Problems solved by technology

[0013] However, in the outdoor unit of a large air conditioner with such a structure, since the rotation speed of the inverter compressor 14b varies with the input frequency, noise is generated due to fluctuations in refrigerant pressure and vibration of the structure.
[0014] However, since the inverter compressor installed in the outdoor unit of the large-scale air conditioner of the prior art is not installed in another space such as a machine room, unlike the inverter compressor installed in a refrigerator, The partition wall in the housing (not shown in the figure) divides the space, so there is a problem that the noise generated during the operation of the inverter compressor 14b is easily discharged to the outside

Abstract

The present invention provides a noise reduction structure of an outdoor unit of a large-sized air conditioner. The outdoor unit of the large-sized air conditioner of the present invention is 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. In the outdoor unit, 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.

Description

technical field [0001] The present invention relates to an outdoor unit of a large air conditioner provided with a constant speed compressor and an inverter compressor inside, and more particularly to an outdoor unit for preventing noise generated from the inverter compressor from being transmitted to the outside of a large air conditioner Lower structure. Background technique [0002] Generally, a large-scale air conditioner is a device for keeping indoor air comfortable, and is mainly composed of the following components: an indoor unit, which is composed of an indoor blower and an evaporator, etc., and is installed on the indoor side; an outdoor unit, which is composed of an outdoor blower. , Condenser and compressor, etc., installed outside the outdoor. [0003] figure 1 It is a perspective view showing an outdoor unit of a conventional large-scale air conditioner. [0004] Such as figure 1 Shown, the outdoor unit of existing large-scale air conditioner is made of fo...
