A method for operating a refrigeration system for a motor vehicle. The method includes setting an operating mode of the refrigeration system having active primary line and inactive secondary line or having active secondary line and inactive primary line; detecting the pressure in the inactive line; and activating and extraction of refrigerant from the inactive line into the active line by lowering the pressure in the active line to a value below the pressure in the inactive line and by opening the relevant valve device.

A vehicle cabin air temperature controller includes a two-position three-way solenoid valve with one inlet to take in coolant supplied by a pump, a first outlet to supply a cooling leg, and a second outlet to supply a bypass leg. The vehicle cabin air temperature controller also includes a controller to control flow of the coolant via the first outlet and the second outlet of the solenoid valve, and a cabin air heat exchanger to obtain an input coolant based on the control of the flow via the first outlet and the second outlet and to provide cooled cabin air to the vehicle cabin. The control of the flow of the coolant via the first outlet and the second outlet controls a flow rate of the input coolant.

A cooling system control method for an autonomous driving controller may include detecting the temperature of the autonomous driving controller by the controller when a vehicle is driving; determining whether a current temperature of the autonomous driving controller is lower than a target temperature by the controller; and terminating the controlling of the cooling system if the condition is satisfied in determining whether the current temperature of the autonomous driving controller is lower than the target temperature.

An air vent assembly includes an air inlet, an air outlet, and a plurality of channels positioned between the air inlet and the air outlet. A first set of fixed vanes is positioned in a first one of the channels. The fixed vanes of the first set are angled or curved in a first direction with respect to a flow vector of the air inlet. A second set of fixed vanes is positioned in a second one of the channels. The fixed vanes of the second set are angled or curved in a second direction with respect to a flow vector of the air inlet. A gate is positioned within grooves of each of the first and second sets of fixed vanes. The gate is configured to regulate a position at which air may enter the first and second channels from the air inlet.
