深圳光明电器厂大型离心式冷风机(SS-EAC系列) + 负压风机综合通风降温工程

【项目背景：身处“智造”热土，亟待环境升级】

本项目位于中国改革开放的前沿阵地——深圳。深圳地处南海之滨，属于典型的亚热带海洋性气候，夏季漫长且高温高湿，平均气温常超过30℃，相对湿度可达80%以上。作为“粤港澳大湾区”的核心城市，深圳更是全球电子信息产业的重镇，其所在的珠三角地区形成了规模宏大、链条完整的电子电器产业集群，素有“世界工厂”之称。

本案的客户便是这一集群中的一家专业制造型企业，主营网络产品、通讯设备、电脑周边、数字移动通信终端及家用电子器材等精密电子产品。此类产品在生产过程中，对生产环境的温湿度、空气洁净度及新风量有着严苛要求：

1、精密设备运行： SMT贴片机、注塑机等精密设备在运行时会产生大量热量，且对环境温湿度变化极为敏感，过高温度或湿度过大可能导致设备故障、精度下降。

2、产品质量保障： 焊接、封装、测试等工序需要在稳定、洁净的环境中进行。温度不均易导致焊接虚焊，湿度过高则可能引起电路板受潮、氧化，直接影响产品良率和长期可靠性。

3、员工舒适与健康： 车间内设备密集，散热大，加上建筑围护结构传热，夏季极易形成闷热环境，影响员工的工作效率与身心健康。

该工厂的车间位于一栋多层钢筋混凝土结构的标准厂房内，墙体为实心砖，窗户较少，整体密闭性较好，但面积较大，空气流通不畅，炎热季节车间内温度常居高不下，成为制约生产效率与产品质量的痛点。

【解决方案：因势利导，打造“1+1>2”的综合通风降温系统】

瑞峰环保制冷的技术团队在深入勘察现场后，综合考量了深圳地区高温高湿的气候特点、电子厂精密生产对环境的特殊要求、车间密闭且面积大的建筑结构、以及客户对节能环保的期望等多重因素，最终摒弃了传统“大而全”但能耗巨大的中央空调方案，也排除了仅靠风扇“治标不治本”的局部送风方式，创新性地设计了一套以“大功率不锈钢过滤冷风机(SS-EAC系列) + 负压风机”为核心的综合通风降温系统。

【方案核心：双剑合璧，诠释通风降温新理念】

1、主力降温源：大型离心式冷风机(SS-EAC系列) —— 大风量、远送风、耐腐蚀

作为降温系统的“心脏”，我们选用了大型离心式冷风机(SS-EAC系列)。该型产品有别于市场上普通的轴流式冷风机，其核心优势在于：

1）大风压，送风远： 采用离心式电机，能产生强大的静压，克服管道阻力，实现最长达200米的远距离送风，完美解决了大跨度车间冷气分布不均的问题。

2）大风量，全覆盖： 结合四面进风的5090型优质湿帘，换热面积大，降温效率高，单机即可覆盖广阔空间，确保车间内每一个角落都能感受到4-8℃的显著降温。

3）高强度，耐腐蚀： 机身采用不锈钢水箱并经过高强度烤漆处理，防锈耐冲击，能适应电子厂等工业环境中的复杂工况。可按需选配304不锈钢材质及防爆、过滤等特殊功能，满足不同区域的精细化需求。

2、关键辅助源：负压风机 —— 强力排风，破解湿度与闷热难题

冷风机在降温的同时会增加空气湿度，对于对湿度敏感的电子车间，我们巧妙地引入了负压风机作为“黄金搭档”。其工作原理基于空气对流与负压效应：

1）物理原理： 负压风机安装于车间一侧墙壁，开启后迅速将车间内高温、浑浊、潮湿的空气强力抽出，使室内形成“负压”状态。在气压差的作用下，室外新鲜空气会从另一侧的门窗或我们预留的进风口被强制补入，形成“抽拉式”的气流组织。

2）协同效应： 这种布局下，冷风机输送的冷空气并非简单地在车间内循环，而是沿着预设的路径被“拉”过整个车间，再被负压风机排出。这一过程不仅实现了高效的降温，更通过不断置换空气，有效降低了车间内的相对湿度，解决了单一使用冷风机可能导致的湿度过高问题，同时保证了车间内有源源不断的新鲜空气。

【项目成效：环境优化，品质与效能双提升】

系统投入使用后，车间环境得到了质的飞跃：

1、温湿度得到精准控制： 在炎热的夏季，车间内温度稳定维持在26-28℃的舒适区间，相对湿度也控制在适宜精密电子生产的范围内，为设备和产品提供了稳定的环境保障。

2、空气质量显著改善： 负压风机带来的强力通风，有效排除了生产过程中产生的烟尘、异味及设备散发的热量，车间内空气变得清新流通，员工普遍反映工作舒适度大幅提升。

3、产品质量与生产效率提高： 环境改善后，因温湿度问题导致的产品不良率明显下降，员工工作热情高涨，生产效率随之提升。

4、节能效益突出： 相比传统工业空调方案，该综合系统节省了约50%以上的运行电费，为客户带来了长期的经济效益，充分体现了“环保空调”的绿色价值。

Shenzhen Guangming Electric Appliance Factory Large Centrifugal Air Cooler (SS-EAC Series)+Negative Pressure Fan Comprehensive Ventilation and Cooling Project

【 Project Background: Located in the hotbed of "smart manufacturing", urgently in need of environmental upgrading 】

This project is located in Shenzhen, the forefront of China's reform and opening up. Shenzhen is located on the coast of the South China Sea and belongs to a typical subtropical maritime climate. The summer is long and characterized by high temperatures and humidity, with an average temperature often exceeding 30 ℃ and a relative humidity of over 80%. As the core city of the Guangdong Hong Kong Macao Greater Bay Area, Shenzhen is also a major hub of the global electronic information industry. The Pearl River Delta region where it is located has formed a large-scale and complete electronic and electrical industry cluster, known as the "world factory".

The client of this case is a professional manufacturing enterprise in this cluster, specializing in precision electronic products such as network products, communication equipment, computer peripherals, digital mobile communication terminals, and household electronic equipment. This type of product has strict requirements for the temperature, humidity, air cleanliness, and fresh air volume of the production environment during the production process

1. Precision equipment operation: SMT surface mount machines, injection molding machines, and other precision equipment generate a large amount of heat during operation and are extremely sensitive to changes in environmental temperature and humidity. Excessive temperature or humidity may lead to equipment failure and decreased accuracy.

2. Product quality assurance: Welding, packaging, testing and other processes need to be carried out in a stable and clean environment. Uneven temperature can easily lead to virtual soldering, while high humidity may cause the circuit board to become damp or oxidized, directly affecting product yield and long-term reliability.

3. Employee comfort and health: The equipment in the workshop is dense, with high heat dissipation, and coupled with the heat transfer of the building envelope, it is easy to form a hot and humid environment in summer, which affects the work efficiency and physical and mental health of employees.

The workshop of the factory is located in a standard multi story reinforced concrete structure, with solid brick walls and few windows. The overall airtightness is good, but the area is large and the air circulation is poor. During hot seasons, the temperature in the workshop often remains high, which becomes a pain point that restricts production efficiency and product quality.

【 Solution: Adapt to the situation and create a comprehensive ventilation and cooling system with "1+1>2" 】

After conducting an in-depth investigation of the site, the technical team of Ruifeng Environmental Protection Refrigeration comprehensively considered multiple factors such as the high temperature and high humidity climate characteristics in Shenzhen, the special environmental requirements of precision production in electronic factories, the enclosed and large building structure of workshops, and customers' expectations for energy conservation and environmental protection. Eventually, they abandoned the traditional "large and comprehensive" central air conditioning solution with huge energy consumption, and also eliminated the local air supply method of only relying on fans to "treat symptoms without addressing the root cause". They innovatively designed a comprehensive ventilation and cooling system with "high-power stainless steel filter air cooler (SS-EAC series)+negative pressure fan" as the core.

[Core of the plan: A combination of two swords, interpreting the new concept of ventilation and cooling]

1. Main cooling source: Large centrifugal air cooler (SS-EAC series) - high air volume, remote air supply, corrosion-resistant

As the "heart" of the cooling system, we have chosen a large centrifugal air cooler (SS-EAC series). This type of product is different from ordinary axial flow air coolers on the market, and its core advantages are:

1) High wind pressure, far air supply: Using a centrifugal motor, it can generate strong static pressure, overcome pipeline resistance, and achieve long-distance air supply up to 200 meters, perfectly solving the problem of uneven distribution of cold air in large-span workshops.

2) High air volume, full coverage: Combined with the 5090 high-quality wet curtain with four sided air intake, the heat exchange area is large and the cooling efficiency is high. A single machine can cover a wide space, ensuring that every corner of the workshop can feel a significant cooling of 4-8 ℃.

3) High strength and corrosion resistance: The body is made of stainless steel water tank and treated with high-strength paint, which is rust resistant and impact resistant, and can adapt to complex working conditions in industrial environments such as electronics factories. 304 stainless steel material and special functions such as explosion-proof and filtering can be selected as needed to meet the refined needs of different areas.

2. Key auxiliary source: Negative pressure fan - powerful exhaust, solves the problem of humidity and stuffiness

Air coolers increase air humidity while cooling down. For humidity sensitive electronic workshops, we cleverly introduce negative pressure fans as the "golden partner". Its working principle is based on air convection and negative pressure effect:

1) Physical principle: The negative pressure fan is installed on one side of the workshop wall, and when turned on, it quickly extracts the high-temperature, turbid, and humid air in the workshop, creating a "negative pressure" state indoors. Under the action of air pressure difference, fresh outdoor air will be forcibly replenished through the doors and windows on the other side or our reserved air inlet, forming a "pull-out" airflow organization.

2) Synergy effect: Under this layout, the cold air delivered by the air cooler is not simply circulated within the workshop, but is "pulled" through the entire workshop along a predetermined path and then discharged by the negative pressure fan. This process not only achieves efficient cooling, but also effectively reduces the relative humidity in the workshop by continuously replacing the air, solving the problem of high humidity that may be caused by the use of a single air cooler, while ensuring a continuous supply of fresh air in the workshop.

Project effectiveness: Environmental optimization, dual improvement of quality and efficiency

After the system was put into use, the workshop environment underwent a qualitative leap:

1. Temperature and humidity are precisely controlled: In the hot summer, the temperature in the workshop is maintained within a comfortable range of 26-28 ℃, and the relative humidity is also controlled within a suitable range for precision electronic production, providing a stable environmental guarantee for equipment and products.

2. Significant improvement in air quality: The strong ventilation brought by negative pressure fans effectively eliminates the smoke, odors, and heat emitted by equipment during the production process, making the air in the workshop fresh and circulating. Employees generally report a significant increase in work comfort.

3. Improvement in product quality and production efficiency: After environmental improvement, the defect rate of products caused by temperature and humidity issues has significantly decreased, and employees' enthusiasm for work has increased, resulting in an improvement in production efficiency.

4. Outstanding energy-saving benefits: Compared with traditional industrial air conditioning solutions, this comprehensive system saves more than 50% of operating electricity costs, bringing long-term economic benefits to customers and fully reflecting the green value of "environmentally friendly air conditioning".

【 Capability Extension: Not limited to electrical factories, providing customized solutions for multiple scenarios 】

This project is not only a successful practice for the electronic and electrical industry, but also a concentrated reflection of Ruifeng Environmental Protection's highly customized ability in "ventilation and cooling solutions+stainless steel air cooler products". Our technology link design and adaptation capabilities enable us to deeply explore customers' practical needs, ensuring high implementation of solutions and long-lasting product durability.

Based on the rich product line of SS-EAC series (such as filter type, mobile type, explosion-proof type, copper iron zinc free type, etc.), our business scope has successfully covered and expanded to the following similar scenarios:

1. Special Space Applications: For high cleanliness or special requirements working conditions such as new energy workshops, battery factories, food production workshops, etc., copper iron zinc free air coolers can be provided to strongly filter specific ions and ensure absolute safety in the production process.

2. High risk scenario application: For flammable and explosive places such as chemical workshops, dust workshops, mining sites, and oil and gas industries, explosion-proof air coolers can be provided, using high-grade accessories such as explosion-proof motors and controllers to eliminate safety hazards from the source.

3. Open/semi open space application: For places with high personnel gathering and mobility such as sports venues, logistics warehouses, exhibition sites, outdoor camps, and large stalls, mobile air coolers can be provided, which have the characteristics of plug and play, convenient mobility, and wide wind range, and can flexibly meet various temporary or semi permanent cooling needs.

Summary: From the successful case of Shenzhen Guangming Electric Appliance Factory, it can be seen that Ruifeng Environmental Protection Refrigeration always adheres to the inspection standards of "deep exploration of practical needs, high degree of implementation, and product durability". We not only provide a single product, but also strive to provide one-stop, in-depth ventilation and cooling solutions for industrial, commercial, and agricultural customers in all scenarios, from "scenario diagnosis" to "solution design" and then to "product customization".
