直接蒸发式盘管外蓄冰机理的试验研究

直接蒸发式盘管管外蓄冰效率比间接媒的管外蓄冰要高，本文主要针对在蓄冷罐中蒸发式盘管管外蓄冰的机理进行试验研究，得出蓄冰量以及水的初始温度随时间的变化规律。

Experimental research on the ice-formation mechanism outside a coil tube due to internal direct evaporation

In recent years, ice thermal storage technology and its application in HVAC in commercial building has been paid more attention due to it(s ability in shifting peak load for electrically driven refrigerators. Thermal storage with water-ice solid-liquid phase change belongs in those processes with fixed phase change temperature, and can realized high-density storage in a limited space. The purpose of this paper focused mainly on the experimental research on the mechanism of the ice-storage processes on the external surface of the coil in the ice storage tank. The dependence of the change rates of the ice inventory and the initial temperature of the cooling water on time was also studied.
