Abstract
A vehicle air-conditioning system limits electric power used by an electric motor for a compressor in a prescribed fashion that quickly removes fog from the windows when a defroster mode is selected. When the defroster mode is selected, the limit on the electric power used by the electric motor is lifted, and the number of revolutions of the compressor is set to a high level to raise the dehumidifying and cooling capability to quickly remove moisture from the windows.
Claims18
A vehicle air-conditioning system comprising:
- a compressor for compressing a refrigerant and discharging the compressed refrigerant;
- an electric motor for driving said compressor;
- and
- a heat exchanger for cooling air blown into a vehicle compartment by said refrigerant, electric power used by said electric motor being limited in a prescribed condition, wherein
- the limit on the electric power used by the electric motor is lifted when a defogging blowing mode to blow said air to glass windows is selected.
A vehicle air-conditioning system comprising:
- a compressor for compressing a refrigerant and discharging the compressed refrigerant;
- an electric motor for driving said compressor, said electric motor driven by a battery;
- and
- a heat exchanger for cooling air using said refrigerant, said air blown into a vehicle compartment,
- wherein the electric power used by said electric motor for said compressor is not limited when a defogging blowing mode is selected to blow air to vehicular glass windows.
A vehicle air-conditioning system comprising:
- a compressor for compressing a refrigerant and discharging the compressed refrigerant;
- an electric motor for driving said compressor;
- and
- a heat exchanger for cooling air blown into a compartment of a vehicle by said refrigerant,
- wherein electric power used by said electric motor is limited in a prescribed condition, wherein the electric power used by said electric motor is greater when an instruction of defogging vehicle glass windows is issued in said prescribed condition than that when there is no such defogging instruction.
