Claim 1:
2. The vehicle air conditioning device according to claim 1, comprising:
a first map that represents a relationship between the high pressure side pressure detected by the high pressure side pressure sensor and an outside air temperature;
a second map for converting the heater core inlet refrigerant temperature detected by the heater core inlet refrigerant temperature sensor to a first correction outside air temperature; and
a third map for converting the amount of solar radiation detected by the solar radiation sensor to a second correction outside air temperature,
wherein the estimated outside air temperature is calculated based on the outside air temperature calculated using the first map, the first correction outside air temperature calculated using the second map, and the second correction outside air temperature calculated using the third map.
