The suction gas leaves the evap, goes into an accumulator then the sub-cooler before it gets to the compressor.
the compressor oil has a cooler that uses liquid taken between the drier and s valve, goes thru a solinoid valve and txv, sub-cooler and reenters the suction line between the evap and accumulator.
