Abstract (en)
[origin: EP2034261A1] The labor of inputting information on a refrigerant communication pipe before operating a separate type air conditioner is minimized, and at the same time, the adequacy of the refrigerant quantity in a refrigerant circuit can be judged with high accuracy. An air conditioner (1) includes a pipe volume calculating means and a refrigerant circuit (10) configured by the interconnection of a heat source unit (2) and a utilization unit (4, 5) via a refrigerant communication pipe (6, 7). The pipe volume calculating means calculates the volume (Vlp, Vgp) of the refrigerant communication pipe (6, 7) based on an additional charging quantity (Ma) which is a refrigerant quantity to be additionally charged after the refrigerant circuit (10) is configured by interconnecting the heat source unit (2) and the utilization unit (4, 5) via the refrigerant communication pipe (6, 7).
