  • Patent number: 8463492
    Abstract: A system for controlling air-conditioning in a vehicle includes an input, a sensor, a first offset module, and an evaporator temperature control module. The input receives an input temperature. The first sensor measures a first dewpoint temperature of air adjacent to a windshield of the vehicle. The first offset module generates a second dewpoint temperature based on the input temperature and generates a first offset based on the first and second dewpoint temperatures. The evaporator temperature control module generates a target evaporator temperature based on the first offset.

  • Patent number: 8301335
    Abstract: A system for controlling air-conditioning of a vehicle includes an input, an offset generator module, and an evaporator temperature control module. The input receives an input temperature. The offset generator module receives a psychrometric parameter of air inside the vehicle and generates offsets based on the input temperature and the psychrometric parameter. The evaporator temperature control module generates a target evaporator temperature based on the offsets.

  • Patent number: 7797954
    Abstract: In a cooling system, particularly a cooling system for motor vehicles, including a cooling circuit and a refrigerating circuit which are coupled to one another via a refrigerant/coolant heat exchanger and a third medium/coolant heat exchanger arranged in the cooling circuit, a heat source to be cooled is arranged in the cooling circuit and means are provided for controlling the quantity of coolant flowing through the refrigerant/coolant heat exchanger.

  • Publication number: 20100025125
    Abstract: In a method and apparatus for the operation of a vehicle having a battery with a plurality of series or parallel connected individual cells, a coolant flows through the respective cell housings and/or a battery housing that encloses the entire battery. The coolant is delivered within a coolant circuit by a pump unit, and is thermally coupled with a refrigerant circuit through a heat exchanger. A refrigeration compressor placed in the refrigerant circuit is thermally coupled with the coolant circuit through the heat exchanger, depending on a current ambient temperature and/or a current speed of the vehicle. The speed of the refrigeration compressor may be regulated depending on the current ambient temperature and/or the current speed of the vehicle.

  • Publication number: 20060144061
    Abstract: In a method for operating a climate control system in a passenger compartment of a motor vehicle, the climate control system can be operated in a recirculation mode in which recirculated air is supplied to the passenger compartment or in fresh air mode in which at least a portion of the air supplied to the passenger compartment is fresh air. In its normal operating mode the climate control system is operated in recirculation mode. Upon exceeding a predetermined CO2-threshold value measured in the passenger compartment of the motor vehicle the climate control system is switched to fresh air mode.

  • Patent number: 6078853
    Abstract: A device for use in vehicles with electric or hybrid drive for monitoring the air conditioning of a vehicle based on health and energy consumption readings. The device monitors the operation of the air conditioning to determine when differentials between outside and inside temperature are excessive, and/or inside atmospheric humidity is too low and/or air quality is poor. An occurrence of any of these conditions results in the system suggesting to the driver that he should interrupt travel to the desired destination. In addition, if necessary, the device performs a vehicle range estimate as a function of the selected air conditioning operation.

  • Patent number: 5603476
    Abstract: A filter holder assembly is provided for the optional holding in a motor vehicle at a dust filter alone or a dust filter and an absorption filter which is optionally arranged directly downstream of the dust filter. A frame lower part is provided which either holds the dust filter or the absorption filter. When the frame lower part holds the absorption filter, a frame upper part which holds the dust filter is releasably arranged upstream of the frame lower filter.

  • Patent number: 5221231
    Abstract: A motor vehicle heating/air-conditioning system of a motor vehicle has a water-removal device arranged in the fresh-air inlet duct, rising from the duct base and comprising a coarse-mesh lattice and a fine-mesh lattice resting against the latter. The water removed is carried away downwardly on the webs of the coarse-mesh lattice to the duct base which forms a water collection point with water drainage. In order to combine a favorable water-removal function with a good air-guidance function, the coarse-mesh lattice facing the incident air represents an air guide with predetermined throughflow and is pleated in a corrugated shape. A channel spanned by the fine-mesh lattice arranged in at least some areas is in each case formed between two upwardly-directed corrugation troughs. The water-removal device is placed in the region of a duct widening provided by a set-back wall portion, such that the water-removal device ends at a distance from the set-back wall portion.

  • Patent number: 5162019
    Abstract: Air-permeable and water-permeable baffles in the form of a fine-meshed grill are mounted in front of the upwardly projecting side walls in a motor vehicle fresh-air intake duct in order to improve separation with an inlet grill retaining any coarse impurities and with at least one drainage aperture, located in the area of the lowest point of the fresh-air intake duct, for liquid separated out from the air current. The liquid making its way through the meshes of the grills flows, in the flow vacuum between baffle and side wall at the back of the baffle, downwards to the duct bottom and the drainage aperture.
