Abstract: A vehicle control system into which battery temperature management and air conditioning are integrated includes a battery temperature management unit setting a temperature of a battery module provided in a vehicle to be in a predetermined range, by circulating a coolant, an air conditioning unit operating as an air conditioner or a heat pump according to a circulation direction of a refrigerant, a heat exchange unit causing the coolant and the refrigerant to exchange heat with each other, and a controller performing control so that the battery temperature management unit operates, that the air conditioning unit operates as the air conditioner or the heat pump according to a request for cooling of air inside of the vehicle or a request for heating of the air inside of the vehicle, and that the heat exchange unit selectively absorbs heat of the refrigerant.

Abstract: An air conditioner system for mobility is provided. The air conditioner system is configured to secure the air conditioning performance in cooling and heating conditioning and to prevent a battery from being deteriorated as the battery is prevented from being overcharged while the air conditioner system is driven when the battery is charged by the regenerative breaking while the charge amount of the battery is already high.

Abstract: An air conditioning apparatus for a vehicle includes an air conditioner unit disposed in an air conditioning room of a vehicle and configured in such a manner that ambient air, introduced into the air conditioning room from an outside of the vehicle, is suctioned and blown to an interior of the vehicle by a blower; a damper installed in an opening on an introduction side of the air conditioner unit to selectively allow introduction of one of indoor air flowing from the interior and ambient air; and an internal exhaust grill installed in the interior to fluidly communicate with a space defined by the air conditioner unit and an internal side surface of the air conditioning room, wherein the indoor air in the interior may be discharged to an outside of the vehicle through the internal exhaust grill and the air conditioning room.

Abstract: A bus heating system and a method of controlling the same, is configured for controlling a water-heating-type main heater unit and a heat-pump-type auxiliary heater unit in conjunction with each other for heating an interior of a bus, improving the efficiency of operation of the main heater unit while reducing the number of switch operations. The bus heating system includes a water-heating-type main heater unit configured to heat an internal bottom area of the bus, a heat-pump-type auxiliary heater unit configured to heat an internal roof area of the bus, and a controller configured to control operations of the main heater unit and the auxiliary heater unit in conjunction with each other based on a set target internal temperature (Ttarget), a measured outside air temperature (Toutside), a measured internal temperature (Troom), and a main-heater-unit refrigerant temperature (Trefrigerants).

Abstract: An air-conditioner casing for an air conditioner mounted on a ceiling of a bus are provided. The air-conditioner casing includes: a pair of bases having first and second bases which are installed to be spaced apart from and opposite to each other; and one or more shrouds coupled in a space between the first and second bases, in which the number of shrouds to be connected and installed in the casing may be determined based on a capacity of an air conditioner.

Abstract: A multi-zone air conditioner system for large vehicles may include an air conditioning device configured to partition an internal of a vehicle into a plurality of zones to independently cool each zone, a detecting device configured to include a room temperature detector for detecting a room temperature of each zone and a photo detector for detecting an amount of solar radiation, an input device configured to switch an operating state of the air conditioning device to an automatic mode or a manual mode, and a control device configured to generate a control signal for operating the air conditioning device based on a signal transmitted from the detecting device and the input device.
