    Abstract: A ventilation apparatus includes: a housing including a first inlet through which outside air is sucked, a second inlet through which room air is sucked, a first outlet through which air is supplied to an indoor space, and a second outlet through which air is discharged to an outdoor space; an outside temperature sensor configured to measure a first temperature of the outside air; a room temperature sensor configured to measure a second temperature of the room air; a total heat exchanger configured to perform heat exchange between the outside air and the room air; a first blower communicating with the first outlet; a second blower communicating with the second outlet; and a processor to perform a drying operation for the total heat exchanger by operating at least one of the first blower or the second blower, based on a difference value between the first temperature and the second temperature.

    Abstract: 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.
