Description

Air Conditioner {Air Conditioner}

The present invention relates to the reduction of refrigerant sound generated when a refrigerant is compressed by a compressor and passed through a controlled component such as an electric valve of an air conditioner that performs air conditioning by inverting the circulation direction of the refrigerant by a four-way valve. .

Until now, the generation of sound or the sound absorption have been prevented by a dustproof material that is used by attaching a sticky plate, such as a non-bin, to the refrigerant sound generated when passing through the controlled component or the refrigerant pipe.

However, dust-proof materials with adhesiveness such as vivins are difficult to work with, such as unstable positioning and shape, and are adhered to unexpected places due to their adhesiveness during assembly work. When inspecting or replacing parts, there is a case where the dustproof material such as the above-mentioned vibrate needs to be removed, and there is also a problem in terms of workability.

In addition, since once used Vivine can not be reused and disposed of, it has a concern about the environment.

Accordingly, an object of the present invention is to provide an air conditioner, which can be reused, specifies the attachment position and shape, and reduces the refrigerant sound by using a dustproof material having improved workability. .
