The adverse effects of high compression ratio of industrial chillers:

The compression ratio of any type of chiller should not be too large. The compression ratio is easy to understand. It 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.

Too high a compression ratio is most likely to cause the load of the compressor 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 increase the heat dissipation capacity correspondingly, the heat dissipation effect of the condenser must be very poor. The industrial chiller system will not be able to undertake the heat dissipation of the equipment.

So how can companies solve this problem when the compression ratio of the chiller is too high?

1. Consider choosing a suitable refrigerant 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.

Enterprises also need to consider whether insufficient refrigerant is causing the suction pressure, and too high suction pressure will lead to problems such as high compression ratio and high exhaust temperature. In other words, the compression ratio, as well as the exhaust pressure and exhaust temperature can be reduced by increasing the suction pressure.

3. Separate additional cooling of the compressor can be adopted, and it can also solve the problems of excessive exhaust pressure and excessive exhaust temperature generated when the compression ratio is too high.
