摘要： An air conditioner is provided which is capable of allowing an operator to know, during a refrigerant charging operation using a cylinder, that the refrigerant cylinder is emptied without using a scale or the like. An air conditioner (1) in which the refrigerant is charged using a cylinder (90) containing the refrigerant includes a refrigerant circuit (10), a charge port (P), a downstream temperature sensor (92), an outdoor side controller (37), and a display unit (9). The refrigerant circuit (10) is configured by the interconnection of a compressor (21), an outdoor side heat exchanger (23), an indoor side expansion valve (41, 51), and an indoor side heat exchanger (42, 52). The charge port (P) is a port for charging the refrigerant into the refrigerant circuit (10) from the cylinder (90). The downstream temperature sensor (92) is provided in the vicinity of the charge port (P) of the refrigerant circuit (10). The outdoor side controller (37) judges whether or not the cylinder (90) is emptied based on a change in at least one of a temperature detected by the downstream temperature sensor (92) or a superheating degree. The display unit (9) performs output when it is judged by the outdoor side controller (37) that the cylinder (90) is emptied.

摘要： In an air conditioner, unpleasant feeling that is resulted from an operating sound of a compressor when the operation frequency thereof is rising is suppressed. An outdoor control unit (20) includes a first control unit (22), a second control unit (23), and a switching unit (24), and controls the rotational speed of an outdoor fan (30). The outdoor fan (30) sends air to an outdoor heat exchanger (13) in order to encourage heat exchange at the outdoor heat exchanger (13). The first control unit (22) executes a first control for controlling the rotational speed of the outdoor fan (30) based on the operation frequency of the compressor (11). The second control unit (23) executes a second control for controlling the rotational speed of the outdoor fan (30) based on a parameter other than the operation frequency of the compressor (11). The switching unit (24) executes a switching control for switching between the first control and the second control according to a predetermined switching condition, when a cooling mode is being operated under a low outside air condition. The low outside air condition refers to a state that the outside air temperature is lower than a first temperature.

摘要： Power saving is implemented by cutting power to a compressor driver (31a) and a fan driver (31b) while operating power is kept supplied to a control substrate (307). After the power source to the control substrate (307) is turned on, power is supplied to the compressor driver (31a) and the fan driver (31b). Then, when it is determined that an indoor unit is in operation, the compressor driver (31a) and the fan driver (31b) are operated. Meanwhile, when it is determined that the indoor unit is not in operation, after the lapse of ten minutes or twenty minutes under a predetermined setting, the power to the compressor driver (31a) and the fan driver (31b) is cut. When the operation of the indoor unit is started again, power is supplied to the compressor driver (31a) and the fan driver (31b).

摘要： To provide an outdoor unit of an air conditioner that can quickly cause a compressor to start up, an air conditioner, and a compressor startup method in an outdoor unit of an air conditioner. An outdoor unit (2a to 2c) of an air conditioner (1) is disposed with plural constant capacity compressors (27a to 27c, 28a to 28c), a variable capacity compressor (22a to 22c) and a controller (6a to 6c). The plural constant capacity compressors (27a to 27c, 28a to 28c) compress refrigerant in a predetermined capacity. The variable capacity compressor (22a to 22c) is capable of having its capacity changed and compressing refrigerant. The controller (6a to 6c) sequentially causes the plural constant capacity compressors (27a to 27c, 28a to 28c) to start up and thereafter regulates the operating frequency of the variable capacity compressor (22a to 22c).
