<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of appropriately determining the amount of a refrigerant without requiring much time even if a liquid refrigerant is accumulated in an accumulator when such determination is performed. <P>SOLUTION: The air conditioner 1 has a refrigerant circuit 10 with the accumulator, a shutoff mechanism 38, a refrigerant detecting mechanism 39, an operation controlling means, a refrigerant amount determining means, a means for determining liquid refrigerant accumulation, and a liquid refrigerant releasing means. In a cooling operation condition, the refrigerant detecting mechanism 39 detects the state quantity of the amount of the refrigerant present upstream of the shutoff mechanism 38. The operation controlling means performs liquid refrigerant storage control. The refrigerant amount determining means determines whether or not the amount of the refrigerant in the refrigerant circuit 10 is appropriate based on the state quantity of the amount of the refrigerant detected by the refrigerant detecting mechanism 39 in the liquid refrigerant storage control. The means for determining liquid refrigerant accumulation determines whether or not a liquid refrigerant is accumulated in the accumulator. When it is determined that the liquid refrigerant is accumulated in the accumulator, the liquid refrigerant releasing means releases the liquid refrigerant from the accumulator. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
