To provide an air conditioner that can suppress increase of pressure loss by reducing a refrigerant circulation amount without degrading heat exchanging performance, in the air conditioner including a heat exchanger applying flat tubes.
The air conditioner 100 includes a housing 1 having a suction opening 1a and a supply opening 1b, and an air distribution fan 10 and the heat exchanger 20 disposed in the housing 1. The heat exchanger 20 has a plurality of flat fins 31 stacked at prescribed intervals, and a plurality of flat tube-shaped heat transfer tubes 36 inserted into the flat fins 31 and disposed along the stacking direction of the flat fins 31. This air conditioner 100 uses R32 as a working refrigerant, and a charging amount of the R32 to the air conditioner 100 is smaller than that of R410A in an air conditioner exerting the same performance as that of the air conditioner 100 by using R410A as a working refrigerant.
