Shell and air conditioner

The embodiment of the utility model discloses a shell and an air conditioner. The shell comprises a shell body, a shell cover and a shell cover, the air outlet duct is arranged on the shell body, and a sound absorption area is formed between the air outlet duct and the shell body; the sound absorption part is arranged in the sound absorption area, the sound absorption part is connected to the air outlet channel, and a sound absorption cavity is formed in the sound absorption part. Through the arrangement, noise generated when airflow passes through the air outlet channel can be absorbed through the sound absorption part, the structure of the air outlet channel does not need to be modified, meanwhile, the flow channel area of the air outlet channel is not affected, the research and development cost of the air outlet channel is reduced, the noise of the air outlet channel is absorbed through the physical structure of the sound absorption cavity while the air outlet amount of the air outlet channel is guaranteed, the structure is simple, and cost is reduced; and user experience is improved.
