oil cooling problem
Dear All,
I started one screw compressor that is designed in condition -10 C as evaporating temp. and +35 as condensing temp. also this compressor is designed with fixed Vi
The pressure of liquid seperator (suction press) was 7 bar(a) in start.
The compressor worked at partial load (about 10% capacity) about 5min. after that high discharge temp. alarm turned up.
I think inner pressure of compessor at oil input of compressor has extra pressure rather discharge press. so oil circulation not been did correctly.
Please advise if you have idea
