Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a refrigeration cycle device which effectively suppress dew formation in the vicinity of a blowout port of an indoor unit, without having to depend on a heat-insulating material. SOLUTION: The refrigeration cycle device executes dew formation suppression control operation for adjusting the opening of a throttling device 102 and suppressing the dew formation state of a use side heat exchanger 101, by comparing superheat SH of the use side heat exchanger 101 with lower limit value superheat SHO in a dew formation region set, based on relative humidity of an air conditioning target region, to which air generated by the use side heat exchanger 101 is supplied, and comparing the liquid refrigerant temperature Te made to flow in the use side heat exchanger 101, with the upper limit value liquid refrigerant temperature TeO in the dew formation region.
