Coolant flowing from a compressor passes through a heat exchanger and opening-degree adjustable type of expansion valves for heating, and an external heat exchanger. The coolant passing through the external heat exchanger is capable of passing through an expansion valve and a heat exchanger for cooling, and an expansion valve and a heat exchanger for cooling a battery. A grille shutter to change an introduction state of traveling air is provided in front of the external heat exchanger. When pressure of the coolant (particularly, pressure of the coolant at a timing after the coolant passes through the external heat exchanger) is a specified pressure or lower, the grille shutter is closed, whereby the heat-exchange performance of the external heat exchanger is lowered.

A device for a ventilation system. An air-conditioning unit comprising a rear wall is arranged such that it is oriented, with the rear wall thereof, towards the module or space to be ventilated such that it is to be reached from said module or space. An interface for air output is arranged on the rear wall, said interface being divided into a plurality of air output points. Said air output points are arranged in different positions on the rear wall. Since all of the air output points do not need to be used, a controller for controlling the air output, which can prevent or enable the air output at the air output points, are associated with the air output points.

An air deflector bar extends parallel to an upper edge of a front windscreen of a motor vehicle. The air deflector bar includes an air deflection channel that extends along its length. The air deflection channel is concavely delimited in cross section by means of a first side that butts against the front windscreen and a second side that is connected to the first side and is at a distance from the first side. The inner surface of the second side of the air deflector bar is oriented toward an edge of a dashboard of the motor vehicle, which edge delimits the dashboard toward a passenger interior.

A vehicle vent assembly includes a first flow channel selectively operating a primary airflow. A second flow channel selectively operates a first secondary airflow that exerts a first pressure on the primary airflow. A third flow channel selectively operates a second secondary airflow that exerts a second pressure on the primary airflow. The first and second secondary airflows control a direction of the primary airflow. The first pressure includes a positive or negative pressure, and the second pressure includes a respective negative or positive pressure.

Some embodiments provide a vehicle climate control system for controlling climate conditions in various cabin regions of a vehicle cabin, where the climate control system is configured to control one or more vehicle components to change the set of climate conditions associated with one or more cabin regions to approximate a set of optimal comfort conditions. The climate control system controls various vehicle components to control climate conditions, including window assemblies, sunroof assemblies, etc. The climate control system determines optimal comfort conditions which optimize perceived temperature of various occupant body parts and maintain various climate characteristics within one or more sets of thresholds. Output configurations of various vehicle components can be determined based at least in part upon determined optimal comfort conditions of various cabin regions. Output configurations can be generated based at least in part upon various control mode priorities.

A module for accommodating electronic circuitry which advantageously is able to take advantage of air in a climate system for cooling of the electronic circuitry. In one aspect, there is provided a module for accommodating electronic circuitry in a vehicle, the module includes: at least one attachment surface for attachment of electronic circuitry thereon, an air guiding structure for receiving an air flow for cooling of the attachment surface, the air guiding structure having a wall member including the attachment surface such that the wall member provides a thermal path between the attachment surface and the air in the air guiding structure, wherein the air guiding structure includes an inlet configured to receive air for cooling of the attachment surface wherein the air flow is an air flow used for climate control in the vehicle.

A vehicle air-conditioning control system includes a controller that controls a blow outlet drive device and a plate member drive device based on a sensed result of a seat back state sensing device. When a reclined state of the seat back is sensed, the controller controls the blow outlet drive device and thereby places an air-flow direction change mechanism in a predetermined position to direct conditioning air, which is blown from the blow outlet, such that the conditioning air collides to a plate surface of a plate member. At this time, the controller also controls the plate member drive device to place the plate member in a predetermined position, so that the conditioning air, which collides to the plate surface of the plate member, reaches a specific part of an occupant who is on the seat having the seat back placed in the reclined state.

An air outlet device for an air conditioner includes a housing that also serves as an air outlet, swingable fins supported by the housing, a pinion gear portion that can swing with the fins, a rack gear portion that meshes with the pinion gear portion, and an operation portion that can linearly move with the rack gear portion. When the fins are swinging to a maximum swingable angle, a rack tooth portion of the rack gear portion, which meshes with the pinion gear portion, is a rack large tooth portion that is formed larger than the adjacent rack tooth portions.

An electronic device that automatically modifies an environmental control is described. During operation, the electronic device may acquire, using the one or more sensors, a measurement within an environment that is external to the electronic device, where the measurement includes a non-contact measurement associated with a window or one or more biological lifeforms in the environment. Then, the electronic device may determine an environmental condition based at least in part on the measurement. Next, the electronic device may automatically modify the environmental control associated with the environment based at least in part on the environmental condition. For example, the environmental condition may include perception of temperature in the environment by a biological lifeform in the environment, and the environment control may adapt a temperature in at least a portion of the environment that includes the biological lifeform.

A system for detecting and mitigating window condensation for a vehicle includes an interior camera and a heating, ventilation, and air conditioning (HVAC) system. The system also includes a controller in electrical communication with the interior camera and the HVAC system. The controller is programmed to determine an opacity of a first window of the vehicle using the interior camera, compare the opacity of the first window to an opacity threshold, and adjust the HVAC system to decrease the opacity of the first window of the vehicle in response to determining that the opacity of the first window is greater than or equal to the opacity threshold.
