Establishment and Analysis of Fault Model for the Central Air-Conditioning System

This paper analyzes the dynamic fault information (temperature, pressure, flow, noise, vibration etc.) in the process of operation of the air-conditioning system and establishes the simplified qualitative physical model which takes the surface air cooler as an example, and then writes out the mathematical model according to the simplified model. Finally, the paper gets some conclusions or conjecture suitable for the material object according to the research of the mathematical model.
