574489 V. Description of the invention (1) Technical field of the invention The present invention relates to an air-conditioning device for compressing a refrigerant by a compressor, and inverting a circulation direction of the refrigerant by a four-way valve to perform air conditioning. The occurrence of refrigerant sounds is reduced. The conventional technology has been that, for the refrigerant sound generated when passing through the controlled component or the refrigerant piping, a plate-shaped person having an adhesive on one side of a soft vibration-proof material is attached to the control component or the refrigerant. The piping is used as an anti-vibration material to prevent sound from occurring or to absorb sound. Problems to be solved However, this type of vibration-proof material does not have a specific attachment position or shape, and when it is assembled, it is difficult to display the surface by its adhesiveness, etc. When inspecting or replacing parts during maintenance, there are occasions where the above-mentioned vibration-proof material needs to be removed, which becomes a problem in terms of workability. In addition, once the vibration-proof material is used once, the effect of the adhesive on one side is reduced, and the relationship between "disposable use" and "disposal" becomes a concern on the environmental side. Therefore, an object of the present invention is to provide an air-conditioning apparatus which is characterized by a reusable anti-vibration material capable of specifying the installation position and shape and improving workability to reduce refrigerant sound. Means to Solve the Problem The invention described in item 1 of the scope of patent application is for an outdoor unit included in an air conditioner, and the interior of the casing is divided by a partition plate extending vertically to form a heat exchanger chamber and Machine room, equipped with refrigerant in this machine room
