A sound insulation assembly, and an air conditioner having same, to solve the problem of poor sound insulation. The sound insulation assembly of the air conditioner includes a housing and a cover; an accommodation space to accommodate a compressor assembly is formed in the housing; the top of the housing is covered with the cover; a sound insulation chamber is defined by the cover and the accommodation space; the compressor assembly is arranged in the sound insulation chamber; the sound insulation assembly further includes a first sealing component; the first sealing component is arranged on contact areas of the housing and the cover for sealing. The compressor assembly is arranged so that noise generated by operating of the compressor assembly can be better insulated in the sound insulation chamber.

An air conditioner includes an indoor unit and an outdoor unit. The outdoor unit includes a housing, a compressor, a first damping member, and a second damping member. The compressor is provided with a pipe. The first damping member and the second damping member each are disposed on the pipe. The second damping member is located at a preset position of the pipe. The first damping member and the second damping member are configured to change a natural resonant frequency of the pipe to a target frequency. The second damping member includes a housing assembly and a clamping groove. The clamping groove is disposed on a side of the cavity proximate to the pipe, so that a center of gravity of the second damping member deviates from a center of gravity of a portion of the pipe connected with the damping groove.

An outdoor unit of an air-conditioning apparatus includes: a terminal unit that is provided on an outer peripheral surface of a compressor, and electrically connects components provided in the compressor and outside the compressor; a side soundproof cover that covers the outer peripheral surface of the compressor except for the terminal unit; and a terminal cover that covers the terminal unit exposed from the side soundproof cover to the outside of the side soundproof cover, and soundproofs the terminal unit. The terminal cover is attached to the side soundproof cover such that the state of the terminal cover can be changed between a state in which the terminal cover covers the terminal unit and a state in which the terminal cover does not cover the terminal unit.

A beam-receiving support kit bears an outdoor condenser component of a split air conditioning system through a rigid beam. The support kit generally includes a support sleeve and a brace configured to resist rotation of the beam after the kit is incorporated into a block wall or foundation. The sleeve generally includes a straight passageway for the beam between aligned openings in the wall or foundation. The brace engages the sleeve and is generally configured to extend across a portion of at least one or two webs of a standard nominal 16″ long concrete block, and may be embedded or installed on a face of the wall or foundation. The kit may be part of a masonry unit. The kit may also comprise one or more sleeves and a liner or insulator for protecting the sleeve(s).

A switching device for a multi-split air conditioner and a multi-split air conditioner having same. The switching device has a base, a drain tank, multiple damping pads, and multiple fixing members. The base has a bottom wall and side walls, the side walls surrounding the bottom wall and extending upward from the edge of the bottom wall. The drain tank is disposed in the base, and the bottom surface of the drain tank is vertically spaced apart from the bottom wall of the base. The multiple damping pads are disposed on the drain tank and arranged at intervals in the circumferential direction of the drain tank. The multiple fixing members are respectively disposed on the damping pads and are connected to the side walls of the base. The multiple fixing members are all spaced apart from the drain tank.
