制冷系统组件动态特性的数模分析

Research of components dynamic characteristics of refrigeration system

从制冷系统组成出发,通过建立制冷系统各组件数学模型所研究对象参数流程图,以动态、参量化和参量定量相关的观点,根据工作实际提出建模假定的工况条件,建立对象的物理模型,进而对制冷系统压缩机、冷凝器、过冷器、膨胀阀和量热器等主要组件建立各自的数学模型,实现对组件进行数学的定量和定性的分析与描述.

Allowing for the composition of the refrigeration system, a mathematical model of the components of the refrigeration system is built herein in this paper. The working condition of the mathematical model is sup- posed according to the practical work, and related physical engineering model of those components is built. Fur- thermore, the mathematical models of the compressor, condenser, super cooler, expansion valve and heat indica- tor of the refrigeration system are built so that the refrigeration system can be mathematically analyzed and de- scribed in both quantitative and qualitative analysis.
