[[alternative]]Thermal Comfort Control of Ice Storage Central Air Conditioning System

碩士電機工程學系[[abstract]]空調的大量使用是夏季電力供應吃緊的主因，而台電的冰水主機卸載計畫對抑制夏季空調用電的峰值相當直接而有效，但是在卸載期間的不舒適感是極需克服的問題。儲冷式中央空調系統的儲冷方式主要是利用空調主機在離峰時間運轉製冷，待尖峰時間有大量的空調負荷需求時，再將冷度釋放出來，以達到降低尖峰負載的目的；此外，利用預存的冰水增加卸載期間的冷凍能力，可改善卸載期間因空調主機停止運轉而引發的不舒適。 因此本研究配合中央空調週期性暫停用電排程，引用ASHRAE提出的舒適度控制標準，並選用對於處理非線性問題有良好成效的倒傳遞類神經網路(BPNN)控制器，做可變風量送風機的控制，再利用儲冷式中央空調系統特性，增加冷凍能力，以解決卸載期間的舒適問題，獲得合理的舒適度；此外，也藉由儲冷式中央空調系統預存冰水冷度，拉長卸載時間。[[abstract]]The large capacity of HVAC causes electric power deficiency in Taiwan. The plan of cutting off the HVAC load directly can be applied to reduce the peak load during summer season efficiently, but the problem of discomfort need to be solved. The ice storage central air conditioning system stores up a large amount of cooling water, and discharges cool air during off shift of DLC. This device not only reduces the peak load, but also keeps comfort. This paper adopts the standard of the thermal comfort from the ANSI/ASHERE standard 55-1992. The BPNN controller deals properly with nonlinear problems like air condition. Combining ice storage central air conditioning system increases cooling capacity. This method can reduce the peak load during summer, and balance thermal comfort reasonably during off shift of DLC
