ABSTRACT:
An air conditioner that adjusts the temperature in a target space includes a refrigerant circuit and a controller. The refrigerant circuit is configured by the interconnection of a compressor, an outdoor heat exchanger, indoor expansion valves, and indoor heat exchangers. The controller adjusts the temperature such that predetermined temperature is reached in a target space. In addition, the controller judges the refrigerant quantity in the refrigerant circuit based on at least one value of operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit. The controller achieves a state in which the target space temperature satisfies a predetermined temperature condition.
