Pretty new to working on big commercial equipment most worked on residential equipment.Have a 20 ton 2 stage condensing unit with two 10 ton evaporators. It has a common circuit branching into the two evaporators two txv and one liquid line solenoid valve. First stage compressor is coming on and pumping into the two evaporators at once.
Not 100% sure but shouldn't the evaporators be stage with compressors? If one compressor is running should it only be feeding 1 evap?
