外文摘要：The steady-state models of the compressor and electronic expansion valve(EEV), as well as the dynamic models of the heat-exchanger and accumulator of a multi-unit inverter air conditioning system are constructed. The system simulation model is established based on these component models and corresponding boundary conditions. The time response characteristics of main operating parameters such as the refrigerant volume and outlet superheat of each evaporator under the step signals of EEV opening are studied. The results show that the built simulation model can simulate the dynamic characteristics of the multi-split air conditioning system effectively; this study provides the theoretical basis and technical support for understanding the cross-coupling behaviors among operating parameters and making the optimum control strategy.
