  Thursday, June 23, 2022: The HVAC technology exchange meeting between CCDI International Design Institute and Uetersen Western Subsidiary was held in the conference room on the 7th floor of Dayuan International Center, Chengdu High-tech Zone. CCDI International Design Consultants Co., Ltd. (hereinafter referred to as CCDI): a large-scale engineering design consulting group that closely combines high-quality design services with product thinking. Since its establishment in 1994, CCDI has explored a path of transformation with the characteristics of China's engineering design industry, achieved international business expansion, and has been ranked among ENR's top 100 global engineering design companies for many years. In this meeting, Uetersen Western Subsidiary and CCDI International Design Institute conducted exchanges and discussions on HVAC and thermal insulation technology.


  In this HVAC exchange meeting, the technology of glass fiber duct, formaldehyde-free glass wool and the application of smoke prevention and exhaust were discussed. Rong Zezhong and Xue Jing, technicians from western Chengdu, gave lectures at the conference. CCDI has set up a wealth of product lines in the fields of sports, commerce, office, medical care, human settlements, cultural tourism, municipal administration, transportation, planning, etc. These product lines require a large amount of glass wool in the direction of smoke and fire prevention ducts Wait for fireproof package. Zuo Gong, the chief engineer of HVAC Design Department of CCDI International Design Institute, who participated in this communication, is the main person in charge of CCDI. At this HVAC technology exchange meeting, he had an in-depth understanding and expressed the standards and requirements of the use direction in terms of fire resistance limit, smoke prevention and exhaust system, application of formaldehyde-free glass wool, and application direction of composite glass fiber air duct.


  Rong Zezhong, the lecturer of Uetersen Technology, introduced the raw materials of formaldehyde-free glass for CCDI: "Glass wool is a widely used thermal insulation material, because it is made of quartz sand and dolomite. It belongs to A1 grade non-combustible material, and is often used as a fireproof package for thermal insulation in all directions of the building." In the direction of the anti-smoke and exhaust air duct package, he introduced the formaldehyde-free construction method and the extension of use in other fields to Zuo Gong, and focused on explaining CCDI The technical construction of the product in the planning field.


  Zuo Gong, the main person in charge of CCDI HVAC Design Department, also raised a question about the fire resistance limit time of formaldehyde-free formaldehyde. Rong Zezhong, the technical director of Uetersen, answered the above questions: "Uetersen formaldehyde-free glass wool has super-long and slender glass wool fibers, and the fiber diameter is about 4-5 microns, which is larger than the glass wool fibers on the market. It is mainly composed of silica, which is high temperature resistant and fireproof. In terms of production technology, the technical difficulty of melting raw materials and fiber drawing in materials with high silica content is often higher, but the fire resistance limit in a fire is longer. It lasts for a long time, and fully meets the fire resistance standards of smoke and exhaust fire pipes.”


  Uetersen is a brand specializing in R&D and production of thermal insulation materials. Thermal insulation products have rich project experience in the fields of building HVAC, smoke prevention and exhaust. In addition to product research and development, Uetersen also has a complete technical solution service system. Relying on the precipitation and technical concepts of the thermal insulation industry for many years, it has been continuously innovating and developing environmentally friendly and energy-saving thermal insulation materials for more than ten years. In the future, we will continue to focus on environmental protection and energy conservation, adhere to the goal of scientifically developing green life, and provide high-quality products and service solutions for more projects.
