Abstract
A air conditioning control device is configured to estimate whether or not the temperature of refrigerant on a high-pressure side in a heat pump device is equal to or lower than a predetermined low temperature and to switch a flow path switching device to an air-heating start-up mode when it is estimated that the temperature of refrigerant on the high-pressure side in the heat pump device is equal to or lower than the predetermined low temperature and switch the flow path switching device to a normal air-heating mode when it is estimated that the temperature of refrigerant on the high-pressure side in the heat pump device is higher than the predetermined low temperature.
