摘　　要：制备汽车空调用贮氢合金并研究了操作温度、合金的坪区平直性和滞后程度对合金对循环效率COP值的影响,结果表明:随着高温操作温度的升高COP值先增大后减小,高温操作温度存在最佳工作范围;低温操作温度升高,坪区的平直性系数φ和滞后系数β减小,均有利于得到更高的COP值。Dependence of coefficients of performance （COP） on various parameters of metal hydride automobile air-conditioning system is investigated. The results show that working temperature, fiat plateau and hysteresis influence COP values. With increase of working temperature of hot spot alloy, COP of air-conditioning system firstly increases and then decreases. There is a suitable working temperature range of hot spot alloy range to obtain a higher COP. Higher working temperature of cold spot alloy, flatter plateau and smaller hysteresis, are also beneficial to reaching a higher COP.
