A fuel cell system includes a fuel cell stack, a first cooling line having first cooling water that passes via the fuel cell stack and circulates therein, a first radiator that cools the first cooling water, an air conditioning system that forms a heating loop with a first cooling line, a first cooling fan that blows exterior air to the first radiator, a first pump that pumps the first cooling water, a valve that switches a flow path of the first cooling water to the fuel cell stack or the first radiator, and a controller connected to the first cooling fan, the first pump, and the valve, and configured to detect a failure of the valve, control RPMs of the first pump and the first cooling fan to respective maximum levels, and control an RPM of a blower of the air conditioning system to a maximum level.

A ventilation device may include a housing, a fluid channel system, a heat exchanger, and a slider arrangement. The slider arrangement may include at least one first slider and at least one second slider arranged within the fluid channel system upstream of the heat exchanger and downstream of the heat exchanger respectively. The first and second slider may be guidable transversely with respect to at least one fluid flow. The first and second slider may each be actuatable. At least one of a volume flow and a mass flow of at least one fluid flow may be at least one of controllable and regulatable via actuation of the first slider. At least one of a predetermined fluid temperature and a predeterminable fluid temperature of a mixed fluid may be settable and at least two fluids may be mixable via actuation of the second slider.

Methods and systems to dissipate heat in a vehicle include a first condenser portion, and a second condenser portion arranged parallel with the first condenser portion. The system includes a fan arranged parallel with the first condenser portion and the second condenser portion. The fan draws air flow from the first condenser portion and the second condenser portion. The system also includes a radiator arranged substantially perpendicular with the first condenser portion and the second condenser portion, and one or more covers controlled to an open or closed position. A controller controls the position of the one or more controlled covers.

An exhaust intrusion mitigation system for a vehicle includes one or more processors and a memory communicably coupled to the one or more processors. The memory stores an enclosure detection module which determines if a vehicle is parked within an enclosure with the engine running. An exhaust module determines a point in time at which one or more vehicle vents should be closed if the vehicle remains in the enclosure and the engine remains on. A mitigation module controls operation of the vehicle to close the one or more vents at the point in time when the vent(s) should be closed.

A method for controlling a climate control system is disclosed. In one example, the climate control system includes adjusting an air mixing valve state and adjusting a displacement of a compressor in response to an energy conversion device load. The method may provide improved climate control in a vehicle cabin during high energy conversion device load conditions.

An airflow control system includes an air blower and an outlet door. The air blower is disposed on a front side in a vehicle traveling direction with respect to an inside of a cabin and disposed inside an engine compartment that houses a propulsion engine. The outlet door opens and closes an air outlet through which an air flow from an inside of the engine compartment is blown to another area on a rear side in the vehicle traveling direction with respect to the engine compartment. The air blower blows an air flow containing exhaust heat of the propulsion engine to the other area through the air outlet while the air outlet is opened by the outlet door.

An autonomous vehicle includes a passenger cabin, a sensor group and a passenger cabin climate control system including a control module. The sensor group includes a passenger cabin odor sensor, an occupancy sensor and a vehicle speed sensor. The control module has a control logic adapted to purge an odor from the passenger cabin in response to data received from the sensor group indicating the presence of an odor in the passenger cabin, an unoccupied passenger cabin and the autonomous vehicle is moving at a minimum predetermined speed for a minimum predetermined time.

In a situation where a temperature in a motor compartment is higher than a temperature of outside air, an inside air introduction rate increasing control is performed in which an inside air introduction rate is changed to be increased on a condition that there is no request for warming an inside of the vehicle cabin, the air conditioner is off, and air is being blown in an outside air introduction mode, and on the other hand, the inside air introduction rate increasing control is prohibited on a condition that there is a request for warming the inside of the vehicle cabin, the vehicular air conditioner is off, and air is being blown in the outside air introduction mode. In this way, heating efficiency can be improved by effectively utilizing the heat in the motor compartment to contribute to warming the inside of the vehicle cabin.

A refrigerated container (10) that includes a container (10), an auxiliary lock (42), and a ventilation system. The container (10) defines an interior space (14) and has a door (30) to selectively permit access to the interior space (14). The auxiliary lock (42) is arranged to selectively inhibit the door (30) from moving from the closed position towards the open position. The ventilation system includes a leak sensor (44) and a controller (48). The leak sensor (44) is arranged to provide a signal indicative of a concentration of a refrigerant within the interior space (14) of the container (10). The controller (48) is arranged to receive the signal and is programmed to command the auxiliary lock (42) to move towards the lock position, responsive to the signal being indicative of the concentration of the refrigerant within the interior space (14) being greater than a threshold.

A roof vent includes a roof disposed on a vehicle and a vent assembly. The vent assembly has at least one vent unit disposed on the roof and configured to enter the roof, a driving unit driving the vent unit, and at least one rack unit applying the driving force of the driving unit to the vent unit. The vent unit enters the roof due to operation of the driving unit.
