1. An air conditioning apparatus equipped with a refrigerant circuit configured with plural indoor units connected to an outdoor unit, the air conditioning apparatus comprising:

  • a capacity controlling part controlling an air conditioning capacity of the outdoor unit such that an evaporation temperature of refrigerant in the refrigerant circuit becomes a target evaporation temperature; and

    a target refrigerant temperature mode setting part setting a target refrigerant temperature mode to one ofa target refrigerant temperature changing mode that changes the target evaporation temperature, anda target refrigerant temperature fixing mode that fixes the target evaporation temperature,the target refrigerant temperature changing mode havinga first changing mode that changes the target evaporation temperature in such a way that room temperatures of air conditioned spaces targeted by the indoor units reach set temperatures that are target values of the room temperatures in an amount of time, anda second changing mode that changes the target evaporation temperature in such a way that the room temperatures reach the set temperatures in a longer amount of time than in the first changing mode, andthe first changing mode and the second changing mode being set by the target refrigerant temperature mode setting part.
