| dc.description.abstract | 本研究主要針對連續式真空製冰泥系統進行性能分析，以提升系統製冰效率。透過調整製冰時間、輸冰管開啟間隔時間、噴霧水泵流量及冷卻水溫度等參數，找出最佳操作條件，從而增加製冰泥的生成量。
首先，本研究設計了一套連續式真空製冰泥系統，包含閃蒸槽、真空微壓縮機、噴霧水泵、冷卻水系統等核心元件。系統使用乙二醇水溶液在真空環境下的閃蒸冷卻形成製冰泥，實驗冷卻水溫度設定為4℃，乙二醇水溶液濃度為2.5%。 研究顯示，隨著製冰時間的延長，製冰泥量顯著增加。當製冰時間從5分鐘延長至20分鐘時，製冰泥量從1,501克增加至4,328克。輸冰管開啟間隔時間2分鐘時製冰泥量最大，間隔時間過長會使冰泥在閃蒸槽中聚合，減少製冰量。噴霧水泵流量2LPM 時製冰泥量最大，流量過大不利於冰泥生成。 此外，冷卻水溫4℃時製冰泥量最大。隨著冷卻水溫度的增加，製冰泥量顯著下降。當冷卻水溫度提升至7℃及9℃時，系統的冷凝能力下降，真空微壓縮機的壓縮比上升，最終減少蒸發量，製冰泥量顯著減少。 總結來說，本研究找到了提高連續式製冰泥系統製冰效率的方法，適當的輸冰管開啟間隔時間和噴霧水泵流量顯著提高了製冰量，這些發現對未來設計更高效的製冰泥系統具有重要參考價值。 | zh_TW |
| dc.description.abstract | This study focuses on the performance analysis of a continuous vacuum slush icemaking system to enhance ice-making efficiency. By adjusting parameters such as ice making time, ice discharge pipe opening interval, spray pump flow rate, and cooling water temperature, the optimal operating conditions were identified to increase the production of slush ice.
Firstly, a continuous vacuum slush ice-making system was designed, including core components such as a flash tank, vacuum micro-compressor, spray pump, and cooling water system. The system uses an ethylene glycol aqueous solution in a vacuum environment to flash cool and form slush ice. The experimental cooling water temperature was set at 4°C, and the ethylene glycol solution concentration was 2.5%. The study showed that the amount of slush ice significantly increased with the extension of ice-making time. When the ice-making time was extended from 5 minutes to 20 minutes, the amount of slush ice increased from 1,501 grams to 4,328 grams. The maximum amount of slush ice was obtained with a 2-minute ice discharge pipe opening interval. A longer interval caused the slush ice to aggregate in the flash tank, reducing the ice-making amount. The maximum amount of slush ice was obtained with a spray pump flow rate of 2 LPM. An excessively high flow rate was detrimental to slush ice formation. Moreover, the maximum amount of slush ice was obtained at a cooling water temperature of 4°C. As the cooling water temperature increased, the amount of slush ice significantly decreased. When the cooling water temperature rose to 7°C and 9°C, the system’s condensing capacity decreased, the compression ratio of the vacuum micro-compressor increased, ultimately reducing the evaporation rate and significantly decreasing the amount of slush ice. In summary, this study identified methods to improve the ice-making efficiency of the continuous slush ice-making system. Appropriate ice discharge pipe opening intervals and spray pump flow rates significantly increased the amount of slush ice. These findings are valuable references for designing more efficient slush ice-making systems in the future. | en |
