The Actual Cooling Effect And Noise Treatment Method Of Cabinet Air Conditioner

1. Identify the expected effect of refrigeration, and see if it is possible to give the necessary temperature in the case in less time at the beginning. Because minimizing the space in the case, the design and the temperature range of the design solution are different. If you consume as much mechanical energy as possible per unit time, you can reduce the temperature, which means that the cost of applying it is very high, which will cause the company's cost. rise.

2. Because many companies have high regulations on the output power of cabinet air conditioners, they try to be aware of the adverse effects they will cause during operation. Before the cabinet air conditioner is operated, it is possible to carefully test whether the instrument parts have difficult problems, and immediately adjust the appropriate operation plan, and most of the various common problems of industrial equipment can be eliminated.

3. Even if high-quality industrial cabinet air conditioners have been used for many years, there will not be too many difficult problems. According to the investigation and analysis report, the industrial production refrigeration equipment manufactured by imported spare parts will not cause all difficult problems even if the service life exceeds 5 to 8 years. Naturally, it is helpful to reduce the difficult problems of industrial equipment. The company tries its best to carry out continuous maintenance on industrial equipment, realizes the adverse effects of industrial air conditioners, and immediately identifies difficult problems, so that the reliability of industrial equipment operation can be maintained and improved Sign up for working hours and industrial equipment service life.

How to reduce the noise pollution of industrial air conditioners?

Industrial cabinet air conditioners have noise pollution, and there is a certain amount of noise pollution during operation. The noise source (exciting force of noise) is mainly concentrated in the refrigeration unit system software, cooling fan system software, and movable structure prefabrication. Components, refrigerant fluidity, etc. As a company with professional capabilities and assets to produce and manufacture air conditioners, scientific research and reducing noise pollution from industrial air conditioners are one of the main points of its work to reduce noise pollution from industrial air conditioners

The important part of noise is solid-state and air-borne. The market share of the mechanical kinetic energy of gas and solid-state dissemination of noise is different due to changes in structure and noise frequency. Low-frequency noise is mainly caused by solid-state dispersion, while high-frequency noise is mainly caused by air transmission. The key to noise control of cabinet air conditioners starts from three levels:

One is to remove or renovate the noise source of the background wall;

The second is to block the vibration transmission connection between Shifeng and the shell, and block the solid-state dissemination;

The third is to carry out the active control of the shell vibration, and eliminate the noise according to the reduction of the vibration. The refrigeration unit system software is one of the key noise sources of industrial air conditioners. Here, the low and high frequency mechanical equipment noise is carried out according to the pipeline system software and the refrigeration unit building seismic grade glue to transmit radioactive elements, and the electric current of the medium and high frequency current is magnetic. The effect noise transmits radioactive elements outward according to the gas. Based on past work experience, the noise of the refrigeration unit can be manipulated and solved from the following many aspects.

Noise source of decoration background wall: Generally, the noise source of decoration background wall refrigeration unit itself such as insulation cotton is added in the refrigeration unit yard. Insulation cotton is generally made of a composite of sound-absorbing materials and sound-insulating materials. It is made of glass fiber and felt-based sound-absorbing materials. The surface treatment of metal materials is carried out with non-knitted fabrics. It is mainly used on the protective cover of the refrigeration unit to digest and absorb. And reduce its acoustic radiation efficiency. In areas with well-designed insulation cotton above 300Hz, the noise level of the refrigerating unit itself can be reduced by 2~5dB(A), the FFT spectrum analysis peak value is significantly reduced, and the tone is significantly improved.

Weakening the noise source: The mechanical pump value that is easy to ensure before adding refrigerant meets the requirements (about 100Pa), which can significantly reduce the noise of the refrigeration unit (a small amount of gas infiltrates into the system software, which will cause the system software to expand and increase the load. , The noise of the refrigeration unit has risen significantly). According to the work experience data information, under normal circumstances, ensure that the mechanical pump value can reduce the noise by 2 to 3dB(A).
