The invention provides a method and a system for instantaneous cabin heating of a vehicle. Methods and systems are presented for providing heat to a vehicle, whereby a refrigerant loop is operated to heat a cabin of the vehicle via heat generated by a compressor and heat generated by a resistive heating element. The heat generated by the compressor and the heat generated by the resistive heating element are transferred to the refrigerant before being transferred to the cabin. In one example, in a first mode, an evaporator bypass valve on an evaporator bypass conduit of an A/C system is opened to cause refrigerant to bypass an evaporator of the A/C system to raise a temperature of refrigerant in a refrigerant loop; and in a second mode, closing the evaporator bypass valve to direct refrigerant through the evaporator, in which heat is released to an air flow directed to the cabin through the evaporator.

    本公开提供了“用于车辆的瞬时车厢加热的方法和系统”。提出了用于向车辆提供热量的方法和系统,由此操作制冷剂环路以经由通过压缩机产生的热量和通过电阻加热元件产生的热量来加热车辆的车厢。由压缩机产生的热量和由电阻加热元件产生的热量在被传递到车厢之前被传递到制冷剂。在一个示例中,在第一模式下,打开A/C系统的蒸发器旁通导管上的蒸发器旁通阀以使制冷剂绕过A/C系统的蒸发器以升高制冷剂环路中的制冷剂的温度;并且在第二模式下,关闭蒸发器旁通阀以引导制冷剂通过蒸发器,其中热量被释放到穿过蒸发器的被引导到车厢的空气流。
