With the rapid development of China's urbanization, green has become the subject of modern architecture and equipment systems development. High-performance of green air conditioning system design, operation and management, and system evaluation is one of the key technologies of green buildings. Based on the analysis of domestic and international green building evaluation system, and the study of green air conditioning system diagnostic indicator system suitable for China, including the theory and principles of diagnosis, diagnostic criteria and diagnostic parameters and result indicates, established a multi-level, multi-target, multivariate diagnostic indicator systems suitable for China. Expect to provide technical support for green technology development and application air-conditioning equipment systems. (C) 2015 The Authors. Published by Elsevier Ltd.
