I have chiller carrier 30GH 245 prodialog control systems. When circuit B is running at full load (4 compressors are running), delta T does not maintain, if the EWT is 13c LWT will be 12c.also all compressors are flooding. Checked flow, strainer..Etc. everything ok. The next thing is the superheat is 22c, so the EXV is 95% open. Replaced compressor sensor, and transducer value is correct. So I have doubt about the heatxchanger gasket whether damaged. Anybody has such experience; your any comment would be appreciated.
