空调系统在交通运输中的应用是一个巨大的挑战，由于频繁波动的负载，导致舒适性下降，甚至健康问题。在我们以前的研究中，一个紧凑的能量存储装置填充PCM的设计和实验测试，显示出巨大的潜力，热舒适性的改善和效率的提高。在这项研究中，充电性能的能量存储装置的列车空调系统进行了实验研究。给出了PCM在充电过程中温度随时间的变化规律。分析了充能系统的充能时间、充能率、热效率和火用效率等充能特性。结果表明，该装置具有良好的传热性能，火用效率可达78%。该装置具有快速充气的特点，适用于汽车空调系统。
Air conditioning system in transport applications is a great challenge due to the frequently fluctuated load which causes comfort degradation and even healthy concern. In our previous study, a compact energy storage device filled with PCM was designed and experimentally tested which showed great potential for thermal comfort improvement and efficiency improvement. In this study, charging properties of the energy storage device for train air conditioning systems are experimentally investigated. Time evolutions of PCM temperature during the charging process are presented. The charging performances including charging time, transient charging rate, thermal efficiency and exergy efficiency are revealed. The results show that the designed device has excellent heat transfer behaviors with exergy efficiency up to 78%. The designed device is feasible to be used in transport air conditioning systems due to the quick charging.
