ABSTRACT:
An air conditioner includes a refrigerant circuit, a refrigerant quantity calculating section, and a refrigerant quantity judging section. The refrigerant circuit includes a compressor, an outdoor heat exchanger, an indoor expansion valve, and an indoor heat exchanger interconnected together. The refrigerant quantity calculating section calculates the refrigerant quantity in the refrigerant circuit taking into account a dissolved refrigerant quantity that is the quantity of refrigerant dissolved in the refrigerating machine oil in the compressor, based on an operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit. The refrigerant quantity judging section judges the adequacy of the refrigerant quantity in the refrigerant circuit based on the refrigerant quantity calculated by the refrigerant quantity calculating section. In addition, the refrigerant quantity calculating section calculates the dissolved refrigerant quantity based on operation state quantities that include at least the ambient temperature outside the compressor.
