The project is located in Nanhai District, Foshan City, in the hinterland of the the Pearl River Delta, and belongs to the subtropical marine monsoon climate. It is warm and humid all year round, with long summer, high temperature and rain, and short and mild winter. Foshan, as an important manufacturing base in China, has a strong industrial foundation, especially in the fields of home building materials, textiles and clothing, and smart homes. As an important part of the home industry chain, curtain production has certain requirements for the temperature, humidity, air circulation, and cleanliness of the production environment. A good workshop environment not only helps to improve the comfort of employees, but also ensures the processing quality of fabrics and the stable operation of equipment.

The renovated workshop is a sewing workshop for an intelligent curtain production enterprise, with a building area of 3000 square meters and a height of 10 meters. It is a typical large flat color steel frame structure. The workshop adopts a combination of brick walls and insulated color steel tile roofs, equipped with large glass windows for good lighting and strong overall sealing. Due to the particularity of production technology, the volume of sewn products is relatively large, and the layout of workstations is relatively loose, unlike clothing or footwear workshops that are densely packed. At the same time, there are no pipeline equipment in spaces over 4 meters, and the clearance conditions are superior, providing ideal conditions for the airflow layout of designated positions.

Based on the actual situation of the workshop, the Ruifeng Environmental Protection Refrigeration Design Team has comprehensively considered multiple factors such as the high temperature and high humidity climate characteristics of Foshan area, workshop building structure, spatial height, workstation layout, and production process requirements, and tailored an efficient and energy-saving ventilation and cooling plan: using a combination system of high air volume centrifugal air coolers and long air ducts for uniform air supply.

Centrifugal air coolers have strong air supply capabilities, which can cool outdoor fresh air and transport it to various workstations in the workshop through long air ducts over long distances. The equipment is installed on the outside of the building wall, effectively saving indoor usable area and avoiding interference with the production layout. The long air duct is hung in the upper space of about 4 meters, and the airflow organization is scientific and reasonable to ensure that the cold air evenly covers the entire work area. The positive pressure environment formed by high air volume can continuously discharge the hot and humid air generated by indoor personnel and equipment outdoors, significantly improving air quality.

From a physical principle perspective, centrifugal air coolers use forced convection heat transfer to cool outdoor air before sending it indoors, creating a continuous supply of fresh air; Positive pressure exhaust effectively suppresses the infiltration of external hot air and maintains stable indoor temperature. After the system was put into operation, the temperature in the workshop significantly decreased, the air circulation was enhanced, the comfort level of employees was greatly improved, and the work efficiency also increased accordingly. Meanwhile, a suitable temperature and humidity environment can help reduce deformation or static electricity problems caused by high temperature and humidity in fabrics, further improving product quality.

The smooth implementation of the ventilation and cooling project in the curtain factory not only demonstrates Ruifeng Environmental Protection's professional ability in selecting and integrating large spaces and special equipment, but also further expands our application experience in similar scenarios. Whether it's furniture manufacturing, textile and clothing, or large-span buildings such as warehousing and logistics, we can provide customized ventilation and cooling solutions according to actual needs, helping enterprises create a more comfortable and efficient production environment.
