PROBLEM TO BE SOLVED: To provide a vehicle air conditioning apparatus that is made to properly stop the operation of a cooling fan attached to a capacitor in a simple structure.SOLUTION: An air conditioning apparatus includes, between a capacitor 20 and an evaporator 50, a pressure switch 1 for a fan that performs on/off operation according to the pressure of the refrigerant, and makes a cooling fan 21 operate at on time and makes the cooling fan 21 stop the operation at off time. The capacitor 20 is a side capacitor, and when the pressure of the refrigerant is below the fan stop pressure, the pressure switch 1 for the fan turns off. The fan stop pressure is set beforehand as a threshold of the pressure of the refrigerant where the refrigerant is liquefied enough in the capacitor 20 even if the cooling fan 210 is not operated. |
