人員偵測蒸氣壓縮空調智慧型控制系統研發

本研究目的為研發一套偵測人員預先調控的空調系統，利用人員視訊偵測技術並模糊控制理論做為控制手法，針對在一空調供區域內，利用區域內人員熱負荷數量不同和設定溫度與室內溫度差的變化，控制空調系統的壓縮機頻率以及送風機風速，設計一套節能且兼顧舒適的空調系統。本實驗對於不同控制策略對系統影響進行分析。實驗模擬環境為夏日外氣溫度為35°C使用空調情況進行研究探討。研究結果顯示，在室內兩人、四人以及六人情況下相較於傳統控制分別節能11%、14%以及23%。室內穩態後溫度傳統On-Off控制穩態誤差為±1°C，而智慧型控制空調有較佳的穩態誤差約±0.3°C。利用人員偵測之系統，在人員熱負荷變動較大的情況下能有較好的穩態溫度，同時當人員熱負荷離開空調區域時能夠及時降載，避免室內熱負荷變少的情況下不必要的浪費，比一般變頻節能約7%。由以上結果證明本研究設計之智慧型控制手法利用人員偵測技術應用於蒸氣壓縮循環系統上有明顯的降低耗電量，並且能有較佳舒適溫度。

This studies aim to develop a set of pre-detection officers controlled air conditioning system. By using human detection technology with applying a fuzzy algorithm for air conditioning supply region. Saving energy and maintaining the thermal comfort level are the two main goals to deal in this air conditioning intelligent control system. The variation of number of indoor people and its heat load changes tested in this study’s experiment. The results shown that the fuzzy controller can save energy, compared with traditional ON/OFF methods saving a total of 11%, 14% and 23% respectively on each experiment with indoor temperature setting at 27°C; compared with variable frequencies of the compressor gave as as result a better steady-state temperature, in the care that people leaves the area the air conditioning can reduce the frequency, immediately and avoid unnecessary waste, saving 7% of energy.
