【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。更多还原

【Abstract】 Dependence of coefficients of performance(COP) on various parameters of metal hydride automobile air-conditioning system is investigated.The results show that working temperature,flat 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.更多还原
