摘要： An air-conditioning apparatus detects refrigerant leak with high-accuracy even in a state in which an excessive liquid refrigerant is stored in an accumulator. The air-conditioning apparatus determines that leakage of refrigerant has occurred from a refrigerant circuit in an operating state in which an excessive liquid refrigerant is stored in an accumulator, after a part of the excessive liquid refrigerant stored in the accumulator is moved and stored into a condenser, with the excessive liquid refrigerant remaining in the accumulator as a reference amount, when the excessive liquid refrigerant is less than the reference amount.

摘要翻译： 即使在储液器中储存有过量的液体制冷剂的状态下，空气调节装置也能够高精度地检测制冷剂的泄漏。 在存储在蓄压器中的一部分过剩的液体制冷剂移动并储存在储存器中之后，空气调节装置判定在制冷剂回路中发生过剩的液体制冷剂储存在储液器中的运行状态下的制冷剂泄漏 冷凝器中剩余的过量的液体制冷剂作为基准量，当过量的液体制冷剂小于基准量时。
