Abstract: The passenger compartment air-conditioning apparatus has a second heat exchanger disposed adjacent to and in front of a first heat exchanger for cooling a cooling liquid of a battery. When the temperature of the battery is increased at the time the battery is charged in a quick charge mode, a compressor of the passenger compartment air-conditioning apparatus is actuated by a coaction of a battery ECU and an air-conditioning ECU to supply a refrigerant to the second heat exchanger. A fan is rotated to cool external air with the second heat exchanger. The cooled external air is introduced into the first heat exchanger, which cools the cooling liquid of the battery.

Abstract: A control apparatus controls a vehicular air-conditioning system to control a fuel-combustion heater for producing combustion heat to heat a heating medium in a heating medium circuit which heats air flowing through a duct having air outlets openable into a passenger compartment, through heat exchange between the heating medium and the air with a heat exchanger disposed in the duct. The control apparatus has a shutdown controller for temporarily shutting down the fuel-combustion heater and an extinguishing controller for extinguishing the fuel-combustion heater based on a signal from the shutdown controller. The shutdown controller includes a shutdown signal entering unit for entering a shutdown signal to temporarily shut down the fuel-combustion heater and a shutdown signal canceler for canceling the shutdown signal in response to a canceling signal entered to cancel the shutdown of the fuel-combustion heater within a predetermined period of time after the shutdown signal has been entered.

Abstract: Disclosed is a remaining fuel alarm for a vehicular fuel-combustion heater, comprising a thermistor for detecting whether or not a predetermined amount of fuel is stored in a fuel tank, a remaining fuel alarm lamp for displaying the fact that a remaining amount of fuel in the fuel tank is not more than a predetermined amount, and a relay for enabling the remaining fuel alarm lamp to operate only when a signal to request operation of a fuel-combustion heater is inputted.

Abstract: A vehicular defroster control system comprising a single defroster selector switch for alternatively operating the air-conditioning defroster only or both the air-conditioning defroster and the electric heat-operated defroster, an environmental condition input unit for inputting environmental conditions including at least an ambient air temperature and a sunlight intensity, and an operation control means for judging whether or not the inputted ambient air temperature and the sunlight intensity are lower than previously set predetermined values, and operating the electric heat-operated defroster only when it is judged that both of the inputted ambient air temperature and the sunlight intensity are lower than the predetermined values.

Abstract: Disclosed is a heat exchange system for an electric vehicle, comprising a heating hot water circuit for heating, with hot water, air to a predetermined temperature before being discharged into a passenger's compartment, and a cooling circuit for cooling, with cooling water, a driving motor and a battery for supplying electric energy to the driving motor, wherein water supplement and drain operations are performed by using a single reserve tank for the hot water circuit and the cooling circuit.

Abstract: Disclosed is a system for controlling a vehicular fuel-combustion heater, comprising an environmental condition input unit for inputting environmental conditions including an ambient air temperature; an operation start-judging unit for judging whether or not the inputted ambient air temperature is lower than a previously set first reference temperature, and starting operation of the fuel-combustion heater when the inputted ambient air temperature is lower than the first reference temperature; and a reference temperature-changing unit for setting, for the first reference temperature, a second reference temperature which is lower than the first reference temperature when the fuel-combustion heater is operated for the second time or later.
