Project Background and Customer Profile

The enterprise is located in Zhaoqing, Guangdong, which has a developed manufacturing industry. Zhaoqing is located in the subtropical monsoon climate zone, with long and high temperature and humidity summers, and mild and humid winters. The annual average temperature is high, and the relative humidity of the air is above 75% throughout the year. This "humid and hot" climate characteristic makes it easy for the production workshop to experience stuffiness and poor air circulation, posing a serious challenge to the working environment of frontline production workers.

This enterprise is a high-tech enterprise specializing in the production of precision plastics and hardware products. Plastic products cover processes such as injection molding and blow molding, while hardware products involve processes such as stamping and die-casting. The production of such products has high requirements for environmental temperature and air circulation - excessively high temperatures not only affect the comfort and efficiency of operators, but may also lead to poor heat dissipation of injection molding equipment, affecting the accuracy of product shaping.

Workshop Status and Design Challenges

The customer's production workshop is a large color steel shed structure with the following characteristics:

1. Spacious: The total area of the workshop is about 12000 square meters, with a floor height of about 20 meters, which is a typical tall space.

2. Architectural features: The walls and roof are made of color steel tiles with insulation layers, and the walls are complemented by large areas of lighting windows. Although this structure has a short construction period and controllable cost, its airtightness is relatively poor, and heat is easily radiated from the roof and walls.

3. Complex process: There is a complete plastic and hardware production line internally, covering the entire process from raw material melting, injection molding/stamping to cooling and assembly. The production equipment is dense, and multiple overhead cranes are operating at an altitude of about 17 meters, occupying a large amount of headspace.

Ruifeng Plan: Tailored and Precise Implementation

Faced with multiple factors such as humid and hot climate, large space, driving interference, and valuable site, the design team of Ruifeng Environmental Protection Refrigeration did not adopt conventional ground or column installation solutions. Instead, they went deep into the site and combined fluid mechanics and air heat exchange principles to develop the following innovative solutions:

1. Space three-dimensional utilization, releasing ground production capacity

Considering the high floor height and sufficient top clearance of the workshop, we innovatively installed the evaporative air cooler (industrial environmental air conditioner) tightly suspended under the roof load-bearing steel beam. This not only does not occupy valuable production floor space at all, but also fully utilizes the physical characteristics of rising hot air to cool the high-temperature air from the source.

2. Avoiding driving operations and achieving precise air supply

Traditional air duct installation is clearly not feasible for bridge cranes operating at a height of 17 meters in the workshop. For this purpose, we have selected a high-power centrifugal lower outlet fan model. This model has the characteristics of high wind pressure and long air supply distance, which can overcome high-altitude obstacles and transport fresh cold air that has been cooled and humidified from top to bottom and vertically over long distances to the ground work surface, effectively forming a "cold air lake" and ensuring the comfort of workers' activity areas.

3. Scientific layout, full coverage without blind spots

After precise calculation of cooling load, we evenly distributed over 100 air coolers under the load-bearing beams on the workshop roof, forming a three-dimensional air supply matrix. At the same time, for corners where a few devices are severely obstructed and airflow is difficult to cover, we have added mobile air coolers. These flexible and maneuverable devices truly achieve the principle of 'people on the machine, people walking and machines moving', which not only ensures local cooling needs but also avoids energy waste.

【 Effect Extension: Trust from Workshop to Exhibition Hall 】

After the implementation of this plan, the workshop environment has significantly improved: air circulation has accelerated, temperature has significantly decreased, humidity is suitable, and dust has been effectively suppressed. Workers have reported a significant improvement in their perceived comfort, leading to an increase in production efficiency; Precision production equipment operates more stably, ensuring the precision of plastic product shaping and resulting in a visible improvement in product yield.

The smooth implementation of the workshop project not only solved the urgent needs of the customers, but also established full trust in the professional capabilities of the Ruifeng team by the factory. Therefore, the factory voluntarily proposed to entrust us with the cooling project of the product exhibition hall located on the first floor of the administrative building.

The exhibition hall is a reinforced concrete structure with good airtightness and higher requirements for comfort and aesthetics. We have customized several high-power dual outlet axial flow industrial air conditioners for it. This type of air conditioner is based on the principle of forced convection heat transfer by axial flow fans, and has the characteristics of large air volume, sufficient cooling capacity, soft air outlet, and low noise. It is also equipped with an intelligent temperature control system that can automatically adjust the operation according to the indoor temperature, creating a comfortable and quiet negotiation environment for visitors.

Project Inspiration: Ruifeng's Multi scenario Solution Capability

Although Ruifeng Environmental Protection Refrigeration is serving a plastic and hardware products factory, the problems it solves, such as "tall space", "high temperature heat source", and "driving interference", are highly representative in many industrial scenarios such as mechanical manufacturing, automotive parts, and new material production. This project fully demonstrates that the Ruifeng team possesses:

1. Comprehensive analysis ability for different building structures (color steel shed, concrete frame);

2. Accurate selection capability for different equipment requirements (evaporative air coolers, centrifugal fans, axial flow air conditioners);

3. Innovative construction capability in the face of complex spatial constraints such as high-altitude driving and ground equipment.

Choosing Ruifeng is not only about choosing a set of ventilation and cooling equipment, but also about choosing a comprehensive optimization plan for the factory environment that can be tailored for you and truly achieve practical results.
