Abstract
An air conditioning system for a vehicle includes a compressor driven by a first drive source or a second drive source, or a combination thereof, and an evaporator operationally connected to the compressor via a refrigerant circuit. The system also includes a blower for dispensing air into an interior of the vehicle via the evaporator. The blower is driven by the first drive source or the second drive source, or a combination thereof. Moreover, the system includes a controller for controlling the first drive source and the second drive source. Specifically, when a temperature of air dispensed from the evaporator is greater than a predetermined temperature and a speed of the vehicle is greater than a predetermined speed, the first drive source drives the compressor and the blower. Moreover, when the temperature of air dispensed from the evaporator is greater than the predetermined temperature, the speed of the vehicle is less than the predetermined speed, and a voltage of a power source of the second drive source is less than or equal to a predetermined voltage, the compressor is inactive and the second drive source drives the blower.
