Abstract
Vehicle air conditioning device of a heat pump system in which comfort is compatible with decrease of power consumption. The vehicle air conditioning device includes a heating medium circulating circuitto heat air to be supplied from an air flow passageto a vehicle interior, and in a heating mode, a controller has an energy saving prior mode in which the controller operates a compressorat a maximum number of revolution and complements a shortage of a heating capability by a radiatorwith heating by a heating medium-air heat exchangerof the heating medium circulating circuit, and a comfort prior mode in which the controller limits a number of revolution of the compressorand complements the shortage of the heating capability by the radiatorwith the heating by the heating medium-air heat exchangerof the heating medium circulating circuit
