A vehicle air conditioning system includes an in-vehicle air conditioner that includes a refrigerant circulation circuit including a compressor and an evaporator; a weather information acquiring section configured to acquire weather information at a current location of a vehicle; an evaporator drying determining section configured to estimate a water retention amount of the evaporator based on the weather information acquired by the weather information acquiring section and an operation state of the in-vehicle air conditioner, and to determine whether the evaporator is in a dry state; and a compressor stop permitting section configured to output a permission signal for permitting stop of the compressor on a condition that the evaporator drying determining section determines that the evaporator is in the dry state.
AUTOMATIC WINDSHIELD DEFROSTING SYSTEM
A climate control system for a vehicle comprises a defroster assembly having a temperature sensor that detects an interior temperature of an interior of the vehicle, a camera disposed within the interior that has a lens facing a windshield, and at least one vent directed at the windshield. A body controller that, responsive to a temperature of the interior being less than a temperature threshold, and a light refractive index of the windshield being less than an opacity threshold, outputs a status of the windshield. A telematics communication system that, responsive to the status from the body controller, transmits a notification to an application stored on a mobile telecommunications device.
Control Modification Based on Perceived Environmental Condition
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.
SMART HEATING AND RECIRCULATING AIR MANAGEMENT (RAM) HEATING, VENTILATION, AND AIR CONDITIONING (HVAC) ASSEMBLY AND METHOD
A method for smart heating and Recirculation Air Management (RAM) using an HVAC assembly for a vehicle is disclosed. The method involves obtaining a first air pressure at a first fresh air inlet configured for allowing passage of fresh air in proportion to a first degree of aperture of the first fresh air inlet and the first air pressure, obtaining a second air pressure at a first recycled air inlet configured for allowing passage of recycled air in proportion to a second degree of aperture of the first recycled air inlet and the second air pressure, identifying a required mixed air pressure based on a combination of the first air pressure and the second air pressure, and dynamically modifying the first and second degrees of aperture to obtain the required mixed air pressure which remains constant regardless of parameters associated with the inside passenger cabin of the vehicle.

A vehicle air conditioning system, including: a vehicle interior environmental information acquisition unit that acquires environmental information of a vehicle interior; a vehicle exterior environmental information acquisition unit that acquires environmental information of surroundings of the vehicle; a sensible temperature prediction unit that predicts a sensible temperature of an occupant of the vehicle after a predetermined amount of time has elapsed, based on the environmental information acquired by the vehicle cabin interior environmental information acquisition unit and the vehicle cabin exterior environmental information acquisition unit; and an air conditioner controller that controls an air conditioner based on information regarding a future sensible temperature of the occupant which has been predicted by the sensible temperature prediction unit and a comfortable sensible temperature of the occupant which is stored in a storage unit.
DETECTING AND MITIGATING WINDOW CONDENSATION
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.
Device and method for icing prevention regulation for heat pump evaporators
The invention relates to a device and a method for icing prevention regulation for a heat pump evaporator (3) in air conditioning systems of vehicles, composed of a subsection (1) of a refrigerant circuit which can be operated both as a heat pump and also as an air conditioning system. The device comprises the heat pump evaporator (3), an electrical or mechanical refrigerant compressor (4), a cooler fan (9) which is attached to the heat pump evaporator (3) and which draws ambient air (11) upstream from and through the heat pump evaporator (3) at an adjustable flow speed, and which thus permits a permanent flow of ambient air (11) over the heat pump evaporator surface, a first temperature sensor (6) in or on the refrigerant line (5, 5a) upstream from the heat pump evaporator (3) with respect to the heat pump operating direction, and a control and regulating unit (8). The control and regulating unit (8) is connected via signal lines (10, 10a, 10b, 10c, 10e) at least to the first temperature sensor (6), to further sensors, in particular for detecting the ambient air temperature (Tu) and the vehicle speed (V.sub.F), to the expansion valve (2), to the cooler fan (9) and to the refrigerant compressor (4) for the direct or indirect regulation of the flow cross section of the expansion valve (2) and the rotational speed of the electric refrigerant compressor (4) or of the regulating valve of the mechanical refrigerant compressor (4) and for the actuation of the cooler fan (9) of the vehicle during heat pump operation.
DEFROSTING CONTROL DEVICE, AIR CONDITIONER AND DEFROSTING CONTROL METHOD THEREFOR
Provided are a defrosting control device, an air conditioner and a defrosting control method therefor. The device includes an airbag device, wherein the airbag device includes a mounting support (1), an airbag (2) and an inflation mechanism. When an air conditioner to be controlled enters a defrosting mode, the inflation mechanism inflates the airbag (2) such that same forms an airbag layer to isolate an outdoor heat exchanger of the air conditioner to be controlled from flowing air outside the outdoor heat exchanger. The defrosting control device can achieve the beneficial effects of a small defrosting heat loss, a good defrosting effect and a good user experience.
VEHICLE AIR CONDITIONER
A vehicle air conditioner capable of making a determination that the dehumidification is unnecessary in a vehicle interior early to make a prompt transition from a dehumidifying mode to a heating mode and reduce power consumption is provided. A control device executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator, decompress the refrigerant, and then let the refrigerant absorb heat in an outdoor heat exchanger 7, and a dehumidifying mode to let the refrigerant flow into the outdoor heat exchanger without flowing to the radiator to radiate heat therein, decompress the refrigerant, and then let the refrigerant absorb heat in a heat absorber 9 and let an auxiliary heater 23 generate heat. The control device shifts from the dehumidifying mode to the heating mode on the basis of the heat absorber suction air temperature Tevain being lowered more than a target heat absorber temperature TEO.
