The Direct Neural control Applied to Temperature Control for Energy Saving Air-conditioning System

直接類神經網路控制應用於節能空調系統溫度控制

摘要


節能空調系統在負載降低時常降低壓縮機轉速達成節能功能,因此採用變冷媒流量(VRF)空調系統,藉由改變壓縮機轉速改變冷媒流量。為改善馬達溫度上升問題,近年採用直流無刷馬達壓縮機應用於空調系統則在寬廣速度範圍操作下沒有過熱的疑慮。本研究建立溫度反應參考模型,採用特定學習架構之模式參考直接類神經網路控制,應用於變冷媒流量空調系統溫度控制,可以達成變冷媒流量空調系統節能目的,並以數值模擬分析研究方法,應用於空調系統溫度反應及節能效能。

The energy saving air-conditioning systems can decrease power consumption under low cooling load condition. The variable refrigerant flow (VRF) air-conditioning systems provide variable refrigerant flow by changing the speed of compressor for energy saving. The compressors droved by a Brush less DC (BLDC) driver will improve the high heat generation problem in low load operation conditions. This study applies the direct neural control (DNC) with specified reference model to control the room temperature for a VRF air-conditioning system. The simulation results show the time response of room temperature will follow the responses of the reference model with better adaptability than the conventional PID control.
