    Abstract: 融冰釋冷系統的研究目的在於取代耗電量較大的冷氣空調設備，主要是利用離峰時間的電量來製冷並儲存之，以降低尖峰時間之用電負荷。本研究探討具迴流及不具迴流且未移除冰層的融冰釋冷系統，在不同空氣體積流率及不同冰層初始溫度下，求其表面溫度、空氣出口溫度及納塞數(Nusselt number)對時間的關係。結果顯示，表面溫度會隨著時間增加而增加，而空氣體積流率的增加會使得表面溫度及空氣出口溫度上升。此外，在迴流比值提高的情況下，納塞數會相對提高。
    A mathematical model of cool-thermal discharge systems with external recycle under constant volumetric flow rate was developed in the present study. The theoretical predictions were obtained by heat transfer and thermodynamic relation for three specified volumetric flow rate. The calculated results show that the recycle effect can enhance the average Nusselt numbers, and hence, the heat transfer rate is increased accordingly. Three numerical examples of inlet ambient air temperature have been delineated to compute the chilled air temperature and average Nusselt numbers with different volumetric flow rate.
