| 摘要 |
A cooling-heating circuit for a powered vehicle, in particular an electric vehicle with a fuel cell, has at least two devices (10,20) increasing the temperature of the cooling-heating circuit and at least two devices (40,50) reducing the temperature of the cooling-heating circuit. The temperature-increasing (10,20) and/or the temperature-reducing devices (40,50) are associated with the cooling-heating circuit at least to some extent according to their operating states, in particular their temperatures. For improved utilization of the waste heat, a heat pump circuit is associated with the cooling-heating circuit. <IMAGE> |
