Document Type and Number:
Japanese Patent JP2016049914
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle air conditioner for an electric vehicle, capable of managing defrosting operation time according to the power state of the vehicle and setting a balance between the recovery of a sufficient heat absorbing ability of an outdoor heat exchanger and the securing of a traveling distance at the time of restarting the vehicle.SOLUTION: During the defrosting operation of removing frost stuck to an outdoor heat exchanger 24, a high-temperature and high-pressure refrigerant compressed by a compressor 21 is introduced to the outdoor heat exchanger 24. Control means stops, in the case of executing a defrosting operation at the time of power supply from the outside of the vehicle, the defrosting operation when a temperature near the outdoor heat exchanger 24 rises equal to or more than a first prescribed temperature, and stops, in the case of executing a defrosting operation at the time of no power supply from the outside of the vehicle, the defrosting operation when the temperature near the outdoor heat exchanger 24 rises equal to or more than a second prescribed temperature lower than the first prescribed temperature.SELECTED DRAWING: Figure 1
