應用模糊邏輯於VRF多聯式變頻空調系統之室內舒適度控制
Application of Fuzzy Logic on Thermal Comfort Control of Variable Refrigerant Flow Multi-Split Air-Conditioning System
摘要
在科技發達的時代，人類對於生活水平的要求越來越高，不論是辦公場所、百貨商場或一般家庭，皆無法脫離空調的使用，但在能源危機的當下，要如何同時兼顧能源節省與滿足生活需求，已經是首要條件。 本研究參考美國冷凍空調協會ASHRAE Standard 55-2004規範與國際標準ISO7730規範，針對人員的舒適感受開發一套智慧型監控系統，以Visual Basic 6.0程式開發軟體結合PLC可程式控制器，建立出環境監測功能與智慧型控制功能，透過各項感測器測得室內、室外環境狀態，並由智慧型控制系統透過模糊邏輯演算出最佳運轉狀態，以控制VRF多聯式變頻空調系統。 經實驗結果顯示，本研究所開發的系統能有效的將室內舒適度穩定在使用者設定的目標值，且在室內負載發生變化時，系統能快速的使室內舒適度回穩，不僅擁有良好的穩定性，亦能夠有效克服外在的干擾因素。

In the current energy crisis, how to save energy and maintain the indoor thermal comfort is a primary issue. Refer to ASHRAE Standard55 and ISO7730 norms, which suggest that the indoor environment for human is the one with value of thermal comfort index PMV between -0.5~0.5. This study designs an intelligent monitoring system, which can monitor indoor environment in real-time, and control the variable refrigerant flow multi-split air-conditioning system by PLC controller. The experimental results showed that the intelligent monitoring system proposed in this study, which applys a fuzzy logic that can keep PMV to be close to the set value. In the other hand, the power consumption of set PMV at 0.5 is less than set PMV at 0, which means the highest PMV set between the thermal comfort zone can save more energy.
