<p>An air conditioner is provided in which the labor of inputting information on a utilization unit before operating a separate type air conditioner is reduced, and at the same time, the adequacy of the refrigerant quantity in a refrigerant circuit can be judged with high accuracy. An air conditioner (1) includes a refrigerant circuit (10) configured by the interconnection of a heat source unit (2) and a utilization unit (4, 5), a transmission line (8a) that exchanges a signal between the heat source unit (2) and the utilization unit (4, 5), information obtaining means, operation controlling means capable of performing a refrigerant quantity judging operation, refrigerant quantity judging means, and condition setting means. The information obtaining means obtains information on the utilization unit (4, 5) connected to the heat source unit (2) via the transmission line (8a). The refrigerant quantity judging means judges the adequacy of the refrigerant quantity in the refrigerant circuit (10) by using the operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit (10) in the refrigerant quantity judging operation. The condition setting means sets a condition for the refrigerant quantity judging operation according to the information on the utilization unit (4, 5) obtained by the information obtaining means.</p> |
