摘要: 通过数值模拟的方法,从稳态和驾驶循环2种工况对供氢系统辅助供冷方案进行评价。仿真结果表明:氢气的高膨胀比有利于空调系统能耗的下降。当环境温度为45 ℃,在中国乘用车驾驶工况下,辅助供冷方案可使空调系统能耗下降5.4%。但辅助供冷方案会给空调系统的稳定运行和座舱温度的控制带来一定的挑战。

Abstract: Through the numerical simulation method, the auxiliary cooling scheme of the hydrogen supply system is evaluated under the conditions of steady state and driving cycle. The simulation results show that the high expansion ratio of hydrogen is beneficial to reduce the energy consumption of the air conditioning system. When the ambient temperature is 45 ℃, the auxiliary cooling scheme can reduce the energy consumption of the air conditioning system by 5.4% under driving cycle in China for passenger vehicles. However, the auxiliary cooling scheme brings some challenges to the stable operation of the air conditioning system and the control of the cabin temperature.
