摘要
变频房间空调器由4个关键部件组成,每一部件又包含影响空调制冷性能(如制冷量、能效比等)的多个相关参数。为了分析空调部件及系统主要性能指标和关键参数的关系,以为空调制冷系统的参数设计与性能分析提供依据,建立了基于Modelica的变频空调稳态性能仿真模型库,包括关键部件模型及制冷工质热力性质和热物理性质计算模型等。基于该模型库建立变频空调制冷系统仿真模型,在MWorks平台上对其进行仿真,仿真结果与理论分析相符。
Inverter room air-conditioner is composed of 4key components,each of which has a lot parameters related with refrigeration performance(refrigerating capacity,EER etc).In order to analyze the relationship of components'and systematic main performance indicators'with their key parameters so as to support main parameters'determination and predict the systematic main performance,a steady performance model library of refrigerating system is built.This library is based on Modelica and includes key component models and models which calculate the themodynamic properties and thermophysical properties of the refrigerant.Based on the library,a systematic model of the DC inverter air-conditioner can be built.Then on the plateform of MWorks,the simulation is carried out,the results coincide well with theory values.
