【 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.
