Air conditioner for vehicle










Image Number 14 for United States Patent #8047274.

An air conditioner for a vehicle includes a main heater for heating air in a vehicle compartment using coolant of an engine of the vehicle as a heat source, and an auxiliary heater for heating air in the vehicle compartment using a heat source other than exhaust heat of the engine. In the air conditioner, a requirement signal for requiring startup of the engine is output when a temperature of the coolant of the engine is determined to be lower than a threshold, and the threshold is adjusted based on an operating state of the auxiliary heater such that as an amount of heat generated by the auxiliary heater increases, the threshold decreases. Accordingly, as the heating capacity of the auxiliary heater is increased, the startup of the engine becomes more difficult.
