AIR CONDITIONING DEVICE

Abstract

The present disclosure relates to a noise shielding device for implementing low noise in a heat pump outdoor unit of an air conditioning device (e.g. an air conditioner). The noise shielding device may comprise: a housing comprising a first surface exposed to the outside, open in the upward direction, and comprises a first sound insulating member comprising a sound insulating material in which a compressor is accommodated in an internal space thereof; and at least one first anti-vibration groove formed on the first surface of the first sound insulating member.

Description

BACKGROUND

Field

The disclosure relates to an apparatus for reducing noise of a compressor provided in an outdoor unit that makes up an air conditioning device (e.g., an air conditioner).

Description of Related Art

Apparatuses or devices used in an air conditioning facility may vary depending on its air conditioning scheme, and may be roughly categorized as an air conditioning device, a heat source device, a refrigerant carrier system or the like. In general, an air conditioning device such as e.g., an air conditioner may include a housing to house such an air conditioning unit therein. In order to reduce noise from a compressor, the housing may include materials with an overlapping structure of a sound-insulation member and a sound-absorption member.

The sound-insulation member of the housing may serve to block sound, and the sound-absorption member of the housing may serve to absorb sound. A combination of materials of the sound-absorption member and the sound-insulation member is referred to as a sound absorption/insulation member.

While the noise of 400 Hz or more generated from the compressor of the air conditioning device may be reduced with such a sound absorption/insulation member, the noise of 400 Hz or less may have a limited effect in reduction even using the sound absorption/insulation member, and low-frequency noise may be amplified due to vibrations of the sound-insulation member.

The thickness of the sound-insulation member applied to the compressor of the air conditioning device may have a uniform structure. In such a structure of sound-insulation member, vibrations may occur on its surface due to vibration or sound of the compressor, which is transmitted to the entire sound-insulation member to cause vibration like a plate, thereby amplifying low-frequency noise (especially in 400 Hz or less).

SUMMARY

Embodiments of the disclosure may provide an air conditioning device provided with an anti-vibration groove on a surface of a sound-insulation member that shields noise generated by a compressor provided in an outdoor unit.

Embodiments of the disclosure provide a noise shielding device capable of improving a phenomenon of noise amplification, by forming at least one anti-vibration groove on the surface of the sound-insulation member for improving the phenomenon of the low-frequency noise of 400 Hz or less being amplified, and even if vibrations occur on the surface of the sound-insulation member, minimizing and/or reducing transmission of the vibrations throughout the sound-insulation member.

According to an example embodiment of the disclosure, an air conditioning device may comprise: one or more indoor units, an outdoor unit connected via piping to the one or more indoor units and including a compressor, and a housing configured to be opened upward and including a first sound-insulation member comprising a sound-insulating material accommodating the compressor in an inner space thereof, and wherein at least one first anti-vibration groove may be formed on a first surface exposed to an outside in the first sound-insulation member included in the housing.

According to an example embodiment of the disclosure, a housing configured to shield noise from a compressor provided in an outdoor unit of an air conditioning device may comprise: a sound-insulation member comprising a sound-insulating material having an inner space, opening upward, and including one surface exposed to an outside; and at least one anti-vibration groove formed on the one surface.

According to various example embodiments of the disclosure, it is possible to minimize and/or reduce the phenomenon of amplification of low frequency noise of 400 Hz or less, by forming at least one anti-vibration groove on the surface of the housing provided for shielding noise generated by an outdoor unit of an air conditioning device.

FIG. 4 is a diagram illustrating an example process of attenuation of vibrations generated in the sound-insulation member, according to various embodiments.

Referring to FIG. 4, according to an embodiment, when a difference in the material or surface cross-sectional area of the housing 10 occurs in a transmission path of noise/vibrations generated in the surface of the housing 10 (e.g., the first housing 101 of FIG. 2A or the second housing 102 of FIG. 2B), a noise or vibration reflection may be generated at the corresponding portion (e.g., due to impedance mismatching), and a vibration reflection may be generated using the difference in the cross-sectional area of the noise or vibration transmission path.

According to an embodiment, vibrations are generated in a certain portion of the first sound-insulation member 13 or the second sound-insulation member 17, which vibrations are transmitted through one surface of the first sound-insulation member 13 or the second sound-insulation member 17, and some vibrations are then reflected at a portion where the cross-sectional area rapidly changes in the sound transmission path (e.g., a portion where the first anti-vibration groove 133 is formed or another portion where the second anti-vibration groove 136 is formed), consequently resulting in an overall vibration attenuation effect in the course of propagating the vibration throughout the first sound-insulation member 13 or the second sound-insulation member 17.

Assuming that the first sound-insulation member 13 or the second sound-insulation member 17 according to an embodiment is an infinite plate, as the vibration (vibration speed v) of the first sound-insulation member 13 or the second sound-insulation member 17 is reduced, the acoustic power generated by the plate vibration may decrease in proportion to the square of the vibration speed, as defined by Equation 1 below,

[Equation 1]

W=ρcsυ²

• • wherein W is an acoustic power (Watt),
  • ρ is a density of air (kg/m²),
  • c is an air speed (m/s),
  • s is an area of sound-insulation material (m²), and
  • v is a vibration speed of sound-insulation material (m/s²)

FIG. 5 is a graph illustrating an experimental result indicative of alleviating noise due to a compressor in an air conditioning device, according to various embodiments.

Referring to FIG. 5, the insertion loss may refer to a difference between the noise from a sound source (e.g., compressor 20) and the noise when the sound source is sealed with the sound-absorption member (e.g., the first sound-absorption member 14 of FIG. 3 or the second sound-absorption member 18 of FIG. 3) and/or the sound-insulation member (e.g., the first sound-insulation member 13 of FIG. 3 or the second sound-insulation member 17 of FIG. 3). The solid line graph represents the noise caused by the sound source when the source is not sealed by the sound-absorption member and/or the sound-insulation member. The dashed line graph represents the noise caused by the sound source when the source is sealed by the sound-absorption member and/or the sound-insulation member.

According to an embodiment, the insertion loss greater than zero may refer, for example, to the noise being reduced after applying the first sound-absorption member/the first sound-insulation member compared to before applying the first sound-absorption member/the first sound-insulation member, and conversely, the insertion loss less than zero may refer, for example to the noise being amplified.

According to an embodiment, in the case of the sound-absorption member/sound-insulation member to be provided in the compressor 20 of the air conditioning device, the noise is inversely amplified due to the vibration of the sound-insulation member in a region of 400 Hz or less, and thus the insertion loss value may usually have a value of zero or less.

In conclusion, according to an embodiment, the insertion loss in the region (e.g., 400 Hz or less) where the insertion loss becomes zero or less shows an effect that the octave band average is improved by 3.7 dB.
