蒸气压缩式制冷装置仿真的基本理论和热点问题

针对蒸气压缩式制冷装置仿真的基本理论进行了总结。将稳态仿真方法归纳为四种 :连续替代 (SS)方法、牛顿 -辛普生 (NR)方法、顺序模块 (SM)方法以及联立方程解 (SES)方法。动态仿真研究在总量上还较少 ,从中难以归纳出普遍适用的方法。模型的数值健壮性、模型的通用性以及大型机组的仿真是目前的热点问题。

Basic Theory and Key Problems on the Simulation of Vapor-compression Refrigeration Plants

An overview was made to the basic theory on the system simulation of vapor-compression refrigeration plants. The steady-state simulation techniques can be reduced to four kinds of methods, which are Successive Substitution (SS) method, Newton-Raphson (NR) method, Sequential Modular (SM) method, and Simultaneous Equation Solving(SES) method. Dynamic models are still lack. It is difficult to reduce a general method. The present key problems of the simulation study are those: the numerical robustness of models, universal property of models, and the simulation of large-scale refrigeration plants.
