<p>In order to prevent drain water generated in a heat-source-side heat exchanger from refreezing, a heat-source-side heat exchanger (8) of an air-conditioning device (1) comprises multiple divided heat exchangers (17a-17c) having mutually different refrigerant paths, with each of the divided heat exchangers (17a-17c) containing a first path (81) arranged at the lowest part and containing other, second paths (82). In addition, the heat-source-side heat exchanger is equipped with: a branch part (23) that branches a refrigerant transmitted from a usage-side heat exchanger (11) during a heating operation and supplies the refrigerant to the first path (81) of each divided heat exchanger; a first confluence part (26) that combines the refrigerant that has passed through the first paths (81); a flow-dividing part (18) that again branches the refrigerant combined by the first confluence part (26) and decompresses the refrigerant, and supplies the refrigerant in parallel to the liquid-side end of the second path (82) of each divided heat exchanger; and a second confluence part (19) that combines the refrigerant flowing from the gas-side end of the second paths (82).</p> |
