Abstract
A cooling-heating circuit for a powered vehicle, in particular an electric vehicle with a fuel cell, has at least two devices increasing the temperature of the cooling-heating circuit and at least two devices reducing the temperature of the cooling-heating circuit. The temperature-increasing and/or the temperature-reducing devices 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.
Claims12
A cooling-heating circuit for a powered vehicle, having at least two devices that increase the temperature of the cooling-heating circuit, at least two devices that reduce the temperature of the cooling-heating circuit and at least one pump, wherein the temperature-increasing devices and/or the temperature-reducing devices are associated with the cooling-heating circuit at least partly in accordance with their operating states, in accordance with their temperatures.
A cooling-heating circuit for a motor vehicle, having at least two devices that increase the temperature of the cooling-heating circuit, at least two devices that reduce the temperature of the cooling-heating circuit and at least one pump, wherein the temperature-increasing devices and/or the temperature-reducing devices are associated with the cooling-heating circuit at least partly in accordance with their operating states, in accordance with their temperatures, and further comprising a heat pump circuit, in particular a reversible heat pump circuit, associated with the cooling-heating circuit.
