A Simple Blog PostHow to control the high noise of the air conditioning unit in Anhui New Culture Square?A Simple Blog Post

The air conditioning unit is an important component of the air conditioning system, which often emits noise during operation. Some old air conditioning units emit particularly loud noise. So, what should we do if the air conditioning unit has high noise?

If it is a household air conditioner with a small scale, you can look for an air conditioning repair shop to solve the problem of high noise in the air conditioning unit. If it is a commercial air conditioner or an industrial air conditioner, the scale is relatively large, and there are many issues that need to be paid attention to. It is necessary to find a professional sound insulation company to solve them. This week, Hongrun Acoustics will explain with a recent engineering case – Anhui New Culture Square.

The air conditioning unit is an important component of the air conditioning system, responsible for regulating the temperature, humidity, and cleanliness of indoor air. Due to the differences in central air conditioning systems, the composition of air conditioning units also varies, with two types: multi unit air conditioning systems and chiller systems.

Noise analysis of air conditioning units
The air conditioning unit belongs to the air conditioning host system, and there are two main sources of noise, namely the noise emitted by the fan and the noise emitted by the compressor, both of which belong to aerodynamic noise, with a noise spectrum of medium and low frequencies.

The noise emitted by fans and compressors, although mainly aerodynamic noise, can also emit mechanical and electromagnetic noise, which are relatively low and exhibit characteristics of strong low-frequency and wide frequency band.

Methods to avoid noise from air conditioning units
The problem of high noise in air conditioning units can be solved from multiple perspectives, and these problems can be avoided during purchase and installation. The specific methods are as follows:
01 Select low-noise equipment
The air conditioning unit includes various noise equipment, such as ventilation fans, refrigerators, water pumps, etc. These equipment are inherently high noise equipment. When purchasing these equipment, choosing low noise equipment can reduce the impact of noise.

02 Sound insulation and shock absorption measures
During the installation of various equipment in the air conditioning unit, sound insulation and vibration reduction measures can be taken, such as avoiding contact between vibrating equipment and walls, conducting sound insulation treatment in the air conditioning room, and avoiding bending during the installation of air conditioning pipelines, all of which can reduce the noise of the air conditioning unit.
