High state compressor oil pressure trip
Hi all, i am new here, wish you guys can give me some ideal and guideline regarding the refrigeration system.
i am troubleshooting a environmental test chamber with cascade system ( H/S R404A, L/S R23, water cool). the problem of this chamber is H/S compressor oil pressure trip.
i couldnt find any problem with H/S refirgeration system, but i found there is a insufficient refrigerant for L/S refrigeration system which is cause by leakage at the compressor discharge service valve.
i fix the leakage and top up R23 for the L/S refrigeration system and i found the H/S working well with no oil pressure trip.
My question is, will the L/S refrigeration system with insufficient gas cause the H/S compressor oil pressure trip, if yes? how?
