| 中文摘要 |
國內冷凍冷藏櫃近年數量大幅增長，目前普遍存在壓縮機啟停頻繁的現象，溫度與耗電表現不佳。若能預測冷櫃所需之熱負載，並配合變頻器調整頻率恰好供應需求冷能，系統便可穩定高效運轉。本研究將針對雙門玻璃冷藏櫃建立壓縮機製冷能力模型與熱負載預測模型，作為壓縮機變頻控制策略之依據。實現可依據各種環境變化，由壓縮機變頻恰好供應略高於熱負載之冷能，穩定高效率運轉之目標。最終配合工研院開發之直流無刷壓縮機變頻驅動器，提升國內智慧變頻冷凍冷藏櫃之普及率，全面提升溫度與耗電表現。 |
| 英文摘要 |
The number of refrigerated cabinets in Taiwan has increased significantly in recent years. At present, the phenomenon of frequent start and stop of compressors is common, and the performance of temperature and power consumption is not good. If the heat load required by the refrigerated cabinets can be predicted, and the operating frequency of the compressor can be adjusted to meet demand, the system can run stably and efficiently. This study will establish a compressor refrigeration capacity model and a heat load prediction model for a double-door glass refrigerated cabinet as the basis for the frequency control strategy of the compressor. Realize the goal of stable and high-efficiency operation by supplying cooling energy slightly higher than the heat load by frequency control of the compressor according to various environmental changes. Finally, cooperate with the brushless DC compressor variable frequency drive developed by the Industrial Technology Research Institute to increase the penetration rate of domestic smart refrigerated cabinets, and comprehensively improve the temperature and power consumption performance. |
