Abstract

See full text

Methods and system for providing heat to a vehicle are presented, 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 a refrigerant before it is transferred to the cabin. In one example, in a first mode, an evaporator bypass valve on an evaporator bypass conduit of the A/C system is opened to route the refrigerant around an evaporator of the A/C system to increase a temperature of the refrigerant in the refrigerant loop; and in a second mode, the evaporator bypass valve is closed to route the refrigerant through the evaporator, where heat is released to a flow of air across the evaporator that is directed to the vehicle cabin.
