32. A vehicle air conditioning apparatus comprising:

a first pump and a second pump that take in and discharge a heat medium;

a compressor that takes in and discharges a refrigerant;

a condenser that condenses the refrigerant and heats the heat medium by exchanging heat between the refrigerant discharged from the compressor and the heat medium circulated by the second pump;

a decompression unit that decompresses and expands the refrigerant flowing from the condenser;

an evaporator that evaporates the refrigerant and cools the heat medium by exchanging heat between the refrigerant decompressed and expanded by the decompression unit and the heat medium circulated by the first pump;

an air-cooling heat exchanger that cools blast air into a vehicle interior by exchanging sensible heat between the heat medium cooled in the evaporator and the blast air;

an air-heating heat exchanger that heats the blast air by exchanging sensible heat between the heat medium heated in the condenser and the blast air;

a heat medium-to-outside air heat exchanger that exchanges sensible heat between the heat medium heated in the condenser and outside air such that the heat medium radiates heat to the outside air,

a refrigerant flow rate adjustment unit that adjusts the flow rate of the refrigerant discharged from the compressor in such a way that a temperature related to a temperature of the blast air cooled in the air-cooling heat exchanger approaches a first target temperature;

a heat exchanger adjustment unit that adjusts a flow rate of at least one of the heat medium and the outside air flowing through the heat medium-to-outside air heat exchanger;

an air-volume ratio adjustment units that adjusts an air volume ratio between a volume of blast air, which has been cooled in the air-cooling heat exchanger and passes through the air-heating heat exchanger, and a volume of blast air, which has been cooled in the air-cooling heat exchanger and does not pass through the air-heating heat exchanger, in such a way that a temperature related to a temperature of the blast air, which has been adjusted in at least one heat exchanger of the air-cooling heat exchanger and the air-heating heat exchanger and which is blown out into the vehicle interior, approaches a second target temperature; and

a heat exchanger adjustment unit that adjusts the flow rate of at least one of the heat medium and the outside air flowing through the heat medium-to-outside air heat exchanger,

wherein when it is determined that a target blow-out air temperature is higher than the temperature of the blast air flowing into the air-cooling heat exchanger, the heat exchanger adjustment unit adjusts the flow rate of at least one of the heat medium and the outside air flowing through the heat medium-to-outside air heat exchanger in such a way that the temperature related to the temperature of the blast air, which has been adjusted in at least one of the air-cooling heat exchanger and the air-heating heat exchanger and which is blown out into the vehicle interior, approaches the second target temperature.
