(54) Noise reduction structure of outdoor unit of large-sized air conditioner


(57) Disclosed is a noise reduction structure of an outdoor unit of a large-sized air conditioner provided with a constant-speed converter and an inverter converter for compressing a refrigerant so as to circulate the refrigerant through a refrigerating cycle to variably change air-cooling capacity of the air conditioner. Particularly, an anti-noise barrier provided with protrusions surrounds the inverter compressor, thereby preventing noise generated from the inverter compressor from being transmitted to the outside.
