Problems solved by technology

Also, since fairly fine filters are required, there are cases where dust etc. clogs the filter and, in worst case, the refrigerant circuit
In addition, when the filter area is increased to prevent the above phenomenon, a large installation space is required
[0010] In addition, in order to reduce noise, the filter needs a certain width, and multiple filters are required, so the cost becomes high
And by the opening and breaking of the filter itself, powder is generated, so there is a case where dust is generated by the filter itself and the refrigeration cycle is blocked
In addition, the density of the filter itself cannot be made uniform and the mute effect becomes inconspicuous, or powder is generated from the outlet of the filter and impurities flow into the throttling device

Embodiment 2

[0021] Since the filter in Example 1 is formed by compressing metal iron wire, even a small amount of powder may be generated and may be cut. In Example 2 of the present invention, if the filter is formed of a single iron wire or a twisted metal wire without a cut in the middle, it is difficult to break the wire.

Embodiment 3

[0023] In order to make the density of the filter in Example 1 uniform and to obtain the maximum sound-absorbing effect in the smallest space, in Example 3 of the present invention, the iron wire is first processed into a spiral shape, and then it is compressed, so that the filter metal The mesh density is uniform and low noise effect can be obtained.

Embodiment 4

[0025] figure 2 It is a sectional view of the noise reduction device of Embodiment 4 of the present invention. A filter holder 33 , in which a filter 32 is caulked, is inserted into the silencer main body 31 . The throttling device 34 is installed on one end of the main body 31 of the noise reduction device directly or through a lead pipe. A copper pipe 35 is attached to the silencer main body 31 on the side opposite to the throttle 34 . A bypass pipe hole 37 connected to a bypass passage 36 through which the refrigerant bypasses the filter 32 and flows is formed in the muffler device main body 31 . The noise reduction device is arranged on the main flow of the refrigerant, and almost all the refrigerant passes through the filter 32 inside the noise reduction device. However, there is a possibility that impurities may be mixed in and accumulated in the filter 32 during the refrigeration cycle, thereby clogging the filter 32 . At this time, since the refrigerant flows thro...

Abstract

A silencer of the air conditioner, in a refrigeration cycle including an indoor unit heat exchanger, an outdoor unit heat exchanger, and a throttling device, a silencer having a filter formed by compressing a single metal wire or un-cut strand wire inside is disposed. The silencer suppresses noise released from the throttling device. The silencer prevents adverse effects of dust generated in the refrigeration cycle on the refrigeration cycle.

Description

technical field [0001] The present invention relates to a noise reduction device provided in an air conditioner of a refrigeration cycle. Background technique [0002] In recent years, it is necessary to install a decompression device (throttle device) on the indoor unit of an air conditioner that generally has a reheating and dehumidification function. And since the refrigerant sound is generated in the throttling device, it is an important issue to prevent the above-mentioned sound from being directly transmitted to the users who live indoors. [0003] The refrigeration cycle has a compressor, a refrigerant line connecting the indoor heat exchanger and the outdoor heat exchanger, and a refrigerant flow rate adjustment mechanism. The reheating and dehumidification function means that the indoor unit is equipped with a decompression device for using a part of the indoor heat exchanger as a condenser and the rest as an evaporator, thereby increasing the temperature as a cond...
