    摘要: A vehicle air conditioning apparatus is provided to prevent a frost from being formed on a heat exchanger under the condition that the outdoor temperature is low. During a heating and dehumidifying operation, the third solenoid valve 25c is closed when outdoor temperature Tam is predetermined temperature T1 or lower, or when temperature Thex of the refrigerant flowing out of the outdoor heat exchanger 22 is a predetermined temperature T2 or lower and temperature Te detected by the cooled air temperature sensor 44 is temperature Tet-β or lower. By this means, during the heating and dehumidifying operation, when a frost is likely to be formed on the heat exchanger 14, it is possible to prevent the refrigerant from flowing into the heat exchanger 14, and to prevent a frost from being formed on the heat exchanger 14.
