To precisely determine whether a refrigerant amount in an air conditioner is appropriate in any environmental conditions and installation conditions in accordance with a variation of air conditioner equipment system configuration, and equipment-installation-based piping length, piping diameter, level difference, number of connected indoor units and indoor unit capacity.
For refrigerant amount regulation, a flow regulating means 32 is disposed in the position of a passage to a refrigerant circuit from a refrigerant cylinder 31 filled with a recharge of refrigerant to an air conditioning refrigeration cycle apparatus. At refrigerant amount regulation, an operational state quantity varying with refrigerant amount is detected, and when the operation state quantity approaches a reference value stored in a storage means, the flow regulating means reduces the rate of refrigerant filling from the refrigerant cylinder to the refrigeration cycle apparatus.
