An air conditioning apparatus comprising: a refrigerant circuit that is configured as a result of a compressor, a condenser, a first expansion valve, a second expansion valve, and an evaporator being sequentially connected; a blower fan operable to supply air as a heat source to the condenser; and a controller operable to control the air flow rate of the blower fan and the opening degree of the first expansion valve such that high pressure in a refrigeration cycle operation of the refrigerant circuit reaches a target high pressure; the controller operable: to control (S6,S8,S9) the opening degree of the first expansion valve such that a high pressure in a refrigeration cycle operation of the refrigerant circuit reaches a target high pressure in a state where air flow rate control of the blower fan has been performed such that the air flow rate of the blower fan reaches a prescribed air flow rate; and to control the air flow rate of the blower fan to decrease the air flow rate when the high pressure is not larger than a lower limit value of the target high pressure and the opening degree of the first expansion valve (EV 1) is smaller than a minimum opening degree (S 19) and to increase the air flow rate when the high pressure is larger than an upper limit value of the target high pressure and the opening degree of the first expansion valve is larger than a maximum opening degree (S 15). a refrigerant circuit that is configured as a result of a compressor, a condenser, a first expansion valve, a second expansion valve, and an evaporator being sequentially connected; a blower fan operable to supply air as a heat source to the condenser; and a controller operable to control the air flow rate of the blower fan and the opening degree of the first expansion valve such that high pressure in a refrigeration cycle operation of the refrigerant circuit reaches a target high pressure; the controller operable: to control (S6,S8,S9) the opening degree of the first expansion valve such that a high pressure in a refrigeration cycle operation of the refrigerant circuit reaches a target high pressure in a state where air flow rate control of the blower fan has been performed such that the air flow rate of the blower fan reaches a prescribed air flow rate; and to control the air flow rate of the blower fan to decrease the air flow rate when the high pressure is not larger than a lower limit value of the target high pressure and the opening degree of the first expansion valve (EV 1) is smaller than a minimum opening degree (S 19) and to increase the air flow rate when the high pressure is larger than an upper limit value of the target high pressure and the opening degree of the first expansion valve is larger than a maximum opening degree (S 15). to control (S6,S8,S9) the opening degree of the first expansion valve such that a high pressure in a refrigeration cycle operation of the refrigerant circuit reaches a target high pressure in a state where air flow rate control of the blower fan has been performed such that the air flow rate of the blower fan reaches a prescribed air flow rate; and to control the air flow rate of the blower fan to decrease the air flow rate when the high pressure is not larger than a lower limit value of the target high pressure and the opening degree of the first expansion valve (EV 1) is smaller than a minimum opening degree (S 19) and to increase the air flow rate when the high pressure is larger than an upper limit value of the target high pressure and the opening degree of the first expansion valve is larger than a maximum opening degree (S 15).
