For the vapor compression refrigeration cycle systems, there are many assumptions existed in its distributed parameter model of previous work which can loss the simulation accuracy. Such as the refrigerant-side pressure drop is neglected, the accumulator, connecting pipe and compressor lubricant are not considered sometimes and so on. In this paper, a detailed dynamic model of split-type air conditioner was developed based on SIMULINK. This model included multiple sub-models such as evaporator, condenser, compressor, electronic expansion valve, accumulator, and pipe. The evaporator and condenser were modeled by the distributed-parameter method and the refrigerant-side pressure drop was estimated. The accumulator with lubricant and connecting pipe used the single-node lumped parameter model. Then this model was verified by experimental data. The results showed that the system dynamic behavior was accurately captured.
