一、 项目背景与挑战

本工程位于浙江省。浙江地处华东沿海，属亚热带季风气候，夏季高温持续时间长，且湿度较大，闷热天气对生产一线的员工是极大的考验。该企业是一家大型制造型企业，生产车间面积近5000平方米，层高达12米，为典型的彩钢结构厂房。车间内虽无大型发热设备，但生产工位密集，工人数量众多。在夏季，因彩钢瓦吸热和人体自身散热，车间内易形成高温闷热、空气流通不畅的环境，不仅严重影响工人的工作舒适度与效率，更可能成为安全生产的隐患。因此，改善车间作业环境，为员工提供清凉、清新的工作空间，成为企业亟需解决的问题。

二、 瑞峰定制化解决方案

针对该项目的特殊性，瑞峰方案设计团队进行了全方位的综合考量。首先，从地理因素出发，充分考虑浙江地区夏季高温高湿的气候特点；其次，深入分析车间结构，近5000平米的大跨度、12米层高及彩钢材质，决定了传统空调方案能耗巨大；再次，站在企业成本角度，既要控制初期设备投入，更要算好长期的“节能账”。

项目初期，企业曾考虑安装传统工业空调。但瑞峰专业人员经过现场勘查与数据分析后指出：在如此大空间、高挑空的结构下，传统空调要达到理想的降温效果，不仅设备采购成本高昂，后期的电费和维护费用更是一笔难以承受的持续支出，性价比极低。

为此，我们向客户推荐了“冷风机+负压风机”的组合式通风降温方案。这一方案的核心理念是利用流体力学原理，形成“强制进风+强力排风”的立体空气循环系统。冷风机安装于车间一侧，利用水蒸发吸热原理，将室外的新鲜空气过滤降温后，源源不断地向车间内输送大量的冷风、鲜风；与此同时，负压风机安装于车间另一侧，以强大的排风能力迅速将室内的热气、浊气、异味强制排出室外。两者一送一排，在车间内形成一道无形的“空气对流墙”，使整个空间产生3-5次/小时的换气次数，快速建立起一个微正压或负压的清新环境。相比传统空调，这套组合方案的投资成本降低约50%，运行能耗仅为空调的1/8左右，真正实现了“降本增效”，为企业提供了最优性价比的选择。

三、 卓越成效与客户体验

设备启用后，车间环境发生了立竿见影的改善。得益于冷风机持续输送的湿润新鲜空气与负压风机的高效排风，车间内部形成了高效的气流组织。空气从冷风机的出风口开始，像一道无形的“风墙”匀速推进，有效稀释并驱散了聚集在工位附近的浑浊空气和人体热量。实测显示，车间内平均温度可降低4-8℃，且空气流动速度维持在人体感觉最舒适的0.5-1.5米/秒之间，体感温度下降尤为明显。员工们普遍反映，以往夏季作业时的闷热感、头昏感彻底消失，工作环境变得清凉通透，心情也随之舒畅，生产效率得到显著提升。

四、 场景延伸与能力体现

此次为浙江XX制造企业实施的工程项目，虽然面对的是生产车间，但其解决方案的成功应用，也充分印证了“冷风机+负压风机”组合模式在其他类似场景下的广泛适用性。如大型仓储物流中心、高温铸造车间、人员密集的食堂/礼堂、以及有异味或粉尘困扰的特殊作业空间等，均可参考此成功模式。

通过此项目，瑞峰公司再次证明了我们在大空间、特殊行业要求下的专业能力。我们不仅提供设备，更擅长结合实地工况、建筑结构、用户预算及行业特性，为客户量身定制综合选型与方案设计，确保每一个通风降温工程都能达到效果、成本与节能的最佳平衡，以专业力量助力企业发展。

Zhejiang XX Manufacturing Enterprise Production Workshop Cold Air Fan+Negative Pressure Fan Ventilation and Cooling Project

1、 Project Background and Challenges

This project is located in Zhejiang Province. Zhejiang is located along the coast of East China and has a subtropical monsoon climate. The high temperatures in summer last for a long time, and the humidity is high. The hot and humid weather is a great challenge for employees on the production line. This enterprise is a large manufacturing enterprise with a production workshop area of nearly 5000 square meters and a floor height of 12 meters. It is a typical color steel structure factory building. Although there are no large heating equipment in the workshop, the production workstations are dense and there are many workers. In summer, due to the heat absorption of color steel tiles and the body's own heat dissipation, the workshop is prone to creating a hot and humid environment with poor air circulation, which not only seriously affects the comfort and efficiency of workers, but also may become a hidden danger to safety production. Therefore, improving the working environment in the workshop and providing employees with cool and fresh workspaces has become an urgent problem that enterprises need to solve.

2、 Ruifeng customized solution

In response to the particularity of this project, the Ruifeng design team has conducted a comprehensive consideration from all aspects. Firstly, starting from geographical factors, fully consider the climate characteristics of high temperature and humidity in Zhejiang region during summer; Secondly, in-depth analysis of the workshop structure reveals that the nearly 5000 square meters of large-span, 12 meter floor height, and color steel material determine the huge energy consumption of traditional air conditioning solutions; Once again, from the perspective of enterprise costs, it is necessary to not only control the initial equipment investment, but also calculate the long-term "energy-saving account".

At the beginning of the project, the company considered installing traditional industrial air conditioning. However, after on-site investigation and data analysis, Ruifeng professionals pointed out that in such a large space and high ceiling structure, traditional air conditioners need to achieve ideal cooling effects. Not only is the equipment procurement cost high, but the later electricity and maintenance costs are also an unbearable continuous expense, with extremely low cost-effectiveness.

For this reason, we recommend a combined ventilation and cooling solution of "air cooler+negative pressure fan" to our customers. The core concept of this plan is to utilize the principles of fluid mechanics to form a three-dimensional air circulation system of "forced intake+strong exhaust". The air cooler is installed on one side of the workshop, using the principle of water evaporation to absorb heat. After filtering and cooling the fresh air outside, it continuously delivers a large amount of cold and fresh air to the workshop; At the same time, the negative pressure fan is installed on the other side of the workshop, with strong exhaust capacity to quickly force the hot air, turbid air, and odors indoors out of the room. The two are arranged in a row, forming an invisible "air convection wall" in the workshop, which generates 3-5 air changes per hour in the entire space, quickly establishing a fresh environment with slight positive or negative pressure. Compared to traditional air conditioning, this combination solution reduces investment costs by about 50% and operates at only about 1/8 of the energy consumption of air conditioning, truly achieving "cost reduction and efficiency improvement" and providing enterprises with the best cost-effective choice.

3、 Excellent performance and customer experience

After the equipment was put into use, there was an immediate improvement in the workshop environment. Thanks to the continuous supply of moist fresh air by the air cooler and the efficient exhaust of the negative pressure fan, an efficient airflow organization is formed inside the workshop. The air starts from the outlet of the air cooler and moves at a constant speed like an invisible "wind wall", effectively diluting and dispersing the turbid air and human body heat gathered near the workstation. Actual tests have shown that the average temperature in the workshop can be reduced by 4-8 ℃, and the air flow velocity is maintained between 0.5-1.5 meters per second, which is the most comfortable for human perception. The perceived temperature drop is particularly significant. Employees generally reported that the stuffiness and dizziness that used to occur during summer work have completely disappeared, and the working environment has become cool and transparent, with a relaxed mood and a significant improvement in production efficiency.

4、 Scene extension and ability manifestation

The engineering project implemented for XX manufacturing enterprise in Zhejiang this time, although facing the production workshop, the successful application of its solution fully confirms the wide applicability of the "cold air fan+negative pressure fan" combination mode in other similar scenarios. This successful model can be applied to large warehousing and logistics centers, high-temperature casting workshops, densely populated canteens/auditoriums, as well as special work spaces that are plagued by odors or dust.

Through this project, Ruifeng Company has once again demonstrated our professional capabilities in large spaces and special industry requirements. We not only provide equipment, but also specialize in combining on-site conditions, building structures, user budgets, and industry characteristics to tailor comprehensive selection and scheme design for customers, ensuring that every ventilation and cooling project can achieve the best balance between effectiveness, cost, and energy conservation, and using professional strength to assist enterprise development.
