Project Background and Challenges

Wenzhou, a city located on the coast of the East China Sea, belongs to a typical subtropical humid monsoon climate. The summer is hot and humid, and the terrain, known as the "seven mountains, two waters, and one field", often obstructs air circulation. The feeling of "sauna sky" is particularly obvious. As an important production base of China's luggage industry, Wenzhou has a profound history of leather products. From early handmade workshops to modern assembly line production, Wenzhou luggage carries the light industry dream of "bringing China with the world". Its products not only pursue durability, but also strive for excellence in details and craftsmanship.

The enterprise served by this project is a modern factory specializing in the production of travel suitcases. The core area that requires ventilation and cooling renovation is its large assembly workshop.

This workshop is a typical large-span color steel tile structure factory building, with extremely transparent space, a large area, and high ceilings as its prominent features. There are only a few highlight machines, carving and milling machines, and cutting equipment in the workshop, while the vast majority of the remaining areas are densely populated with manual assembly workbenches. Due to the precise assembly process of luggage and the absence of tall equipment to cover it, the workshop has a high degree of openness. If traditional central air conditioning or large industrial air conditioning is used for overall cooling, not only will the initial equipment investment be huge, but the later operating energy consumption will also be astonishing. For enterprises, it is both wasteful and environmentally unfriendly, which is an extremely uneconomical account.

Ruifeng Plan: Flexible and maneuverable "point-to-point" cooling strategy

In response to this pain point, the design team of Ruifeng Environmental Protection Refrigeration went deep into the site, combined with the humid and hot geographical climate of Wenzhou, the personnel intensive characteristics of the luggage assembly industry, and the customer's demand for strict cost control of input-output. They abandoned the traditional "large and comprehensive" fixed cooling idea and innovatively proposed a "local space, flexible air supply" solution with mobile centrifugal air coolers and mobile industrial grade large fans as the core.

This design is mainly based on the following considerations:

1. Dealing with the uncertainty of layout: The workstations in the assembly workshop are not fixed, and the assembly line layout is often adjusted due to order requirements. The mobile models we have chosen come with swivel wheels, which can be "moved" at any time according to changes in personnel activity areas, truly achieving "wherever people go, the wind follows them".

2. Matching industry process characteristics: Luggage assembly does not require precise temperature control, and employees' most urgent needs are to "eliminate stuffiness and wind blowing". Compared to expensive enclosed air conditioning systems, the combination of evaporative air coolers (environmentally friendly air conditioners) and industrial grade large fans achieves a "natural wind" sensation at an extremely low cost, perfectly meeting industry needs.

3. The perfect combination of physical efficiency enhancement:

1) The mobile centrifugal air cooler applies the physical principle of "water evaporation absorbs heat" (using the temperature difference between dry and wet spheres), which can cool the hot air outside the workshop through a water curtain and send it into the workshop, bringing fresh and cool humid air and effectively reducing the temperature in the area.

2) The mobile industrial grade large fan (with a diameter of over 1 meter and using permanent magnet stepless speed regulation technology) utilizes the aerodynamic principle of "large diameter, low speed" to generate soft, three-dimensional natural wind energy that covers a large area of the work area, blowing on the surface of the human body to accelerate sweat evaporation and bring a comfortable effect of 3-5 ℃ temperature reduction.

3) The combination of the two is used, with the air cooler responsible for providing a "fresh air source" and the large fan responsible for "stirring and dispersing" the cold air, quickly dispelling the stuffiness and heat in the workbench area, ensuring the physical and mental health of employees, and enhancing work enthusiasm.

Usage effect and customer evaluation

After the implementation of the project, the assembly workshop working environment of the luggage factory has been significantly improved:

1. Plug and play, zero installation cost: After the equipment arrives, there is no need to lay complex air duct circuits. It can be plugged in and used during work, and can be directly removed and stacked after work or idle without affecting other operations in the workshop.

2. Saving money is making money: the equipment operates with extremely low energy consumption, only 1/8 or even lower than traditional air conditioners. The person in charge of the client said, "Ruifeng's plan allows us to accomplish big things with small money. Not only can we keep our employees, but the efficiency is also high. The return on investment for this project is very high

3. Owner's positive review: Employee feedback: "The wind blowing on me is very comfortable, not the bone chilling cold, like natural wind, can stay in place

Expansion and extension: not limited to luggage factories

The success of this luggage factory project is not only a victory for a single case, but also confirms Ruifeng Environmental Protection's ability to design solutions for special spaces and usage scenarios. This type of mobile fan combination scheme is also applicable to:

1. Large mechanical processing workshop (local high temperature point cooling)

2. Temporary exhibitions or warehousing logistics centers (unable to install fixed equipment)

3. Temporary activity area for sports venues or large shopping malls (flexible layout required)

We are well aware that every ventilation and cooling project is not just a simple stacking of equipment. Ruifeng Environmental Protection Refrigeration is committed to tailoring the most efficient, economical, and comfortable "natural wind" environment for various special industrial and commercial spaces through precise comprehensive selection, scientific scheme design, and lean control of customer costs. Choosing Ruifeng means choosing a refreshing and worry free option.
