The precision air conditioning of the computer room is the key equipment to ensure the constant temperature and humidity of the data processing facilities. However, even under normal operation, a precision air conditioner may emit non-faulty noise. In order to improve the operational quality of data processing facilities, it is necessary to analyze the causes of non-faulty noise and take appropriate measures.
Causes that can cause non-faulty noise from precision air conditioners:
Worn or unbalanced precision air conditioner fan blades.
Vibration inside the precision air conditioning compressor.
Interference with the airflow of the condenser or evaporator of the precision air conditioner.
Deterioration of the performance of the interior or exterior sound insulation materials of precision air conditioners.
Precision air conditioner installation or bracket issues.
Electromagnetic interference between electrical components of precision air conditioners.
Internal resonance problems in precision air conditioners.
Analyze solutions or improvements based on the above causes to mitigate or eliminate noise problems.
Balance or replace the fan.
Repositioning or reinforcement of precision air conditioning compressors.
Optimize the airflow design of precision air conditioning condensers and evaporators.
Upgrade or repair precision air conditioning sound insulation.
Check and adjust the precision air conditioner bracket.
Improve the layout of the electrical components of precision air conditioners or use EMI suppression measures.
Re-immobilize or isolate the resonant part.
