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.
Key words:  metallic materials      hydrogen storage alloy      air conditioner      COP
