Claim Text:
1. A vehicle comprising: wheels on which the vehicle travels; an electric traction motor for rotating at least some of the wheels to propel the vehicle; a battery bank on-board the vehicle for operating the electric traction motor; a cabin for a driver of the vehicle; a climate control system for the cabin comprising at least one liquid-to-air cabin air heat exchanger in heat exchange relation with air in the cabin, a refrigerant compressor, an electric compressor motor operated by the battery bank for operating the refrigerant compressor to circulate refrigerant in only a single refrigerant loop having only a single refrigerant-to-liquid cold side heat exchanger, the refrigerant circulating from the compressor through a refrigerant-to-liquid hot side heat exchanger within which refrigerant condenses, then through an expansion valve, then through the only single refrigerant-to-liquid cold side heat exchanger within which refrigerant that has passed through the expansion valve expands, and then back to the refrigerant compressor, the climate control system further comprising a first liquid flow loop for circulating liquid first through the refrigerant-to-liquid hot side heat exchanger or the only single refrigerant-to-liquid cold side heat exchanger and then through the at least one liquid-to-air cabin air heat exchanger; and power electronics associated with the battery bank and the electric traction motor, and a second liquid flow loop for circulating liquid through the only single refrigerant-to-liquid cold side heat exchanger and at least one of the electric traction motor, the battery bank, and the power electronics.
