By modifying the frequency of the compressor and the opening of the electronic expansion valve, we can precisely control room temperature and superheat temperature. The multi-variable control system is simplified to two individual single variable control systems, while the interaction is treated as the disturbance process of the control system. A prototype of variable-frequency air conditioner system was built and tested. The experiment results show that the room temperature error is less than 0.1℃ and the superheat temperature error is less than 1℃. The performance of the designed variable-frequency air conditioner system is shown satisfactory. |
