【工程案例】奔驰汽车展会布置现场移动机扇应用项目

【项目背景：依托“中国第一展”的临时盛会】

本项目位于风景秀丽的广州会展公园内，与享誉全球的中国进出口商品交易会（简称：广交会） 展馆——琶洲广交会展馆仅一步之遥。

1、区位与气候分析： 广州地处亚热带，属于典型的海洋性亚热带季风气候，4月至11月通常高温、多雨、闷热。尤其是户外或半户外空间，即便在春秋季，体感温度也常常远超实际气温，空气湿度大，风速低，容易让人感到闷热难耐。

2、依托广交会的影响力： 作为“中国第一展”，广交会期间汇聚了全球数十万的客商。此次奔驰选址在毗邻广交会展馆的公园内布展，不仅是为了服务本地客户，更是为了依托广交会巨大的国际流量，向世界展示其品牌形象。在这样一个国际化的舞台上，临时展厅的舒适度，直接影响着高端品牌的质感与访客的体验。

【项目挑战：临时建筑的通风降温难题】

车展方在公园草坪上临时搭建了一座钢架结构、透明塑料围蔽的防雨防风大棚。这种设计虽具有不遮挡周边自然景观、搭建撤展灵活的优点，但也给室内环境带来了巨大挑战：

1、“温室效应”显著： 透明塑料材质虽然透光，但在日照下会迅速吸收太阳辐射热量，导致棚内温度急剧上升，如同一个巨大的温室。

2、结构密闭且临时： 该结构无法安装传统固定的中央空调管道，且为了防雨防风，四周相对密闭，空气无法自然对流，导致内部热气、湿气聚集。

3、对设备的严苛要求： 传统空调成本高、安装周期长，且巨大的冷量容易在透明棚顶产生冷凝水；而固定式工业风扇又无法适应这种临时建筑的灵活性需求。

【瑞峰方案：移动机扇组合，灵活破解闷热困局】

面对上述多重因素（地理环境的湿热、临时建筑的隔热差、布展时间紧迫、设备成本控制以及对未来场地无破坏的要求），瑞峰环保制冷的方案设计人员提出了“移动离心式冷风机+移动工业级大风扇”的组合方案。选择这一方案的核心原因如下：

1、应对不确定的人流：全“移动”式布局

车展现场人流高峰低谷波动极大。我们选用的移动机型自带万向脚轮，无需安装，即插即用。在人流密集时可推至重点区域强化降温，活动结束后可随时移走腾出空间，实现了设备随需而动，资源零浪费。

2、匹配开放式空间：低成本实现“大自然风”

该大棚属于半开放式空间，传统密闭式空调并不适用。我们部署的离心式冷风机利用“水蒸发吸热”的自然物理原理（通过水幕循环冷却空气，再由风机送出比室温低4-8℃的冷风），而工业级永磁无级调速大风扇则通过大直径叶片慢速旋转，产生大面积的立体自然风。

物理原理揭秘： 冷风机送出的湿润冷风，配合大风扇产生的强劲气流，能迅速带走人体皮肤表面的湿热汗液，达到“体感降温”的神奇效果。这种“自然风”不仅凉爽，而且富含新鲜空气，完全避免了空调长时间吹拂带来的不适感。

3、极致改善体验：打造健康舒适的车展环境

方案实施后，大功率的冷风机与风扇协同工作，极大地改善了风量覆盖区域的空气流动。原本闷热的大棚内，取而代之的是清新、流动、凉爽的“自然风”。访客在欣赏奔驰汽车的同时，能感受到如置身林荫般的舒适，身心愉悦。这种对细节的关注，极大地提升了品牌的亲和力与展位的停留率。

4、经济高效，施工零干扰

整套方案无需铺设管道、无需电力增容，设备到场即开即用。展会结束后，设备可整体撤走用于下一个项目，不仅设备成本低，更节省了大量的安装与拆除开支。

【案例延伸与价值体现】  

此次虽是针对临时汽车展会的项目，但类似的场景应用广泛存在：

1、户外大型活动：如音乐节、发布会、户外婚礼；

2、临时厂房/仓储：季节性生产车间的防暑；

3、大型体育馆/展览馆：局部区域补风降温；

4、商业户外餐饮：大排档、露天咖啡座等。

本次项目的成功，不仅展示了奔驰品牌对客户体验的极致追求，也充分证明了瑞峰环保制冷在应对“特殊空间、特殊使用场景”时的专业实力。我们不仅懂得通风降温的物理原理，更懂得如何在复杂的制约因素（空间、成本、时效）下，进行设备的综合选型与方案设计，最终为客户实现“花小钱，办大事”的理想降温效果。选择瑞峰，即选择灵活、高效、省心的专业服务。

【 Engineering Case 】 Mercedes Benz Auto Exhibition Layout Site Mobile Fan Application Project

【 Project Background: A temporary event based on the "China's First Exhibition" 】

This project is located in the beautiful Guangzhou Convention and Exhibition Park, just a stone's throw away from the globally renowned China Import and Export Fair (Canton Fair) Complex - Pazhou Canton Fair Complex.

1. Location and climate analysis: Guangzhou is located in the subtropical zone and belongs to a typical maritime subtropical monsoon climate. From April to November, it is usually hot, rainy, and humid. Especially in outdoor or semi outdoor spaces, even in spring and autumn, the perceived temperature often far exceeds the actual temperature, with high air humidity and low wind speed, which can easily make people feel stuffy and unbearable.

2. Relying on the influence of the Canton Fair: As the "number one exhibition in China", the Canton Fair attracted hundreds of thousands of global merchants. The location of Mercedes Benz's exhibition in the park adjacent to the Canton Fair is not only to serve local customers, but also to showcase its brand image to the world by relying on the huge international traffic of the Canton Fair. On such an international stage, the comfort of temporary exhibition halls directly affects the texture of high-end brands and the experience of visitors.

Project Challenge: Ventilation and Cooling Difficulties in Temporary Buildings

The car exhibition team temporarily built a rainproof and windproof greenhouse with a steel frame structure and transparent plastic enclosure on the park lawn. Although this design has the advantages of not obstructing the surrounding natural landscape and being flexible in building and dismantling, it also brings huge challenges to the indoor environment:

1. The greenhouse effect is significant: although transparent plastic materials are translucent, they quickly absorb solar radiation heat under sunlight, causing the temperature inside the greenhouse to rise sharply, like a huge greenhouse.

2. Sealed and temporary structure: This structure cannot install traditional fixed central air conditioning ducts, and in order to prevent rain and wind, the surroundings are relatively sealed, preventing natural air convection and leading to the accumulation of hot and humid air inside.

3. Strict requirements for equipment: Traditional air conditioners have high costs, long installation cycles, and the huge cooling capacity can easily generate condensation water on transparent roofs; However, fixed industrial fans cannot meet the flexibility requirements of such temporary buildings.

Ruifeng Solution: Mobile fan combination, flexible solution to solve hot and humid situations

Faced with multiple factors such as the humid and hot geographical environment, poor insulation of temporary buildings, tight exhibition time, equipment cost control, and the requirement for future site integrity, the design team of Ruifeng Environmental Protection Refrigeration proposed a combination of "mobile centrifugal air coolers+mobile industrial grade large fans". The core reasons for choosing this plan are as follows:

1. Dealing with uncertain crowds: a fully "mobile" layout

The flow of people at the auto show fluctuates greatly during peak and off peak periods. The mobile model we have chosen comes with universal casters, which do not require installation and are plug and play. When the crowd is dense, it can be pushed to key areas to strengthen cooling. After the activity is over, it can be moved away at any time to free up space, achieving equipment on-demand and zero waste of resources.

2. Matching open spaces: low-cost implementation of 'natural wind'

This greenhouse belongs to a semi open space, and traditional closed air conditioning is not suitable. The centrifugal air cooler we deploy utilizes the natural physics principle of "water evaporation absorbs heat" (circulating air through a water curtain, and then sending out cold air 4-8 ℃ lower than room temperature by a fan), while the industrial grade permanent magnet infinitely variable speed large fan generates a large area of three-dimensional natural wind through the slow rotation of large-diameter blades.

Physics principle revealed: The moist cold air sent out by the air cooler, combined with the strong airflow generated by the large fan, can quickly remove the damp and hot sweat on the surface of the human skin, achieving the magical effect of "perceived cooling". This' natural wind 'is not only cool, but also rich in fresh air, completely avoiding the discomfort caused by prolonged air conditioning blowing.

3. Ultimate Improvement Experience: Creating a Healthy and Comfortable Auto Show Environment

After the implementation of the plan, high-power air coolers and fans work together to greatly improve the airflow in the coverage area. The originally stuffy greenhouse has been replaced by a fresh, flowing, and cool 'natural breeze'. Visitors can enjoy the comfort and physical pleasure of being surrounded by trees while admiring Mercedes Benz cars. This attention to detail greatly enhances the brand's affinity and booth retention rate.

4. Economically efficient, zero interference in construction

The entire solution does not require laying pipelines or increasing power capacity, and the equipment can be used immediately upon arrival. After the exhibition, the equipment can be removed as a whole for the next project, which not only reduces equipment costs but also saves a lot of installation and dismantling expenses.

Case Extension and Value Reflection

Although this is a project aimed at temporary car exhibitions, similar scenarios are widely used:

1. Outdoor large-scale events such as music festivals, press conferences, and outdoor weddings;

2. Temporary factory/warehouse: heatstroke prevention for seasonal production workshops;

3. Large sports venues/exhibition halls: local area ventilation and cooling;

4. Commercial outdoor dining: street stalls, outdoor cafes, etc.

The success of this project not only demonstrates the Mercedes Benz brand's ultimate pursuit of customer experience, but also fully demonstrates the professional strength of Ruifeng Environmental Protection Refrigeration in dealing with "special spaces and special usage scenarios". We not only understand the physical principles of ventilation and cooling, but also know how to comprehensively select equipment and design solutions under complex constraints such as space, cost, and timeliness, ultimately achieving the ideal cooling effect of "spending little money, doing big things" for customers. Choosing Ruifeng means choosing flexible, efficient, and worry free professional services.
