摘要
建立了VRV空调系统各部件数学模型 ,根据系统各部件的特点 ,用分相集中参数法建立了蒸发器和冷凝器数学模型 ,用集中参数法建立了压缩机和电子膨胀阀数学模型 ,并编制了仿真程序。在VRV空调系统整机性能实验台上对建立的数学模型进行了验证 ,证明了所建立的数学模型正确。
Mathematical models of different parts of the VRV air\|conditioning system are established. For the evaporator and condenser, the models are established by dynamic and concentrating method in each zone. For compressor and electronic expansion valve, the models are established by steady and concentrating method in the whole unit. Based on the mathematical models, the emulator is programmed. Compared with the experiment results, there are only small differences between each other. It is proved that the established emulator is correct.
