Background
With the continuous improvement of the living standard of people, higher indoor environment requirements become an important part of the beautiful life of people. The central air conditioner is an important way for realizing a more comfortable indoor environment, but the running noise of the external units of various central air conditioning units is generally high, the running noise of the air-cooled screw units is about 92 decibels, the running noise of the air source heat pump units is about 73 decibels, and the running noise of the multi-connected units and the direct expansion units is about 65 decibels. The noise values are just average levels, and the noise values are different according to different machine unit brands.
The current national standards related to sound environment in China include the standard for quality of sound environment (GB 3096-. The social life environmental noise emission standard is suitable for managing, evaluating and controlling equipment and facilities used in business cultural entertainment places and business operation activities and emitting noise to the environment. The sound environment quality standard gives the environmental noise equivalent sound level limit values of various sound environment functional areas, as shown in the following table 1:
TABLE 1 ambient noise Limit
Unit: dB (A)
Applicable areas of various sound environment functional areas:
the 0-class sound environment function area is suitable for areas which need to be quiet particularly, such as rehabilitation areas, high-grade villas, high-grade hotel areas and the like. This category of areas located in suburbs and rural areas is performed in 5 db strict class 0 standards, respectively.
The type 1 sound environment functional area is suitable for areas which have main functions of residential housing, medical health, cultural education, scientific research design and administrative office and need to be kept quiet. The rural residential environment may be referred to for enforcing such criteria.
The type 2 sound environment functional zone is suitable for areas with main functions of commercial finance and martial trade, or mixed living, business and industry and needing to maintain quiet houses.
The 3-type sound environment functional area is suitable for areas which take industrial production and warehouse logistics as main functions and need to prevent industrial noise from seriously influencing the surrounding environment.
The 4-class sound environment functional area is suitable for areas on two sides of a road traffic trunk in a city and passes through areas on two sides of an inland waterway in the city. The class of standards is also enforced by the limits of background noise (meaning the noise level when not passing a train) in the areas on either side of the main and secondary rails of a railway that traverse urban areas.
According to the above standards, the residential area belongs to the type 1 acoustic environment function area, and the environmental noise limit is 55 db in the daytime and 45 db at night. Most outdoor units of the air conditioners run for 24 hours, the running noise of the air-cooled screw units is about 92 decibels, the running noise of the air source heat pump units is about 73 decibels, and the running noise of the multi-connected units and the direct expansion units is about 65 decibels, so that the environmental noise limit requirements cannot be met, and silencing measures need to be taken. Especially, when some residential areas place the central air conditioner outdoor unit in a green zone outside the building, the noise transmission and influence are difficult to control because the air conditioner main unit is lower than the residential building.
