    摘要: In a multi-type air conditioner, the adequacy of the refrigerant quantity charged in the air conditioner can be accurately determined, even when the refrigerant quantity charged on site is inconsistent, or even when a reference value of the operation state quantity, which is used for determining the adequacy of the refrigerant quantity, fluctuates depending on the pipe length of the refrigerant communication pipe, combination of utilization units, and the difference in the installation height among each unit. In an air conditioner (1) including a refrigerant circuit (10) configured by the interconnection of a heat source unit (2) and utilization units (4, 5) via refrigerant communication pipes (6, 7), a refrigerant quantity determining system determines the adequacy of the refrigerant quantity and includes a state quantity storing means and a refrigerant quantity determining means. The state quantity storing means stores the operation state quantity of constituent equipment or the refrigerant flowing in the refrigerant circuit (10) in which refrigerant is charged up to an initial refrigerant quantity by on-site refrigerant charging. The refrigerant quantity determining means compares the operation state quantity during test operation as a reference value with a current value of the operation state quantity, and thereby determines the adequacy of the refrigerant quantity.

    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.
