air cooler (SS-EAC series): achieving "high air volume, high air pressure, long-distance" air supply

Axial flow air cooler is a core model in the SS-EAC series, designed specifically for large space and long-distance air supply needs. It is based on the principle of water evaporation cooling, using an efficient 5090 type wet curtain to isentropic cool outdoor hot air, and then utilizing a high-power centrifugal motor to rotate at high speed, generating strong airflow. Unlike ordinary axial flow fans, this model has a built-in air guide plate to optimize the air duct structure, resulting in higher air pressure and longer air supply distance. The farthest pipeline can supply air up to 200 meters, which can evenly transport the cooled moist cold air to the deep parts of the workshop, effectively covering areas that are difficult to reach with traditional solutions. At the same time, its stainless steel body and baking paint process ensure long-term rust and corrosion resistance in industrial environments, with a service life far exceeding that of conventional products.

2. Negative pressure fan: Build a "pull-out" airflow organization to solve the problem of humidity

Air coolers bring in some moisture while cooling down, and the humidity in the southern summer is relatively high. If only air coolers are used, it may cause high humidity in the workshop, affecting the production of electronic products. For this purpose, we have introduced a negative pressure fan system. The principle is to install a negative pressure fan on one side of the factory wall, which forcefully extracts the high-temperature, turbid, and humid air indoors, creating an instantaneous negative pressure state. Under the influence of atmospheric pressure, fresh outdoor air will be "pulled" into the workshop through the air inlet of the air cooler installed on the other side. This "pull-out" airflow organization not only accelerates the circulation and ventilation of air, but also cleverly discharges the trace water vapor brought in by the air cooler quickly outside, effectively balancing temperature and humidity, and keeping the workshop environment dry, cool, and rich in oxygen at all times.

Implementation effect and value of the plan

After the equipment was put into use, there was a qualitative change in the workshop environment:

1. Significant improvement in temperature and humidity: During the hottest period of summer, the average temperature in the workshop decreases by 4-8 ℃, and the relative humidity is controlled within a comfortable range, completely bidding farewell to stuffiness and humidity.

2. Air quality improvement: The air exchange rate per hour meets the design standards, welding fumes and chemical odors are quickly removed, fresh air is continuously replenished, and employees generally report smoother breathing and a more comfortable feeling.

3. Double harvest of product quality and production efficiency: The stable temperature and humidity environment provides reliable storage and operation conditions for electronic components, effectively reducing the product defect rate caused by high temperature. The significant improvement in employee work enthusiasm and stability has indirectly driven the growth of production line efficiency.

4. Outstanding energy-saving benefits: Compared with traditional industrial air conditioning, this comprehensive solution only consumes about 30% of electricity, achieving the dual goals of efficient cooling and low-carbon operation, and saving customers considerable long-term operating costs.

Ruifeng's ability extension: not limited to the electronics industry, deeply adaptable to all scenarios
