摘要:
A door structure for an air conditioner of a vehicle includes an indoor/outdoor air door having a dome shape. An outdoor air door has a plate shape and adjusts the amount of outdoor air introduced into the vehicle. First and second counter-flow preventing ribs are disposed vertically between the dome shaped indoor/outdoor air door and the plate shaped outdoor air door. The first counter-flow preventing rib is mounted to a first hinge which is connected to one end of the plate shaped outdoor air door. The second counter-flow preventing rib is mounted to be close to another end of the plate shaped outdoor air door. An air conditioning filter is disposed below the dome shaped indoor/outdoor air door, the plate shaped outdoor air door, and the first and second counter-flow preventing ribs and filters the introduced indoor air or outdoor air.

A heat pump system for a vehicle delays the change of the direction of a directional valve for a given period of time and then conducts the change of the direction of the directional valve, upon receiving the mode change signal between an air conditioner mode and a heat pump mode, thus preventing the generation of the noise and vibration caused by the differential pressure of a refrigerant.
摘要:
A heat pump system for a vehicle which uses an evaporator of an air-conditioning case for common use in an air-conditioning mode and in a heat pump mode for cooling and heating so as to reduce weight and manufacturing costs. The heat pump system can be applied without any change in structure of the air-conditioning case, and can be operated even at low temperature without any influence of outdoor temperature because the heat pump system uses waste heat of an engine so as to enhance fuel efficiency and increase heating performance and efficiency.

A system and a method for mixing cabin and outside air of a vehicle air-conditioner may include a housing having cabin and outside air inlets for ventilating the cabin and outside air, a first door part to selectively cover at least a portion of the cabin air inlet and/or a portion of the outside air inlet to adjust an open value of each of the inlets, a second door part to selectively cover the remaining portion of the outside air inlet to adjust the open value of the outside air inlet, a cam part rotatable in the housing and formed with first and second slots to which the first and second door parts are slidably coupled such that rotation angle of the first or the second door part is varied according to rotation of the cam part, and a controlling unit controlling the rotation of the cam part.

A method of controlling a fuel cell includes collecting, by a control unit, environmental information and state information of a fuel cell stack; determining, by the control unit, a motor output offset value from the collected environmental information and the collected state information of the fuel cell stack; correcting, by the control unit, a default critical output corresponding to a current vehicle operating state based on the determined motor output offset value; determining, by the control unit, the stop or the restart of the fuel cell by comparing a motor output demand determined from current vehicle operating information with the corrected critical output; and controlling, by the control unit, an operating state of the fuel cell to become a state of the determined stop or restart.
摘要:
A fuel cell system includes an air supply unit for supplying air containing oxygen to a fuel cell stack. A humidifier humidifies the supplied air. An air supply line is connected between a cathode inlet of the fuel cell stack and the humidifier to supply the humidified air to the fuel cell stack. A cathode-side exhaust line is connected between a cathode outlet of the fuel cell stack and the humidifier to supply a cathode exhaust gas discharged from a cathode of the fuel cell stack to the humidifier for humidification in the humidifier. A unified valve module includes a bypass line connected between the air supply line and the cathode-side exhaust line and an outward discharge port discharging the cathode exhaust gas to outside, and controls a gas flow between the humidifier and the fuel cell stack and between the bypass line and the outward discharge port.
