A vehicle is provided to include a bio-signal sensor that detects a bio-signal of a user, a display device that displays an image and a controller that determines at least one of a positivity of the user or change amount of the positivity of the user based on the detected bio-signal. The controller accumulates a positivity index when at least one of the positivity or change amount of the positivity is equal to or greater than a predetermined positivity or a predetermined change amount of the positivity and transmit a control signal to the display device to display the accumulated positivity index.

An air temperature-controllable module, for a temperature-controllable storage unit, having an air temperature-controllable unit including a useful air temperature-controllable region, a waste air temperature-controllable region, and at least one thermoelectric device including a useful air side and a waste air side, the useful air side connected to the useful air temperature-controllable region and the waste air side connected to the waste air temperature-controllable region, a useful air path for a useful air flow extending from a useful air inlet to a useful air outlet and the useful air temperature-controllable region of the air temperature-controllable unit connecting to the useful air outlet, and a waste air path for a waste air flow extending from a waste air inlet to a waste air outlet and connecting the waste air temperature-controllable region of the air temperature-controllable unit to the waste air outlet.

A system for thermally conditioning and moving a fluid includes a thermoelectric device to convert electrical energy into thermal energy and produce a temperature change in response to an electrical current being applied thereto. The thermoelectric device can include a main-side and a waste side. A fluid moving device can produce a fluid flow that is in thermal communication with the thermoelectric device so that the thermal energy generated by the thermoelectric device is transferred to or from the fluid flow. A flow control valve selectively can direct the fluid flow along a main-side fluid flow path and/or a waste side fluid flow path.

A vehicle ventilation device includes: a calculation unit that calculates at least one of an occupant density and a mask wearing rate in a vehicle based on a detection result of a sensor; and a ventilation control unit that ventilates an inside of the vehicle in accordance with at least one of the occupant density and the mask wearing rate calculated by the calculation unit.

An air conditioning unit, including: a chamber; a fan, in the chamber, for effecting an entry air entering the chamber and an exit air exiting the chamber; and an evaporative unit, in the chamber, for conditioning the entry air; wherein the fan, together with at least part of the chamber, creates a pressure zone, without ejecting air directly to, or without drawing air directly from, the evaporative unit, such that air moves through the evaporative unit substantially through a pressure effect.

The invention relates to a method for defrosting an external-air heat exchanger of an electric vehicle. Contrary to the conventional principle of operating systems in an electric vehicle at the lowest possible output power, according to the invention, high output power is used for the defrosting process, to reduce the defrosting time and thus reduce heat loss.

A method of reducing a temperature inside a vehicle includes: when a current time is the same as a setting time of a vehicle after the vehicle is turned off, measuring, by a controller, a temperature outside the vehicle based on an output signal of an outside air temperature sensor of the vehicle; and discharging, by the controller, air inside the vehicle to the outside of the vehicle by receiving power from a battery of the vehicle and operating a blower motor, which drives a blower, based on an operation time of the blower motor according to the temperature outside the vehicle.

A method for controlling a heating, ventilation, and air conditioning (HVAC) system, may include: allowing, by a controller, only the indoor air to be directed into a housing when the HVAC system operates in a cooling mode and an engine is stopped by an Idle Stop and Go (ISG) system; allowing, by the controller, the indoor air directed into the housing to bypass a heater core; and maintaining, by the controller, a flow rate of the air directed into the housing at a minimum flow rate.

An assembly for a ventilation system of a vehicle is provided. The assembly is configured to use a single actuator to control direction of a vent and additionally control the flow rate of that vent. The assembly may comprise a single rotatable control member with two routes, one route used for controlling flow rate and one route for controlling flow direction. Each route may have a straight portion and curved portion.

A method for controlling air conditioning of a vehicle includes: determining whether an air conditioning control entry condition for battery cooling wind backseat backflow compensation is satisfied from environment information collected from the vehicle; starting air conditioning control for the battery cooling wind backseat backflow compensation if it is determined that the entry condition is satisfied; determining a compensation value corresponding to a current operating level of a battery cooling fan when the air conditioning control for the battery cooling wind backseat backflow compensation is started; compensating for a current control variable value of an air conditioning device component using the determined compensation value; and performing an air conditioning operation for compensation in accordance with a backflow of a battery cooling wind having cooled a battery toward a backseat by controlling a state of the air conditioning device component in accordance with the compensated control variable value.
