空调器动态性能测量用建筑负荷特征研究
Research on the parameters of building load characteristics of air conditioner dynamic performance measurement
摘要
Abstract
In view of the problem that laboratory measurements cannot fully reflect the real performance of air conditioners,the dynamic performance measurement of air conditioners based on virtual buildings has become a research hotspot.Virtual building features are a key part of the dynamic performance evaluation of air conditioners.This paper firstly analyzes the three methods of obtaining the capability of air conditioners,including enthalpy difference room measurement,on-site operation performance measurement,and laboratory dynamic measurement,and points out that laboratory dynamic measurement based on virtual building is the only way to evaluate the performance of air conditioners.Through simulation and model analysis,the load characteristics of the room under different operating characteristics were determined,and the linear relationship between temperature and load combined with the selection coefficient was proposed to describe the virtual building load.The recommended values of the selection coefficients for the cooling and heating conditions of air conditioners in hot summer and cold winter are 1.33 and 1.50,respectively.关键词
