Preparation Instructions
This standard is edited by China Nonferrous Metals Industry Corporation in accordance with the requirements of the former State Construction Commission (82) Construction No. 20 "Notice on the Preparation of Professional Terms and Terminology Standards for Engineering Construction", and is specifically prepared by Beijing Nonferrous Metallurgy Design and Research Institute in conjunction with relevant domestic scientific research and design units.
During the preparation process, the preparation team conducted extensive and in-depth investigations and studies, collected and consulted a large amount of information at home and abroad, drew on useful parts of similar foreign standards, repeatedly solicited opinions from relevant units across the country and Hong Kong, conducted special research and repeated discussions on some difficult issues, conducted correspondence review across the country, and finally held a review meeting to review and finalize the draft together with relevant departments. This standard is divided into 9 chapters and 35 sections, including 1001 commonly used terms. Its main contents include: general principles, indoor and outdoor calculation parameters, heating, ventilation, air conditioning, refrigeration, automatic control, noise reduction and vibration isolation, detection instruments and others. In view of the fact that this standard is newly compiled, in the process of implementation, please pay attention to summarizing experience and accumulating information. If you find that there is a need for modification and supplementation, please send your opinions and relevant information to the HVAC Standard Management Group of Beijing Nonferrous Metallurgical Design and Research Institute (No. 12 Fuxing Road, Beijing, Postal Code 100038) for reference in future revisions.
