PROBLEM TO BE SOLVED: To provide an air-conditioning device that can evaporate drain water efficiently.SOLUTION: An air-conditioning device includes a refrigerant circuit in which a compressor, a heat source-side heat exchanger, a first throttle mechanism, a second throttle mechanism, and a use-side heat exchanger are connected by a refrigerant pipe, and which allows a refrigerant to circulate. The device includes: a fan 51 that allows air to flow to the use-side heat exchanger 35; a use-side control unit 102 that includes a switching element formed by a wide bandgap semiconductor and drives the fan 51; a heat sink 120 that radiates heat generated in the switching element; and a drain pan 130 that is provided at a lower part of the use-side heat exchanger 35 and stores a droplet dropped from the use-side heat exchanger 35. The heat sink 120 is arranged in contact with or in the vicinity of the drain pan 130. |
