本文论述了建立随机气象模型作为空调系统热过程分析的外界条件的理由,并给出一种新的随机气象模型——多元时间序列模型。文章较仔细地讨论了建立这种模型的方法和用这种模型模拟气象参数的理论根据,并述及为了使模拟结果不失真模型所要具备的条件。最后,简单说明这个气象模型的一些实际应用。 This paper discusses the reason for establishing stochastic weather model as the external condition of thermal process analysis of air conditioning system, and presents a new stochastic weather model - multiple time series model. The article discusses in more detail the method of establishing such a model and the theoretical basis of using this model to simulate meteorological parameters, as well as the conditions necessary for the simulation results not to be distorted. Finally, a brief description of some practical applications of this meteorological model.
