Abstract: | 本研究主要針對太陽電池直驅式冷氣系統應用在電動車,探討不同系統匹配下輻射量對太陽電池發電量、冷氣總耗電量、冷氣運轉時間比(Runtime Fraction,RF)和運轉機率(Operation Probability,OP)的關係。本研究主要分為兩大部分:(1)系統匹配對冷氣運轉時間比(RF)和運轉機率(OP)影響;(2)透過系統最佳控制來提升RF和OP。
本研究發現冷氣系統的運轉時間比(RF)和運轉機率(OP)主要受到系統匹配設計的影響,包括太陽電池、輔助蓄電池、冷氣機,當輔助蓄電池容量增大,但太陽電池容量不變時,冷氣系統的RF和OP僅微幅增加。如提高太陽電池的容量, 冷氣系統的RF和OP都有顯著增加。比較不同冷氣系統,太陽電池仍是決定其RF和OP的重要因素。 本研究亦探討透過系統最佳控制來提升RF和OP,在天氣狀況不同時,可以控制冷氣機風扇以最低耗能產生最大製冷量,達到最佳製冷效果,或追蹤最佳價值函數以提升系統效率,維持冷氣系統最佳運轉。 The purpose of this research is to apply solar air-conditioning system on electric vehicle (EV). The system matching design is studied experimentally to find out the relationship between incident solar radiation, solar power generation, power consumption of air-conditioning system, runtime fraction (RF), and operation probability (OP). This research focuses on two main topics: (1)the effect of system matching design on RF and OP of air-conditioning system;(2)develop an optimal control technology to improve RF and OP of air-conditioning system. It is found from this research that RF and OP of air-conditioning system do not increase with increasing battery capacity if PV installed capacity not increased. High RF and OP can be obtained if the sizes of PV and battery are properly matched. This research also develops an optimal control technology to improve RF and OP by controlling the fans of the air-conditioning system to provide highest cooling capacity and maintain at the lowest energy consumption. A tracking control system based on the newly defined cost function (Fc) is developed and is proven to be able to improve the system efficiency. |
