I need some help diagnosing a built up DX system -
The system is running a Bitzer Semi Hermetic Compressor, liquid line splits into two seperate evaporator coils each has its own TXV and Solenoid control on the liquid line, system is running on R407c and air cooled condenser coil.
Does one calculate super heat the same way as you would on a single TXV system?
Oil in compressor is 'bubbling' or 'frothing' like crazy, is the best place to start diagnosis by check Super heat and Sub cooling?
Suction Pressure is constantly hunting...
Any advice would be appreciated.
