Description

outdoor unit of air conditioner {air conditioner out door unit}

This specification relates to an outdoor unit of an air conditioner.

In general, an air conditioner is equipped with a refrigeration cycle device consisting of a compressor, a condenser, a capillary tube, and a heat exchanger. It is a device that keeps the atmosphere pleasant.

The air conditioner is divided into a window type air conditioner in which a refrigeration cycle device is mounted in one body and installed on a window, and a separate type air conditioner in which an indoor unit and an outdoor unit are separated and installed indoors and outdoors, respectively. The outdoor unit of the separation type air conditioner generally includes a compressor, a condenser, and a cooling fan that generate a lot of noise, and the indoor unit includes an evaporator and a blower fan.

On the other hand, when the air conditioner is operated, the outdoor unit generates noise, and the main cause of the noise is the compressor and the axial fan. The noise generated by the axial fan is a wide-band flow noise having uniform noise energy in a wide frequency range, and the noise generated by the compressor is a peak sound existing in a wide frequency range as a harmonic component of the compressor operating frequency. The noise generated by the axial fan accounts for about 40% of the total noise, and the noise generated from the compressor accounts for about 50%. It's an annoying annoying noise.

Accordingly, various means for reducing the noise of the outdoor unit have been proposed.

1 and 2 are cross-sectional views illustrating an outdoor unit of an air conditioner having a noise blocking structure according to the related art.

1 and 2, the outdoor unit 10 of the conventional air conditioner includes a case 12 forming an inner space, a compressor 14 and a gas-liquid separator 16 installed in the inner space of the case, A noise isolation device 24 surrounding the compressor 14 and the gas-liquid separator 16 is included.

In addition, an inlet pipe 20 for introducing the refrigerant into the gas-liquid separator 16 and a four-way valve 22 for determining the flow direction of the refrigerant are provided on the compressor 14 and the gas-liquid separator 16, and A discharge pipe 18 for discharging the refrigerant compressed in the compressor 14 is provided.

Accordingly, in order to reduce the noise generated inside the outdoor unit 10, a method of enclosing a sound absorbing and insulating material on the side surfaces of the compressor and the gas-liquid separator as the noise blocking device 24 was adopted. Since radiated noise due to vibration is generated from the pipe 20 and the four-way valve 22, when the pipe and the valves 18, 20, and 22 are exposed as shown in FIG. 1, the noise of the outdoor unit is directly radiated to the outside. there is a problem.

In addition, as shown in FIG. 2 , it has been proposed to install a sound absorbing and insulating material including pipes and valves 18 , 20 , and 22 , but in this case, the volume of the outdoor unit increases and the unit price of the product increases.

An object of the present invention is to provide an outdoor unit of an air conditioner for preventing vibration noise generated by a compressor of the outdoor unit from being radiated to the outside.

According to one aspect, an outdoor unit of an air conditioner includes: an outdoor unit case forming an inner space; a compressor installed inside the outdoor unit case to compress the refrigerant; a gas-liquid separator installed on one side of the compressor; a sound absorbing and insulating material surrounding the outside of the compressor and the gas-liquid separator; and a cover provided on one side of the sound absorbing and insulating material to shield at least one or more pipes connected to the compressor or the gas-liquid separator.

According to the proposed invention, it is possible to prevent the vibration noise generated from the compressor of the outdoor unit from being radiated to the outside through the coupling of the sound absorbing and insulating material and the cover.

In addition, it is possible to prevent an increase in the volume of the outdoor unit through the groove of the cover.

In addition, through the fitting structure of the sound absorbing and insulating material, the sound absorbing and insulating material can be used in a saving manner.

3 and 4 , in the outdoor unit 100 of the air conditioner according to the present embodiment, a case 101 forming an inner space, a compressor 110 installed in the inner space of the case 101, and a gas-liquid The separator 120 and noise blocking devices 130 and 140 surrounding the compressor 110 and the gas-liquid separator 120 are included.

As an example, the case 101 has a rectangular parallelepiped shape, and a support member 115 for supporting the compressor 110 is included at an inner lower portion of the case 101 .

The gas-liquid separator 120 is understood as a configuration for separating a gaseous refrigerant from among the refrigerants to be introduced into the compressor 110 and supplying it to the compressor 110 .

The inside of the case 101 includes a suction pipe 125 connecting the outlet side of the gas-liquid separator 120 and the suction side of the compressor 110 . Accordingly, the gas-phase refrigerant separated in the gas-liquid separator 120 is sucked into the compressor 110 through the suction pipe 125 .

In addition, an inlet pipe 124 for introducing a refrigerant into the gas-liquid separator 120 is installed at the upper end of the gas-liquid separator 120 .

The outdoor unit 100 includes a four-way valve 122 that guides the refrigerant discharged from the compressor 110 toward the outdoor heat exchanger or the indoor heat exchanger. One or more four-way valves 122 may be installed inside the outdoor unit.

For example, the four-way valve 122 may be located at the upper center of the compressor 110 and the gas-liquid separator 120 .

The compressor 110 sucks the gas-phase refrigerant separated from the gas-liquid separator 120 from the suction pipe 125 and compresses the gas-phase refrigerant to a high temperature and high pressure state. The compressed gaseous refrigerant is discharged through a discharge pipe 112 extending in the longitudinal direction from the upper portion of the compressor 110 .

Meanwhile, although not shown, the outdoor unit 100 of the air conditioner according to an embodiment of the present invention may include an outdoor heat exchanger that exchanges heat with the outside air and a blower fan that generates a flow of the outside air.

As described above, a plurality of pipes 112 , 122 , and 124 extending from the compressor 110 or the gas-liquid separator 120 are installed in the outdoor unit 100 . Among the plurality of pipes 112 , 122 , and 124 , the discharge pipe 112 is configured to discharge a gaseous refrigerant having a very small specific gravity, and thus extends upward from the compressor 110 to guide the discharge of the refrigerant.

Meanwhile, the refrigerant introduced through the inlet pipe may include a liquid refrigerant and a gaseous refrigerant. In order to allow the liquid refrigerant to easily flow into the gas-liquid separator 120 , the inlet pipe 124 is disposed to extend from the upper side of the gas-liquid separator 120 to the gas-liquid separator 120 .

Although not shown in the drawings, another pipe may be further installed inside the outdoor unit, and the plurality of pipes 112 , 122 , and 124 need to be installed so as not to interfere with the other pipe.

The compressor 110 is a configuration in which the refrigerant is compressed at a high pressure, and thus a lot of vibration or noise may occur. In addition, vibration or noise generated by the compressor 110 may be transmitted to the plurality of pipes 112 , 122 , 124 or the gas-liquid separator 120 to cause vibration or noise of the entire outdoor unit 100 . Therefore, it is required to block such vibration or noise.

The outdoor unit 100 is provided with noise blocking devices 130 and 140 .

The noise blocking devices 130 and 140 include a sound absorbing and insulating material 130 simultaneously covering the outside of the compressor 110 and the gas-liquid separator 120 , and a cover 140 covering the upper end of the sound absorbing and insulating material 130 . .

The sound absorbing and insulating material 130 simultaneously surrounds the outside of the compressor 110 and the gas-liquid separator 120 , and couples the opposite ends of the sound absorbing and insulating material 130 facing each other to fix the sound absorbing and insulating material.

The sound absorbing and insulating material 130 is installed at a predetermined distance from the surfaces of the compressor 110 and the gas-liquid separator 120 . This is because, when vibrations caused by the driving of the compressor 110 and the gas-liquid separator 120 are transmitted to the sound absorbing and insulating material 130, noise may be generated from the sound absorbing and insulating material 130 itself. This is to prevent the vibration from being transmitted by spaced apart from the gas-liquid separator 120 by a predetermined distance.

The sound absorbing and insulating material 130 includes one end forming the first connecting portion and the other end forming the second connecting portion. The first connection part and the second connection part may be coupled to each other in a fitting manner, and may be disposed to surround the compressor 110 and the gas-liquid separator 120 .
