Abstract
If an exterior heat exchanger is sensed to be frosted while a heat pump device is operating in a first heating operation mode in which two interior heat exchangers are used, the operation modes are switched into a second heating operation mode in which one interior heat exchanger is used, and then switched into a defrosting operation mode.
