Located in Wenzhou, a coastal industrial city with mild and humid seasons and hot and rainy summers, a clothing OEM enterprise is facing severe challenges brought by the production environment. As an important part of the four traditional light industries in Wenzhou (clothing, shoes and hats, glasses, lighters), the clothing manufacturing industry has extremely high requirements for the temperature and humidity of the production environment. A stable workshop environment not only ensures the comfort of workers' operations, but also plays a core role in controlling fabric shrinkage, maintaining fabric flatness, and improving product quality, directly affecting the market competitiveness of enterprises.

The building structure of the factory is a multi story reinforced concrete standard factory, with skylights on the walls. However, due to its early construction, the floor height is only about 4 meters. Low and enclosed spaces are prone to heat accumulation in summer. Although equipped with traditional fans, they can only achieve air flow and cannot fundamentally solve the cooling problem. The heat source in the workshop mainly comes from two aspects: one is the human body heat dissipation of employees engaged in intensive operations, and the other is the strong outdoor solar radiation heat in summer. Although industrial sewing machines have limited heat production, the heat load caused by personnel density makes the entire workshop often stuffy and unbearable during peak seasons, which not only affects the condition of employees but also potentially interferes with fabric characteristics and sewing accuracy.

Based on the design concept of adapting to local conditions and systematizing environmental governance, the engineering team of Ruifeng Environmental Protection Refrigeration conducted on-site investigations and comprehensively analyzed the following key factors:

1. Geographical climate: Wenzhou experiences high temperatures and humidity in summer, requiring a balance between cooling and dehumidification;

2. Limitations of the factory building: The height of the floors and the enclosed space require soft air supply and even coverage of the equipment;

3. Industry characteristics: Clothing production requires moisture and direct blowing prevention to avoid affecting fabrics and fine operations;

4. Personnel density: The heat load is concentrated, requiring sufficient and adjustable cooling capacity.

Based on the above analysis, we have abandoned the conventional evaporative air cooler solution - this device is prone to increasing air humidity in warm and humid climates, which may cause fabric moisture and deformation, and cannot accurately control temperature. In the end, we customized multiple high-power vertical dual outlet axial flow industrial air conditioning systems for it along the wall:

1. Dual outlet high-power design: ensuring sufficient cooling capacity, wide temperature and humidity adjustment range, and flexible control according to real-time workshop load;

2. Axial flow wind technology: The air outlet is smooth and gentle, avoiding discomfort for employees or fabric movement caused by strong winds that affect production. At the same time, it can cooperate with the original fan system to achieve uniform airflow distribution and eliminate temperature blind spots.

3. Transformation Effect: Overall Improvement from Production Environment to Enterprise Efficiency

After the renovation, the overall temperature and humidity of the workshop were stably controlled, and the staff bid farewell to the hot and sticky working environment of the past. The physical and mental comfort was significantly improved, attention was more focused, the defect rate decreased, and production efficiency was effectively improved. At the same time, a stable temperature and humidity environment reduces the stretching deformation of the fabric caused by environmental fluctuations, providing a guarantee for sewing accuracy and product consistency, and strengthening product quality from the source.

In addition, this project fully demonstrates Ruifeng's professional ability to achieve efficient environmental transformation without changing the original factory structure and making full use of existing ventilation facilities. This system solution is not only applicable to the clothing manufacturing industry, but can also be widely used in environmentally sensitive and personnel intensive industrial scenarios such as electronic assembly, food packaging, and precision machining, demonstrating our adaptability and technological versatility to meet the needs of different industries.

Ruifeng always believes that ventilation and cooling is not only about equipment installation, but also a systematic solution based on on-site conditions and industry characteristics. We are guided by long-term cost-effectiveness and choose truly sustainable workshop environment solutions for our customers, helping enterprises win the market and the future in a comfortable and stable production environment.
