Multi-split type air-conditioning systems for buildings that have multiple indoor units require the system performance analysis under various operating conditions for optimization of their design and operation. In this paper, a cycle simulation model for multi-split type air-conditioning systems is developed because the system performance analysis by experimental approaches takes a lot of time and energy. The simulation model is based on a module partitioning approach so that the model can be easily extended to various kinds of system configurations and refrigerants. Moreover, the cycle performance of a multi-split type air-conditioning system that has two indoor units is analyzed by using this model. The result reveals the cycle performance under a typical operating condition where the inlet air temperatures to the two indoor units are different.
