I was simply using 134 as a example on retrofitting 410 compressors. Pressures aside, mass flow rates of 134 and 22 should be somewhere in the same neighborhood, unlike 410a. There's no possible way your liquid line could sweat short of a restriction. Liquid line temperature is often 3-10*f Higher than ambient outdoor temperature. If your liquid line is sweating, you have a significant restriction that needs addressed, and may explain your issues with setting subcool. Only exception to this rule are Minisplits, because the metering device is in the outdoor section. The suction/vapor line absolutely will sweat. On other notes, you may see an actual efficiency increase since your condenser is rejecting less heat and is operating more efficiently.
