    • This invention makes it possible to charge a refrigeration apparatus with the amount of refrigerant that the refrigeration apparatus requires at the time of onsite installation. As a result, the optimum refrigerant charging amount can always be obtained. The refrigeration apparatus is provided with a refrigeration cycle (A) in which an outdoor unit (X) equipped with a compressor (1), a condenser (2), and a receiver (3) and an indoor unit (Y) equipped with an expansion valve (4) and an evaporator (5) are connected together by a liquid pipe (8) and a gas pipe (9). The refrigeration cycle (A) is charged with refrigerant while a refrigerant charging operation state is created in which the liquid pipe (8) connecting the outdoor unit (X) to the indoor unit (Y) is filled with liquid refrigerant having a prescribed density. Refrigerant charging is ended at the point in time when, during said refrigerant charging operation, it is detected that the level (L) of the liquid inside the receiver (3) has reached a prescribed level (L0).
    • 本发明使得能够向制冷设备充入在现场安装时制冷设备需要的制冷剂的量。 结果,总是可以获得最佳的制冷剂充注量。 该制冷装置具备:具备具备压缩机(1),冷凝器(2)和接收器(3)的室外机组(X)和配备有制冷剂回路的室内机组(Y)的制冷循环(A) 膨胀阀(4)和蒸发器(5)通过液体管道(8)和气体管道(9)连接在一起。 在制冷剂填充运转状态下,制冷剂循环(A)被充入制冷剂填充运行状态,在制冷剂填充运行状态下,连接室外单元(X)与室内单元(Y)的液体管道(8)充满具有规定密度的液体制冷剂。 在所述制冷剂填充操作期间,当检测到接收器(3)内的液体的液位(L)已经达到规定的液位(L0)时,制冷剂充注结束。
