Anyone who understands the structure of industrial chillers should know that once the compression ratio of the compressor is too high

Anyone who understands the structure of industrial chillers should know that once the compression ratio of the compressor is too high, it will definitely reduce the work efficiency of the compressor, and the work efficiency of other components will also be reduced due to various reasons, which may cause the industry The refrigeration efficiency of the chiller system drops or even does not refrigerate at all. Therefore, the industrial chiller factory technicians believe that companies should strictly prevent the compression ratio of the industrial chiller factory's chiller from being too high.

　　 1. Disadvantages of too high compression ratio:

　　The compression ratio of any type of chiller should not be too large. The compression ratio is easy to understand, that is, the ratio of the degree of compression of the gas. For example, if the previous gas is 10 and after compression is 1, the compression ratio will be very high. Therefore, it can be concluded that if the compression ratio is high and the value is large, then There is no doubt that the work load of the compressor will be greater.

　　The compression ratio is too high. As mentioned above, the load on the compressor is most likely to increase. When the load is large, the work efficiency will decrease and the consumption of electricity resources will increase.

As the compression ratio of the compressor increases, the internal temperature will be higher, which will not only affect the properties of the refrigerant, but also may cause the viscosity of the lubricating oil to decrease, and the lubricating effect will be lower. Lubricating oil that cannot play its due role in the compressor , It will increase the chance of compressor wear.

In addition, the high pressure, that is, the exhaust pressure, will also become higher due to the increase in compression ratio, which will bring greater heat dissipation burden to the condenser. If the fan or water cooling system cannot improve the heat dissipation capacity accordingly, the heat dissipation effect of the condenser must be poor. The industrial chiller system will not be able to undertake the heat dissipation of the equipment.

　　 2. The solution is as follows:

　　 1. The appropriate refrigerant should be considered to control the compression ratio of the compressor.

　　2. It should be checked whether there is clogging. It is recommended to replace the filter. Replacement of the filter can improve the filter's ability to filter the impurities that may be generated in the industrial chiller system and the impurities that may be generated in the refrigerated lubricating oil, thereby preventing pipelines and valves from clogging.

　　 It is also necessary to consider whether insufficient refrigerant has caused the suction pressure. Excessive suction pressure will lead to problems such as high compression ratio and high exhaust temperature. In other words, the compression ratio and the discharge pressure and temperature can be reduced by increasing the suction pressure.

　　3. The compressor can also be separately cooled, and it can also solve the problems of excessive discharge pressure and excessive discharge temperature generated when the compression ratio is too high.

　　Enterprises should strictly prevent the compression ratio of industrial chillers from being too high to ensure the normal and stable operation of industrial chillers!
