Problems with Freon compressors
Thread Content
Our factory has a \"combined dryer\" (model: KSAD-60WW, manufacturer: Zhejiang Kaishan) used in conjunction with a screw air compressor. We also have a compressor used for handling Freon, and it has been observed that the temperature of the compressor body is high (the water cooling system is working properly). What could be the cause of this? I’m seeking help from experts. Thank you. I don’t know how to send pictures.
What is the temperature? Generally, as long as it doesn’t exceed the upper limit, it’s fine
Based on the available information, it’s not known what this temperature should be; it’s only known that it is higher than that of another unit, whose temperature does not exceed 30 degrees, while this unit’s temperature reaches 65 degrees. Do you have any information on this?
Are you saying the temperature of this compressor is high? Is your compressor a refrigeration unit?
There might be too much oil in the system, resulting in poor heat exchange.
Yes, it’s just like the compressor in a regular air conditioner, only a bit larger. As the temperature of the machine rises, the reading on the high-pressure gauge for the refrigerant increases from 1 MPa to 1.6 MPa, after which the system shuts down.

It is recommended to drain all the Freon from the compressor, then evacuate it before adding new Freon. Of course, you need to locate the leak points first; otherwise, the same problem will arise again in a few days. By the way, does this compressor have any areas with negative pressure? If there is no negative pressure, there’s no need to worry about air entering; if there is negative pressure, it’s probably the issue I mentioned
Has the non-condensable gas been completely removed? Is the lubrication system functioning properly? Is the suction pressure normal? It is necessary to analyze and determine the principle by taking into account the parameters of the entire system.
