The operating sound of the outdoor unit of the central air conditioner is comparable to that of the traditional air conditioner, and the excessive noise of some central air conditioners is not only a product problem, but also may be unreasonable in design and installation that does not meet the specifications. Therefore, we must not only consider the air conditioner when choosing a central air conditioner. The mute effect of the product should also take into account the early design, on-site installation and maintenance work. It is necessary to choose a standardized and professional service provider to ensure that the noise of the central air conditioner is minimized.

1. Causes of central air-conditioning noise

1. Air conditioner quality

An important and unavoidable reason for the noise generated by the operation of the central air conditioner is that the central air conditioner itself has quality problems.

There are quality problems in the central air conditioner itself, which makes noise in the operation of the air conditioner inevitable. Poor materials in the production process of central air-conditioning, cutting corners by production line employees, sloppy work of quality inspection personnel, etc., will cause quality problems. Similarly, central air-conditioning will also have quality problems in the process of transportation and handling.

 

2. Design and installation

When installing the central air conditioner, it is often selected as a full ceiling installation. This installation method is not only for the aesthetics of the installation, but another more important reason is to reduce the noise generated by the central air conditioner when it is running. However, many designers and installers of central air conditioners have not designed it well during the design and installation process, or have designed it but have not installed it due to technical problems of the installers, which makes the central air conditioner generate noise during operation.

The design and installation location will affect the noise during operation. At the same time, if you do not pay attention to vibration and noise reduction measures during installation, it will also cause noise during operation. There are problems in the shock absorption accessories themselves, etc., which will make the central air conditioner generate noise during use.

 

3. The central air conditioner is not cleaned in time

If the central air conditioner is used for a long time, if the corresponding parts of the central air conditioner are not cleaned, it will also cause the central air conditioner to generate noise during operation.

If the central air conditioner is used for a long time, if it is not cleaned, dust will accumulate on the heat sink of the air conditioner, which will affect the operation of the central air conditioner and cause a series of problems, such as heat dissipation obstruction, abnormal air circulation of the internal unit, etc. Problems caused by the accumulation of dust on the heat sink will make the operation of the central air conditioner noisy.

 

Second, the central air-conditioning noise solution

1. Choose a high-quality brand

As for the quality of central air-conditioning, it can only be better solved when purchasing. Regarding the quality problems of the central air conditioner itself, if users are not careful when purchasing, they may be troubled by noise when using the central air conditioner. Therefore, when purchasing, we should not blindly pursue low prices, but also pay attention to the quality of central air conditioners.

To a certain extent, the brand of an air conditioner is the standard for measuring the quality of an air conditioner. Compared with other unknown central air conditioners, a central air conditioner with a good brand is not only better in quality, but also can effectively reduce the noise during the use of the central air conditioner. At the same time, if there are quality problems in use, they can be solved in time.

Of course, you must be cautious when purchasing central air conditioners. If possible, it is best to bring someone who is very familiar with central air conditioners to purchase together.

 

2. Choose a professional central air-conditioning installation company

Before installing the central air conditioner, do a good job in the design of the central air conditioner installation, fully consider various factors that will affect the normal life inside the room, and avoid these problems. Then in the installation phase, strictly implement the scheme in the design phase. In this way, the noise generated by the central air conditioner due to the design and installation process can be effectively avoided.

Choose a professional central air-conditioning installation company to design and install the air conditioner, making the installation and later maintenance of the central air conditioner more secure. A professional central air-conditioning installation company not only means enthusiastic service, good reputation, excellent technology, assured maintenance, and responsibility to users, but also strictly checks every installation link during installation to ensure that there is no error in the installation.

During the installation of central air conditioners, don't be greedy for small things. Some installation companies lure consumers with low prices, but problems often occur after installation, and repairs will bring more trouble and inconvenience to users.

 

3. Regularly clean the heat sink

Dirty heat sink is one of the reasons for the noise of the central air conditioner. Cleaning the heat sink can effectively solve the noise caused by dirty heat sink.

For the cleaning of the heat sink, you can contact after-sales professionals. After all, their cleaning skills have been affirmed, and if there is a problem, they can ask for compensation. As a large-scale equipment, the central air conditioner should not clean the cooling fins by yourself. Of course, if the air conditioner is installed by a professional installation company, you can also ask their staff to come and clean it.

 

3. For those that do not meet the requirements of indoor noise standards, the measures that should be taken when designing and installing central air-conditioning indoor units:

1. There should be a 25mm thick vibration-absorbing and sound-absorbing board under the indoor unit of the household central air conditioner, and a vibration-damping support bracket. The board should be larger than the base area of ​​the unit.

2. If necessary, install air supply and return air silencer static pressure boxes.

3. Control the wind speed in the connected air duct, preferably no more than 3m/s.

4. The length between tees, elbows, valves and other parts of the air duct should have a straight-line distance of 3 to 5 times the diameter of the air duct.

5. The indoor unit of the household central air conditioner should not be installed in the place where people stay, it is better to install it in the aisle, storage room and other places.
