ABSTRACT:
A multi-type refrigerator is capable of achieving a high coefficient of performance (COP) while using R32 as refrigerant and that takes account of energy saving and global warming. Refrigerating cycles are executed by circulation of R32 as refrigerant through a refrigerant circuit including one outdoor unit having a compressor, a condenser, and expansion means and a plurality of indoor units having evaporators. A filling quantity of R32 for the refrigerant circuit is set in a range from 120 to 300 g/kW (refrigerating capacity). The filling quantity of R32 for the refrigerant circuit is set in a range from 84 to 300 g/L (internal volume of the condenser).
