Revision Notes
This code is compiled in accordance with the notification requirements of the former State Construction Commission (81) Jianfashe No. 546, and is edited by China Nonferrous Metals Industry Corporation. Specifically, it is revised by Beijing Nonferrous Metallurgy Design and Research Institute in conjunction with 17 domestic design, scientific research and university institutions to form the original "Design Code for Heating, Ventilation and Air Conditioning in Industrial Enterprises" TJ1975 (Trial).
During the revision process, the revision group conducted a relatively extensive and in-depth investigation and research, summarized domestic practical experience, absorbed relevant scientific research results in recent years, consulted a large amount of domestic and foreign information, and learned from the content of similar foreign technologies that conform to my country's actual situation. It has repeatedly solicited opinions from relevant units across the country and Hong Kong, conducted special research and repeated discussions on some important issues, and finally convened a national review meeting to jointly review and finalize the draft with relevant departments.
This specification is divided into eight chapters and thirteen appendices. The main contents include: general principles, indoor and outdoor calculation parameters, heating, ventilation, air conditioning, refrigeration, automatic control, and sound insulation and vibration isolation.
In the process of implementing this specification, 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 Specification Management Group of Beijing Nonferrous Metallurgy Design and Research Institute (No. 12 Fuxing Road, Beijing) for reference in future revisions.
