Patent Images
1. An air-conditioner for a vehicle comprising:
- a heat pump cycle having an outdoor heat exchanger that condenses high-pressure refrigerant by exchanging heat with outside air;
a frost state calculator that calculates a degree of frost formed in the outdoor heat exchanger;
an output portion that outputs information of the frost formed in the outdoor heat exchanger; and
a controller that instructs a defrosting operation for melting the frost adhering to the outdoor heat exchanger by controlling a component of the heat pump cycle, whereinthe controller controls the output portion to output the degree of frost calculated by the frost state calculator as a frost information, when the defrosting operation is not performed, andthe controller controls the output portion to output a defrosting information representing that the defrosting operation is being performed, when the defrosting operation is performed.
