Located in Huangdao District, Qingdao, six sets of screw air-cooled heat pump units were designed. After the unit was put into operation, the sound source affected the normal work, study and rest of the surrounding residents. The leaders of the museum attached great importance to the problem of the noise source disturbing the people, and carried out sound insulation, sound absorption and noise reduction for the installation of soundproof room for central air-conditioning equipment.
