An air conditioner where, even if spaces to be air conditioned by the air conditioner have different temperatures, an error of determination of the amount of refrigerant can be reduced. The air conditioner (1) adjusts the temperature of spaces and has a refrigerant circuit (10) and a control section (8). The refrigerant circuit (10) is constructed by connecting a compressor (21), an outdoor heat exchanger (23), indoor expansion valves (41, 51), and indoor heat exchangers (42, 52). The control section (8) performs temperature control so that the spaces are at predetermined temperatures. Also, the control section (8) determines the amount of the refrigerant in the refrigerant circuit (10) based on at least either the refrigerant flowing in the refrigerant circuit (10) or operation state quantities of constituting devices. Before the control device (8) determines the amount of the refrigerant, it sets the temperatures of the spaces so that the temperatures satisfy predetermined temperature conditions. |
