A motor vehicle heating system includes an internal combustion engine, an exhaust system, a coolant circuit, and a heat storage system that is connected to the exhaust system via at least one heat storage device. The heat storage system is adapted to be coupled to the coolant circuit such that heat can be transferred between the heat storage system and the coolant circuit. The heat storage system includes a thermochemical storage material. Furthermore, a motor vehicle having such a heating system is provided.

A vehicle air conditioner includes a bypass passage configured to cause a coolant to circulate while bypassing a heater core, a switching device set to switch between a first mode in which the coolant flows through the bypass passage and returns to an internal combustion engine while bypassing the heater core and a second mode in which the coolant flows to the heater core, a coolant-temperature sensor that detects a temperature of the coolant at a part through which the coolant flows in both the first mode and the second mode, and a control unit that controls an operation of a blower based on the coolant-temperature control data. Furthermore, first and second calculating portions are configured to calculate the coolant-temperature control data in the first and second modes, respectively. The first calculating portion calculates the coolant-temperature control data based on the temperature of the coolant detected at start-up of the internal combustion engine, and the second calculating portion sets, as the coolant-temperature control data, a temperature lower than the detected temperature of the coolant.

The present invention relates to a vehicular heating device comprising: a vehicular engine cooling unit for connecting an engine, a water pump, and a radiator on a first cooling water circulating line to cool the engine; and a vehicular indoor space heating unit for connecting the engine, the water pump, and a heater core on a second cooling water circulating line to heat an indoor space of the vehicle, wherein the vehicular heating device comprises a heating means mounted on the second cooling water circulating line to heat cooling water supplied to the heater core. According to the present invention, the heating performance of the cooling water, which is supplied to the heater core during an initial cold start of the vehicle is improved, thereby increasing the indoor heating efficiency of the vehicle during a winter season.

A vehicular heat management system includes a heat medium circuit, a heat source portion, and a device. A heat medium cooling an engine circulates in the heat medium circuit. The heat source portion heats the heat medium. The device is configured to function and heat the heat medium when the heat medium flowing into the device is at or above a predetermined temperature. When the engine is being warmed up, heat generated by the heat source portion is supplied to the device in preference to the engine. According to this, since the heat generated by the heat source portion is supplied to the device in preference to the engine when the engine is being warmed up, the engine can be warmed up early.

A vehicle warm-up control apparatus includes: a motor; an inverter; an electric storage device; a boost converter connected to a low-voltage-side power line and a high-voltage-side power liner; and a control unit for controlling the inverter and the boost converter, the boost converter including a first switching device as an upper arm, a second switching device as a lower arm, and a reactor. Further, the second switching device is composed of a semiconductor device variable in resistance value, and when warm-up is requested, the control unit executes warm-up control to set the resistance value of the second switching device higher than the resistance value during operation when the warm-up is not requested, and supply heat generated in the second switching device by passing current through the second switching device to a device for which the warm-up is requested.

A system for warming an engine. The system includes an engine coolant system that directs warm engine coolant to the engine to heat the engine. A heat pump system warms the engine coolant.

A thermal energy storage system for a vehicle. The system includes a tank that is external to the vehicle. The tank is configured to receive liquid from the vehicle, and store the liquid at or above a predetermined temperature prior to the liquid being returned to the vehicle.

Methods and systems are provided for heating a cabin of a vehicle using an alternator of the vehicle. In one example, a method may include operating in a first operating mode to heat a cabin of a vehicle, the first operating mode including shorting an alternator output of an alternator of the vehicle to ground, and closing a coolant valve positioned between a coolant system of an engine of the vehicle and an alternator coolant circuit.

A mobile heating system is disclosed. In one embodiment, the system includes an enclosure defining a plenum that houses a fan and an internal combustion engine. The heating system also includes a hydraulic circuit including a hydraulic pump operably coupled to the internal combustion engine and a first heat exchanger located in the plenum and in fluid communication with the hydraulic pump. The hydraulic circuit also includes a hydraulic motor operably coupled to the fan wherein the hydraulic motor is in fluid communication with and driven by the hydraulic pump. A first valve is disposed between the hydraulic pump and the heat exchanger and is configured to restrict fluid flow and to increase a fluid pumping pressure of the hydraulic pump. A second valve is located upstream of the first valve and is configured to selectively direct hydraulic fluid between the first valve and the hydraulic motor.

A cooling device includes: an air blast passage; a heater core that is disposed in the air blast passage; an air blast volume adjusting member that is opened and closed to adjust an air blast volume which flows in the heater core; a flow rate adjuster that adjusts a flow rate of the coolant which is introduced into the heater core; and a controller. The controller sets the flow rate of the coolant which is adjusted by the flow rate adjuster to be less than a lower limit value of an adjustable range of the flow rate of the coolant which is adjusted by the flow rate adjuster in a vehicle compartment air-conditioning state in which the air blast volume adjusting member allows an air blast to flow to the heater core when the air blast volume adjusting member fully closes the heater core side of the air blast passage.
