An air conditioning apparatus which includes at least a compression mechanism, an indoor heat exchanger, an indoor fan, an expansion mechanism, an outdoor heat exchanger and a control part for performing startup fan control; wherein the air conditioning apparatus is characterized by further comprising: a refrigerant-pressure-perceiving part for perceiving the pressure of refrigerant sent from the compression mechanism to the indoor heat exchanger; and wherein the control part is configured so that the indoor fan remains stopped until the compression mechanism goes from being at rest to starting up and the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds a predetermined high-pressure threshold (Ph); the indoor fan is driven when the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds the predetermined high-pressure threshold (Ph); and the following actions are repeated: an action of reducing or stopping the air volume of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part decreases to or falls below a predetermined low-pressure threshold (Pl) which is a lower value than the predetermined high-pressure threshold; and an action of increasing the air volume or initiating the driving of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds a predetermined pressure threshold (Pm) which is a higher value than the predetermined low-pressure threshold. a refrigerant-pressure-perceiving part for perceiving the pressure of refrigerant sent from the compression mechanism to the indoor heat exchanger; and wherein the control part is configured so that the indoor fan remains stopped until the compression mechanism goes from being at rest to starting up and the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds a predetermined high-pressure threshold (Ph); the indoor fan is driven when the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds the predetermined high-pressure threshold (Ph); and the following actions are repeated: an action of reducing or stopping the air volume of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part decreases to or falls below a predetermined low-pressure threshold (Pl) which is a lower value than the predetermined high-pressure threshold; and an action of increasing the air volume or initiating the driving of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds a predetermined pressure threshold (Pm) which is a higher value than the predetermined low-pressure threshold. an action of reducing or stopping the air volume of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part decreases to or falls below a predetermined low-pressure threshold (Pl) which is a lower value than the predetermined high-pressure threshold; and an action of increasing the air volume or initiating the driving of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds a predetermined pressure threshold (Pm) which is a higher value than the predetermined low-pressure threshold.
