Re: Expansion Valve Selection
You will also need an oil separator in case if you switch off one compressor & operate only one compressor with 50% evap load because your suction line is not designed for part load condition .
( on 50% evap load , oil return becomes a problem)
an oil separator means addition of two nrv in discharge line etc ; your accessories increase to protect the compressor . Hence two independent circuits will be simple to operate & maintain
