制冷剂饱和热力性质的通用简化计算模型
A Generalized Simple Model for Saturated Thermodynamic Properties of Refrigerants
摘要
Abstract
Simple and fast evaluation of refrigerant thermodynamic properties is one of the key factors to the robustness and speed of refrigeration system simulation and optimization. The investigation aimed to find a generalized simple model to be accurate enough in a wider range of parameters. A new six-coefficient simple model was proposed for refrigerant saturated thermodynamic properties. The data of some typical refrigerants were used for data regression. In the common refrigerating and air-conditioning operating conditions, the comparison between the present model and the international standard refrigerant database REFPROP 9. 0 shows that the maximum deviations of refrigerant saturated thermodynamic properties fall into +0. 6%. The calculation speed can be therefore improved two orders of magnitude or more.关键词
