PROBLEM TO BE SOLVED: To improve reliability of an air conditioner by suppressing liquid compression in a compressor at non-steady time, regarding the air conditioner which uses R32 as a circulating refrigerant in a refrigeration cycle including the compressor, an indoor heat exchanger, expansion means and an outdoor heat exchanger.SOLUTION: In an air conditioner which uses R32 as a circulating refrigerant in a refrigeration cycle including a compressor, an indoor heat exchanger, expansion means, and an outdoor heat exchanger, in the case where a capacity class of the air conditioner is below 4 kW, a filling amount of the R32 with respect to the refrigeration cycle is within a range of 200-300 g per total volume 1 liter of the whole refrigeration cycle, and in the case where the capacity class of the air conditioner is equal to or greater than 4 kW, the filling amount of the R32 with respect to the refrigeration cycle is within a range of 250-350 g per total volume 1 liter of the whole refrigeration cycle.SELECTED DRAWING: Figure 4 |
