ABSTRACT:
The present invention allows an optimal quantity of refrigerant to be quickly and easily charged into the refrigeration device. In a refrigeration device that includes a refrigerant cycle circuit (A) connecting an outdoor unit (X) and indoor units (Y) via refrigerant lines (6), (7), a refrigerant charging device (10) that charges refrigerant to the refrigerant cycle circuit (A) in the cooling operational state is detachably connected to the liquid side refrigerant line (6) (the high pressure liquid line during cooling operations) that links the outdoor unit (X) with the indoor units (Y). In this way, when the refrigerant charging device (10) and the liquid line refrigerant line (6) are linked together and the refrigerant cycle circuit (A) is in the cooling operational state, refrigerant charging can be carried out from the refrigerant charging device (10) to the refrigerant cycle circuit (A) via the liquid side refrigerant line (6) (the high pressure liquid line).
