Abstract
A vehicle air conditioning system includes an electric powered refrigerant compressing device, an evaporator, an electric heater, an air temperature determining component, a cabin interior temperature controlling component, an upper limit electric power setting component, and an electric power distribution controller. The evaporator receives refrigerant from the compressing device. The heater is downstream of the evaporator in an air passageway. The determining component determines a first air temperature upstream of the evaporator and a second air temperature between the evaporator and the heater. The controlling component sets a vehicle interior discharge air temperature at a position downstream of the heater to a target temperature. The power setting component sets an upper limit for power supplied to the compressing device and the heater. The power distribution controller distributes the upper limit electric power to the compressing device and the heater based on a ratio of upstream and downstream temperature differences.
