Summary

For the distributed parameter model for vapor compression cycle systems (VCCs), there are several assumptions compromising 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 system model contains multiple sub-models including the evaporator, the condenser, the compressor, the electronic expansion valve, the accumulator, and the pipe. The evaporator and condenser were modeled using the distributed-parameter method with the estimated refrigerant-side pressure drop. The accumulator with lubricant and connecting pipe adopted the single-node lumped parameter model. Thereafter, the model was verified via experimental data. The results showed that the system dynamic was captured accurately.
