What if the noise of central air conditioner is too loud?

Central air conditioning is a high-power electrical appliance, which is not only large in volume, but also very noisy. If not designed and installed properly, serious noise will be generated. The excessive noise of central air conditioning not only affects work and rest, but also may affect neighbors, which is very unfavorable to people. Therefore, when selecting and installing the central air conditioner, the noise reduction scheme must be carried out to minimize the noise of the central air conditioner.

1. The project budget does not consider the supervision and inspection cost of air conditioning project, the contradiction between market economy and low price bid winning and the interests of the company, the restriction of supervision and inspection mechanism is insufficient, and the setting quality of central air conditioning is difficult to guarantee.

2. Civil engineering, air conditioning and decoration cannot be coordinated and communicated, and air conditioning design, installation size and installation position often change.

3. The existence of the criterion of winning the bid at a low price in the bidding enables the engineering party to select a non professional and low-cost installation team, so as to sacrifice the project quality and obtain the survival profit of the company, so that the professional installation unit is defeated by the non professional guerrillas at a low price.

Muffler and ventilation air shall be used to adjust the position of the refrigeration room. Do not be close to the room with high noise environment requirements. When approaching, sound insulation and vibration reduction scheme shall be carried out. The ventilation and air conditioning system will form noise. When the natural attenuation cannot achieve the allowable noise standard, silencing device shall be set or its silencing scheme shall be carried out.

The phenomenon of cutting corners in the manufacturing and installation process of air duct is more serious. For example, the deflector should be installed, the corner should not be considered at the corner, the size of the air duct is inconsistent with the air supply volume, the thickness of the metal plate of the air duct is inconsistent with the size of the air duct, air leakage at the joint between the connecting hose and the air duct, etc. these non-standard installation will increase the noise formed in the air supply process.

1. Review: strengthen the review of mandatory specifications and energy-saving requirements in the design review, review the qualification of the setting department, the effectiveness of the quality assurance system, the ability to modify the design and technical equipment in the setting.

2. Inspection: formulate and implement the inspection rules and regulations for air conditioning installation process and completion acceptance, authorize qualified inspection institutions to formulate inspection items according to relevant national standards and specifications, and be responsible for the effective inspection of air conditioning projects.

3. Supervision: mainly check whether the purchased raw materials, terminal equipment and host equipment meet the design requirements, confirm the qualification of the installation department entering the construction site, and prevent the inconsistency between the installation department and the bid winning department.

The excessive noise of central air conditioning involves all aspects, which is almost accompanied by the whole process of air conditioning system. When selecting central air conditioning, users should not only consider the mute effect of air conditioning products, but also consider the preliminary design, on-site installation and maintenance.
