Abstract
A vehicle air-conditioning apparatus is provided which is capable of expanding an effective range of a dehumidifying and heating mode to achieve comfortable vehicle interior air conditioning. A control device (controller) executes a dehumidifying and heating mode to let a refrigerant discharged from a compressorradiate heat in a radiator, let a part of the refrigerant flow from a bypass circuit (refrigerant pipeF) to an indoor expansion valve, and let the residual refrigerant flow through an outdoor expansion valve. In the dehumidifying and heating mode, the control device has a state of controlling the operation of the compressor, based on a heat absorber temperature Te and executes a radiator temperature priority mode which enlarges a capability of the compressor when heat radiation in the radiator is insufficient.
