A method for air conditioning a vehicle seat that is occupied by a person and that comprises at least one seat ventilation system, wherein at least one humidity sensor is arranged in a seat part and/or a backrest part of the vehicle seat as an actual humidity value transmitter for the absolute air humidity within the cushion part of the at least one seat part and/or backrest part so that a target state of comfort for a person seated on the vehicle seat can be accomplished via a control and regulating device through engagement of the seat ventilation system, wherein the target state of comfort can be controlled to a specifiable target humidity limit value through variation of the air flow of the seat ventilation system as a function of at least one control algorithm that evaluates the detected actual measured humidity value.

An air handling system for distributing airflow in a vehicle is disclosed and includes a passenger compartment configured to contain one or more occupants, a cargo compartment, and a flow regulating valve configured to actuate into a commanded position to apportion airflow between the passenger and cargo compartments. The air handling system also includes one or more processors in electronic communication with the flow regulating valve and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the air handling system to receive one or more signals indicating a total available airflow rate available to the vehicle and a system configuration. The one or more processors instruct the flow regulating valve to actuate into a commanded position. The commanded position is calculated based on at least a target cargo airflow rate.

A door sensor is configured to detect open or closed status of a door and is configured to provide door status information to the controller. The control signals from the controller are based on a combination of the occupancy information and the door status information.

An embodiment vehicle includes an air conditioner, a plurality of odor sensing modules provided in an interior of the vehicle or inside the air conditioner, each of the odor sensing modules including a plurality of gas sensors, and a controller configured to determine whether to initiate a process of determining an occurrence of a bad smell based on state information of the vehicle or state information of the air conditioner, in response to a determination to initiate the process of determining the occurrence of the bad smell, to determine odor data based on an output of at least one of the odor sensing modules, to determine whether the bad smell has occurred based on the odor data, and in response to a determination that the bad smell has occurred, to control to provide notice of or to remove the bad smell.

A recreational vehicle air conditioner and methods of operating a recreational vehicle air conditioner are provided. The recreational vehicle air conditioner may be configured for, and the method may include, receiving a mode selection input comprising one of a thermostat mode and a direct control mode. The recreational vehicle air conditioner may further be configured for, and the method may further include, operating the recreational vehicle air conditioner independently of an external display device when the mode selection input is thermostat mode and operating the recreational vehicle air conditioner in response to one or more commands from the external display device when the mode selection input is direct control mode.

A reheating process for operating a cooling system having a heat pump function for a motor vehicle. The reheating process includes steps of determining a heat differential value by comparing a heat emission actual value at the heating register to a heat emission target value, and adjusting at least one operating setting of the cooling system, so that the power consumption in the cooling system is increased if the heat differential value is greater than 0 and less than a heat differential threshold value.

A vehicle air-conditioning device includes a compressor, a heating unit, an outside air heat exchanger, a wind speed regulation unit, and a controller. The heating unit includes a heating heat exchanger and heats ventilation air supplied to a space to be air conditioned using a high-pressure refrigerant as a heat source. The wind speed regulation unit regulates a wind speed of air supplied to the outside air heat exchanger. The control unit performs, as a defrosting operation of defrosting the outside air heat exchanger, a dry defrosting mode for evaporating and removing frost adhering to the outside air heat exchanger in a state where the outside air is at a low temperature. In the dry defrosting mode, the controller causes the wind speed regulation unit to supply air to the outside air heat exchanger at a wind speed in a range determined to promote evaporation and removal of frost.

A system and method are described for controlling a vehicle interior environmental condition. A biometric sensor senses a biometric condition of a vehicle seat occupant and generates a sensed biometric condition value. A controller receives the sensed biometric condition value, a sensed interior environmental condition value, and a sensed exterior environmental condition value. Each of multiple exterior environmental condition values has an associated biometric condition value defined as optimal for the vehicle occupant. The controller determines the optimal biometric condition value associated with the sensed exterior environmental condition value, compares the optimal biometric condition value to the sensed biometric condition value, and in response to a difference between the optimal biometric condition value and the sensed biometric condition value, generates a control signal to control an actuator to control the controllable interior environmental condition to reduce the difference between sensed biometric condition value and the optimal biometric condition value.

An air outlet apparatus for an interior of a motor vehicle includes a first ventilation gap and a second ventilation gap, which are spaced apart from each other, a decorative element, which is coupled to a fitting covering for the motor vehicle and arranged between the first and the second ventilation gap, and a control unit, which is coupled to the decorative element and has a first regulating element and a second regulating element. An intensity of an air flow through at least one of the ventilation gaps and, by way of the second regulating element, an alignment of the air flow through at least one of the ventilation gaps can be adjusted independently of each other.

An automatic air outlet system for supplying air into a vehicle interior of a vehicle, wherein the automatic air outlet system includes a plurality of air outlets that are motorized and may be automatically adjusted and that respectively include a plurality of setting parameters, a storage unit for storing a plurality of ventilation situations, wherein in the case of each of the plurality of ventilation situations a specific configuration of the setting parameters of each air outlet of the plurality of air outlets is specified, the configuration being adjusted to the corresponding ventilation situation, a specification unit for the purpose of specifying a ventilation situation to the plurality of ventilation situations that are stored in the storage unit, and a control unit for the purpose of controlling the plurality of air outlets such that the air outlets fulfil the ventilation situation that is specified by the specification unit.
