Based on years of experience of noise control field and the actual situation of East Star Refrigeration Engineer, scroll type air-cooled heat pump installation using noise control scheme of configuration of sound insulation cover noise control of the specific plan is as follows:
      1, through the sound insulation performance of the sound insulation performance of the vortex type air cooling heat pump unit running sound insulation, so that it can not spread the spread of noise, pollution of the environment.
      2, through the sound insulation cover sound-absorbing material, noise in vortex type air cooled heat pump units have not changed, with reduced cover radiation and reverberation strike frequency to reduce the noise intensity, reducing noise, reduce noise.
     3, through the sound insulation cover the intake and exhaust muffler system, to ensure the normal temperature and exhaust volume, air-cooled heat pump units scroll the standard for the case of eliminating noise, the noise will not spread out, the pollution of the environment. To ensure the overall noise reduction effect.
     4, the compressor is the main noise equipment, according to the needs of the design without affecting its normal operation on the basis of sound insulation management, help to improve the overall noise reduction effect.
     5, in order to ensure the maintenance of the vortex type air-cooled heat pump unit, the sound insulation cover is provided with a sound insulation inspection door and a maintenance channel, which can ensure the maintenance personnel to enter and exit, and the noise does not spread outwards.
     6, in order to ensure the daily maintenance and repair, the sound insulation cover for need to overhaul the position to leave some space for maintenance, at the same time, sound insulation cover top access port for the inspection of the equipment, operation and maintenance, the vortex type air cooled heat pump can maintain good working condition.
