Hello, I have a Thermo King V-300 refrigeration unit max 20 R 404A refrigerant. The unit is powered by a compressor as well as a 380v network. My problem is that the aggregate is not cooling well, which turned out to be too low a factor (checked with an instrument) and the stairs begin that nothing writes anywhere, how much of this factor should be in the system ??? I would be grateful for any help how much this factor can be or how to check it :)
