Zusammenfassung:	Provided is a refrigeration cycle device wherein each of a plurality of sets of air heat exchangers is a set of one or more stand-alone heat exchangers. The stand-alone heat exchanger has an upper header pipe, a lower header pipe, heat transfer tubes, and fins. During cooling operation, a serial refrigerant channel is formed in which the air heat exchangers of each set circulate refrigerant in series and in which the refrigerant flows from the top to the bottom of the heat transfer tubes of all of the stand-alone heat exchangers. During heating operation, a parallel refrigerant channel is formed in which the air heat exchangers of each set circulate the refrigerant in parallel and in which the refrigerant flows from the bottom to the top of the heat transfer tubes of all of the stand-alone heat exchangers.
