摘要： 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.

摘要： An air conditioner is provided with a refrigerant circuit, refrigerant stagnation judging means, and an operation controller. The refrigerant circuit is a circuit that includes a heat source unit, a refrigerant communication pipe, an expansion mechanism, and a utilization unit. A heat source unit and a utilization unit are connected to the refrigerant fluid communication pipes. The heat source unit has a compression mechanism and a heat source side heat exchanger. The refrigerant stagnation judging means can judge whether the refrigerant has stagnated inside the compression mechanism. The operation controller performs a refrigerant de-stagnation operation for eliminating stagnation of the refrigerant in the case that the refrigerant stagnation judging means has judged in advance that the refrigerant inside the compression mechanism has stagnated when a refrigerant quantity judging operation is carried out for judging the refrigerant quantity inside the refrigerant circuit.

摘要： An air conditioner includes a refrigerant circuit, an operation controlling section, a stability judging section, a refrigerant quantity judging section, and a condition changing section. The operation controlling section is capable of performing a refrigerant quantity judging operation to control constituent equipment to reach a predetermined target control value. The stability judging section judges whether or not the refrigerant quantity judging operation has stabilized. The refrigerant quantity judging section judges the adequacy of the refrigerant quantity in the refrigerant circuit by using an operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit when it is judged that the refrigerant quantity judging operation has stabilized. The condition changing section changes the target control value in the refrigerant quantity judging operation when it is judged that the refrigerant quantity judging operation has not stabilized.

摘要： An error in judgment due to the difference in the temperature of the refrigerant at an outlet of a condenser is reduced when judging the adequacy of the refrigerant quantity. An air conditioner (1) includes a refrigerant circuit (10), operation controlling means, and refrigerant quantity judging means. The refrigerant circuit (10) is configured by the interconnection of a compressor (21), an outdoor heat exchanger (23), a subcooler (25), an indoor expansion valve (41, 51), and an indoor heat exchanger (42, 52). The operation controlling means can perform a refrigerant quantity judging operation in which performance of the subcooler (25) is controlled such that the temperature of the refrigerant sent from the subcooler (25) to the indoor expansion valve (41, 51) becomes constant. The refrigerant quantity judging means judges the adequacy of the refrigerant quantity in the refrigerant circuit (10) based on an operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit (10) in the refrigerant quantity judging operation.

摘要： An instantaneous current and instantaneous voltage of a three-phase coil of a brushless DC motor are detected, and the internal condition of a compressor is predicted from these detection values. The prediction about the internal condition of the compressor is made in such a way that motor driving torque which is a parameter of a motor model is identified and poor lubrication, liquid compression or the like is predicted from this identified motor driving torque. This enables it to make, in real time, a failure forecast, failure diagnosis etc. on the compressor.

摘要： A refrigerant circuit (11) includes an oil separator (60) configured to separate oil from high pressure refrigerant, and an oil feed circuit (70) configured to feed the oil separated in the oil separator (60) to a compression mechanism (20) so as to cool the refrigerant in the course of a compression phase of the compression mechanism (20). The oil feed circuit (70) includes a recovery mechanism (40) configured to recover energy of the oil separated in the oil separator (60). In the compression mechanism (20), the refrigerant is cooled by the oil, thereby reducing power of the compression mechanism (20).
