【Abstract】 Room air- conditioner refrigerating system is a complex multi- input multi- output system. It is a premise to study its main parameters’ influence on the systematic steady performance for the optimization design of the air- conditioner. Based on the mathematical model used for air- conditioner simulation and an overall consideration on the main components’ internal coupling relationship,an air- conditioner steady performance model library is built by using Modelica. Then based on the library we can build an air- conditioner systematic refrigerating system model which can reflect the main variables’ relations with the systematic performance. Finally,the systematic simulation is carried out on the plateform of MWorks and the result is proved to be credible according to theoretical analysis. The systematic model can be used to study the air- conditioner’s parameter optimization,which is significant meaningful to improve the air- conditioner’s overall performance.更多还原
