摘要
为了避免制冷系统蒸发器建模中机理分析方法的复杂性和不精确性,提出基于广义最小二乘法的蒸发器辨识建模方法。该方法避免了机理分析法繁琐的数学推导,具有更强的可行性,且得出的模型更具有现实意义。模型检验和实际工程应用验证了此方法的有效性。
In order to avoid the complexity and imprecision of mechanism analysis in refrigerating evaporator modeling, an evaporator modeling method based on generalized least square is proposed. The solution can avoid the complex mathematic derivation and has stronger feasibility. So the obtained model has more realistic meaning. The checking of model and the actual application of engineering demonstrate the effectiveness of this approach.
