基于量纲分析的既有建筑供暖空调能耗模型
HVAC energy consumption model of existing buildings based on dimension analysis
摘要：
分析了既有建筑供暖空调能耗的主要影响因素，利用量纲分析理论建立了能反映供暖空调能耗与其相关影响因素之间关系的能耗模型，得出了能耗的数学解析式。以一实际建筑为例，根据模型计算得到的2007年的供暖空调能耗与实际能耗的偏差在4%以内。

Abstract：
Analyses the major influencing factors of HVAC energy consumption of existing buildings, establishes the energy consumption model reflecting the relationship between the energy consumption and related influencing factors based on the dimension analysis theory, and obtains the mathematical analytic formula of the energy consumption. Validated by an actual building as example, the deviation between the calculated value of the energy consumption in 2007 and the actual value is in 4%.
