Wenzhou, a city located on the coast of the East China Sea, has a warm and humid climate with hot and rainy summers, belonging to a typical subtropical monsoon climate. It is on this land that Longwan District, with its unique geographical location and profound industrial accumulation, has become one of the largest synthetic leather production bases in Asia. As one of the traditional advantageous industries in Wenzhou, the synthetic leather industry started early, has a solid foundation, and a complete chain. Its products are exported to many countries and regions such as Europe, America, and Southeast Asia, making important contributions to local economic development and social employment.

However, the production process of synthetic leather has high requirements for environmental conditions such as temperature, humidity, and ventilation. High temperature and stuffiness not only affect workers' work efficiency and physical health, but may also have potential impacts on product quality. Therefore, creating a comfortable, safe, and stable production and operation environment has become an important part of enhancing the competitiveness of enterprises.

This enterprise is one of the many synthetic leather production enterprises that have developed based on the industrial cluster effect. Most areas of its production workshop have been equipped with fixed ventilation and cooling equipment such as air conditioning, fans, and exhaust fans, which basically meet the temperature control needs of conventional production areas. However, in some special areas, such as the front desk of the lobby, logistics loading and unloading areas, and relatively open spaces, as well as ventilation blind spots in some production areas, there are still problems of high temperature and poor air circulation, which urgently need to be improved.

Based on the characteristics of these areas, the design team of Ruifeng Environmental Protection Refrigeration has comprehensively considered multiple factors, including the humid and hot climate conditions in Wenzhou, the difficulty of closing open areas, the flexibility and economy of equipment, and the impact on normal production order. Finally, a layout plan for mobile centrifugal air coolers has been proposed. The advantages of this plan are reflected in the following aspects:

1. Flexible response to personnel flow: Due to the uncertainty of personnel activity areas, fixed equipment is difficult to fully cover, while mobile air coolers can adjust their position at any time according to actual needs, truly achieving "changing with people".

2. Adapt to open space environment: Open spaces such as logistics areas cannot be effectively enclosed, air conditioning effectiveness is greatly reduced, energy consumption is high, and temperature differences are reduced. And the air cooler relies on the physical principle of "water evaporation cooling", utilizing the heat absorption effect of water vaporization to naturally lower the air temperature, which is both energy-saving and environmentally friendly, especially suitable for use in semi open or open spaces.

3. Strong air volume, improving body feel: Centrifugal air coolers have the characteristics of high air volume and long-distance air supply, which can quickly cover local areas, significantly improve stuffiness and heat sensation, and enhance employees' work comfort and efficiency.

4. Plug and play, without affecting production: The equipment does not require installation of fixed pipelines or modification of the original structure, plug and play, flexible deployment, and does not interfere with daily production rhythm.

5. Low cost investment, high cost-effectiveness: Compared to fixed equipment such as central air conditioning, mobile air coolers have lower initial investment and more economical operating costs. Enterprises do not need to bear excessive financial pressure and can achieve significant improvements in local environments.

After the project was put into use, the feedback from on-site employees was positive, generally believing that the working environment was significantly cool and comfortable, and production efficiency also improved accordingly. The company leader highly praised Ruifeng Environmental Protection Refrigeration's professional solutions and services, believing that it was a successful practice of "small investment, big improvement".

Although this is a mobile fan deployment project for synthetic leather enterprises, its solution has strong replicability and promotional value. Similar application scenarios also include logistics warehouses, large exhibition venues, temporary activity venues, sports training centers, and other areas that require flexible ventilation and cooling. Ruifeng Environmental Protection Refrigeration has the ability to comprehensively select and design solutions for special spaces and usage scenarios, and can provide customers with efficient, economical, and reliable customized solutions.
