The cooling system includes a refrigerant compressor connected to a primary and secondary section; an external heat exchanger; an evaporator; a heating register; a primary section valve which is closed in the air heat pump operation; and a secondary section valve which is open in the air heat pump operation. The method includes closing of the secondary section valve; opening of the primary section valve, so that refrigerant flows directly from the refrigerant compressor to the external heat exchanger; and setting an inlet-side pressure level of the refrigerant on the external heat exchanger to a target pressure which corresponds to a condensation temperature (Tkond) of the refrigerant in the range: 2° C.≤Tkond≤20° C., in particular 4° C.≤Tkond≤10° C.

Driven lift axles and associated systems and components are provided for use on heavy duty trucks, trailers, and/or other vehicles. Driven lift axle systems may include one or more motors mounted to the lift axle to provide torque to drive one or more wheels of the lift axle. Various mounting configurations of such motors are possible, such as arranging a motor on the axle to provide torque at a conventional driveshaft input by interfacing with a differential drive gear, positioning a motor at each of the wheel ends of the axle to provide torque directly to the wheels, etc. Each wheel can be driven by a separate motor, allowing for independent control of the torque applied to each wheel. Lift axles described herein can be suitable for use with various motors capable of applying torque to the axle and/or wheels, such as electric motors, hydraulic motors, internal combustion engines, etc.
