Decrease in efficiency of screw refrigerators
Thread Content
As the title suggests, screw refrigerators are widely used. However, as their service life increases, their cooling capacity declines. Based on practical production experience, it is estimated that after 3–4 years of use, the cooling capacity drops by 15–20%; but this figure seems a bit high to some. Are there any experts in the refrigerator industry who are aware of this issue?
Check whether the temperature of the condenser after cooling rises, and also check whether the temperature of the economizer after cooling increases; if the temperatures rise, clean them immediately
Solve the problem from both mechanical and heat exchange perspectives
In 3-4 years? In most cases, it is necessary to consider the efficiency of the evaporator, condenser, and oil-gas separator; it may also be caused by refrigerant mixing with other gases.
