本計劃之目的在於研究蓄冷式冷凍儲能材料，利用相變化儲能材料，將物質於離峰時間先行蓄冷後，再於適當的時間放出其儲存冷能之目的，並可提升低溫物流輸送系統技術之高效率、低污染、實用化與低成本之低溫物流輸送系統技術此儲能材料為單成份或多成份的無機性相變化儲能介質其特性為在凝固或溶化時，具有高熱能儲存密度、高熱傳導能力、特定的相變化溫度及可重複使用等特質。本研究使用三種儲能材料，利用此相變化材料之水溶液，在形成固液相平衡時之共晶物組成時的低共晶溫度及高潛熱值(latent heat)之性能，來作為蓄冷式冷凍系之儲能介質，不同的測試條件下可維持在溫度從-15℃至-33℃，而�皕驕�持的時間為3小時到14小時之間。
The purpose of this research is to develop a highly efficienty cold logistic system with energy storage materials which can transform their phase states at different temperatures. In the mean time, this research can improve the design and manufacturing technologies with an energy saving, low pollution and low cost of the cold logistic system. The energy storage materials which can release (or absorb) the thermal energy during freezing (or melting), can be either single inorganic phase change component or multi-inorganic-components with large specific heat capacity, high heat transfer rate, desired transition temperature and repeatable usage. In this research, three kinds of the high latent heat eutectic solutions were used to maintain the multi-temperature cold box within a certain operating time. From the results, the cold box was maintained on the temperature from-15℃ to -33℃ within 3 to 14 hours.
