應用模糊控制於空調系統舒適度節能之分析
Application of Fuzzy Control System on Energy-Saving Analysis of Thermal Comfort of HVAC
摘要
生活在高科技環境的今日，空調更是無法或缺的一項產品，無論是在高科技廠房、商辦大樓、自家住宅…等，都依賴空調來達到特定之目標。以目前地球的資源及環境來評估，除了能享受空調帶來的便利之外，更要講求使用者的舒適感及經濟效益，所以要如何兼顧舒適度及節能效益是必須的。 以往冰水主機出水溫為一固定值，常常會造成空間過冷造成不舒適且耗能，所以在本研究中探討在各冰水出水溫狀況下，並且維持室內舒適度的狀態，來分析研究區域泵、空調箱送風機及冰水主機耗電量大小，找出一個耗電量組合最小的冰水出水溫設定。因此，本研究建立一套控制系統，藉由模糊理論來控制空調系統中冰水主機壓縮機、區域泵、空調箱送風機的頻率，以達成室內舒適度條件及固定冰水出水溫。由實驗結果得知冰水出水溫12℃時，可有效維持室內舒適度於0.5，並且可以有效的節省能源。

In the modern high-tech world, air conditioner has become one irreplaceable product which is equipped with high-tech factories, business buildings and dwelling houses to achieve the specific objective. Evaluating from the perspective of the current earth resources and environments, apart from the convenience coming from the air conditioner, the comfort and economic benefits of the users are also demanded. As a result, it has to balance the comfort and energy-saving benefits. Conventionally, the outlet temperature of water chiller unit is a constant value, which tends to cause the discomfort and power consumption due to extremely low temperature. Therefore, this paper explores and analyzes the power consumptions of secondary pump, ventilator of air conditioner box and water chiller unit under different outlet temperatures while maintaining the thermal comfort of room, so as to find out the outlet temperature setting with the combination of the least power consumption. Accordingly, thesis builds a set of control system, adopting the fuzzy theory to control the frequency of compressor of water chilling unit, secondary pump and ventilator of air conditioner box, so as to realize the thermal comfort of room and fixed outlet temperature. According to the experimental results, when the outlet temperature of chilling water is set as 12℃, the thermal comfort of room can be maintained at 0.5 and the energy can be saved effectively.
