subject: Small Diameter Copper Tube Brass Trigger Mandatory Expander Technology Revolution - Heat Pump, [print this page] April 8, 2010 morning at the Beijing International Exhibition Centre Hall at the "2010 China Refrigeration Exhibition" during the International Copper Association (China), Zhongshan City, Ogilvy & Mather Sen Industry Co., Ltd. jointly organized the "small diameter brass Compulsory Expanding Technology Seminar "held successfully, as this exhibition important technical exchange activities by the industry's attention and expectations.
International Copper Association (China), Household appliances and high-Yi Feng, director of technology innovation
Beginning of the meeting, the International Copper Association (China), Household appliances and technology innovation director Mr. Gao Yifeng guests to the participants a warm welcome, and the International Copper Association in the field of technological innovation and HVAC Industry support for the work done to do a brief introduction, and said the International Copper Association and Copper will continue to support projects related to technological innovation, to explore the potential of copper to enhance the use value of copper. Zhongshan Long Xiaoming, general manager of Ogilvy & Mather Sen on "small diameter brass forced expander technology" to do a thorough introduction, followed by the International Copper Association, project manager for small diameter copper tube Song Ji force expander machine to do ROI Analysis a full description.
Zhongshan Long Xiaoming, general manager of O & M Mori
Small diameter copper tube expander using traditional Expanding Technology will encounter the problem of low pass rate, compulsory expander heat exchanger by clamping both ends of a good way to solve this difficulty, Expanding the passing rate remained at 99.6%. And force the expander machine in conservation of raw materials, high yield, process guarantee of the outdoor unit of small diameter, high transmission efficiency has obvious advantages compared with traditional tube expander, can be recovered within 9 months of extra investment costs .
Project director the International Copper Association, Ji Song
International Copper Association, is the world's most important to promote the rational and efficient use of copper in the non-profit international organization. Small diameter high efficiency air conditioners, room air-conditioning project is committed to the development of small and efficient, room air conditioning heat exchanger through the realization of the small diameter of copper and brass to keep the excellent quality heat transfer, while significantly reducing air conditioning costs, to achieve the interests of consumers win-win situation with the development of the industry. Project co-Xi'an Jiaotong University and Shanghai Jiaotong University and other research institutes, copper processing and the well-known member of the room air-conditioning company set up R & D project team, co-efficient air conditioners for small diameter research and development, the room air conditioning heat exchanger copper tube diameter from 7mm to change to 5mm, 4mm and more detailed models, and conduct system optimization, heat exchanger, the cost of saving can theoretically about 30%, 40% and more. Meanwhile, the small diameter room air conditioning systems can be reduced by 20% to 30% of refrigerant charge amount for the state Environmental protection , Emission reduction offers more career choices.
