摘　　要：建立了适用于常规空调工况的蓄冷器的数学模型,研究了一种新型的相变材料在蓄冷器蓄冷动态特性,采用显热容法对蓄冷器模型进行数值求解,研究载冷剂流量和进口温度对蓄冷器蓄冷的影响,获得载冷剂流量和进口温度对蓄冷器蓄冷的影响曲线。结果表明水流量的增加对总的蓄冷量的增加非常有限,而进水温度的变化对蓄冷量的有一定的影响。旨在为常规空调相变蓄冷技术的应用提供应用理论基础和技术储备。Mathematical model of the storage tank for air-conditioning condition was established,the dynamics Character of a new type of PCM in the storage tank was studied,and the model was numerical simulated by the method of heat capacity.Effects of flow rate and inlet temperature of Heat Transfer Fluid（HTF） on charging process of the storage tank were obtained.The results show that no appreciable change in the total cold thermal energy storage is observed for the increase of flow rate,whereas the improvement of the total cold thermal energy storage due to the decrease of inlet temperature is detectable.This can make the design of PCM stores more rationalized and offer theory evidence and data for the application of cool storage technology.
