An air conditioner is configured to be switchable between a heating mode and a cooling mode. In the cooling mode, a high-temperature heat medium circulates between a high-pressure side refrigerant-heat medium heat exchanger and a high-temperature heat medium-outside air heat exchanger in a state where a refrigerant circulates in an air-cooling heat exchanger. In the heating mode, the high-temperature heat medium circulates between the high-pressure side refrigerant-heat medium heat exchanger and an air-heating heat exchanger, while a low-temperature heat medium circulates between a low-pressure side refrigerant-heat medium heat exchanger and a low-temperature heat medium-outside air heat exchanger, in a state where the refrigerant circulates in the low-pressure side refrigerant-heat medium heat exchanger.

A motor vehicle air-conditioning line valve arrangement includes a line valve having an air-conditioning line body which is of substantially closed design in a transverse plane, and a fiber nonwoven arranged on an inside in the air-conditioning line body and having a nonwoven mat to which a large number of nonwoven fibers are fixed. The nonwoven fibers are fixed to the nonwoven mat at one end and configured to be electrostatically charged by the nonwoven mat. An electrical charge generator is electrically connected to the nonwoven mat and configured to electrostatically charge the fiber nonwoven, so that the electrostatically charged nonwoven fibers straighten toward a center of the air-conditioning line body in such a way that they close an open flow cross section of the air-conditioning line body.

An electric drivetrain for installation in a vehicle chassis. A generator coupled to an engine generates electric power for charging an array of batteries. The vehicle, including components and subsystems, may be powered electrically from the batteries, allowing the engine and generator to be easily replaced or customized for an industry, geographic region, fuel type, or a set of emission requirements. A thermal management system may determine a battery temperature for the set of batteries and cause one or more of a coolant system, a refrigerant system, an exhaust gas system, or an ambient air heat exchanger to add heat to the set of batteries or transfer heat away from the set of batteries.
