用于控制的制冷系统稳态建模与仿真

Modeling and Simulation of a Refrigeration System for Control Purpose

为研究各控制参数对制冷系统性能的影响趋势，对制冷系统进行了数学建模和仿真．模型选用时考虑到既要计算速度快，又要有一定精度，因此对换热器采用“分区集总”的建模方法．为验证仿真结果的可靠性，进行了一定的实验验证，结果表明此仿真程序有一定精度。

A simulation program was set up to investigate the effect trend of the controlling parameters on refrigeration system. For the choice of model of the respective components, it was taken into consideration that calculation should be fast and some accurate as well. “Two (three) zone method” was employed for the modeling heat exchanger. Experiment was also done to testify the accuracy of the simulation results and it was acceptable.
