摘要: | 本研究旨在開發一變頻空調系統,透過控制器改變壓縮機頻率與電子式膨脹閥開度,使室內溫度與過熱度得以精準控制。本研究採用的控制系統係將原多變量系統,簡化為兩個獨立的單變量控制,而交互影響的部分視為單變量控制系統的干擾。本研究實地開發一變頻空調系統,並對系統做完整的測試評估。結果顯示,室內溫度誤差值可控制於±0.1˚C內;過熱度誤差值可控制於±1˚C內,顯示所設計的變頻空調系統性能良好。 The main purpose of the present research is to develop a variable-frequency air conditioner system. 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. |
