PROBLEM TO BE SOLVED: To accurately estimate a heat load to enhance cabin temperature control capability. SOLUTION: The air conditioner has a first surface temperature sensor 70h for detecting the surface temperature of a portion where temperature varies by the influence of the outside surface temperature of a vehicle and a second surface temperature sensor 70k for detecting the surface temperature in a portion where temperature varies by the influence of solar radiation entering the cabin, and target blow-out air temperature is calculated by inputting surface temperature signals of these sensors. Thereby, entering heat (a heat load) caused by the difference between inner temperature and a cabin inside surface temperature can directly be estimated compared with the conventional device, and the heat load can accurately be estimated. The entering heat (a heat load) caused by entering of solar radiation can be estimated from temperature of a portion where temperature varies by the influence of the solar radiation, and the heat load can accurately be estimated.
