The second working meeting of "Technical Standards for Ductless Fresh Air System" was successfully held
On September 23, 2021, the second working conference of "Technical Standards for Ductless Fresh Air System" was successfully held at the China Academy of Building Research. Dai Zizhu, a researcher at the Chinese Center for Disease Control and Prevention, Liu Chunqing, a researcher at the China National Institute of Standardization, Deng Gaofeng, director of the Low-Carbon Building Research Center of China Academy of Building Research Co., Ltd./Senior Engineer Guan Yunlong, Architectural Design Institute of China Academy of Building Research Engineer Chen Lei of the Institute, Haoting (Tangshan) Environmental Technology Co., Ltd., Baoji New Hiking Materials Supply Co., Ltd, representatives of Yijia Environmental Technology (Guangdong) Co., Ltd., and representatives of participating units attended the meeting.
 

 
The meeting first gave a brief introduction to the relevant situation of the first working meeting of this standard, the results of the perfect communication with the participating units on the standard content after the meeting, and the content that needs to be discussed in this meeting. The representative of the editor-in-chief of the standard, Dr. Yunlong Guan, gave a detailed introduction to the framework of the first draft of the standard, the main articles of thought, key content, etc., and the representatives of the participating units gave full play to their respective expertise, put forward new opinions and suggestions on the preparation of the standard, and jointly discussed the related terminology of the ductless fresh air system Discussion and analysis of the definition, design specifications, and construction acceptance methods have made the standard provisions more complete.
 
At present, there are many publicity styles about ductless fresh air system, but due to the incompleteness of existing relevant technical standards and inconsistent concepts, it is difficult to distinguish between authenticity and falsehood, and it is difficult to choose. Moreover, for ductless fresh air system design criteria, installation procedures, and acceptance standards There are no clear regulations, and there is a lack of reference documents for companies and markets. The "Technical Standards for Ductless Fresh Air System" stipulates terms related to ductless fresh air systems, and regulates system design, equipment and materials, construction and installation, inspection, commissioning, acceptance and operation and maintenance. This standard applies to the installation of ductless fresh air systems in new and existing civil buildings. The compilation of this standard will put forward more specific requirements for the current ductless fresh air system on the basis of the existing heating and ventilation system standards, which will be more referential and instructive for related markets and enterprises.
