The Scientific and Technological Achievement Evaluation Meeting of the Project Key Technologies and Equipment of Building Low-Carbon Heating and Air Conditioning in the Yangtze River Basin

On April 25, 2022, the Science, Technology and Industrialization Development Center of the Ministry of Housing and Urban Rural Development organized and held the scientific and technological achievement evaluation meeting of the project Key Technologies and Equipment of Building Low-Carbon Heating and Air Conditioning in the Yangtze River Basin participated by Chongqing University. The meeting was held both online and offline. Academician Zhuang Weimin of the Chinese Academy of Engineering served as the director of the evaluation expert group, and professor Wu Desheng of Beijing Architectural Design and Research Institute Co., Ltd. and professor Li Deying of Beijing University of Architecture served as the deputy directors. Lin Wenzhuo, director of the Science, Technology and Industrialization Development Center of the Ministry of Housing and Urban Rural Development, presided over the meeting.

Professor Li Baizhan of Chongqing University made a detailed report on the innovation achievements of the project on behalf of the project team. Based on the challenges of ‘carbon peaking and carbon neutralization’ of buildings in the Yangtze River Basin and the urgent needs of thermal environment improvement, the project has made innovative breakthroughs in the theory and application technology system of dynamic building thermal environment low-carbon construction system, high-efficiency air source heat pump technology and equipment suitable for cold winter and hot and humid summer climate, building heating air conditioning low-carbon comfortable terminal and system intelligent operation and maintenance. As a result, the production line has been established, industrialized application has been realized, and integrated demonstration has been carried out in more than 40 projects in the Yangtze River Basin. The effect of energy conservation and carbon reduction is remarkable, which provides an important support for helping the national dual carbon goal.

The experts of the evaluation committee listened to the report on the achievements of the project. After careful inquiry and evaluation, they agreed that the project''s dynamic building thermal environment low-carbon construction system theory, air source heat pump high-efficiency frost detection/Defrosting/frost free technology, compressor pressure ratio adaptation and variable volume regulation technology, system online real-time performance measurement and other technologies are highly innovative, reaching the international leading level and have the value of popularization and application.
