ABSTRACT:
An air conditioner is provided that 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 in which the refrigerant is charged using a cylinder containing the refrigerant includes a refrigerant circuit, a charge port, a downstream temperature sensor, an outdoor side controller, and a display unit. The refrigerant circuit is configured by the interconnection of a compressor, an outdoor side heat exchanger, an indoor side expansion valve, and an indoor side heat exchanger. The charge port is a port for charging the refrigerant into the refrigerant circuit from the cylinder. The downstream temperature sensor is provided in the vicinity of the charge port of the refrigerant circuit. The outdoor side controller judges whether or not the cylinder is emptied based on a change in at least one of a temperature detected by the downstream temperature sensor or a superheating degree. The display unit performs output when it is judged by the outdoor side controller that the cylinder is emptied.
