重庆市办公建筑空调工程设计能效比统计分析
Statistical analysis of design energy efficiency ratio of central air conditioning system in office buildings in Chongqing
摘要：
提出了空调工程及其子系统设计能效比的计算方法，在对重庆市办公类公共建筑36个空调工程的设计情况进行调查统计的基础上，计算了冬、夏工况下空调工程的冷热源系统、水系统、风系统的设计能效比。分析了空调工程冷热源系统、水系统、风系统的设计能效比出现最大值、最小值的原因，探讨了设计能效比的平均值、偏差情况及提高设计能效比的途径。
Abstract：
Presents the calculation method of design energy efficiency ratio (DEER) for air conditioning system and its subsystems. Based on the investigation of thirty-six air conditioned office and similar duty buildings in Chongqing, calculates the values of DEERs for the air conditioning system in summer and winter, including the DEERs for the whole project, the cold and heat source system, the water system and the air system. Analyses the reasons for the maximum and minimum values existed in the four DEERs. Discusses mean value and deviation of the DEERs and the approach to increase the DEERs.
