摘要： An air conditioner includes a compressor, an outdoor heat exchanger, an expansion device, an indoor heat exchanger, and a noise reduction device configured to reduce flow noise of a refrigerant. The noise reduction device includes a housing including a refrigerant inlet and a refrigerant outlet, and a plurality of baffles disposed inside the housing. The baffles include a first baffle and a second baffle that partition an inside of the housing into a plurality of spaces in a flow direction of the refrigerant. Each of the first baffle and the second baffle includes a hole through which the refrigerant passes. The holes of the first and second baffles are respectively disposed at centers of the first and second baffles at positions corresponding to each other in the flow direction of the refrigerant.
