A cargo transport heating system is utilized for a truck that includes a cargo containment and a combustion engine having a coolant inlet and a coolant outlet. The cargo transport heating system includes a heat exchanger, a coolant pump, and a combustion engine coolant having a low toxicity. The heat exchanger is disposed in the cargo containment, and is in fluid communication with the first coolant inlet. The coolant pump is in fluid communication with the coolant outlet and the heat exchanger, and pumps the combustion engine coolant through the first coolant inlet, the coolant outlet, and the heat exchanger.

A heating system and method for heating the interior of a vehicle, such as a motor vehicle, which has an air-air heat exchanger having a heat storage medium, and which is configured to transfer heat between exhaust air, drawn out of the interior, and intake air, supplied to the interior from the vehicle environment, between the exhaust air and the heat storage medium, and between the intake air and the heat storage medium.

A vehicular heat management system includes a refrigerant circulation line configured to cool or heat a passenger compartment by generating a hot air or a cold air depending on a flow direction of a refrigerant, a cooling water circulation line configured to heat the passenger compartment with waste heat of an engine by allowing cooling water of the engine to circulate through a heater core, a refrigerant-cooling water heat exchanger disposed in the cooling water circulation line to allow the refrigerant and the cooling water to exchange heat, and an engine cooling water independent circulation unit configured to allow the cooling water passed through the engine to bypass the heater core and the refrigerant-cooling water heat exchanger.

Presented are joint active thermal management (JATM) systems with heat exchanger storage of surplus refrigerant, methods for making/operating such systems, and vehicles equipped with such systems. A JATM system includes a coolant loop that fluidly connects to a vehicle battery system for pumping thereto coolant, an oil loop thermally coupled to the coolant loop and fluidly connected to a vehicle powertrain system for pumping thereto oil, and a refrigerant loop thermally coupled to the coolant loop and operable to circulate refrigerant for heating/cooling a passenger compartment. An electronic controller determines if a current amount of refrigerant in the refrigerant loop exceeds a calibrated threshold for the current operating mode of the JATM system. If so, the controller determines if one of the refrigerant loop's heat exchangers is available to store excess refrigerant. If the heat exchanger is available, the refrigerant loop stores excess refrigerant in the available refrigerant heat exchanger.

A cooling system for a vehicle propelled by an electric machine. The cooling system is arranged, when the vehicle is operated in a braking mode, to control a first and a second radiator valve to direct a flow of fluid from a radiator through a first fluid circuit and prevent the flow of fluid from the radiator to enter the second fluid circuit, control a compressor arrangement to flow a refrigerant in a direction from a heat exchanger to a condenser of a third fluid conduit, and control a second circuit valve arrangement to direct a heat source fluid to circulate through a heat exchanger and an electric heat source.
